Question

I want to call a certain method in my UIView code say every 5 minutes – how do I accomplish that?

Answer 1

You can use an NSTimer:

Put the following in your viewDidLoad (where 300 is the number of seconds):

[NSTimer scheduledTimerWithTimeInterval:300.0f
             target:self
         selector:@selector(updateMethod:)
         userInfo:nil
         repeats:YES];

And then create your update method:

- (void)updateMethod:(NSTimer *)theTimer {
    // Your code goes here
}
