Question

I have UIScrollView on which I am using 2 UIButtons. UIScrollView initial frame is (0,0,768,1024). I want when I click on first button the UIScrollView y-cordinate position will be 500, means it will scrolldown 500 positions below to its actual position.

And when I click second Button which Will show on UIScrollView, Position Y-cordinate of UIScrollView y=535, then UIScrollView Move up to Position y= 0 again.

First button click UIScrollView y = 500
Second button click UIScrollView y = 0

Any hints from experts would be very welcome.

Answer 1

This may solve ur pbm

-(IBAction) clickfirstbutton 
{
   [scrollview setContentOffset:CGPointMake(0, 500)) animated:TRUE];
}

-(IBAction) clicksecondbutton
{
   [scrollview setContentOffset:CGPointMake(0, 0) animated:TRUE];
}

If u don’t want animations use

[scrollview setContentOffset:CGPointMake(0, 0) animated:FALSE];
