AFNetworking 2.0 + NSURLSession

Transcript

1. AFNetworking 2.0 + NSURLSession
2. AFNetworking?
3. “A delightful networking framework for iOS and OSX.” “AFNetworking is one of the most widely used open source projects for iOS and Mac OS X development.” “With over 8,700 stars, 2,200 forks, and 130 contributors, the project is also among the most active and influential in the community.”
4. How has it started?
5. NSURLConnection NSOperation
7. That’s it! A Network API builded on top of Network Foundation that takes care of the hard work and gives you friendly interfaces.
8. NSURLSession
9. “..provides an API for downloading content via HTTP.”
10. NSURLSession NSURLSessionConfiguration NSURLSessionTask DataTask DownloadTask UploadTask <NSURLSessionDelegate> <NSURLSessionTaskDelegate> DataDelegate DownloadDelegate UploadDelegate D e l e g a t e
11. NSURLSessionConfiguration Cache Policy Timeout Interval Allows Celullar Network Cookies Storage NSURLCache *You cannot modify a configuration after your session was created
12. NSURLSessionConfiguration Default configuration: Disk-based cache, credentials on the user keychain Ephemeral configuration: All caches, credentials storage, and so on are kept in RAM and dies when the session is invalidated. Background configuration: Similar to default, supports requests while app is suspended
13. NSURLSessionConfiguration
14. NSURLSession NSURLSessionConfiguration NSURLSessionTask DataTask DownloadTask UploadTask <NSURLSessionDelegate> <NSURLSessionTaskDelegate> DataDelegate DownloadDelegate UploadDelegate D e l e g a t e
15. NSURLSessionTask DataTask DownloadTask UploadTask
16. NSURLSessionDataTask: - Used to send/receive data using NSData objects - Not backgroundable NSURLSessionDownloadTask: - Donwloads data into a local file - Backgroundable NSURLSessionUploadTask: - Uploads data from a local file - Backgroundable *Performed asynchronously by default
17. NSURLSession NSURLSessionConfiguration NSURLSessionTask DataTask DownloadTask UploadTask <NSURLSessionDelegate> <NSURLSessionTaskDelegate> DataDelegate DownloadDelegate UploadDelegate D e l e g a t e
18. A NSURLConnection replacement. - Per sessions configurations: Authentication, cookies storage, NSURLCache, and others - Based on tasks

20. NSURLSessionDelegate • URLSession:didBecomeInvalidWithError: • URLSession:didReceiveChallenge:completionHandler: 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:
21. <NSURLSessionDelegate> - 2 methods <NSURLSessionTaskDelegate> - 5 methods <NSURLSessionDataDelegate> - 4 methods <NSURLSessionDownloadDelegate> - 3 methods 14 methods
23. iOS 6 and Mac OS X 10.8 Moutain Lion Xcode 5 NSURLSession & NSURLConnection Serialization Modules UIKit Extensions Realtime
24. Coming from 1.0... Will keep compatibilty with NSURLConnection and NSURLSession at the same time No more AFHTTPClient - Too many roles to one class, this was split up into another classes
25. Introducing … AFURLSessionManager
26. Highlights Block based callbacks Default expected implementation Provides methods for session management
27. AFURLSessionManager NSURLSessionConfiguration NSURLSessionTask DataTask DownloadTask UploadTask Callback blocks
28. AFHTTPSessionManager ◦ NSURLSesssion *managedSession; ◦ NSURL *baseURL; - Provides methods for HTTP requests (GET, POST, PUT, etc) with serialized response and request. - No NSData handling
33. Serialization
34. Based on two Protocols: <AFURLRequestSerializer> & <AFURLResponseSerializer>
36. - Shared between operations and tasks - Protocols instead of subclasses - More pluggable to specific needs
37. Built-in serializers
38. Request serializers: AFJSONRequestSerializer AFPropertyListRequestSerializer
39. Response serializers: AFJSONResponseSerializer AFPropertyListResponseSerializer AFXMLDocumentResponseSerializer AFXMLParserResponseSerializer AFImageResponseSerializer
41. AFURLRequestOperationManager iOS 6
43. Coming from AFHTTPClient... - Follows the new serializer concept - HTTP request methods (GET, POST, etc) now returns the operation that was just created.
44. AFHTTPRequestOperation
46. - No more classes for each kind of serializer. (Also follows the new serializer concept)
47. Reachability
48. AFNetworkReachabilityManager - Monitors network status while providing notifications and callbacks blocks for status changes. - A property of AFURLSessionManager and AFURLConnectionManager
50. UIKit Extensions Network Activity Indicator UIImageView UIActivityIndicatorView UIProgressView UIWebView
