I've got a UITableView that's loading a bunch of RSS feeds, and the favicon for each feed is shown in the table cell. It works well most of the time, but sometimes the image does not appear.

The problem is that when I scroll the table, the app's memory consumption always increases up to the point where the app crashes due to low memory conditions. The t...
I've written an application for the iPad that I'd now like to get working on the iPhone (a universal application). At the moment it runs in the iPhone simulator, but the UIKit elements are positioned using pixel positions - so a lot of them are offscreen. Additionally my UIImages are too big, and need to be scaled to fit the iPhone. How...
