Jkcountdownbutton, the implementation of the iOS Countdown button, often used for registration, such as sending verification code when the countdown operation.

Here's how to use it:

Code method Creation:

Jkcountdownbutton *button = [Jkcountdownbutton buttonwithtype:uibuttontypecustom];
Button.frame = CGRectMake (M, M, MB);
[Button settitle:@ "Get Authentication Code" 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:@ "%d seconds remaining", second];
        return title;
    }];
    [Sender didfinished:^nsstring * (Jkcountdownbutton *countdownbutton, int second) {
        countdownbutton.enabled = YES;< C13/>return @ "Click Re-Acquire";
 
    }]
 
;

Create with a drag control: first you want button to inherit Jkcountdownbutton class, type set to Custom

@property (Weak, nonatomic) Iboutlet Jkcountdownbutton *button;
 
-(Ibaction) Countdown: (jkcountdownbutton*) Sender {
sender.enabled = NO;
Button type is set to custom otherwise it will flicker
[sender startwithsecond:10.0];
 
[Sender didchange:^nsstring * (Jkcountdownbutton *countdownbutton,int second) {
    nsstring *title = [NSString stringwithformat:@ "%d seconds remaining", second];
    return title;
}];
[Sender didfinished:^nsstring * (Jkcountdownbutton *countdownbutton, int second) {
    countdownbutton.enabled = YES;< C10/>return @ "Click Re-Acquire";}
 
]
