I know this code is available to UINavigationController only.
[self.navigationController setNavigationBarHidden:YES animated:YES];
An example using blocks. This will hide a toolbar at the top of an iPad screen.
[UIView animateWithDuration:.7
animations:^(void)
{
CGRect toolbarFrame = self.toolbar.frame;
toolbarFrame.origin.y = -44; // moves iPad Toolbar off screen
self.toolbar.frame = toolbarFrame;
}
completion:^(BOOL finished)
{
self.toolbar.hidden = YES;
}];
Here is the Code:
[UIView beginAnimations:#"hideView" context:nil];
[UIView setAnimationDuration:0.7];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationTransition:UIViewAnimationTransitionNone forView:toolBar cache:YES];
toolbarFrame.origin.y = 380;
toolBar.frame = toolbarFrame;
[UIView commitAnimations];
you can modify the toolBar 'y' origin.

I added a view (displayTapeView)to the superview via Storyboard and it's working fine. But when I want to remove displayTapeView when clicking the "Back"button on the displayTapeView. It doesn't work. My current code is as below:
- (IBAction)tapeButtonPressed:(id)sender {
self.displayTapeView.hidden=NO;
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:1.0];
//[[self displayTapeView] removeFromSuperview];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.displayTapeView cache:YES];
self.displayTapeView.layer.masksToBounds=NO;
self.displayTapeView.layer.shadowOffset=CGSizeMake(-15.0,20.0);
self.displayTapeView.layer.shadowRadius=5.0;
self.displayTapeView.layer.shadowOpacity=0.5;
//[[self view] addSubview:_displayTapeView];
[UIView commitAnimations];
}
- (IBAction)backButtonPressed:(id)sender {
[[self displayTapeView] removeFromSuperview];
}
What I want to do is when "Back" button is clicked, the displayTapeView is removed and the superview is shown.
Thank you in advance!
self.displayTapeView.hidden = YES;
I am new in ios development, Now i am doing some animation on my application.In my application has one menu on the bottom of main view and have two button one for hide the menu and other for show the menu .My needs is the show and hide function of menu is working like
the [self presentModalViewController:menuView animated:YES]; and [self dismissModalViewControllerAnimated:YES]; function(ie. click the show button ,pop the menuView from the bottom of main view and click the hide button ,move down the menuView ) . I know the basic animation like:
[UIView beginAnimations:#"ShowHideView" context:nil];
[UIView setAnimationCurve:UIViewAnimationOptionOverrideInheritedCurve];
[UIView setAnimationDuration:1.0];
[UIView setAnimationDelegate:self];
[menuView setAlpha:0];
[UIView commitAnimations];
If any body know ,please help me.
When you tap showMenuView, do as following,
- (IBAction)showView:(id)sender
{
[self.view addSubview: menuView];
CGRect rect = menuView.frame;
rect.origin.y = 480;
menuView.frame = rect;
[UIView beginAnimations:#"ShowView" context:nil];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationDuration:0.5];
rect.origin.y = 0;
menuView.frame = rect;
[UIView commitAnimations];
}
And to hide,
- (IBAction)hideView:(id)sender
{
CGRect rect = menuView.frame;
[UIView beginAnimations:#"HideView" context:nil];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationDuration:0.5];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:#selector(animationDidStop:finished:context:)];
rect.origin.y = 480;
menuView.frame = rect;
[UIView commitAnimations];
}
- (void)animationDidStop:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context
{
[menuView removeFromSuperview];
}
I started trying to recreate the buy button from the app store which requires a 2-stage click to buy something. I to animate the button expanding. So far I have this
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.75];
sender.autoresizesSubviews = NO;
sender.clipsToBounds = NO;
sender.frame = CGRectMake(63,326,200,37);
[UIView commitAnimations];
which just causes the button to become larger, it doesn't animate at all. Have I done something wrong or has anyone else implemented this type of button behaviour?
