如何告诉 iOS 我不希望应用程序留在后台? [英] How do I tell iOS that I do not want the app to stay in the background?

问题描述

有没有办法告诉 iOS 我不希望我的应用留在后台?换句话说，我可以告诉我的应用在进入后台时自行退出吗?

Is there a way to tell iOS that I do not want my app to stay in the background? In other word, can I tell my app to quit itself whenever getting into the background?

我在我的 UITbarController 的一个选项卡中使用 ABPeoplePickerNavigationController.但是，只要到达 [ABMembersViewController applicationDidResume]，它就会崩溃并出现 EXC_BAD_ACCESS.

I am using ABPeoplePickerNavigationController in one of the tabs in my UITbarController. However, it crashes with a EXC_BAD_ACCESS whenever it reaches [ABMembersViewController applicationDidResume].

堆栈跟踪来了:

0x00cc5994  <+0034>  mov    0x8(%eax),%eax
0x00cc5991  <+0031>  mov    0x8(%ebp),%eax
0x00cc598d  <+0027>  mov    %eax,0x4(%esp)
0x00cc5987  <+0021>  mov    0x4e082(%ebx),%eax
0x00cc597f  <+0013>  movl   $0x0,0x8(%esp)
0x00cc597e  <+0012>  pop    %ebx
ABCGetGroupCount
-[ABAccountsAndGroupDataSource hasMultipleAccountsOrGroups]
-[ABMembersViewController updateNavigationButtonsInSearchMode:animated:]
-[ABMembersViewController updateNavigationButtonsAnimated:]
-[ABMembersViewController applicationDidResume]

因此，为了解决这个问题，我认为如果我能够强制应用自行终止，我可以很好地阻止程序通过这部分代码.

So, in order to work around it, I figure that if I am able to force the app to terminate itself, I can beautifully prevent the program to go through this part of the code.

推荐答案

在 info.plist 中，将 UIApplicationExitsOnSuspend 设置为 yes

in your info.plist, set UIApplicationExitsOnSuspend to yes
