IOS Add View categories (more convenient to set the view location)

Click Create UIView category, which is named Plextension (to correspond to the following)

View category. h file

#import <UIKit/UIKit.h>@interface  UIView (plextension) @property (nonatomic, assign) CGFloat wl_width; @property (nonatomic, assign) CGFloat wl_height; @property (nonatomic, assign) CGFloat wl_x; @property ( Nonatomic, assign) CGFloat wl_y; @property (nonatomic, assign) CGFloat Wl_centerx; @property (nonatomic, assign) CGFloat WL _centery; @property (nonatomic, assign) CGFloat wl_right; @property (nonatomic, assign) cgfloat Wl_bottom; @end
