Uiview 从右向左推送动画的顺序
我使用的方法是:Uiview 从右向左推送动画的顺序,uiview,uiviewcontroller,uistoryboardsegue,uiviewanimationtransition,Uiview,Uiviewcontroller,Uistoryboardsegue,Uiviewanimationtransition,我使用的方法是: [UIView transitionWithView: duration: options: animations: completion:]; 控制序列上的反向动画。准确地使用此代码: [UIView transitionWithView:self.view.superview duration:2.0 options:UIViewAnimationOptionTransitionFlipFromRi
[UIView transitionWithView: duration: options: animations: completion:];
控制序列上的反向动画。准确地使用此代码:
[UIView transitionWithView:self.view.superview
duration:2.0
options:UIViewAnimationOptionTransitionFlipFromRight
animations:^{
[self dismissModalViewControllerAnimated:NO];
}
completion:nil];
这是可行的,但我真正想要的不是翻转,而是推动。换句话说,我希望看到视图从右向左滑动,一个替换另一个
不幸的是,没有UIViewAnimationOptionTransitionPushFromRight
因此,我的问题是:如何获得我想要的效果?如果您使用的是navigationController,您可以执行以下操作:
- (void)perform
{
UIViewController *source = (UIViewController*)[self sourceViewController];
UIViewController *destination = (UIViewController*)[self destinationViewController];
CATransition* transition = [CATransition animation];
transition.duration = .25;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = kCATransitionPush;
transition.subtype = kCATransitionFromLeft;
[source.navigationController.view.layer addAnimation:transition
forKey:kCATransition];
[source.navigationController pushViewController:destination animated:NO];
}
如果您不想使用UINavigationController
,并且希望源代码视图控制器与使用presentViewController
相反消失,并且不希望使用kCATransitionPush
导致动画淡出,则以下解决方案将起作用。如果您的视图是透明的,并且您不希望包含的背景设置动画,则此操作也有效
static UIImageView *screenShotOfView(UIView *view)
{
// Create a snapshot for animation
UIGraphicsBeginImageContextWithOptions(view.bounds.size, NO, 0.0);
CGContextRef context = UIGraphicsGetCurrentContext();
[view.layer renderInContext:context];
UIImageView *screenShot = [[UIImageView alloc] initWithImage:UIGraphicsGetImageFromCurrentImageContext()];
UIGraphicsEndImageContext();
return screenShot;
}
- (void)perform
{
UIViewController *source = (UIViewController *) self.sourceViewController;
UIViewController *destination = (UIViewController *) self.destinationViewController;
// Swap the snapshot out for the source view controller
UIWindow *window = source.view.window;
UIImageView *screenShot = screenShotOfView(source.view);
CGRect originalFrame = destination.view.frame;
BOOL animsEnabled = [UIView areAnimationsEnabled];
[UIView setAnimationsEnabled:NO];
{
window.rootViewController = destination;
[window addSubview:screenShot];
[source.view removeFromSuperview];
CGRect frame = destination.view.frame;
frame.origin.x += source.view.bounds.size.width;
destination.view.frame = frame;
}
[UIView setAnimationsEnabled:animsEnabled];
[UIView animateWithDuration:kAnimationDuration
animations:^{
destination.view.frame = originalFrame;
CGRect frame = screenShot.frame;
frame.origin.x -= screenShot.bounds.size.width;
screenShot.frame = frame;
}
completion:^(BOOL finished) {
[screenShot removeFromSuperview];
}];
}
