当需要调整视图的frame中的一个属性时，对UIViews进行处理是非常繁琐的。

你有多少次做过类似如下操作？

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

这段代码不仅难以编写，也不易于阅读和维护。如果我们能够简单地完成类似以下操作，那该多好？

view.frameMinX += 50.0;

或者如何将视图固定在其父视图的右上角

view.frameTopRight = view.superview.boundsTopRight;

frame操作

以下是为frame操作添加的以下属性

• @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;

还有一些实用方法帮助操作frames
注意，任何调整方法都会取当前值并将给定的调整量+等于得到的调整值

• - (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;

一些额外的用于调整frame对齐的功能！

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

frame填充与扩展

填充和扩展frames也非常繁杂，所以我们有一些快速的帮助函数来完成此操作！

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

调整frame大小

在iOS中，自动调整大小很棒，但有时你只想允许宽度或高度进行调整。

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

边界

处理边界不太烦人，但有时一些快速助手可以使代码更容易、更快，但这些属性是只读的。

• @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;
