iphone - “PostMessage”从工作线程向主 GUI 线程发送消息

Question

我创建了一个线程，现在我想从线程发送消息（执行特定事件）到主 GUI 线程，以便 GUI 线程可以执行我的消息。谁能告诉我如何在 iphone 中执行此操作（目标 C)

Answer 1

  //This will call selected method on main thread and you can do what ever you want to do in your selected method.

[self performSelectorOnMainThread:@selector(yourmethod) withObject:yourobject waitUntilDone:NO];

希望对你有帮助..

Answer 2

您可以使用 GCD 和块

dispatch_async(dispatch_get_main_queue(), ^{
    // UI code to run on main thread
});
