call method every 5 minutes in my UIView

I want to call a certain method in my UIVi开发者_如何转开发ew code say every 5 minutes - how do I accomplish that?

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
}

You can use NSTimer to do this.

http://developer.apple.com/library/mac/#documentation/Cocoa/Reference/Foundation/Classes/NSTimer_Class/Reference/NSTimer.html

Specifically, the timerWithTimeInterval:target:selector:userInfo:repeats: class method.

There is an easy way to do this, in you update method

-(void)update{
     //Your update methods here
     [self performSelector:@selector(update) withObject:nil afterDelay:300.0];
}
