NSURLSession设计
- NSURLSession
- NSURLSessionTask
- NSURLSessionConfiguration
- 代理方法
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration]; // #1
NSURLSession *session = [NSURLSession sessionWithConfiguration:configuration
delegate:self
delegateQueue:[NSOperationQueue mainQueue]]; // #2
NSURLSessionDataTask *task = [session dataTaskWithURL:[[NSURL alloc]initWithString:@""]]; // #3
[task resume];
1.Configuration
defaultSessionConfiguration 默认
ephemeralSessionConfiguration 私密的
backgroundSessionConfigurationWithIdentifier
timeoutIntervalForRequest
2.Delegate DelegateQueue
3. Session
4. Task
NSURLSessionTask：超类
NSURLSessionDataTask：请求
NSURLSessionUploadTask：上传（父类是NSURLSessionDataTask
NSURLSessionDownloadTask：下载
Configuration进行配置
Session将Configuration Delegate DelegateQueue 进行关联 返回task
Task是任务类 启动暂停等方法
AFNetworking的设计
总结
static NSString * const
static inline void函数
static NSString * AFCreateMultipartFormBoundary()
[[NSNotificationCenter defaultCenter] postNotificationName:AFNetworkingTaskDidCompleteNotification object:task userInfo:userInfo];
代码注释
枚举类型
/**
Whether or not the network is currently reachable.
*/
@property (readonly, nonatomic, assign, getter = isReachable) BOOL reachable;
// setter
self.reachable = YES;
// getter
if (self.isReachable) {}
pragma mark -
