-/**
- `AFHTTPRequestOperationManager` encapsulates the common patterns of communicating with a web application over HTTP, including request creation, response serialization, network reachability monitoring, and security, as well as request operation management.
-
- ## Subclassing Notes
-
- Developers targeting iOS 7 or Mac OS X 10.9 or later that deal extensively with a web service are encouraged to subclass `AFHTTPSessionManager`, providing a class method that returns a shared singleton object on which authentication and other configuration can be shared across the application.
-
- For developers targeting iOS 6 or Mac OS X 10.8 or earlier, `AFHTTPRequestOperationManager` may be used to similar effect.
-
- ## Methods to Override
-
- To change the behavior of all request operation construction for an `AFHTTPRequestOperationManager` subclass, override `HTTPRequestOperationWithRequest:success:failure`.
-
- ## Serialization
-
- Requests created by an HTTP client will contain default headers and encode parameters according to the `requestSerializer` property, which is an object conforming to `<AFURLRequestSerialization>`.
-
- Responses received from the server are automatically validated and serialized by the `responseSerializers` property, which is an object conforming to `<AFURLResponseSerialization>`
-
- ## URL Construction Using Relative Paths
-
- For HTTP convenience methods, the request serializer constructs URLs from the path relative to the `-baseURL`, using `NSURL +URLWithString:relativeToURL:`, when provided. If `baseURL` is `nil`, `path` needs to resolve to a valid `NSURL` object using `NSURL +URLWithString:`.
-
- Below are a few examples of how `baseURL` and relative paths interact:
-
-    NSURL *baseURL = [NSURL URLWithString:@"http://example.com/v1/"];
-    [NSURL URLWithString:@"foo" relativeToURL:baseURL];                  // http://example.com/v1/foo
-    [NSURL URLWithString:@"foo?bar=baz" relativeToURL:baseURL];          // http://example.com/v1/foo?bar=baz
-    [NSURL URLWithString:@"/foo" relativeToURL:baseURL];                 // http://example.com/foo
-    [NSURL URLWithString:@"foo/" relativeToURL:baseURL];                 // http://example.com/v1/foo
-    [NSURL URLWithString:@"/foo/" relativeToURL:baseURL];                // http://example.com/foo/
-    [NSURL URLWithString:@"http://example2.com/" relativeToURL:baseURL]; // http://example2.com/
-
- Also important to note is that a trailing slash will be added to any `baseURL` without one. This would otherwise cause unexpected behavior when constructing URLs using paths without a leading slash.
-
- ## Network Reachability Monitoring
-
- Network reachability status and change monitoring is available through the `reachabilityManager` property. Applications may choose to monitor network reachability conditions in order to prevent or suspend any outbound requests. See `AFNetworkReachabilityManager` for more details.
-
- ## NSSecureCoding & NSCopying Caveats
-
- `AFHTTPRequestOperationManager` conforms to the `NSSecureCoding` and `NSCopying` protocols, allowing operations to be archived to disk, and copied in memory, respectively. There are a few minor caveats to keep in mind, however:
-
- - Archives and copies of HTTP clients will be initialized with an empty operation queue.
- - NSSecureCoding cannot serialize / deserialize block properties, so an archive of an HTTP client will not include any reachability callback block that may be set.

- `AFNetworkActivityIndicatorManager` manages the state of the network activity indicator in the status bar. When enabled, it will listen for notifications indicating that a network request operation has started or finished, and start or stop animating the indicator accordingly. The number of active requests is incremented and decremented much like a stack or a semaphore, and the activity indicator will animate so long as that number is greater than zero.
-
- You should enable the shared instance of `AFNetworkActivityIndicatorManager` when your application finishes launching. In `AppDelegate application:didFinishLaunchingWithOptions:` you can do so with the following code:
-
-    [[AFNetworkActivityIndicatorManager sharedManager] setEnabled:YES];
-
- By setting `enabled` to `YES` for `sharedManager`, the network activity indicator will show and hide automatically as requests start and finish. You should not ever need to call `incrementActivityCount` or `decrementActivityCount` yourself.
-

- `AFURLConnectionOperation` is a subclass of `NSOperation` that implements `NSURLConnection` delegate methods.
-
- ## Subclassing Notes
-
- This is the base class of all network request operations. You may wish to create your own subclass in order to implement additional `NSURLConnection` delegate methods (see "`NSURLConnection` Delegate Methods" below), or to provide additional properties and/or class constructors.
-
- If you are creating a subclass that communicates over the HTTP or HTTPS protocols, you may want to consider subclassing `AFHTTPRequestOperation` instead, as it supports specifying acceptable content types or status codes.

