objective-c - 从 XCode 关闭模拟器时是否有运行方法？

Question

这纯粹是出于开发目的，因为在您可以使用的设备上

-(void)applicationDidEnterBackground:(UIApplication *)application

但是我经常只是在 XCode 中点击停止按钮来停止模拟器的运行，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？

I think this Apple Q&A will be interesting: Detecting the Debugger

I found it mid-way through this article:

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
