iphone - 检测 performSelectorInBackground 结束 :withObject:

Question

我的 iOS 应用程序中有一个异步服务器请求:

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

如何检测此操作的结束？

Answer 1

在 doSomething 方法的末尾调用？!

- (void)doSomething {
    // Thread starts here

    // Do something

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