UISCrollView Help!!

Hello,

I have two subviews that are implemented into my scrollview so that I can scroll between the two of them... On my second view I have a textfield, I need to be able to close the keyboard that belongs to that textField when the tableView slides to the other view. How can I do this? (I would like for it to look similar to spotlight on iOS)

to close a keyboard

Code:

[txtField resignFirstResponder];

to know where are you during the scroll of scrollview.

Code:

- (void)scrollViewDidScroll:(UIScrollView *)sender {
	
	int page = floor((scrollView.contentOffset.x - pageWidth / 2) / pageWidth) + 1;
        NSLog(@"page:%d",page);
}

where pageWidth is your view width (assuming that both have the same width)

so if page = 1 you are on first subview, else you are on second subview.

Create a int that contain currentPage, and when it change to 1, resignFirstResponder your textField.

Thanks! It works perfectly!

I knew how to close the keyboard I just couldn't find a way to track where the scrollView was in it's scrolling.

Thanks again!
