I periodically am reproing a crash on a debug build running on my iPhone involving a UIScrollView with none of my code in the stack frame. I would like to know if it's a bug in my code or Apple's, and I am unable to query the Apple bug database to see if it has been reported. The backtrace shows: #0 0x30218060 in ___forwarding___ () #1...

The selector I've assigned to it never triggers, nor does the UIControlStateHighlighted image ever appear when tapping on the image. Is there something intercepting touches before they get to the UIButton, or is its interactivity...

My application has a UIScrollView with one subview. The subview is an extended UIView which prints a PDF page to itself using layers in the drawLayer event. Zooming using the built in pinching works great. setZoomScale also works as expected. I have been struggling with the zoomToRect function. I found an example online which makes a C...
Hi I am using a UIImageview inside a UIScrollView to let users pinch and zoom the image. I now want to get the image which the user has modified (small or zoomed in). How can I do this? Thanks.

I would like to update the view based on the position while it's scrolling. The best lead I've had has been this ( http://github.com/andreyvit/Scrolli...

I have setup a UIScrollView which handles a large UIView, inside the UIView is a UIImageView, I've managed to get the UITouch to drag the UIImageView outside of the UIScrollView but inside it's not registering the event. I ...
I am designing an app which will present large amounts of text that is interspersed with notes and references as clickable images. On a PC I'd use a control that shows HTML, but in the iPhone I am not able to intercept the touches of images and links too well using the UIWeb control. Should I use a UIScroll and build the text as lables ...