- `AFURLConnectionOperation` implements the following `NSURLConnection` delegate methods:
-
- - `connection:didReceiveResponse:`
- - `connection:didReceiveData:`
- - `connectionDidFinishLoading:`
- - `connection:didFailWithError:`
- - `connection:didSendBodyData:totalBytesWritten:totalBytesExpectedToWrite:`
- - `connection:willCacheResponse:`
- - `connectionShouldUseCredentialStorage:`
- - `connection:needNewBodyStream:`
- - `connection:willSendRequestForAuthenticationChallenge:`
-
- If any of these methods are overridden in a subclass, they _must_ call the `super` implementation first.
-
- ## Callbacks and Completion Blocks
-
- The built-in `completionBlock` provided by `NSOperation` allows for custom behavior to be executed after the request finishes. It is a common pattern for class constructors in subclasses to take callback block parameters, and execute them conditionally in the body of its `completionBlock`. Make sure to handle cancelled operations appropriately when setting a `completionBlock` (i.e. returning early before parsing response data). See the implementation of any of the `AFHTTPRequestOperation` subclasses for an example of this.
-
- Subclasses are strongly discouraged from overriding `setCompletionBlock:`, as `AFURLConnectionOperation`'s implementation includes a workaround to mitigate retain cycles, and what Apple rather ominously refers to as ["The Deallocation Problem"](http://developer.apple.com/library/ios/#technotes/tn2109/).
-
- ## SSL Pinning
-
- Relying on the CA trust model to validate SSL certificates exposes your app to security vulnerabilities, such as man-in-the-middle attacks. For applications that connect to known servers, SSL certificate pinning provides an increased level of security, by checking server certificate validity against those specified in the app bundle.
-
- SSL with certificate pinning is strongly recommended for any application that transmits sensitive information to an external webservice.
-
- Connections will be validated on all matching certificates with a `.cer` extension in the bundle root.
-
- ## NSCoding & NSCopying Conformance
-
- `AFURLConnectionOperation` conforms to the `NSCoding` and `NSCopying` protocols, allowing operations to be archived to disk, and copied in memory, respectively. However, because of the intrinsic limitations of capturing the exact state of an operation at a particular moment, there are some important caveats to keep in mind:
-
- ### NSCoding Caveats
-
- - Encoded operations do not include any block or stream properties. Be sure to set `completionBlock`, `outputStream`, and any callback blocks as necessary when using `-initWithCoder:` or `NSKeyedUnarchiver`.
- - Operations are paused on `encodeWithCoder:`. If the operation was encoded while paused or still executing, its archived state will return `YES` for `isReady`. Otherwise, the state of an operation when encoding will remain unchanged.
-
- ### NSCopying Caveats
-
- - `-copy` and `-copyWithZone:` return a new operation with the `NSURLRequest` of the original. So rather than an exact copy of the operation at that particular instant, the copying mechanism returns a completely new instance, which can be useful for retrying operations.
- - A copy of an operation will not include the `outputStream` of the original.
- - Operation copies do not include `completionBlock`, as it often strongly captures a reference to `self`, which would otherwise have the unintuitive side-effect of pointing to the _original_ operation when copied.

