NSURLSession每次发送过一个请求以后，都须要调用一次[session finishTasksAndInvalidate];来防止内存泄漏。google

示例代码：（参考连接 https://stackoverflow.com/questions/30106960/nsurlsession-memory-leak）spa

NSURLSessionConfiguration* config = [NSURLSessionConfigurationdefaultSessionConfiguration];
NSURLSession* session = [NSURLSession sessionWithConfiguration:config];
NSURLRequest* request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.google.com"]];
NSURLSessionDataTask* sessionDataTask = [session dataTaskWithRequest:request
                                           completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
   // handle response...
}];
[sessionDataTask resume];
[session finishTasksAndInvalidate];
