这纯粹是为了开发目的，因为在设备上你可以使用

-(void)applicationDidEnterBackground:(UIApplication *)application

但我经常只是点击 XCode 中的停止按钮来停止模拟器运行，我需要某种方法来运行，所以它可以告诉数据库当前玩家已经停止播放，知道该怎么做吗？

最佳答案

我认为这个 Apple 问答会很有趣:Detecting the Debugger

我在 this article 的中途找到了它:

Apple provided a little function to determine whether the debugger is attached here. So as soon as my application starts in the Simulator, I'll let it wait:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions

{

#if DEBUG

// Wait max. 10 secs for debugger to attach again:

double waitTime = 0.0;
while (AmIBeingDebugged() == NO && waitTime < 15.0)
{
    [NSThread sleepForTimeInterval:0.25];
    waitTime += 0.25;
}

#endif
