NSURLSession   通过session创建任务

@property (class, readonly, strong) NSURLSession *sharedSession; 

+ (NSURLSession *)sessionWithConfiguration:(NSURLSessionConfiguration *)configuration;

+ (NSURLSession *)sessionWithConfiguration:(NSURLSessionConfiguration *)configuration delegate:(nullable id <NSURLSessionDelegate>)delegate delegateQueue:(nullable NSOperationQueue *)queue;

@property (readonly, retain) NSOperationQueue *delegateQueue;

@property (nullable, readonly, retain) id <NSURLSessionDelegate> delegate;

@property (readonly, copy) NSURLSessionConfiguration *configuration;

@property (nullable, copy) NSString *sessionDescription;

- (void)finishTasksAndInvalidate;

- (void)invalidateAndCancel;

- (void)flushWithCompletionHandler:(void (^)(void))completionHandler;  

- (void)getTasksWithCompletionHandler:(void (^)(NSArray<NSURLSessionDataTask *> *dataTasks, NSArray<NSURLSessionUploadTask *> *uploadTasks, NSArray<NSURLSessionDownloadTask *> *downloadTasks))completionHandler; 

- (void)getAllTasksWithCompletionHandler:(void (^)(NSArray<__kindof NSURLSessionTask *> *tasks))completionHandler API_AVAILABLE(macos(10.11), ios(9.0), watchos(2.0), tvos(9.0)); /* invokes completionHandler with all outstanding tasks.

NSURLSessionConfiguration 通过configuration创建session

NSURLSessionTask   任务

NSURLSessionDataTask : NSURLSessionTask  普通任务

NSURLSessionUploadTask : NSURLSessionDataTask 上传任务

NSURLSessionDownloadTask : NSURLSessionTask  下载任务

NSURLSessionStreamTask : NSURLSessionTask

NSURLSessionDelegate  session代理

NSURLSessionTaskDelegate <NSURLSessionDelegate>

NSURLSessionDataDelegate <NSURLSessionTaskDelegate>

NSURLSessionDownloadDelegate <NSURLSessionTaskDelegate>

NSURLSessionStreamDelegate <NSURLSessionTaskDelegate>
