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

#import <UIKit/UIKit.h>typedef NS_ENUM(NSUInteger, CustomButtonStatus){    CustomButtonStatusNormal = 0,    CustomButtonStatusReverse = 1};@interface CustomButton : UIButton@PRoperty(nonatomic) CustomButtonStatus buttonStatus;@end

CustomButton.m

#import "CustomButton.h"@implementation CustomButton- (void)setButtonStatus:(CustomButtonStatus)buttonStatus{    NSString *title;    if (CustomButtonStatusNormal == buttonStatus) {        title = @"啊啊啊";    } else if(CustomButtonStatusReverse == buttonStatus){        title = @"哦哦哦";    }    [self setTitle:title forState:UIControlStateNormal];    _buttonStatus = buttonStatus;}@end

调用

#import "ViewControllerTest.h"#import "CustomButton.h"@interface ViewControllerTest () {    CustomButton *button;}@end@implementation ViewControllerTest- (void)viewDidLoad {    [super viewDidLoad];        self.view.backgroundColor = [UIColor whiteColor];        button = [CustomButton buttonWithType:UIButtonTypeCustom];    [button setButtonStatus:CustomButtonStatusNormal];    [button setFrame:CGRectMake(200, 80, 86, 42)];    [button addTarget:self action:@selector(customButtonClick:) forControlEvents:UIControlEventTouchUpInside];    [button setBackgroundColor:[UIColor redColor]];    [self.view addSubview:button];}-(void) customButtonClick: sender{    button.buttonStatus = !button.buttonStatus;}
