My first try was to use a...

I don't use IB much for creating my views, so I usually do everything programatically. I'm bascially pushing a viewController to a navigation controller and it seems the top part of the viewController is under the navigation bar. I'm trying to make the view fit correctly. Here is my code: navigationController = [[UINavigationControlle...

What am I doing wrong? Should I be using a completely different method, or is there some way I can modify my code to add the geo-tag and other...
I'm pushing a tableview in a navigation based app. The pushing view (viewOld) and pushed view (viewNew) are both UITableViewControllers. I have given viewNew a title from viewOld. Once viewNew appears, I see the title but no back button on the left. Shouldn't a back button appear once you give the view (viewNew) its title? I can click...
Hi Folks, I've got an NSMutableArray that holds a bunch of objects, what I'm trying to figure out is how much memory is the array using. After looking at a couple of places I know about the sizeof call, and when I make it I get 32 bits (which is the size of the NSMutableArray object it self). Example code: NSMutableArray *temp = [[NSM...

Hi, how would you go about saving a state in a tableview-drilldown, when using core data? So next time you start the app, the drill down level you where at when you exit the app will be loaded in. I looked at apples drilldownsave sample code, but couldn't figure our how to change to code to work with core data. Any help would be ve...

I have a parent UIView with a number of subviews. Periodically I need to remove a subview and completely remove it from the system. What is the correct way to do this? I tried this: UIView *v = [self.containerView viewWithTag:[n integerValue]]; [v removeFromSuperview]; And got bizarre result. Previously present UIViews dissap...
I am doing a scientific visualization app for iPhone. Periodically a UIView subclass will receive some data from the network that it must render via its overridden drawRect: method. My challenge is that there is no way to indicate to Cocoa-Touch that this data has arrived - or changed - other then [myView setNeedsDisplay] which is ignor...

I have a subclass of a UILabel that overloads initWithCoder and I was wondering if anyone has any documentation on how the coder is encoded so that I might be able to get information that comes from IB myself. Thanks. EDIT Reason for doing this: I would like the font name given in the xib file. Apple's implementation of initWithCoder ...
