Maybe the most useful Obj-c category I ever made...

UIView+QuickSize

@interface UIView (QuickSize)

- (CGFloat)width;
- (CGFloat)height;
- (CGFloat)x;
- (CGFloat)y;

@end

@implementation UIView (QuickSize)

- (CGFloat)width
{
    return self.frame.size.width;
}

- (CGFloat)height
{
    return self.frame.size.height;
}

- (CGFloat)x
{
    return self.frame.origin.x;
}

- (CGFloat)y
{
    return self.frame.origin.y;
}
