Small library with a few helpers that I use daily to save up some code.

example:

instead of:

CGRect frame = view.frame;
frame.size.width -= 20;
view.frame = frame;

you can write:

view.frame.width -= 20;

Categories provided

• UIImage.width and UIImage.height
• UIView:
  • CGFloat x
  • CGFloat y
  • CGFloat width
  • CGFloat height
  • CGFloat boundsX
  • CGFloat boundsY
  • CGFloat boundsWidth
  • CGFloat boundsHeight
  • CGPoint origin
  • CGPoint boundsOrigin
  • CGSize size
  • CGSize boundsSize
• UIButton
  • UIImage *image
  • UIImage *backgroundImage
  • UIImage *selectedImage
  • UIImage *selectedBackgroundImage
  • NSString *title
  • NSString *selectedTitle

Other helpers:

• Device helpers

BOOL IsRetinaScreen();
BOOL IsRetina4Screen();
CGFloat iOSVersion();
BOOL iOSVersionIsAtLeast(CGFloat version);
BOOL iOSVersionIsAtMost(CGFloat version);
BOOL iOSVersionIsGreatherThan(CGFloat version);
BOOL iOSVersionIsLessThan(CGFloat version);

• Notification helpers (I tried to make notifications as easy and flexible as possible, so there are a lot of optional parameters)

  On(NSString *event[, id object], NotificationBlock block);
  On(NSString *event[, id object], id target, NSString *selectorName);

  Off(NSString *event[, NotificationBlock block]);
  Off(NSString *event[, id target, NSString *selectorName]);

  Trigger([id sender,] NSString *event [, NSDictionary *userInfo]);

  • Clarifying notification parameters: The second On method could be originally written as:

  [[NSNotificationCenter defaultCenter] addObserver:target
                                        selector:NSSelectorFromString(selectorName)
                                        name:event
                                        object:object];

  Alternatively you may substitute the target and selector for a block...
