Code

@property(nonatomic,strong) LFCountDownButton *countDownButton;

//创建倒计时按钮
 self.countDownButton = [[LFCountDownButton alloc]init];
 self.countDownButton.frame = CGRectMake(10, 130, 150, 40);
[self.countDownButton.titleLabel setFont:[UIFont systemFontOfSize:14.0f]];
[self.countDownButton setTitle:@"Start CountDown" forState:UIControlStateNormal];
[self.countDownButton setBackgroundColor:[UIColor redColor]];
[self.view addSubview:self.countDownButton];

// 1. 倒计时按钮点击
[self.countDownButton touchCountDownButtonHandler:^(LFCountDownButton *countDownButton, NSInteger tag) {

    countDownButton.enabled = NO;

    //1.1开始倒计时
    [countDownButton startCountDownWithSecond:10];

    //do something...

    //1.2 倒计时进行中
    [countDownButton countDownButtonChanging:^NSString *(LFCountDownButton *countDownButton, NSUInteger second) {

        NSString *title = [NSString stringWithFormat:@"%zd left",second];
        return title;

    }];

    //1.3 倒计时结束
    [countDownButton countDownButtonFinished:^NSString *(LFCountDownButton *countDownButton, NSUInteger second) {

        countDownButton.enabled = YES;
        return @"Obtain again";

    }];

}];

xib

@property (weak, nonatomic) IBOutlet LFCountDownButton *countDownButtonXib;

1.拖拽button控件到xib
2.修改button控件的的类,button type要设置成custom 否则会闪动
3.设置IBAction方法

- (IBAction)countDownButtonClickForXib:(id)sender {

 //要么拖拽方法的时候改变type(id改为LFCountDownButton类型),要么自己转下
 self.countDownButtonXib = (LFCountDownButton*)sender;
 self.countDownButtonXib.enabled = NO;

//1.1开始倒计时
[ self.countDownButtonXib startCountDownWithSecond:15];

//do something...

//1.2 倒计时进行中
[ self.countDownButtonXib countDownButtonChanging:^NSString *(LFCountDownButton *countDownButton, NSUInteger second) {

    NSString *title = [NSString stringWithFormat:@"%zd left",second];
    return title;

}];

//1.3 倒计时结束
[ self.countDownButtonXib countDownButtonFinished:^NSString *(LFCountDownButton *countDownButton, NSUInteger second) {

    countDownButton.enabled = YES;
    return @"Obtain again";
}];
}
