If you would like to load an Ad after certain time interval in your App, for eg. 30 seconds after App Launch. You can use the following code to do so –
Put the code inside of your AppDelegate.m applicationDidBecomeActive –
[NSTimer scheduledTimerWithTimeInterval:30.0 target:self selector:@selector(fun) userInfo:nil repeats:NO];
Put this code anywhere in the same file and put the Ad code inside it –
// Ad Code
The NSTimer object above will call the “fun” function after the specified time interval and your Ad will get load up.
