I've got a UIScrollView covered with a custom UIView which desperatly needs to listen to all the touch events that happen inside of him. At first, all I was getting was touchesBegan: and touchesCancelled: events. No touchesMoved:, no touchesEnded:. In fact, all the dragging gestures where being canceled by the above UIScrollView. This w...

Basically... I have a UIScrollView subclass which you can add a target and selector too, which get fired if a touch event is detected within the view. I am using the scroll view as an image gallery, and the touch inside the scroll view is used to fade out the HUD components (UItoolBar, etc): @implementation TouchableScrollView - (voi...
Look at the App Store app, on either the iPhone or the iPad, specifically the piece on the screen of app details that shows screenshots. The screenshot viewer shows you the screenshot you're looking at, and the edges of the next and previous one. I need to implement something much like that. How I've done it is fair to poor: I built a U...

hello all, I have a scrollview with lets say ten subviews in it. All are shown at the same time. I want to page between each subview. One idea is to set the frame size equal to a single subview and turn the paging on. But then it will receive the touch only within that frame. I want the user should be able to scroll it from any where i...

I'm trying to improve the performance of my image-intensive iPhone app by using a disk-based image cache instead of going over the network. I've modeled my image cache after SDImageCache (http://github.com/rs/SDWebImage/blob/master/SDImageCache.m), and is pretty much the same but without asynchronous cache in/out operations. I have some...

Using the PhotoScroller example from Apple, to reuse the memory allocated for views, I cannot get the memory released once the retain count hits 0. Here my code for a better understanding: This piece is an extract from PhotoScroller PhotoViewController.m - (void)configurePage:(ImageScrollView *)page forIndex:(NSUInteger)index { ...
I have a view which contains a UISearchBar. This UISearchBar is not displayed at the top of the page - it is about 90 pts down from the top of the screen, under a header image. All elements of the view are wrapped in a UIScrollView. The right thing happens when the user taps in the UISearchBar - the entire view is scrolled up so the sea...
