在自定义线程上调度完成块
每当使用 AFNetworking 时,都会在 AFNetworking 提供的自定义线程上调度该调用。当调用返回到完成块时,它将在主线程上执行。
此示例设置一个调度到完成块的自定义线程:
AFNetworking 2.xx:
// Create dispatch_queue_t with your name and DISPATCH_QUEUE_SERIAL as for the flag
dispatch_queue_t myQueue = dispatch_queue_create("com.CompanyName.AppName.methodTest",
DISPATCH_QUEUE_SERIAL);
// init AFHTTPRequestOperation of AFNetworking
operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
// Set the FMDB property to run off the main thread
[operation setCompletionQueue:myQueue];
AFNetworking 3.xx:
AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc] init];
[self setCompletionQueue:myQueue];
