我想使用UIanimationtransitioncurl向右或向左使用动画来进行imageview。可能吗? [英] I want to use animation to imageview using UIanimationtransitioncurl right or left. Is it possible?
问题描述
我想像我的书页一样为我的照片库添加动画效果。
是否有任何方法可以在左侧或右侧使用UIanimationtransitioncurl?
I want to animate my photo gallery like the pages of the book. Is there any method with that I can use UIanimationtransitioncurl in either the left or right side?
这是您向我建议的代码。我已经在viewdidload方法上完成了分配。
This is the code as you have suggested to me. I have done the allocation on the viewdidload method.
self.title = @"TransitionsTitle";
// Create the container view which we will use for transition animation (centered horizontally).
CGRect frame = CGRectMake(round((self.view.bounds.size.width - kImageWidth) / 2.0),
kTopPlacement, kImageWidth, kImageHeight);
self.containerView = [[[UIView alloc] initWithFrame:frame] autorelease];
[self.view addSubview:self.containerView];
// The container view can represent the images for accessibility.
[self.containerView setIsAccessibilityElement:YES];
[self.containerView setAccessibilityLabel:NSLocalizedString(@"ImagesTitle", @"")];
// Create the initial image view.
frame = CGRectMake(0.0, 0.0, kImageWidth, kImageHeight);
self.mainView = [[[UIImageView alloc] initWithFrame:frame] autorelease];
self.mainView.image = [UIImage imageNamed:@"scene1.jpg"];
[self.containerView addSubview:self.mainView];
// Create the alternate image view (to transition between).
CGRect imageFrame = CGRectMake(0.0, 0.0, kImageWidth, kImageHeight);
self.flipToView = [[[UIImageView alloc] initWithFrame:imageFrame] autorelease];
self.flipToView.image = [UIImage imageNamed:@"scene2.jpg"];
CGAffineTransform rotate=CGAffineTransformMakeRotation(3.14/2);
[containerView setTransform:rotate];
[self.view addSubview:containerView];
rotate=CGAffineTransformMakeRotation(-3.14/2);
[mainView setTransform:rotate];
[self.containerView addSubview:mainView];
[self.mainView addSubview:flipToView];
//我把它放在按钮动作事件上。
// I have put it on button action event.
- (IBAction)flipAction:(id)sender{
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:4];
[UIView setAnimationTransition:([self.mainView superview] ?
UIViewAnimationTransitionCurlDown : UIViewAnimationTransitionCurlDown)
forView:self.containerView cache:YES];
if ([flipToView superview])
{
[self.flipToView removeFromSuperview];
[self.containerView addSubview:mainView];
}
else
{
[self.mainView removeFromSuperview];
[self.containerView addSubview:flipToView];
}
[UIView commitAnimations];
}
推荐答案
是的,你可以。这是我用来的代码,
Yes, you can. This is the code I use for that,
self.containerViewParent = [[[UIView alloc] initWithFrame:CGRectMake(what ever you want)] autorelease]; //Create a container parent for the container view.
self.containerView = [[[UIView alloc] initWithFrame:GRectMake(what ever you want)] autorelease]; //Create a container view for the view you wish to display.
CGAffineTransform rotate = CGAffineTransformMakeRotation(-3.14/2);
[containerViewParent setTransform:rotate]; //Rotate the containerViewParent.
[self.view addSubview:containerViewParent];//Add it to the main view.
rotate = CGAffineTransformMakeRotation(3.14/2);
[containerView setTransform:rotate];//Rotate the containerView.
[self.containerViewParent addSubview:containerView]; //Add it to the self.containerViewParent.
[self.containerView addSubview:viewToDisplay]; //Add the view you want to display.
然后将转换应用于父视图,
And then apply the transition to the parent view,
[UIView beginAnimations:@"page transition" context:nil];
[UIView setAnimationDuration:2.0];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:self.containerView cache:YES];
[UIView commitAnimations];
当你上下翘起时,它会向左或向右弯曲。
It will curl to the left or the right when you curl up and down.
**请注意,您需要使用视图的偏移来使其正确显示,
但它对我来说很有用。
**Note that you will need to play with the offset of the views to make it display correctly, but it works great for me.
