iOS UIView 快速修改 frame，

在iOS开发布局修改 frame 时需要繁琐的代码实现,今天偶尔看到一播客说到快速修改的 frame 的方法,自己动手写了一遍实现代码.

快速实现主要通过 添加类目的方式,对UIView 控件添加了一些直接修改 frame 属性的方法(如:获取高度.宽度,坐标等);具体代码实现如下:

.h文件,声明要用到的属性

 //
 //  UIView+Layout.h
 //  Layout
 //

 //

 #import <UIKit/UIKit.h>

 @interface UIView (Layout)

 //顶,底,左,右
 @property (nonatomic , assign)CGFloat top;
 @property (nonatomic , assign)CGFloat bottom;
 @property (nonatomic , assign)CGFloat left;
 @property (nonatomic , assign)CGFloat right;

 //坐标,x,y
 @property (nonatomic , assign)CGFloat x;
 @property (nonatomic , assign)CGFloat y;
 @property (nonatomic , assign)CGPoint origin;

 //中心点坐标 centerX,centerY
 @property (nonatomic , assign)CGFloat centerX;
 @property (nonatomic , assign)CGFloat centerY;

 //大小 ,宽,高
 @property (nonatomic , assign)CGFloat width;
 @property (nonatomic , assign)CGFloat height;
 @property (nonatomic , assign)CGSize size;

 @end

.m 文件实现对 属性 的操作.从而实现对 frame 的修改

 //
 //  UIView+Layout.m
 //  Layout

 #import "UIView+Layout.h"

 @implementation UIView (Layout)

 //顶,底,左,右
 //top;
 - (CGFloat)top{
     return self.frame.origin.y;
 }

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

 //bottom;
 - (CGFloat)bottom{
     return CGRectGetMaxY(self.frame);
 }

 - (void)setBottom:(CGFloat)bottom{
     CGRect frame = self.frame;
     frame.origin.y = [self bottom] - [self height];
     self.frame = frame;
 }

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

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

 //right;
 - (CGFloat)right{
     return CGRectGetMaxX(self.frame);
 }

 - (void)setRight:(CGFloat)right{
     CGRect frame = self.frame;
     frame.origin.x = [self right] - [self width];
     self.frame = frame;
 }

 //坐标,x,y
 //x;
 - (CGFloat)x{
     return self.frame.origin.x;
 }

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

 //y;

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

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

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

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

 //中心点坐标 centerX,centerY
 //centerX;
 - (CGFloat)centerX{
     return self.center.x;
 }

 - (void)setCenterX:(CGFloat)centerX{
     CGPoint center = self.center;
     center.x = centerX;
     self.center = center;
 }

 //centerY;
 - (CGFloat)centerY{
     return self.center.y;
 }

 - (void)setCenterY:(CGFloat)centerY{
     CGPoint center = self.center;
     center.y = centerY;
     self.center = center;
 }

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

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

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

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

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

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

 @end

应用举例:

     //修改宽
     aview.width = ;
     //修改x坐标
     aview.x = ;
     //修改y坐标
     aview.y = ;
