[UIView beginAnimations:nil context:UIGraphicsGetCurrentContext()];

[UIView setAnimationDelay:0.0];
[UIView setAnimationDelegate:self];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:viewHelp cache:YES];
[self.view addSubview:viewHelp];
[UIView commitAnimations];
Where am I doing wrong? I am able to switch the view but I am not able to animate it.
[self.view addSubview:viewHelp]; the animation is just literally adding the subview, you need to work out what animation you want, and then apply it by changing values in the views frame property.?

I want a transition within my app that is like the mystery revolving wall from old scooby doo cartoons. I want the screen to revolve when switching views. Anyone point me in the right direction for the possibility of accomplishing this?
Or this, which uses far less ink:
UIView *bookCaseView; // this is the container... the haunted wall
UIView *booksView; // just an ordinary set of books, right?
UIView *spookyBackside; // ruh-roh, raggy!
[UIView transitionWithView:containerView
duration:0.2
options:UIViewAnimationOptionTransitionFlipFromLeft
animations:^{
[booksView removeFromSuperview];
[bookCaseView addSubview:spookyBackside]; }
completion:NULL];
I think this is what you are looking for:
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1.0];
//optional if you want to do something after the animation
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:#selector(myAnimationDidFinish:finished:context:)];
//
[view2 setFrame:CGRectMake(0, 0, view2.frame.size.width, view2.frame.size.height)];
[view1 addSubview:view2];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:view1 cache:YES];
[UIView commitAnimations];
And to flip back:
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1.0];
//optional if you want to do something after the animation
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:#selector(myOtherAnimationDidFinish:finished:context:)];
//
[view2 removeFromSuperview];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:view1 cache:YES];
[UIView commitAnimations];
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

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)];
Well I would like to have two UIView animation on a same image in the same method like this :
-(void)likeThis{
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.75];
[UIView setAnimationDelegate:self];
image.alpha=0;
[UIView commitAnimations];
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.75];
[UIView setAnimationDelegate:self];
image.transform = CGAffineTransformScale(5,5);
[UIView commitAnimations];
}
But there is only one of these UIView Animation who work.I don't know why.I think there is another way to put two animation for the same image but I don't know how. sorry for my english I'm french :/
You can just put them in the same animation block:
-(void)likeThis
{
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.75];
[UIView setAnimationDelegate:self];
image.alpha=0;
image.transform = CGAffineTransformScale(image.transform,5,5);
[UIView commitAnimations];
}
Note that CGAffineTransformScale takes three arguments:
CGAffineTransformScale(image.transform, 5.0, 5.0)
See http://developer.apple.com/library/mac/documentation/GraphicsImaging/Reference/CGAffineTransform/Reference/reference.html#//apple_ref/doc/uid/TP30000946-CH1g-F16985
Or you could use CGAffineTransformMakeScale:
http://developer.apple.com/library/mac/documentation/GraphicsImaging/Reference/CGAffineTransform/Reference/reference.html#//apple_ref/c/func/CGAffineTransformMakeScale
Do you want them to happen simultaneously, or one after the other? If the former just include them both between a single set of beginAnimations..commitAnimations calls
I add an animation to UIView in my program. There are many controls in the view. I tried to hide some controls before animation, so I set hidden property to YES. But it didn't work.It still visible on the layer during the animation.
here is some code:
button.hidden = YES;
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1.0f];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:self.view cache:YES];
[UIView commitAnimations]
Could any one tell me how to hide controls before animation?
Or how to update control statues(control position, visible, etc)
thanks
If you're trying to animate a view, the statement that sets its new value, like (button.hidden = YES), should be located INSIDE your animation block, like so.
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1.0f];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:self.view cache:YES];
button.hidden = YES;
[UIView commitAnimations];
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];
