iPhone SDK退出

Question

我找到了许多应用程序，你可以按下按钮或类似的东西，应用程序将终止并带你回到主屏幕。我该怎么做？

Answer 1

出口（0）;

这可以退出应用程序。

再次，我认为最好的方式如下：

    //@step invoke the normal routine applicationWillTerminate
if ([[UIApplication sharedApplication].delegate respondsToSelector:@selector(applicationWillTerminate:)]) 
{
    [[UIApplication sharedApplication].delegate performSelector:@selector(applicationWillTerminate:) withObject:[UIApplication sharedApplication]];
}
//@step force quite app
kill(getpid(), SIGINT); 

我从溢出的其他帖子中得到了它：D
