简单的搞两个btn的效果

一般button 加文字是这样的

但是有时候我们想要文字和图片搁一边的如图

这样改遍图文布局就行
上代码

#import "MyButton.h"

@implementation MyButton

-(CGRect)titleRectForContentRect:(CGRect)contentRect

{//上下
    
//    CGFloat titleY = contentRect.size.height *0.6;
//    
//    CGFloat titleW = contentRect.size.width;
//    
//    CGFloat titleH = contentRect.size.height - titleY;
    //左右
       CGFloat titleY = 0;
    
        CGFloat titleW = contentRect.size.width*0.5;
    
        CGFloat titleH = contentRect.size.height;
//不规则
//    CGFloat titleY = 0;
//    
//    CGFloat titleW = contentRect.size.width;
//    
//    CGFloat titleH = contentRect.size.height;
    return CGRectMake(0, titleY, titleW, titleH);
    }


-(CGRect)imageRectForContentRect:(CGRect)contentRect

{
    //上下
  //  CGFloat imageW = CGRectGetWidth(contentRect);
    
  //  CGFloat imageH = contentRect.size.height * 0.6;
    //左右
    CGFloat imageX = contentRect.size.width*0.5;
    CGFloat imageW = CGRectGetWidth(contentRect) * 0.5;
    CGFloat imageH = contentRect.size.height;
    //不规则
//    CGFloat imageX = contentRect.size.width*0.3;
//    CGFloat imageW = CGRectGetWidth(contentRect) * 0.4;
//    
//    CGFloat imageH = contentRect.size.height;
 
    
    return CGRectMake(imageX, 0, imageW, imageH);
    
}

@end

重写以上代码就可以实现 其中的位置自己修改就好

那么问题来了如果我想实现这正效果怎么办

btn 中间视图两边是文字怎么搞 很简单直接重写btn就好

#import 
//继承btn  的.h
@interface MyButton : UIButton
@property (nonatomic,strong)UILabel * firstLabel;
@property (nonatomic,strong)UILabel * secondLabel;
@property (nonatomic,strong)UIImageView * centerImage;
- (instancetype)initWithFrame:(CGRect)frame;
@end

//.m文件
- (instancetype)initWithFrame:(CGRect)frame{
    if (self = [super initWithFrame:frame]) {
        UILabel * lalbl = [[UILabel alloc]initWithFrame:CGRectMake(0, 0, 20, frame.size.height)];
        self.firstLabel = lalbl;
             [self addSubview:lalbl];
        UIImageView * imagebtn = [[UIImageView alloc]initWithFrame:CGRectMake(CGRectGetMaxX(lalbl.frame), 0, frame.size.width - 40, frame.size.height)];
        self.centerImage = imagebtn;
     
        [self addSubview:imagebtn];
        UILabel * lalbl2 = [[UILabel alloc]initWithFrame:CGRectMake(CGRectGetMaxX(imagebtn.frame), 0, 20, frame.size.height)];
      
        self.secondLabel = lalbl2;
        [self addSubview:lalbl2];
    }
    return self;
}

那么如何调用呢

 MyButton * mybtn = [[MyButton alloc]initWithFrame:CGRectMake(200, 200, 100, 50)];
    mybtn.firstLabel.text = @"高";
    mybtn.secondLabel.text = @"ff";
    mybtn.centerImage.image = [UIImage imageNamed:@"icon120×120-1"] ;
    [mybtn addTarget:self action:@selector(btn) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:mybtn];

应该不用解释 了 最重要的是看链接 内容很多
