看到一些程序都有这种写法,也不知道原创者是谁了。先在博客保存下。
在.m文件
#import "UIView+MyFrameCategory.h" @implementation UIView (MyFrameCategory) //================================= - (void)setX:(CGFloat)x; { CGRect tempFrame = self.frame; tempFrame.origin.x = x; self.frame = tempFrame; } - (CGFloat)x; { return self.frame.origin.x; } //================================= - (void)setY:(CGFloat)y; { CGRect tempFrame = self.frame; tempFrame.origin.y = y; self.frame = tempFrame; } - (CGFloat)y; { return self.frame.origin.y; } //================================= - (void)setWidth:(CGFloat)width; { CGRect tempFrame = self.frame; tempFrame.size.width = width; self.frame = tempFrame; } - (CGFloat)width; { return self.frame.size.width; } //================================= - (void)setHeight:(CGFloat)height; { CGRect tempFrame = self.frame; tempFrame.size.height = height; self.frame = tempFrame; } - (CGFloat)height; { return self.frame.size.height; } //================================= - (void)setSize:(CGSize)size; { CGRect tempFrame = self.frame; tempFrame.size = size; self.frame = tempFrame; } - (CGSize)size; { return self.frame.size; } //================================= - (void)setCenterX:(CGFloat)x; { CGPoint tempPoint = self.center; tempPoint.x = x; self.center = tempPoint; } - (CGFloat)centerX; { return self.center.x; } //================================= - (void)setCenterY:(CGFloat)y; { CGPoint tempPoint = self.center; tempPoint.y = y; self.center = tempPoint; } - (CGFloat)centerY; { return self.center.y; } //================================= @end
在.h文件
