As far as I can see (correct me if I'm wrong), there seems to be no obvious way to have a scrolling page of styled text (diff fonts, weight, sizes, colors etc of text) on the iPhone without resorting to a UIWebView, which seems to take quite a bit of memory and resources (and the scrolling isn't as smooth as a UITableView). Is there a g...
Using the Apple's PageControl sample code I've managed to put several UIWebViews side-by-side, and I'm able to swipe left and right in order to get to each web view. I can also scroll up/down to scroll within each web view. However, I have to move my finger very precisely along the y-axis to get the webview to scroll up/down - otherwise...

In my app I have some logic that changes the UIScrollView's contentSize dynamically. The problem I'm running into is that when I change the contentSize it sets the contentOffset to CGPointZero or something like that. I guess you can't set contentSize to be in the middle of the UIScrollView. Any ideas on how to get this to work? In othe...

I have a UIView with three UIScrollViews. I load each with custom UIImageViews that already have their images assigned. The custom UIImageViews are simple and only introduce a few new properties that allow for tracking the imageviews within the scrollviews. Images load from disk very fast. The code below executes very fast but I have...
I have a multi-line UILabel that I want to enable zooming on. I embedded it with a UIScrollView and set min zoom to .25 and max zoom to 4.

In my app I have a view that extends UIScrollView and populates its content as the user scrolls. However, if the user scrolls too fast the views being populated inside the UIScrollView don't get created on time and you can actually see the UIScrollView's background. The reason why this happens is because I'm doing this lazy loading in th...
