JKCountDownButton,子類化UIButton實現IOS倒計時按鈕,常常用于注冊等發送驗證碼的時候進行倒計時操作

代碼方式使用

JKCountDownButton *_countDownCode;
_countDownCode = [JKCountDownButton buttonWithType:UIButtonTypeCustom];
_countDownCode.frame = CGRectMake(81, 200, 108, 32);
[_countDownCode setTitle:@"開始" forState:UIControlStateNormal];
_countDownCode.backgroundColor = [UIColor blueColor];
[self.view addSubview:_countDownCode];

[_countDownCode addToucheHandler:^(JKCountDownButton*sender, NSInteger tag) {
    sender.enabled = NO;

    [sender startWithSecond:10];

    [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 @"點擊重新獲取";

    }];

}];

xib方式使用

@property (weak, nonatomic) IBOutlet JKCountDownButton *countDownXib;

- (IBAction)countDownXibTouched:(JKCountDownButton*)sender {
sender.enabled = NO;
//button type要 設置成custom 否則會閃動
[sender startWithSecond:10];

[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 @"點擊重新獲取";

}];}
