禁用UIControl一段时间

Question

我可以短时间禁用按钮吗？我有一个注册视图,在3次错误尝试时它会将用户带到注册视图之外,它将禁用注册按钮一段时间,比如说5分钟.可能吗？

Answer 1

- (void) processAfterWrongAttempts {
    button.enabled = NO;

    double delayInSeconds = 5.0 * 60;
    dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, (int64_t)(delayInSeconds *   NSEC_PER_SEC));
    dispatch_after(popTime, dispatch_get_main_queue(), ^(void){
        button.enabled = YES;
    });
}
