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. + + ## NSURLConnection Delegate Methods + + `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. + + ## App Extensions + + When using AFNetworking in an App Extension, `#define AF_APP_EXTENSIONS` to avoid using unavailable APIs. + + ## 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. + */ + +@interface AFURLConnectionOperation : NSOperation + +///------------------------------- +/// @name Accessing Run Loop Modes +///------------------------------- + +/** + The run loop modes in which the operation will run on the network thread.
