I have screens: 1st one is xib and 2nd is the controller when I dismiss screen 2. Both screens get dismissed instead of the 2nd controller.
in iOS(Xcode)
if you want remove xib then you just need to removeFromSuperview so only xib will remove.and also please share your code so we can get idea what you did.
[subview removeFromSuperview]
.. and if you want to remove viewcontroller as a subview you need to do
yourViewController.willMove(toParentViewController: nil)
yourViewController.view.removeFromSuperview()
yourViewController.removeFromParentViewController()
1) refer this link for more info 2)Link2
You should Animation with two views.
presentedView.transform = CGAffineTransformTranslate(presentedView.transform, 0, DEVICE_HEIGHT);
[UIView animateWithDuration:0.6f delay:0 usingSpringWithDamping:1 initialSpringVelocity:0 options:UIViewAnimationOptionCurveEaseInOut animations:^{
presentedView.transform = CGAffineTransformIdentity;
} completion:^(BOOL finished) {
appDelegate.window.rootViewController = appDelegate.welcomeViewctrl;
}];

I am using Autolayout and animating by changing the constraints, however, in iOS7 the view simply jumps to the end position - in iOS6 I get a nice animation.
Is should be noted these views are UICollectionViews and I have checked the Storyboard and there are no Layout errors.
All I can think is there is something and am or am not setting on the Storyboard or something that I am doing wrong with the Constant settings in the Storyboard.
primaryMenuYContraints.constant = BUTTOMX;;
leftMenuYContraints.constant = 136.0f;
leftMenuBottomConstraint.constant = 5.0f;
[UIView animateWithDuration:0.7f
delay:0.0f
options:UIViewAnimationOptionCurveLinear
animations:^
{
// Move in menus
[self.primaryOptionCollection layoutIfNeeded];
[self.menuOptionCollection layoutIfNeeded];
}
completion:^(BOOL finished)
{
}];
I changed to and now works in both iOS7 and 6, still not sure why it does/did it though! I still think I am setting something up wrong in the Storyboard. I am add another view (nothing to do with this lot) programmatically so I believe that is based around frames until I convert it (which I am not doing).
primaryMenuYContraints.constant = BUTTOMX;;
leftMenuYContraints.constant = 136.0f;
leftMenuBottomConstraint.constant = 5.0f;
[UIView animateWithDuration:0.7f
delay:0.0f
options:UIViewAnimationOptionCurveLinear
animations:^
{
// Move in menus
[self.view layoutIfNeeded];
}
completion:^(BOOL finished)
{
}];
I have no idea, why it is not working.
All I want to do is a simple UIView animation in the viewDidLoad.
Here's my code:
[UIView animateWithDuration:3.0f animations:^{
[self.headline setCenter:CGPointMake(0.0, 200.0)];
}];
Nothing happens. When I test the general approach of calling a animation method on that particular object like this:
[UIView animateWithDuration:3.0f animations:^{
[self.headline setAlpha:0.0];
}];
it works!!! Why am I not able to move the view across the screen? I am using latest Xcode 4.5.
Thanks for any advice!
UPDATE:
When I add a view manually in code it works. But for the UIViews I create as Outlets in the Interface Builder it doesn't work.
UILabel *testLabel = [[UILabel alloc] initWithFrame:CGRectMake(0.0, 0.0, 200.0, 100.0)];
testLabel.backgroundColor = [UIColor redColor];
[self.view addSubview:testLabel];
[UIView animateWithDuration:3.0 animations:^{
testLabel.center = CGPointMake(0.0, 200);
}];
So obviously I am doing something wrong in the .xib file
Dont do it in viewDidLoad. The view is not pressent at that time yet.
Try it in viewDidAppear.
Well, I think the reason for the missing animation was the fact that I called a different push navigation animation from the view controller that was pushing the actual view on screen:
- (IBAction)goForSelection:(id)sender
{
SelectionViewController *selectionViewController = [[SelectionViewController alloc] initWithNibName:#"SelectionViewController" bundle:nil];
//[self.navigationController pushViewController:selectionViewController animated:YES];
[UIView transitionWithView:self.navigationController.view duration:1.0 options:UIViewAnimationOptionTransitionFlipFromRight animations:^{
[self.navigationController pushViewController:selectionViewController animated:NO];
} completion:^(BOOL finished) {
[selectionViewController startIntroAnimation];
}];
}
First I checked what happens when I use the default navigation controller segue. And to my surprise the animation did start. Then I inserted the call to the [selectionViewController startIntroAnimation] to the completion block and this works as well.
Im trying to present a view translucently and that the previous view sticks around and be that its visible in the background.
I've got
[self presentModalViewController:modalView animation:YES];
and I have the transparency set in the modalView's viewDidLoad, but after modalView gets brought up the previous view disappears. What can I do to keep the other view to stay around in the background?
