I just discovered the NSRect helper functions in NSGeometry.h (i.e. NSMidX, NSMaxX, etc...)
These would have made some repetitive coding much easier. I knew about NSMak
This is a shortcut instead of a library call that I missed, but it is in the spirit of the thread.
One shortcut that I use alot is using an inline format statement in NSLog calls.
NSLog(@"x=%@", [someobject className]);
instead of the more verbose
NSLog([NSString stringWithFormat:@"x=%@", [someobject classname]]);
