【问题描述】:
我想在两个视图之间创建一个动画,这就是我所做的:
两个视图都包含相同的scrollView,并且视图之间的动画的目的是在scrollView的边缘之间创建动画。
这就是我所做的:
UIView *view1;
UIView *view2;
view1 = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
view2 = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
self.scrollView1 = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 320)];
self.scrollView1.pagingEnabled = YES;
self.scrollView1.delegate = self;
[view1 addSubview:scrollView1];
[self.view addSubview:view1];
当scrollView到达最后一帧时:
- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView
{
//here I verify when the last frame of the scrollView is loaded
if (self.scrollView1.contentOffset.x == self.view.frame.size.width*pathImages.count)
{
[view1 removeFromSuperview];
[self.scrollView1 scrollRectToVisible:CGRectMake(self.view.frame.size.width,0 ,self.view.frame.size.width, self.view.frame.size.height) animated:NO];
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:1.0];
[UIView setAnimationTransition:UIViewAnimationOptionCurveEaseInOut forView:view2 cache:YES];
[view2 addSubview:scrollView1];
[self.view addSubview:view2];
[UIView commitAnimations];
}
}
问题是滚动视图再次从第一个位置加载(应该如此)但没有动画 - 只是突然出现。 谁能告诉我错误在哪里以及解决方法。谢谢:)