I have also tried adding it with
[self.view addSubview:modalView.view];
It doesn't cover the whole screen, I would like to be able to solve this problem using presentModalViewController method.
It sounds like you just want a view to be displayed on top of your main view. Modal views are a finicky way of presenting subviews, instead you should look at creating a simple view class to add to your view controller. You can then use [UIView animate...]; method to animate it in and out of view.
To get you started:
- (void)displayViewButtonPressed(id)sender
{
if (!self.topView)
{
UIView *overlayView = [[UIView alloc] initWithFrame:CGRectMake(44.0f, 22.0f, 40.0f, 44.0f];
[overlayView setAlpha:0.0f];
[overlayView setBackgroundColor:[UIColor redColor]];
[self setTopView:overlayView];
[overlayView release];
}
[self.view addSubView:self.topView];
[UIView animateWithDuration:0.5
animations:^{
[self.topView setAlpha:1.0f];
}];
}
In the above method we create a custom UIView and animate it into position. We maintain a pointer to it so we can remove it later (like so:)
- (void)dismissViewButtonTapped:(id)sender
{
[UIView animateWithDuration:0.5
animations:^{
[self.topview setAlpha:0.0f];
}
completion:^(BOOL finished) {
[self.topView removeFromSuperView];
}
}
Its a little more work that using modal views, but it gives you much more flexibility in regards to what you use and how you display it.
Hope this helps:)
hello all i am using this code to show flip animation...... i have a uiview with scrollview(paging enabled)...so it shows a view like a page...now i also have done flip animation using this code....
-(void)flipView
{
flashCardAnswerController *flashCardAnswerControllerobj = [[flashCardAnswerController alloc] initWithNibName:#"FlashCardAnswerView" bundle:[NSBundle mainBundle]];
[flashCardAnswerControllerobj.view setFrame:[[self view] frame]];
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.60];// Sub. duration
UIView *superview;
if ((superview = [[self view] superview])) {
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:superview cache:YES];
[superview addSubview:[flashCardAnswerControllerobj view]];
}
[UIView commitAnimations];
}
so according to code the new view will be added to scrollview..i also manage to release the new view while flipping back...but if i directly push the back button on navigaion controller...the flip side view won't release. i tried this in dealloc method of my scrolleview's class but it doesn't work
for(UIView *subview in [scrollView subviews]) {
[subview removeFromSuperview];
}
how do i remove flipside's view the views are very much in number...approx. 48 plus 48 flip side views so definietly it will create memory issues on device...
also could someone tell me a way to disable NavigationBar's back button in flip side view...without creating scolling class's object.
I do not have a direct answer to your question, but I can tell that this is the old iPhone OS 2.x way of displaying a views flip-side.
In iPhone OS 3.0 you should use presentModalViewController:animated: instead. This is much less code, and all of the problems you describe in your questions goes away.
The idea is that the flip-side of the current view, is managed by a separate UIViewController that you display modally. But in addition to the sliding animation from 2.0 you can also have the new view controller animate in and out with a horizontal flip.
self.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentModalViewController:flipSideController
animated:YES];
[[scrollView subviews] makeObjectsPerformSelector:#selector(removeFromSuperview)]
I'm trying out a multiple view application, but I can't seem to get the first view controller to go away when I bring in the new view controller. I'm laying the second (coming) view controller at index 0, and it's just placing it in the background. I thought the [going.view removeFromSuperview] would remove the original viewcontroller, but that's not what is happening...
UIViewController *coming = nil;
UIViewController *going = nil;
UIViewAnimationTransition transition;
if (answer == YES)
{
coming = boyController;
going = getInfoController;
transition = UIViewAnimationTransitionFlipFromLeft;
}
else
{
coming = girlController;
going = getInfoController;
transition = UIViewAnimationTransitionFlipFromLeft;
}
NSLog(child);
[UIView setAnimationTransition:transition forView: self.view cache:YES];
[coming viewWillAppear:YES];
[going viewWillDisappear:YES];
[going.view removeFromSuperview];
[self.view insertSubview:coming.view atIndex:0];
[going viewDidDisappear:YES];
[coming viewDidAppear:YES];
[UIView commitAnimations];
First a little refactoring:
coming = (answer ? boyController : girlController);
You can delete going and transition, as they're only used once. Then, to actually do the animation, you need to put everything in the context of an animation block.
[UIView beginAnimations:#"flipAnimation" context:NULL];
[UIView setAnimationTransition:transition forView:self.view cache:YES];
[getInfoController.view removeFromSuperview];
[self.view addSubview:coming.view];
[UIView commitAnimations];
viewWillAppear: and viewWillDisappear: are delegate methods. These will be called automatically on those views' delegates, if any. They shouldn't ever be called manually.