-/**
- `AFURLSessionManager` creates and manages an `NSURLSession` object based on a specified `NSURLSessionConfiguration` object, which conforms to `<NSURLSessionTaskDelegate>`, `<NSURLSessionDataDelegate>`, `<NSURLSessionDownloadDelegate>`, and `<NSURLSessionDelegate>`.
-
- ## Subclassing Notes
-
- This is the base class for `AFHTTPSessionManager`, which adds functionality specific to making HTTP requests. If you are looking to extend `AFURLSessionManager` specifically for HTTP, consider subclassing `AFHTTPSessionManager` instead.
-
- ## NSURLSession & NSURLSessionTask Delegate Methods
-
- `AFURLSessionManager` implements the following delegate methods:
-
- ### `NSURLSessionDelegate`
-
- - `URLSession:didBecomeInvalidWithError:`
- - `URLSession:didReceiveChallenge:completionHandler:`
- - `URLSessionDidFinishEventsForBackgroundURLSession:`
-
- ### `NSURLSessionTaskDelegate`
-
- - `URLSession:willPerformHTTPRedirection:newRequest:completionHandler:`
- - `URLSession:task:didReceiveChallenge:completionHandler:`
- - `URLSession:task:didSendBodyData:totalBytesSent:totalBytesExpectedToSend:`
- - `URLSession:task:didCompleteWithError:`
-
- ### `NSURLSessionDataDelegate`
-
- - `URLSession:dataTask:didReceiveResponse:completionHandler:`
- - `URLSession:dataTask:didBecomeDownloadTask:`
- - `URLSession:dataTask:didReceiveData:`
- - `URLSession:dataTask:willCacheResponse:completionHandler:`
-
- ### `NSURLSessionDownloadDelegate`
-
- - `URLSession:downloadTask:didFinishDownloadingToURL:`
- - `URLSession:downloadTask:didWriteData:totalBytesWritten:totalBytesWritten:totalBytesExpectedToWrite:`
- - `URLSession:downloadTask:didResumeAtOffset:expectedTotalBytes:`
-
- If any of these methods are overridden in a subclass, they _must_ call the `super` implementation first.
-
- ## Network Reachability Monitoring
-
- Network reachability status and change monitoring is available through the `reachabilityManager` property. Applications may choose to monitor network reachability conditions in order to prevent or suspend any outbound requests. See `AFNetworkReachabilityManager` for more details.
-
- ## NSCoding Caveats
-
- - Encoded managers do not include any block properties. Be sure to set delegate callback blocks when using `-initWithCoder:` or `NSKeyedUnarchiver`.
-
- ## NSCopying Caveats
-
- - `-copy` and `-copyWithZone:` return a new manager with a new `NSURLSession` created from the configuration of the original.
- - Operation copies do not include any delegate callback blocks, as they often strongly captures a reference to `self`, which would otherwise have the unintuitive side-effect of pointing to the _original_ session manager when copied.
-
- @warning Managers for background sessions must be owned for the duration of their use. This can be accomplished by creating an application-wide or shared singleton instance.

-/**
- `AFHTTPRequestOperationManager` encapsulates the common patterns of communicating with a web application over HTTP, including request creation, response serialization, network reachability monitoring, and security, as well as request operation management.
-
- ## Subclassing Notes
-
- Developers targeting iOS 7 or Mac OS X 10.9 or later that deal extensively with a web service are encouraged to subclass `AFHTTPSessionManager`, providing a class method that returns a shared singleton object on which authentication and other configuration can be shared across the application.
-
- For developers targeting iOS 6 or Mac OS X 10.8 or earlier, `AFHTTPRequestOperationManager` may be used to similar effect.
-
- ## Methods to Override
-
- To change the behavior of all request operation construction for an `AFHTTPRequestOperationManager` subclass, override `HTTPRequestOperationWithRequest:success:failure`.
-
- ## Serialization
-
- Requests created by an HTTP client will contain default headers and encode parameters according to the `requestSerializer` property, which is an object conforming to `<AFURLRequestSerialization>`.
-
- Responses received from the server are automatically validated and serialized by the `responseSerializers` property, which is an object conforming to `<AFURLResponseSerialization>`
-
- ## URL Construction Using Relative Paths
-
- For HTTP convenience methods, the request serializer constructs URLs from the path relative to the `-baseURL`, using `NSURL +URLWithString:relativeToURL:`, when provided. If `baseURL` is `nil`, `path` needs to resolve to a valid `NSURL` object using `NSURL +URLWithString:`.
-
- Below are a few examples of how `baseURL` and relative paths interact:
-
-    NSURL *baseURL = [NSURL URLWithString:@"http://example.com/v1/"];
-    [NSURL URLWithString:@"foo" relativeToURL:baseURL];                  // http://example.com/v1/foo
-    [NSURL URLWithString:@"foo?bar=baz" relativeToURL:baseURL];          // http://example.com/v1/foo?bar=baz
-    [NSURL URLWithString:@"/foo" relativeToURL:baseURL];                 // http://example.com/foo
-    [NSURL URLWithString:@"foo/" relativeToURL:baseURL];                 // http://example.com/v1/foo
-    [NSURL URLWithString:@"/foo/" relativeToURL:baseURL];                // http://example.com/foo/
-    [NSURL URLWithString:@"http://example2.com/" relativeToURL:baseURL]; // http://example2.com/
-
- Also important to note is that a trailing slash will be added to any `baseURL` without one. This would otherwise cause unexpected behavior when constructing URLs using paths without a leading slash.
-
- ## Network Reachability Monitoring
-
- Network reachability status and change monitoring is available through the `reachabilityManager` property. Applications may choose to monitor network reachability conditions in order to prevent or suspend any outbound requests. See `AFNetworkReachabilityManager` for more details.
-
- ## NSSecureCoding & NSCopying Caveats
-
- `AFHTTPRequestOperationManager` conforms to the `NSSecureCoding` and `NSCopying` protocols, allowing operations to be archived to disk, and copied in memory, respectively. There are a few minor caveats to keep in mind, however:
-
- - Archives and copies of HTTP clients will be initialized with an empty operation queue.
- - NSSecureCoding cannot serialize / deserialize block properties, so an archive of an HTTP client will not include any reachability callback block that may be set.

