How to auto scroll UIScrollView using timer

Question

Hi,

I have scrollview to show images. I need timer to show images one after another for every 5 seconds. How to initiate UIScrollView event to move next after 5 sec using timer?

Thank you vb

Add the variable int h to your interface, and yourScrollView as a property. Then:

[NSTimer scheduledTimerWithTimeInterval:5.0 target:self selector:@selector(onTimer) userInfo:nil repeats:YES];

- (void) onTimer {

    // Updates the variable h, adding 100 (put your own value here!)
    h += 100; 

    //This makes the scrollView scroll to the desired position  
    yourScrollView.contentOffset = CGPointMake(0, h);  

}
