I am a little confused about retain/release count when a local variable is allocated within a method, then returned to its caller. For example -(NSMutableString*)foo { NSMutableString *str = [[[NSMutableString alloc] init] autorelease]; [str appendString:@"Just a test"]; return str; } NSMutableString *myString = [self foo]; ...

I have a UISearchBar below a header-view. This header is 64px hight. If the searchbar gets touched, the parent view will move 64px up — fine. After finishing searching the parent view will only move down, as long there is still free space below it. And the top is out of the visible bounds. But I want to move it back to the original pos...
I'm getting into iPhone app development, but I have neither the money for a mac mini, nor a PC with hackintosh compatible specs. However, my university has some mac labs that I can access, but to which I cannot install new software. As such, I'm wondering if there is a way to run the iPhone SDK from a usb drive, so that I can start pra...
I have an sqlite table that shows scores from different game modes. In one of the columns, I don't want the score to show up unless the user reaches the final 5th level, but I also don't want it to be recorded as a 0 either. I want it to be as if the game was never played. No score recorded at all. Here's what I have.... if(appDeleg...

Hello, I would like to do pretty much what the Mail Application does: that when I select Edit, instead of the usual Delete Button, Radio Buttons appear on the side that may be checked by the user, then the user may click on a Button to take an action on the marked cells(any kind of action not just delete). Is there any apple sample code...

The resulting hierarchy should be: - View - Navigation Bar - Navigation Item (Title) - Bar Button Item - Bar Buttom Item I can never seem to add the second Bar Button Item. I know...
I've looked hard and have been unable to find good websites that have aggregated custom controls that have been submitted by users to be shared with everyone. Does such a repository exist? I would hope something like this existed considering that iPhone developers seem to be using similar custom controls. In particular, I'm trying to d...

The table starts out empty and the user can add new entities to it using the UI. As it stands, the program always works when adding the first entity, and always crashes when adding a second. There is sometimes no...

Can you set up a constant time update rate for CLLocationManager to force it update locations like every 10 seconds continuously? I know the usage of the distance filter but what if something went wrong and the location is not updated? Thanks! ...
I've been using the standard method to embed a Youtube video in a UIWebview as a thumbnail to give the appearance of playing the video in the iPhone app. But many times the video either gives a broken play button or returns after 1 minute or so that the video could not be played. I assume this is because the poster either didn't ma...
