Restart iphone application from the very beginning
提问by sexitrainer
when i close my application (via HOME button) and open it up again, how do i force the application to restart from the very beginning view and not from the last location that was shown (before it was closed)? is it a setting in the project?
当我关闭我的应用程序（通过 HOME 按钮）并再次打开它时，我如何强制应用程序从最开始的视图而不是从显示的最后一个位置（关闭之前）重新启动？它是项目中的设置吗？

Set the app's info.plist key: UIApplicationExitsOnSuspend to True.
将应用程序的 info.plist 键：UIApplicationExitsOnSuspend 设置为 True。

This is caused by multi-tasking, i.e. the app isn't properly quitting.
这是由多任务处理引起的，即应用程序没有正确退出。
To ensure that it pops back, try this in the applicationWillEnterForeground, like so:
为确保它弹出，请在 中尝试此操作applicationWillEnterForeground，如下所示：
- (void)applicationWillEnterForeground:(UIApplication *)application
{
[self.navigationController popToRootViewControllerAnimated:NO];
}
Or a very quick and dirty way, is to actually quit the application when it enters the background (note this probably isn't the best way).
或者一种非常快速和肮脏的方法，是在应用程序进入后台时实际退出应用程序（注意这可能不是最好的方法）。
- (void)applicationDidEnterBackground:(UIApplication *)application
{
[[NSThread mainThread] exit];
// OR
exit(0);
}

Look for a notification from the phone letting you know that the phone "Became Active" which will only happen if the app was running, then sent to background, then pulled up again. Once you know it has become active again you can push your Home view.
寻找来自手机的通知，让您知道手机“变得活跃”，这只会在应用程序运行时发生，然后发送到后台，然后再次拉起。一旦您知道它再次变为活动状态，您就可以推送您的主页视图。
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification {
if (application.applicationState == UIApplicationStateInactive ) {
//application has been sent to the background
}
if(application.applicationState == UIApplicationStateActive ) {
//The application has become active an alert view or do something appropriate.
//push home view here.
}
}
