Question

Currently, my iPad application implements multitasking. However, I would like to offer the user an option to disable multitasking. Is this possible, given the fact that you cannot modify the Info.plist dictionary where the UIApplicationExistsOnSuspend key is set?

Answer 1

Well, you could set a flag in your application delegate that would simply exit your app when the flag is TRUE within the delegate method applicationDidEnterBackground:, like this:

@interface MyAppDelegate : NSObject <UIApplicationDelegate> {
   BOOL multitasking;
   ...
}
...
@end

@implementation MyAppDelegate

- (void) applicationDidEnterBackground:(UIApplication *)application {
   if(!multitasking) {
      exit(0);
      return;
   }
   ...
}

...
@end
