This is my current code, but it seems to just be flipping the view - I want it to flip-in i.e. flip for not seeing it to seeing it. I am doing this in the viewdidload method:
[UIView animateWithDuration:1.5 delay:0.0 options:UIViewAnimationOptionOverrideInheritedDuration animations:^{
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.alertView cache:YES];
}completion:^(BOOL finished)
{
}];
Use the transitionFromView:toView:duration:options:completion: method with a full transpatent view as 'FromView' and your alertView as toView

I am using page Curl up animation. I am showing one question on view, when i clicks on button it animates page curl up and shows black screen. But i want to show same view again with different question after page curl up. How to show same view with different question after page curl up animation?
i am using below code
[UIView beginAnimations:#"partialPageCurlUp" context:nil];
[UIView setAnimationDuration:1.5];
[UIView setAnimationsEnabled:YES];
[UIView setAnimationDelegate:self];
[UIView setAnimationsEnabled:YES];
[UIView
setAnimationTransition: UIViewAnimationTransitionCurlUp
forView:self.view cache:YES];
[UIView commitAnimations];
[super viewDidLayoutSubviews];
just want to know what to do next?
[UIView animateWithDuration:0.25 animations: ^{ // your animation code hear } completion:^ (BOOL finished) { if (finished) { // Your Animation Completion call back. NSLog(#"Is completed"); } } ];
Try this method.
See you just need to implement few things more
Add animation Stop Selector in your existing code so that you may get the Animation finish point could display the next question
[UIView setAnimationDidStopSelector:#selector(animationDidStopFinished)];
animationDidStopFinished this would another method you should write some piece of code which will display another question as animation gets finished.
or use below code
[UIView animateWithDuration:1.5 delay:.00 options:UIViewAnimationTransitionFlipFromLeft animations:^
{
//here you should write animation code
[UIView
setAnimationTransition: UIViewAnimationTransitionCurlUp
forView:self.view cache:YES];
}
completion:^ (BOOL finished) {
if (finished) {
// Here You may show Next Question as animation gets stop;
}
}];
In my viewcontroller i am using animation for changing the frame of UIButton and UIView, going from portrait to landscape user can see views growing but problem is animation is leaking everywhere and showing everything coming from different sides.
Here is the code
[UIView beginAnimations:Nil context:Nil];
[UIView setanimationDuration:1];
[view1 setFrame:CGRectMake(100,100,200,300)];
[UIView commitAnimations];
Thanks
Please elaborate more on what "leaking everywhere" means, and does it make a difference if you use block animation:
[UIView animateWithDuration:1.0 delay:0.0 options:nil animations:^{
[view1 setFrame:CGRectMake(100,100,200,300)];
}completion:^(BOOL done){
if (done) {
NSLog(#"animation complete");
}
}];
According to Apple's documentation:
In iOS 4 and later, use the block-based animation methods.
(Recommended)
I have one view controller which contains two views (redView, blueView). The views are smaller than the main view.
I want to change from redView to blueView with animation. If use this none animation happens.
[UIView beginAnimations:#"View Flip" context:nil];
[UIView setAnimationDuration:1.25];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationTransition: UIViewAnimationTransitionFlipFromRight
forView:redView cache:YES]; // !!! I WILL CHANGE THIS
[self.view addSubview:blueView];
[redView removeFromSuperview];
[UIView commitAnimations];
In case I change the code to this, then the animation is ok but the whole mainView animates, something that i do not want to happen. I want only the subViews to flip. I should note that the 2 subviews are in the same position. (frame) Any ideas?
[UIView beginAnimations:#"View Flip" context:nil];
[UIView setAnimationDuration:1.25];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationTransition: UIViewAnimationTransitionFlipFromRight
forView:self.view cache:YES];
[self.view addSubview:blueView];
[redView removeFromSuperview];
[UIView commitAnimations];
Use Block animation instead of simple animation, from apple about simple animation "Use of the methods in this section is discouraged in iOS 4 and later"
Animation With Block's
[UIView transitionWithView:containerView
duration:1.25
options:UIViewAnimationOptionTransitionFlipFromRight
animations:^
{
[redView removeFromSuperview];
[containerView addSubview:blueView];
}
completion:NULL];
containerView : is main view that will be animated.
Also add to your containerView redView,
that all :)
for more info look at
http://developer.apple.com/library/ios/#documentation/uikit/reference/uiview_class/uiview/uiview.html
Solution Found:
I use a tempView for which i do the animation. Onto the tempView I add view1 and view2.
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1.0];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:tempView cache:YES];
[tempView addSubview:view2];
[view1 removeFromSuperview];
[UIView commitAnimations];
Extra: For a better animation you can use view1.visible = YES , NO instead of addSubview, removeFromSuperView, but they will be allocated all the time
In your first example it looks like you are deleting the redView before it can animate, try deleting it after the animation.
Code:
[UIView setAnimationDidStopSelector:#selector(removeRedViewFromSuperview)];
I have a working view animation, that curls up a container view, while the containerview.subviews changes. (before the animation a UITableView will be shown, after it is a custom view, name keypadView)
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:.75];
[UIView setAnimationDelegate:self];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlUp
forView:containerView
cache:YES];
[secondView removeFromSuperview];
[containerView addSubview:keypadView];
[UIView commitAnimations];
Now I want to rewrite this code for the iOS4 block-based api, as I want to use the completion block. I wrote this:
[UIView transitionWithView:containerView
duration:.75
options:UIViewAnimationTransitionCurlUp
animations:^{
NSLog(#"Hey Ho");
[secondView removeFromSuperview];
[containerView addSubview:keypadView];
}
completion:NULL];
The views switch — but not animated.
what is wrong with my code?
Edit
completion: ^(BOOL completed){
NSLog(#"completed %d", completed);
}
doesn't help, as NULL is an accepted value, according to the docs
do:
options:UIViewAnimationOptionTransitionCurlUp
instead of:
options:UIViewAnimationTransitionCurlUp
That is why your code works now :).
The sample in the UIView class reference may be wrong - or maybe there's a bug with adding and removing views in the animations block object, but the only way I've been able to get it to work is as follows:
[secondView removeFromSuperview];
[containerView addSubview:keypadView];
[UIView transitionWithView:containerView
duration:.75
options:UIViewAnimationOptionTransitionCurlUp
animations:^{}
completion:^(BOOL finished) {
NSLog(#"finished %d", finished);
}];
Did you leave [UIView beginAnimations:nil context:nil]; above your new block?
Is the completion block always NULL? Try putting an NSLog statement in there or something. I don't know if NULL blocks would mess it up.
i have used viewcontroller with multiple view.
when i go back to previous, there is no animation
i have tried by below lines of code ,
-(IBAction)goback
{
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:1];
[UIView setAnimationTransition: UIViewAnimationTransitionCurlDown forView:self.view cache:YES];
[self.view removeFromSuperview];
[UIView commitAnimations];
}
You can't animate a method call. You can only animate properties of the view such as frame, size, alpha etc. removeFromSuperview isn't a property, it is a method that simply finds the superview and removes the originating view from the array of subviews.
You need to run the animation and then send removeFromSuperview when the animation completes.
use below code
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:1];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:self.view.superview cache:YES];
[self.view removeFromSuperview];
[UIView commitAnimations];
