下载倒计时按钮JKCountDownButton 代码传送门

JKCountDownButton,实现iOS倒计时按钮,常用于注册等发送验证码的时候进行倒计时操作。

下面介绍其用法：

代码方式创建：

JKCountDownButton *button = [JKCountDownButton buttonWithType:UIButtonTypeCustom];button.frame = CGRectMake(100, 100, 100, 100);[button setTitle:@"获取验证码" forState:UIControlStateNormal];button.backgroundColor = [UIColor blueColor];[self.view addSubview:button]; [button addToucheHandler:^(JKCountDownButton*sender, NSInteger tag) {    sender.enabled = NO;     [sender startWithSecond:10.0];     [sender didChange:^NSString *(JKCountDownButton *countDownButton,int second) {        NSString *title = [NSString stringWithFormat:@"剩余%d秒",second];        return title;    }];    [sender didFinished:^NSString *(JKCountDownButton *countDownButton, int second) {        countDownButton.enabled = YES;        return @"点击重新获取";     }]; }];

用拖控件方式创建：首先你要button继承JKCountDownButton类，type 设置成custom

@property (weak, nonatomic) IBOutlet JKCountDownButton *button; - (IBAction)countDown:(JKCountDownButton*)sender {sender.enabled = NO;//button type要 设置成custom 否则会闪动[sender startWithSecond:10.0]; [sender didChange:^NSString *(JKCountDownButton *countDownButton,int second) {    NSString *title = [NSString stringWithFormat:@"剩余%d秒",second];    return title;}];[sender didFinished:^NSString *(JKCountDownButton *countDownButton, int second) {    countDownButton.enabled = YES;    return @"点击重新获取"; }];}

效果图：
