View attached to UIScrollView not receiving touches events

[TheFury]

I have MyView attached to a scroll view. MyView implements touchesBegan and touchesEnded. When it first comes up and I press and hold inside the view, I do NOT get touchesBegan. If, however, I press and drag to scroll the view, then press and hold inside the view, I DO get touchesBegan.

I don't expect to get a touchesBegan immediately since the scroll view is handling the scrolling aspect; but when I press and hold, I should get the event after a short delay. As I said, if I manually scroll the view before performing the press and hold, everything works as expected.

I see nothing in the UIScrollViewDelegate that could help. I see the touchesShouldBegin member of the UIScrollView interface; but the docs say the default return is YES. So I don't see how that's going to help me either.

Any suggestions?

BTW, if MyView is small enough that the contents does not require scrolling, touchesBegan is called as expected.

I got something working. FYI, I just derived from UIScrollView and handle the touchesBegan in that class.

Hi,

i am also doing same kind of app. When i put scrollView.userInteractionEnabled=NO; i am getting touchBegin, touchMoved and touchEnded working fine. But when scroll is not working.

What i am trying to do is, when i single tap on scrollview, i am hiding nav bar and tool bar(below) and when i double tap showing nav bar and tool bar.

Could you post, you code or send sample application.

Hi,

In developer.apple.com's sample codes, i have found one sample code "Scrollview suite" follow it you will get a solution. I am using that only.

Now my problem is solved.

// this piece of code discards the keyboard from a text view or from a text field with keyboard type numberpad or that sort(with no return key)

UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleSingleTap];
[scrollView addGestureRecognizer: singleTap];

==

- (void) handleSingleTapid*) sender
{
NSLog(@"gesture rec picked up event");
if([textField isFirstResponder])
{
[textField resignFirstResponder];
}
}


cheers!
