I'm trying to save an NSMutableArray called queueArray so it can be loaded again after the app has been quit. I used a few tutorials to get me going and this is the code I have come up with. The problem seems to be that "initWithCoder" and "encodeWithCoder" are not being called, shown by no NSLog calls and no stopping at breakpoints. ...

I made a tab bar application that has only one xib file. If you have have made tab bar applications before then you probably know what I did so I don't really have to explain it. I deleted the two xib files and used MainWindow.xib. I just added views to each tab bar button and assigned view controllers to each of them. So now I have a t...
Let's say I am designing an iPad app that presents user a screen. The screen contains several "controls" that for the sake of this example can be simple labels with +/- signs that increment/decrement integer value presented by the label, making sure that the value doesnt exceed max number defined for each control (numerical up/down contr...
I made a tab bar application with several tab bar buttons. Each button is linked to a separate xib file. This works for a xib with a UIViewController and a xib with a UITableViewController. However, it does not work for a xib with a UINavigationController. On the left you can see what it looks like in Interface Builder, and on the right...
All, This is one that should be simple, but since I'm rather new to the xcode IOS 4 developement, I gotta ask: What I need: an Image View with a button that will then display a series of linked table views. This screams (to me) a UINavigationController where the first view is NOT a table view, but the UIImage view. I cannot get this...
Update 2: Apple responded to my bug report with "We believe this issue has been addressed in iOS 4.2 b1 (8C5091e). Please let us know whether or not you continue to experience this issue with the newly released software by updating this bug report." I guess this acknowledges that the issue is in their code, not mine. I'll update with res...

Hi I was trying to use IB in a slightly different way that I am use to and I can't get it working extending the normal approach I use, when dealing with IB. Instead of making a new UIViewController and have the view XIB generated for me and everything linked together by Xcode, I would like to just build a small (320x40px) View XIB and ...
In my subclass of NSObject I would like to call something like [[self navController] presentModalViewController:myView animated:YES]; But none of my tries were successful. How can I call a modal view if I'm not in a subclass of UIViewController? Solution: #import "myProjectNameAppDelegate.h" // ... MyViewController *myView = [[M...
Hello all, I'm already pretty sure that it can't be done with any public API, but I still want to ask: Is there any way to change the line height in a UITextView? Would be enough to do it statically, no need to change it at runtime. The problem is that the default line height is just WAY too small. Text will look extremely compressed ...
I want to create a simple "control" that will have 4 UILabels defined in it. On one hand I'd like to use Interface Builder to layout my design but on the other hand i'd like to expose some properties that will define contents of each label - is it possible? @interface CompositeView : UIView{ int numberOne; int numberTwo; } @property(n...
