UIKit密钥在info.plist文件中丢失

Question

I want to add UIApplicationExitsOnSuspend key in info.plist file

but all the UI related keys are missing.

What should be done to get UI related keys in info.plist file

I have default frameworks uikit, foundation and coregraphics added to my project.

Answer 1

If you look in the project.xcodeproj file, search for Info.plist. The entry is probably missing this:

plistStructureDefinitionIdentifier = "com.apple.xcode.plist.structure-definition.iphone.info-plist";

Answer 2

If you have created your project for an earlier iOS version, it is still made for this and doesn't recognize the new keys. Try this: Open your Info.plist as a plain text file and insert following text to it.

<key>UIApplicationExitsOnSuspend</key>
<true/>

Save the file and any the app closes now on suspend.
