After I connect my iPad to an external screen, my window gets distorted all weirdly. I'm guessing this is because the screen's resolution is different than the iPad's and my app is not setup to autoresize it's views very well. Is there anyway to have the rendered output on the external screen be a a scaled visual image of the original i...
I was expecting this to work, only thinking it would fail if I had locally declared another variable called "tableView" NSLog(@"X: %@", [tableView delegate]); // Fails: tableView undeclared . NSLog(@"X: %@", [[self tableView] delegate]); // Works: Is this because you need self to refer to items on the actual object? NB: this code ...

In Core Data is there a way to have one instance of an object to have multiple links to another? This is best understood with an example. You have a shopping cart object, ShoppingCart, and you have books, Book. How do you properly put multiple copies of the same book into the cart? No matter how many times you run [shoppingCart addBooks...
Hi everyone, i'm making a simple iPhone game using cocos2d-iphone. I have an array of fiends, the "fiendSet" which has to navigate around a field full of obstacles.

I've included the function that is handling all of the save functionality. Here's my problem. I am grabbing 5 input values and saving it as a CoreData Log Entity. Even when the Log object fails to validate, it is still being saved when I back out of the form and look at the table view. How can I force Core Data to only save the ob...
Disclaimer: Cocoa newbie here. I wrote an app with a Cocoa GUI that acts as a wrapper for a command line tool. The problem is the tool does not come standard with OS X. Thus, you have to install the command line tool first before using the Cocoa app, or else the app won't function. Can anyone point me to some documentation (hopefu...

I have an animation as my image in one of my tableview's cells. When it is clicked, it turns the default blue and the image disappears! The navigation loads the new view, and when it I go back to the first view, hoping my animation returns, alas, there is no image :(.

New to iPhone dev. I have a view which contains a UIScrollView which contains a UIImageView. I added a (double) tap gesture recognizer on the image view which makes an alert box open. For some reason, and I'm sure I'm just retarded, it opens 3 times. Here's my code: - (void)viewDidLoad { scrollView.delegate = self; UIImage* i...
I have an NSTextField which uses as an extended NSTextFieldCell, which creates a custom field editor, that intercepts and records key events.
