检测performSelectorInBackground的结束：withObject： [英] Detect end of performSelectorInBackground:withObject:

问题描述

我的iOS应用程序中有异步服务器请求：

I have an asynchronous server request in my iOS app:

[self performSelectorInBackground:@selector(doSomething) withObject:nil];

如何检测此操作的结束？

How can I detect the end of this operation?

推荐答案

在doSomething方法结束时拨打电话？！

Put a call at the end of the doSomething method?!

- (void)doSomething {
    // Thread starts here

    // Do something

    // Thread ends here
    [self performSelectorOnMainThread:@selector(doSomethingDone) withObject:nil waitUntilDone:NO];
}
