    用label和imageView实现button的功能 其中点击方法使用手势来写的

    首先创建两个类 一个是用label实现button的类 另一个是用imageView来实现button的类 这两个类都是“+”方法 都继承于UIView 返回值分别是label和imageView

    #import <UIKit/UIKit.h>
    
    @interface LabelButton : UIView
    + (UILabel *)createButtonFrame:       (CGRect)frame view:(UIView *)view    buttonName:(NSString *)buttonName color:(UIColor *)color tap:  (UITapGestureRecognizer *)tap;
    
    @end
    
    
    #import "LabelButton.h"
    
    @implementation LabelButton
    + (UILabel *)createButtonFrame:    (CGRect)frame view:(UIView *)view buttonName:(NSString *)buttonName color:(UIColor *)color tap:(UITapGestureRecognizer *)tap {
    UILabel *label = [[UILabel alloc] initWithFrame:frame];
    label.text = buttonName;
    label.backgroundColor = color;
    [view addSubview:label];
    label.userInteractionEnabled = YES;
    [label addGestureRecognizer:tap];
    
    return label;
    }
    
    @end
    
    
    #import <UIKit/UIKit.h>
    
    @interface ImageViewButton : UIView
    + (UIImageView *)createButtonFrame:(CGRect)frame view:(UIView *)view image:(UIImage *)image tap:(UITapGestureRecognizer *)tap;
    
    @end
    
    #import "ImageViewButton.h"
    
    @implementation ImageViewButton
    + (UIImageView *)createButtonFrame: (CGRect)frame view:(UIView *)view image:(UIImage *)image tap:(UITapGestureRecognizer *)tap {
    UIImageView *imageView = [[UIImageView alloc] initWithFrame:frame];
    UIImage *buttonImage = image;
    [imageView setImage:buttonImage];
    imageView.userInteractionEnabled = YES;
    [view addSubview:imageView];
    [imageView addGestureRecognizer:tap];
    return imageView;
    }
    @end
    
    
    #import "ViewController.h"
    #import "LabelButton.h"
    #import "ImageViewButton.h"
    
    @interface ViewController ()
    
    @end
    
    @implementation ViewController
    
    - (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    self.view.backgroundColor = [UIColor whiteColor];
    UILabel *label = [[UILabel alloc] init];
    UITapGestureRecognizer *labelTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(labelClick:)];
    label = [LabelButton createButtonFrame:CGRectMake(20, 100, 90, 30) view:self.view buttonName:@"确认" color:[UIColor redColor] tap:labelTap];
    
    UIImageView *imageView = [[UIImageView alloc]init];
    UITapGestureRecognizer *imageButtonTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(imageClick:)];
    imageView = [ImageViewButton createButtonFrame:CGRectMake(20, 150, 260, 150) view:self.view image:[UIImage imageNamed:@"u=3730821670,510701542&fm=21&gp=0.jpg"] tap:imageButtonTap];
    
    }
    - (void)labelClick:(UITapGestureRecognizer *)tap {
    NSLog(@"确认就确认呗");
    }
    
    - (void)imageClick:(UITapGestureRecognizer *)tap {
    NSLog(@"我最可爱 哼");
    }
    
    - (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
    }
    
    @end
