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
//
//  Created by Ager on 15/10/18.

//

#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 = 300;
    //修改x坐标
    aview.x = 100;
    //修改y坐标
    aview.y = 100;
