I'm using a CATiledLayer for the visualisation of data. By default the drawLayer function gets a transposed and scaled context, which allow the drawing code to be agnostic of the zoom-level and the tile that's being requested. However, I would like to use the zoom functionality to change the horizontal range of the data, without actual z...
I have a UIScrollView that is scrolling a fairly large UIView. At certain times I want to limit the area the user can scroll around in. For example, I may only want to allow them to view the bottom quarter of the view. I am able to limit the area by overriding scrollViewDidScroll and then calling setContentOffset if the view has scrol...

Hi Guys, I've got a UIScrollView filled with images, one of the images is animated (i.e. has 45 frames repeating within it as 45 separate images).

Hi everyone: I have many ImageViews set with OnClickListeners. They extend beyond the screen, contained in a ScrollView. When scrolling down and clicking an ImageView that was previously beyond the screen, onClick(View view) does not seem to execute until the second click. It behaves normally otherwise. My Activity implements OnClickLi...
Hi Guys, I have an image that is 320x480 and upon orientation change this image obviously hangs out of view. There are some images where the focal point of it sits with it's bottom cut off (which isn't undesirable). My issue however is when the user pans vertically to see the full image, the view appears to snap to the bottom meaning th...
This should be straight foreward, but I simply can't figure it out(!) I have a UIView 'filled with' a UIScrollView. Inside the scrollView I wan't to have a UITableView.

For an iPhone app, I'm going to need to display read-only tabular data in a grid format. This data could potentially have many rows and columns. I could use UITableView, but the problem is the data will most likely be very wide and require scrolling. Is there a way to put a UITableView in a UIScrollView and allow zooming and scolling ...
I need to closely monitor the scale of the scroll view so that I can update the content view's elements (a subview managing multiple CALayers) according to the scroll view's animated zoom. On iOS 3.1, overything works as expected, I use zoomToRect:animated: and the scrollViewDidScroll: message of the UIScrollViewDelegate gets called rep...
Hi guys, I've developed a jQTouch app ( http://bit.ly/9uE1i0 ), with iScroll integration ( http://bit.ly/9KsKz3 ), using the native tabbar ( http://bit.ly/ag3H6b ).

I'm working on an an app that updates both a UITableView and a UIScrollView. I like how UITableView updating works. As I add, remove, or update items, I call insertRowsAtIndexPaths:withRowAnimation:, reloadRowsAtIndexPaths:withRowAnimation:, and deleteRowsAtIndexPaths:withRowAnimation: as appropriate. However, updating the UIScrollView h...
