检查当前线程是否为主线程 [英] Check whether or not the current thread is the main thread

问题描述

有什么办法可以检查当前线程是否是Objective-C中的主线程?

Is there any way to check whether or not the current thread is the main thread in Objective-C?

我想做这样的事情.

  - (void)someMethod
  {
    if (IS_THIS_MAIN_THREAD?) {
      NSLog(@"ok. this is main thread.");
    } else {
      NSLog(@"don't call this method from other thread!");
    }
  }

推荐答案

看看 NSThread API 文档.

Have a look at the NSThread API documentation.

有像

- (BOOL)isMainThread

+ (BOOL)isMainThread

和 + (NSThread *)mainThread
