UIViews are particularly annoying to work with when having to adjust just one property of their frame.

How many times have you done something like:

CGRect r = view.frame;
r.origin.x += 50.0;
view.frame = r;

Not only is this code annoying to write it also is hard to read and maintain. Wouldn't it be awesome if we could just do something like:

view.frameMinX += 50.0;

Or how about pinning the view to the top right corner of its super view:

view.frameTopRight = view.superview.boundsTopRight;

Frame Manipulation

These are the following properties added for frame manipulation

• @property (nonatomic, assign) CGFloat frameMinX;
• @property (nonatomic, assign) CGFloat frameMidX;
• @property (nonatomic, assign) CGFloat frameMaxX;
• @property (nonatomic, assign) CGFloat frameMinY;
• @property (nonatomic, assign) CGFloat frameMidY;
• @property (nonatomic, assign) CGFloat frameMaxY;
• @property (nonatomic, assign) CGSize frameSize;
• @property (nonatomic, assign) CGFloat frameWidth;
• @property (nonatomic, assign) CGFloat frameHeight;
• @property (nonatomic, assign) CGPoint frameTopLeft;
• @property (nonatomic, assign) CGPoint frameTopCenter;
• @property (nonatomic, assign) CGPoint frameTopRight;
• @property (nonatomic, assign) CGPoint frameCenterLeft;
• @property (nonatomic, assign) CGPoint frameCenter;
• @property (nonatomic, assign) CGPoint frameCenterRight;
• @property (nonatomic, assign) CGPoint frameBottomLeft;
• @property (nonatomic, assign) CGPoint frameBottomCenter;
• @property (nonatomic, assign) CGPoint frameBottomRight;

There are also some handy methods to also help manipulate frames:
Note any adjust methods take the current value and += the given adjustment

• - (void)setFrameX:(CGFloat)x y:(CGFloat)y width:(CGFloat)width height:(CGFloat)height;
• - (void)adjustFrameX:(CGFloat)x y:(CGFloat)y width:(CGFloat)width height:(CGFloat)height;
• - (void)setFrameX:(CGFloat)x y:(CGFloat)y;
• - (void)adjustFrameX:(CGFloat)x y:(CGFloat)y;
• - (void)setFrameWidth:(CGFloat)width height:(CGFloat)height;
• - (void)adjustFrameWidth:(CGFloat)width height:(CGFloat)height;

Also some extras to point align your frames!

• - (void)adjustFrameToWholePointsByRounding;
• - (void)adjustFrameToWholePointsByFlooring;
• - (void)adjustFrameToWholePointsByCeiling;

Frame Insetting & Expanding

Insetting and expanding frames are also extremely annoying so we have some quick helpers to do that too!

• - (void)insetFrameBy:(CGFloat)amount;
• - (void)insetFrameByWidth:(CGFloat)widthAmount height:(CGFloat)heightAmount;
• - (void)expandFrameBy:(CGFloat)amount;
• - (void)expandFrameByWidth:(CGFloat)widthAmount height:(CGFloat)heightAmount;

Sizing Frames

Autosizing is great in iOS but sometimes you only want to width or height to be allowed to adjust.

• - (void)sizeWidthToFit;
• - (void)sizeHeightToFit;

Bounds

Dealing with the bounds is less annoying but sometimes some quick helpers make code easier and quicker but are readonly.

• @property (nonatomic, assign, readonly) CGFloat boundsMinX;
• @property (nonatomic, assign, readonly) CGFloat boundsMidX;
• @property (nonatomic, assign, readonly) CGFloat boundsMaxX;
• @property (nonatomic, assign, readonly) CGFloat boundsMinY;
• @property (nonatomic, assign, readonly) CGFloat boundsMidY;
• @property (nonatomic, assign, readonly) CGFloat boundsMaxY;
• @property (nonatomic, assign, readonly) CGSize boundsSize;
• @property (nonatomic, assign, readonly) CGFloat boundsWidth;
• @property (nonatomic, assign, readonly) CGFloat boundsHeight;
• @property (nonatomic, assign, readonly) CGPoint boundsTopLeft;
• @property (nonatomic, assign, readonly) CGPoint boundsTopCenter;
• @property (nonatomic, assign, readonly) CGPoint boundsTopRight;
• @property (nonatomic, assign, readonly) CGPoint boundsCenterLeft;
• @property (nonatomic, assign, readonly) CGPoint boundsCenter;
• @property (nonatomic, assign, readonly) CGPoint boundsCenterRight;
• @property (nonatomic, assign, readonly) CGPoint boundsBottomLeft;
• @property (nonatomic, assign, readonly) CGPoint boundsBottomCenter;
• @property (nonatomic, assign, readonly) CGPoint boundsBottomRight;
