My edit button is placed in viewDidLoad: self.navigationItem.rightBarButtonItem = self.editButtonItem; It shows up correctly on the nav bar, and tapping this button indeed change it to Done. However, no minus buttons show up in my table rows. Swiping a row, then tap Delete works, though. Any ideas? EDIT 1: Here's how I'm doing: - (...
I am trying to develop an application which is geo-sensetive. So, I have written - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { // Return YES for supported orientations // return (interfaceOrientation == UIInterfaceOrientationPortrait); return YES; } I have put different imag...
The documentation doesn't say anything about that. When an old object is "removed" and a new one comes into it's place, then what happens with the old one? Do I have to release it by myself? ...
I've used instruments for searching for memory leaks. I did that through XCode Run > Start with performance tool > Leaks. Then I quit Instruments. And every time I Build&Go, Instruments automatically launches. Although that's cool, when just wanting to test the app, it's not needed. How can I turn that off? ...
I have 12 views which I rotate almost similar to the icons in the home screen when going into homescreen-customization-mode by touching an icon for a few seconds. I use a 3D transformation code to do the rotations. They have each a duration of just 0.02 seconds, and the angle and direction of rotation changes permanently upon accelerati...

I have a UITableview that I would like to scroll to the top when the status bar is touched. I expected to find a notification that I could listen to and then use tableview:scrollToRowAtIndexPath: for the scroll, but can find none. Is there a way to do this? [Update] Finding some more on the net, I am suspicious that this is the simu...
The iPhone platform has a number of common gesture idioms. For example, there are taps, pinches, and swipes, each with varying number of fingers. But when you're developing an app, it's up to you to implement these things based on low-level information about the number and locations of touches. It seems like this is a prime candidate ...
I have an UIScrollView that contains some UIImageViews which are animated. It really only looks cool if there's a minimum scrolling speed happening. But when the user slowly scrolls and lifts the finger, the UIScrollView decelerates very slowly. The problem is, that the scrollViewDidScroll method doesn't get called upon every offset cha...

I've choosen the "view-based" application template in Xcode. The myProjectViewController.m has the following code: /* // Implement loadView to create a view hierarchy programmatically, without using a nib. - (void)loadView { } */ That sounds good. But: The template generated a myProjectViewController.xib file. What I dont get is: How ...
I have a program which automatically launches a phone call when program is started. This is implemented in AppDelegate's "applicationDidFinishLaunching"-method. Problem is: When phone call ends and my app automatically launches again, it restarts that loop and phone call is started again. How to recognize if app was returned from that ...
I haven't tried that yet, but I assume that I would have to disable scrolling of the parent scroll view as soon as I know that the user will want to scroll in the child scroll view, right? Both scroll views are scrolling horizontal. How could I disable scrolling detection of the parent temporarily? Or is there some other way? ...
