GCD方法，通过向主线程队列发送一个block块，使block里的方法可以在主线程中执行。 dispatch_async(dispatch_get_main_queue(), ^{ //需要执行的方法 }); NSOperation 方法 NSOperationQueue *mainQueue = [NSOperationQueue mainQueue]; //主队列 NSBlockOperation *operation = [NSBlockOperation blockOperationWithBlock:^{ //需要执行的方法 }]; [mainQueue addOperation:operation]; NSThread 方法 [self performSelector:@selector(method) onThread:[NSThread mainThread] withObject:nil waitUntilDone:YES modes:nil]; [self performSelectorOnMainThread:@selector(method) withObject:nil waitUntilDone:YES]; [[NSThread mainThread] performSelector:@selector(method) withObject:nil]; RunLoop方法 [[NSRunLoop mainRunLoop] performSelector:@selector(method) withObject:nil];
