Repeatedly fire an action every 10 minutes

Question

I want to fire an action after every 10 minutes of application use.

I want to display a full screen advertisement after every 10 minutes, irrespective of where ViewController of the application is currently at.

Answer 1

You need to use NSTimer with set the timeInterval = 10 and repeats = YES and declare this timer to your didFinishLaunchingWithOptions method. For more information you can read this official documentation of NSTimer .

And also look at How do I use NSTimer?

Answer 2

Try this :

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
        NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
        timer = [NSTimer scheduledTimerWithTimeInterval:600 target:self selector:@selector(doAction) userInfo:nil repeats:YES ];
        [pool release];
}

Hope it will help.