EDIT:
- (IBAction) buyButtonAction: (UIButton *) sender {
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1.5];
[UIView setAnimationDelay:0.5];
[UIView setAnimationCurve:UIViewAnimationCurveEaseIn];
sender.clipsToBounds = NO;
sender.frame = CGRectMake( CGRectGetMinX( sender.frame) - 30, CGRectGetMinY(sender.frame), 200, 37);
[sender setTitle:#"Touched Touched Touched" forState:UIControlStateNormal];
[UIView commitAnimations];
}
Are you targeting an iOS that doesn't support Blocks?
I've implemented a "button animates on touch" using the following nauseatingly simple code.
[UIView animateWithDuration:0.5 animations:^{
self.navigationItem.rightBarButtonItem.title = #"Quoting...";
}];
Alternatively, this code seems to work as well to animate a button on touch, if you can't support blocks (it also includes the blocks commented out if you go that route):
-(IBAction) clicked:(UIButton*)sender{
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.5];
[UIView setAnimationDelay:0];
[UIView setAnimationCurve:UIViewAnimationCurveEaseIn];
//[UIView animateWithDuration:2.5 animations:^{
sender.autoresizesSubviews = NO;
sender.clipsToBounds = NO;
sender.frame = CGRectMake(63,326,200,37);
//sender.frame = CGRectMake( CGRectGetMinX( self.theButton.frame) - 100, CGRectGetMinY(self.theButton.frame), 300, 40);
//[sender setTitle:#"Touched Touched Touched" forState:UIControlStateNormal];
//}];
SignView *tempVC = [[SignView alloc] initWithNibName:#"SignView" bundle:Nil];
[UIView beginAnimations:nil context:nil];
[UIView setAnimationTransition: UIViewAnimationTransitionCurlUp forView:self.view cache:YES];
[UIView setAnimationDelay:0.5f];
[UIView setAnimationDuration:2.0f];
[UIView commitAnimations];
[self presentModalViewController:tempVC animated:YES];
[tempVC passDataWithString:button2.titleLabel.text andColor:currentlySelectedColor isNightModeOn:nightMode.on];
The view slides up instead of Curling up.
What am I doing wrong?
To set the transition style of a modal view controller, set it's modalTransitionStyle property.
self.modalTransitionStyle = UIModalTransitionStylePartialCurl;
Also note that some transition styles don't look right on the simulator, but should be fine on the device.
Using OS 3.1 I'm placing a tap-detecting image view (taken from Apple's Scroll View suite samples) in a UIScrollView and want to zoom twice on the image view when it appears. The first zoom is to make the entire image visible and the second zoom is to zoom in to a specified region. What I have right now is:
- (void)viewDidLoad {
// After adding scroll view and image view
imageScrollView.minimumZoomScale = 0.5;
imageScrollView.maximumZoomScale = 2.75;
imageScrollView.zoomScale = 1.0;
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationDelegate: self];
[imageScrollView zoomToRect:[imageView frame] animated:YES];
[UIView commitAnimations];
and the following to detect the end of the first zoom and to trigger the second:
- (void)scrollViewDidEndZooming:(UIScrollView *)scrollView withView:(UIView *)view atScale:(float)scale {
selectedRect.origin.x = 60.0;
selectedRect.origin.y = 90.0;
selectedRect.size.width = 90.0;
selectedRect.size.height = 90.0;
imageScrollView.minimumZoomScale = 1.0;
imageScrollView.maximumZoomScale = 2.75;
imageScrollView.zoomScale = 2.5;
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationDelegate: self];
[imageScrollView zoomToRect:selectedRect animated:YES];
[UIView commitAnimations];
What happens is that this causes an infinite loop and the scroll view "wiggles" repeatedly between two zoomed-in points. What should I be doing differently? Thank you.
Surely you just need to check the current zoomScale as the first action in scrollViewDidEndZooming. If you are already zoomed in, don't do your new zoom.
