动画期间无法触摸（块动画）

发布于 2024-12-10 03:40:41 字数 439 浏览 4 评论 0原文

我有一个带有 UIButton、UITextField 的视图和一个用于背景的 UIImageView。

在 viewDidLoad 中，我尝试使用块将 UIImageView 从 alpha=0 动画到 alpha =1。这是非常基本的，这是代码：

[UIView animateWithDuration:1.5 animations:^(void){

    ((UIView*)[self.view viewWithTag:123]).alpha = 1;
}completion:^(BOOL finished){
}];

运行良好。但在那 1.5 秒的动画中，我在当前视图中的触摸似乎被禁用了。在动画完成之前我无法单击任何按钮或文本字段。

提前致谢

I have a View with UIButton, UITextField, and a UIImageView for Background.

in viewDidLoad i try animate UIImageView from alpha=0 to alpha =1 using block. it's pretty basic, here's the code:

[UIView animateWithDuration:1.5 animations:^(void){

    ((UIView*)[self.view viewWithTag:123]).alpha = 1;
}completion:^(BOOL finished){
}];

which is working fine. but during that 1.5 seconds of animation, my touch in current view seems to be disabled. i can't click any of the buttons or textFields until animation finish.

Thanks in Advance

您应该使用选项UIViewAnimationOptionAllowUserInteraction，如下例所示：

[UIView animateWithDuration:1.0 
                      delay:0 
                    options:UIViewAnimationOptionAllowUserInteraction 
                 animations:^{ myView.alpha = 0.5; } 
                 completion:NULL];

You should use option UIViewAnimationOptionAllowUserInteraction as in the following example:

[UIView animateWithDuration:1.0 
                      delay:0 
                    options:UIViewAnimationOptionAllowUserInteraction 
                 animations:^{ myView.alpha = 0.5; } 
                 completion:NULL];

对于 Swift 3+,iOS 10 使用 .allowUserInteraction 动画中的 UIView 用户交互

添加到动画调用 UIViewAnimationOptions 标志 .allowUserInteraction

UIView.animate(withDuration: 1.0, delay: 0.0, usingSpringWithDamping: 0.4, initialSpringVelocity: 0.0, options: [.curveEaseIn,.allowUserInteraction], animations: {

            //your animation block

            }, completion: { isAnimated in
            //after animation is done
    })

UIView userinteraction in animation using .allowUserInteraction for Swift 3+,iOS 10

Add to the animation call the UIViewAnimationOptions flag .allowUserInteraction

UIView.animate(withDuration: 1.0, delay: 0.0, usingSpringWithDamping: 0.4, initialSpringVelocity: 0.0, options: [.curveEaseIn,.allowUserInteraction], animations: {

            //your animation block

            }, completion: { isAnimated in
            //after animation is done
    })

看起来动画按钮通常会使它们的点击状态变得非常挑剔。我为此提出的解决方案是让动画元素只是一个具有所有按钮样式的 UIView。在 UIView 动画之前，我向 UIView 上方的视图添加一个真实的按钮，并在我希望用户交互发生的位置提供清晰的背景。确实增加了一个额外的步骤，但非常可靠。

//create button and view
UIButton *viewNotificationBtn = [[UIButton alloc] initWithFrame:CGRectMake(0, ([UIScreen mainScreen].bounds.size.height -70), 320, 50)];
UIView *viewNotificationView = [[UIView alloc] initWithFrame:CGRectMake(0, ([UIScreen mainScreen].bounds.size.height), 320, 50)];

//add elements to screen
[self.view addSubview:viewNotificationView];
[self.view insertSubview:viewNotificationBtn aboveSubview:viewNotificationView];


[UIView animateWithDuration:0.3 delay:0.0 options:UIViewAnimationOptionAllowUserInteraction animations:^{
    [viewNotificationView setFrame:CGRectMake(0, ([UIScreen mainScreen].bounds.size.height - 70), 320, 50)];
} completion:^(BOOL finished) {
    [UIView animateWithDuration:0.5 delay:10.0 options:UIViewAnimationOptionAllowUserInteraction animations:^{
        viewNotificationView.alpha = 0;
    } completion:^(BOOL finished) {
        [viewNotificationView removeFromSuperview];
        [viewNotificationBtn removeFromSuperview];
    }];
}];

Seems like animating buttons in general makes their click states pretty finicky. The solution I came up with for this was to have the animating element just be a UIView with all the button styles. Before the UIView animates I add a real button to the view above the UIView with a clear background to the location I want the user interaction to occur. Definitely adds an extra step but is very dependable.

//create button and view
UIButton *viewNotificationBtn = [[UIButton alloc] initWithFrame:CGRectMake(0, ([UIScreen mainScreen].bounds.size.height -70), 320, 50)];
UIView *viewNotificationView = [[UIView alloc] initWithFrame:CGRectMake(0, ([UIScreen mainScreen].bounds.size.height), 320, 50)];

//add elements to screen
[self.view addSubview:viewNotificationView];
[self.view insertSubview:viewNotificationBtn aboveSubview:viewNotificationView];


[UIView animateWithDuration:0.3 delay:0.0 options:UIViewAnimationOptionAllowUserInteraction animations:^{
    [viewNotificationView setFrame:CGRectMake(0, ([UIScreen mainScreen].bounds.size.height - 70), 320, 50)];
} completion:^(BOOL finished) {
    [UIView animateWithDuration:0.5 delay:10.0 options:UIViewAnimationOptionAllowUserInteraction animations:^{
        viewNotificationView.alpha = 0;
    } completion:^(BOOL finished) {
        [viewNotificationView removeFromSuperview];
        [viewNotificationBtn removeFromSuperview];
    }];
}];
