如何防止iOS中同一个UIButton上的多个事件？

Question

我希望防止连续多次点击UIButton.

我试过enabled和exclusiveTouch属性但它没有用.如:

-(IBAction) buttonClick:(id)sender{
    button.enabled = false;
    [UIView animateWithDuration:1.0 delay:0.0 options:UIViewAnimationOptionAllowAnimatedContent animations:^{
        // code to execute
     }
     completion:^(BOOL finished){
         // code to execute  
    }];
    button.enabled = true;
}

Answer 1

你正在做的是,你只需在块外设置启用开/关.这是错误的,它执行一旦这个方法将调用,因此它不会禁用按钮,直到完成块将调用.相反,一旦动画完成,你应该重新启用它.

-(IBAction) buttonClick:(id)sender{
    button.enabled = false;
    [UIView animateWithDuration:1.0 delay:0.0 options:UIViewAnimationOptionAllowAnimatedContent animations:^{
        // code to execute
     }
     completion:^(BOOL finished){
         // code to execute  
        button.enabled = true; //This is correct.
    }];
    //button.enabled = true; //This is wrong.
}

哦,是的,而不是true和false,YES并且NO会看起来很好.:)