-/**
- `AFHTTPSessionManager` is a subclass of `AFURLSessionManager` with convenience methods for making HTTP requests. When a `baseURL` is provided, requests made with the `GET` / `POST` / et al. convenience methods can be made with relative paths.
-
- ## Subclassing Notes
-
- Developers targeting iOS 7 or Mac OS X 10.9 or later that deal extensively with a web service are encouraged to subclass `AFHTTPSessionManager`, providing a class method that returns a shared singleton object on which authentication and other configuration can be shared across the application.
-
- For developers targeting iOS 6 or Mac OS X 10.8 or earlier, `AFHTTPRequestOperationManager` may be used to similar effect.
-
- ## Methods to Override
-
- To change the behavior of all data task operation construction, which is also used in the `GET` / `POST` / et al. convenience methods, override `dataTaskWithRequest:completionHandler:`.
-
- ## Serialization
-
- Requests created by an HTTP client will contain default headers and encode parameters according to the `requestSerializer` property, which is an object conforming to `<AFURLRequestSerialization>`.
-
- Responses received from the server are automatically validated and serialized by the `responseSerializers` property, which is an object conforming to `<AFURLResponseSerialization>`
-
- ## URL Construction Using Relative Paths
-
- For HTTP convenience methods, the request serializer constructs URLs from the path relative to the `-baseURL`, using `NSURL +URLWithString:relativeToURL:`, when provided. If `baseURL` is `nil`, `path` needs to resolve to a valid `NSURL` object using `NSURL +URLWithString:`.
-
- Below are a few examples of how `baseURL` and relative paths interact:
-
-    NSURL *baseURL = [NSURL URLWithString:@"http://example.com/v1/"];
-    [NSURL URLWithString:@"foo" relativeToURL:baseURL];                  // http://example.com/v1/foo
-    [NSURL URLWithString:@"foo?bar=baz" relativeToURL:baseURL];          // http://example.com/v1/foo?bar=baz
-    [NSURL URLWithString:@"/foo" relativeToURL:baseURL];                 // http://example.com/foo
-    [NSURL URLWithString:@"foo/" relativeToURL:baseURL];                 // http://example.com/v1/foo
-    [NSURL URLWithString:@"/foo/" relativeToURL:baseURL];                // http://example.com/foo/
-    [NSURL URLWithString:@"http://example2.com/" relativeToURL:baseURL]; // http://example2.com/
-
- Also important to note is that a trailing slash will be added to any `baseURL` without one. This would otherwise cause unexpected behavior when constructing URLs using paths without a leading slash.
-
- @warning Managers for background sessions must be owned for the duration of their use. This can be accomplished by creating an application-wide or shared singleton instance.

- `AFNetworkActivityIndicatorManager` manages the state of the network activity indicator in the status bar. When enabled, it will listen for notifications indicating that a network request operation has started or finished, and start or stop animating the indicator accordingly. The number of active requests is incremented and decremented much like a stack or a semaphore, and the activity indicator will animate so long as that number is greater than zero.
-
- You should enable the shared instance of `AFNetworkActivityIndicatorManager` when your application finishes launching. In `AppDelegate application:didFinishLaunchingWithOptions:` you can do so with the following code:
-
-    [[AFNetworkActivityIndicatorManager sharedManager] setEnabled:YES];
-
- By setting `enabled` to `YES` for `sharedManager`, the network activity indicator will show and hide automatically as requests start and finish. You should not ever need to call `incrementActivityCount` or `decrementActivityCount` yourself.
-
