I know I've got the outlets connected properly in IB for WidgetTVC, I know that image data is being properly returned from my server, and I've alloc/init'd the widget.logo UIImage too. Why is th...
I am used to programming for the iPhone. There, I would connect a button to an action, and then a method by creating the method like so: -(IBAction) DoStuff{…}. Then I would make an outlet for the button, and then the actual button in Interface Builder. I would then connect the button to the outlet, and then connect the button to the act...
I downloaded xcode 3.2 and the iphone sdk 4.1, which has been working wonderfully, until a few days ago. For some reason whenever I open interface builder by clicking on a xib file all the pictures in the buttons and imageviews display a big blue question mark, and then interface builder gives me this: Assertion Message: An uncaught exc...
I have a table view that displays dates using a NSDateFormatter to format them using the Full date style (today would be formatted as "Friday, September 24, 2010" or in German "Freitag, 24. September 2010"). But when editing the date the formatter forces the user to type the date in the same format. How can I make the formatter accept da...

I have an NSTableView connected to an NSArrayController by setting the column values in interface builder to the appropriate keys in the NSArrayController.

Let me explain: This is my UI: I want my menu items to automatically adjust to singular or plural based on the number in the text field. For example, when I type "1" in the box, I want the menu items to be l...

Something I'm not very clear on is whether I should/could use interface builder to create reusable game sprites. For example, if I have a ball that I want to create an indeterminate amount of at run time, should I be creating a nib file (and either attaching graphics in IB or drawing them in drawRect) with it's own viewcontroller class a...
