iOS 自定义UIButton

nonocast

工作中有一个点击button更新button上文案的需求,用自定义了button可以很简单的实现的这个需求

首先写个自定义的button

CustomButton.h

1. #import <UIKit/UIKit.h>
   
2. 
   
3. typedef NS_ENUM(NSUInteger, CustomButtonStatus){
   
4.     CustomButtonStatusNormal = 0,
   
5.     CustomButtonStatusReverse = 1
   
6. };
   
7. 
   
8. @interface CustomButton : UIButton
   
9. 
   
10. @property(nonatomic) CustomButtonStatus buttonStatus;
    
11. 
    
12. @end

复制代码

CustomButton.m

1. #import "CustomButton.h"
   
2. 
   
3. @implementation CustomButton
   
4. 
   
5. - (void)setButtonStatus:(CustomButtonStatus)buttonStatus{
   
6.     NSString *title;
   
7.     if (CustomButtonStatusNormal == buttonStatus) {
   
8.         title = @"啊啊啊";
   
9.     } else if(CustomButtonStatusReverse == buttonStatus){
   
10.         title = @"哦哦哦";
    
11.     }
    
12.     [self setTitle:title forState:UIControlStateNormal];
    
13.     _buttonStatus = buttonStatus;
    
14. 
    
15. }
    
16. @end

复制代码

调用

1. #import "ViewControllerTest.h"
   
2. #import "CustomButton.h"
   
3. 
   
4. @interface ViewControllerTest () {
   
5.     CustomButton *button;
   
6. }
   
7. 
   
8. @end
   
9. 
   
10. @implementation ViewControllerTest
    
11. 
    
12. - (void)viewDidLoad {
    
13.     [super viewDidLoad];
    
14.    
    
15.     self.view.backgroundColor = [UIColor whiteColor];
    
16.    
    
17.     button = [CustomButton buttonWithType:UIButtonTypeCustom];
    
18.     [button setButtonStatus:CustomButtonStatusNormal];
    
19.     [button setFrame:CGRectMake(200, 80, 86, 42)];
    
20.     [button addTarget:self action:@selector(customButtonClick:) forControlEvents:UIControlEventTouchUpInside];
    
21.     [button setBackgroundColor:[UIColor redColor]];
    
22.     [self.view addSubview:button];
    
23. 
    
24. }
    
25. 
    
26. -(void) customButtonClick: sender{
    
27.     button.buttonStatus = !button.buttonStatus;
    
28. }

复制代码
