iOS UIView类扩展，直接访问属性 —— HERO博客

iOS工程实用技巧，自定义UIView类扩展，直接访问width、height等属性。下面贴上代码：

#import <UIKit/UIKit.h>

@interface UIView (Extension)

@property (assign, nonatomic) CGFloat x;
@property (assign, nonatomic) CGFloat y;
@property (assign, nonatomic) CGFloat width;
@property (assign, nonatomic) CGFloat height;
@property (assign, nonatomic) CGSize size;
@property (assign, nonatomic) CGPoint origin;

@end

#import "UIView+Extension.h"

@implementation UIView (Extension)

- (void)setX:(CGFloat)x
{
CGRect frame = self.frame;
frame.origin.x = x;
self.frame = frame;
}

- (CGFloat)x
{
return self.frame.origin.x;
}

- (void)setY:(CGFloat)y
{
CGRect frame = self.frame;
frame.origin.y = y;
self.frame = frame;
}

- (CGFloat)y
{
return self.frame.origin.y;
}

- (void)setWidth:(CGFloat)width
{
CGRect frame = self.frame;
frame.size.width = width;
self.frame = frame;
}

- (CGFloat)width
{
return self.frame.size.width;
}

- (void)setHeight:(CGFloat)height
{
CGRect frame = self.frame;
frame.size.height = height;
self.frame = frame;
}

- (CGFloat)height
{
return self.frame.size.height;
}

- (void)setSize:(CGSize)size
{
CGRect frame = self.frame;
frame.size = size;
self.frame = frame;
}

- (CGSize)size
{
return self.frame.size;
}

- (void)setOrigin:(CGPoint)origin
{
CGRect frame = self.frame;
frame.origin = origin;
self.frame = frame;
}

- (CGPoint)origin
{
return self.frame.origin;
}

@end
