In iTunes, you will see that the first two columns (the first narrow one containing nothing) and the second one containing song name, are not movable. The others are movable. How can I accomplish this with an NSTableView? ...
This has been driving me nuts all day. I have a weird bug that I think I have narrowed down to an NSPredicate. I have two entities: List and Person. List has a to-many relationship to Person called persons and Person has a to-many relationship to List called lists. I pass to my a tableview controller a List object. I then want that tab...

Ok, so I have an NSTextField and an NSSlider. In interface builder, I got the float value from the NSSlider to go into the NSTextField. BUT, I need a button that sends the text from the text field in so I can get the value in my code. That text field can also accept manual input so I cannot just link the NSSlider to my code. This is simi...

Hi all, Cocoa, Mac OS X 10.6. My app (a game) needs to determine if the mouse is down within a view, repeatedly, even if the mouse position doesn't change. The problem: mouseDown will only be called the first time the mouse is pressed and held down. If the mouse is not moved at this point, mouseDragged is not called, and no more mou...
When I press enter on an NSTextField to send what ever's in the text field, it sends it, but highlights what ever's in the NSTextField. Does anyone know how to make it so that once it sends the command in, it deletes what ever's in the NSTextField? Thanks, Elijah ...

Update : found the solution. I will update this question soon with the actual working code and command. A client is encrypting a file server-side with C++, and I need to decrypt it in an iPhone application.

I have a situation where I need to use some strings temporarily but I've read so many conflicting things that I'm a bit confused as to what the best way to proceed is. I need to assign some strings inside an if structure but use them outside the if structure so they need to be created outside the if, I was thinking something like: NSSt...

Could someone tell me what exactly NSCFTimer is? I get it when I ask NSTimer for a timer. My problem is that I'm trying to check if an object (supposedly an NSTimer, note the word "supposedly" which is why I'm checking) is an object of class NSTimer, it doesn't seem to work. Does this "NSCFTimer" in any way... hinder the process? ...
