iOS-UIView一些坐标和位置方法封装

新建基于UIView扩展类 UIView+wkjFrame，此类是为了方便获取一些基于UIView类UI控件的坐标和位置的简化，直接引用即可

UIView+wkjFrame.h

- (CGPoint)origin;
- (void)setOrigin:(CGPoint) point;

- (CGSize)size;
- (void)setSize:(CGSize) size;

- (CGFloat)x;
- (void)setX:(CGFloat)x;

- (CGFloat)y;
- (void)setY:(CGFloat)y;

- (CGFloat)height;
- (void)setHeight:(CGFloat)height;

- (CGFloat)width;
- (void)setWidth:(CGFloat)width;

- (CGFloat)tail;
- (void)setTail:(CGFloat)tail;

- (CGFloat)bottom;
- (void)setBottom:(CGFloat)bottom;

- (CGFloat)right;
- (void)setRight:(CGFloat)right;

UIView+wkjFrame.m
