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;
}
}];

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
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.

I need to flip a card and then flip it back. I have written code to do that with no trouble. The trouble comes because users can flip this card back and forth as many times as they want, and it seems that the effect is cumulative. On the second try, the card spins like a top. I'm not completely surprised, as there only seems to be a way to add animation, not clear one from the view. Is there a way to 're-set' a UIView of any animations I had previously committed? Is there a way to capture it and re-use it without committing a new one? Or am I missing something obvious? This is my code:
if (self.flipped) {
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1.0];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft
forView:self
cache:YES];
[imageView removeFromSuperview];
[UIView commitAnimations];
self.flipped = NO;
} else {
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1.0];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight
forView:self
cache:YES];
[self addSubview:imageView];
[UIView commitAnimations];
self.flipped = YES;
}
Thanks for reading.
To cancel all ongoing animations:
#import <QuartzCore/QuartzCore.h>
...
[view.layer removeAllAnimations];
To start a new animation that kills existing animations, if any, and starts the movement from wherever the view currently is — which I think is what you want:
[UIView beginAnimations:nil context:nil];
[UIView setAnimationBeginsFromCurrentState:YES];
... and the rest of it ...
[UIView commitAnimations];
Hopefully one of those will solve your problem.
Whatever your "self" is, put it in a containing view called foo, and then change your setAnimation... line to this:
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight
forView:foo
cache:YES];
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.
this my code
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:1.5];
if ([sender tag] == 1) {
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:placeholder cache:YES];
}
else {
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.view cache:YES];
}
if (view1OnTop) {
[view1 removeFromSuperview];
[placeholder addSubview:view2];
}
else {
[view2 removeFromSuperview];
[placeholder addSubview:view1];
}
[UIView commitAnimations];
view1OnTop = !view1OnTop;
i want to continuously flip the view, for say some duration 1 min.
it should be continuously flipping.
how can i do it.
what i m trying to is, i want a view, which should be continuously flipping for some particular amount of time.
how can i achieve this?
regards
Apart from the flipping animation, which I presume you have working, you need to initiate a new animation when the current one is finished.
Before [UIView commitAnimations], do this:
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:#selector(animationDone:finished:context:)];
add a function
-(void)animationDone:(NSString*)id finished:(NSNumber*)n context:(void*)context
and let that fire the next round.
edit: you do this by putting in the code to fire an animation, so the typical block from [UIView beginAnimations...] to [UIView commitAnimations]. The better solution of course is to put the animation starting code in a separate function, so the outline will look like:
...
[self startAnimationLoop];
...
-(void)startAnimationLoop
{
[UIView beginAnimtions...];
// do the animation stuff
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:#selector(animationDone:finished:context:)];
[UIView commitAnimations];
}
-(void)animationDone:(NSString*)id finished:(NSNumber*)n context:(void*)context
{
[self startAnimationLoop];
}
to make it go back/forth, add some state variable, or create 2 sets of these functions which call eachother (startAnimationLoop1 and startAnimationLoop2, each one firing the other when done)
