用于Webview的滑动过渡动画

Question

我在从右向左滑动手势后为webview加载新内容.执行手势后,webview会加载其新内容.如何为此webview制作动画,该动画会根据手势显示webview内容的"滑动"？因此,当用户从右向左滑动时,webview也应该从右向左移动.并最终"飞走".我认为有些音乐应用可以通过刷一个来加载新音轨.谢谢!

您可以UIWebView通过以下代码应用单一滑动动画.

- (void)viewDidLoad
{
    [super viewDidLoad];

    UISwipeGestureRecognizer *recognizerRight;
    recognizerRight.delegate=self;

    recognizerRight = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeRight:)];
    [recognizerRight setDirection:UISwipeGestureRecognizerDirectionRight];
    [webView addGestureRecognizer:recognizerRight];


    UISwipeGestureRecognizer *recognizerLeft;
recognizerLeft.delegate=self;
    recognizerLeft = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeleft:)];
    [recognizerLeft setDirection:UISwipeGestureRecognizerDirectionLeft];
    [webView addGestureRecognizer:recognizerLeft];


}

现在应用滑动效果的帮助CATransition.

-(void)swipeleft:(UISwipeGestureRecognizer *)swipeGesture
{


        CATransition *animation = [CATransition animation];
        [animation setDelegate:self];
        [animation setType:kCATransitionPush];
        [animation setSubtype:kCATransitionFromRight];
        [animation setDuration:0.50];
        [animation setTimingFunction:
         [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
        [webView.layer addAnimation:animation forKey:kCATransition];



}
-(void)swipeRight:(UISwipeGestureRecognizer *)swipeGesture
{

        CATransition *animation = [CATransition animation];
        [animation setDelegate:self];
        [animation setType:kCATransitionPush];
        [animation setSubtype:kCATransitionFromLeft];
        [animation setDuration:0.40];
        [animation setTimingFunction:
         [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
        [webView.layer addAnimation:animation forKey:kCATransition];


}

希望这对你有所帮助.
