Show loading screen while parsing, then refresh UITableView?
I have a UITableView with the following code: - (void)viewDidLoad { [super viewDidLoad]; parser = [[XMLParser alloc] init]; [parser parseXML]; My problem is that the launch takes too long because it's parsing everything before displaying the view controller with the UITableView. Also, if I set up another UITableView and pa...
How to make the "hot area" of a UIControl bigger?
Or: How to expand the sensitive area for a UIControl without just making the view bigger? I have a pretty small button image (a little arrow), which is just 10 x 10 pixels. Too small for touching. I want the "hot area" to be 50 x 50 around that. For learning, I want to know how to do it manually, even if I could use some of the provided...
How can a covered UIControl or UIView still know about if a touch ended over it or not?
I have a UIControl (or UIView, could have either of them, doesnt matter), and this is covered by another UIControl. The other UIControl reacts nicely on touches. But the underlying UIControl also needs to know about the touch and if the touch was actually "on it" or not (from the user's perspective). The covering UIControl is partially t...

I am using UITableViewCellStyleValue2 and UITableViewStyleGrouped.

Open view with slide effect from bottom to top on iPhone
Hi all! I'm making an application for iPhone (which runs in landscape mode) (OS 3.0), and I want that when I touch a toolbar button it opens a view with a slide effect (similar to the effect when you touch 'Bookmarks' in Mobile Safari's toolbar) from the bottom to the top of the screen.

Changing a UITableView's scroll insets programatically to reflect the size of an iPhone keyboard
I know you can use the "Inset" property in Interface Builder to make a scroll view be inset from the main window so that it doesn't go below existing controls on the screen such as a tab bar, but how can you do this programatically to adjust for when a keyboard is added to the screen? Currently my scroll view has cells under the keyboard...

How can a UIControl pass all touch events on to the next object in the responder chain?
That's tricky. I have a small button over a very big one. When the small button on that big button is pressed, the small button does something. But the big one does nothing. Of course. But now I want that the big button also does something, no matter if the small button was tapped or not. So the small button has to forward all touch even...
