Hello all, I have an instance of a FlowCoverView (a great library that emulates cover flow on the iPhone). And it works great, with the exception of an update. When I update my table behind the scenes, I have no way of telling this control (that is defined in IB) that it has been updated, and to reload. (much like you can with a tabl...

Hi all. Can anyone give a definitive explanation on the relationship between UIView's setNeedsLayout, layoutIfNeeded and layoutSubviews methods? And an example implementation where all three would be used. Thanks. What gets me confused is that if I send my custom view a setNeedsLayout message the very next thing it invokes after this me...
How do you use Objective-C (iPhone) to send an AppleScript to a remote computer (on same network) to be executed? I think something like NSNetService would be of use here, but I don't know. EDIT: Ok, to clarify, all I want to do is send a command ID or something and then the Computer associate that with the corresponding AppleScript co...

I'm a web developer and I'm getting envious of all the cool iPhone apps. I know nothing about C or what ever language they use to make iPhone apps. I really have no idea where to start. What do I need to do? Should I take a class, buy a book? I have a pretty good grasp on programing, I do tons of HTML, CSS and Javascript development and ...

If your script executes for more than 10 seconds, Safari on iPhone OS stops executing the script at a random place I plan to have some Javascript run every 10 seconds or so that will do an AJAX query to the...
Hey, I would like to know how you can disable UIActionSheets, specifically the Action Sheets being displayed after tapping and holding hyperlinks in a UIWebView. These seem to be enabled by default in UIWebViews containing the link address of the respective link in the title of the alert. They are also enabled in Safari. (How) is it po...
