I have a a tab bar that is made in the application delegate. By calling an action form a button click from one of the views loaded from the tab bar, I open the help screen but there is a jerking motion after loading.
forgive me for speaking informally..I have been picking my brain for the past few hours trying to figure this out..
-(void)flipToHelp {
HelpViewController *helpVariable = [[HelpViewController alloc] initWithNibName:#"HelpView" bundle:nil];
[self setHelpViewController:helpVariable];
[UIView beginAnimations:#"flipview" context:nil];
[UIView setAnimationDuration:0.5];
[UIView setAnimationCurve:UIViewAnimationCurveLinear];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft
forView:_window cache:YES];
[_window removeFromSuperview];
[helpVariable release];
self.window.rootViewController = self.HelpViewController;
[UIView commitAnimations];
}
Just to reiterate from the comment thread, you shouldn't be removing the window from its superview (it doesn't technically have a superview, so it's probably causing problems). And setting the window's rootViewController property should swap out the view hierarchies, Apparently the jerkiness comes from changing the window's rootViewController property, so maybe the solution is to avoid using that property. Here's what I think should be enough to accomplish this:
-(void)flipToHelp {
HelpViewController *helpVariable = [[HelpViewController alloc] initWithNibName:#"HelpView" bundle:nil];
[UIView beginAnimations:#"flipview" context:nil];
[UIView setAnimationDuration:0.5];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:_window cache:YES];
[self.tabBarController removeFromSuperview];
[_window addSubview:helpVariable];
[UIView commitAnimations];
}
-(void)flipToHelp {
HelpViewController *helpVariable = [[HelpViewController alloc] initWithNibName:#"HelpView" bundle:nil];
[self setHelpViewController:helpVariable];
[helpVariable release];
[UIView beginAnimations:#"flipview" context:nil];
[UIView setAnimationDuration:0.5];
[UIView setAnimationCurve:UIViewAnimationCurveLinear];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft
forView:self.window
cache:YES];
self.window.rootViewController = self.HelpViewController;
[UIView commitAnimations];
}
How about this code? Does it still have a jerky animation?

I have code:
ListViewController * listViewController = [[ListViewController alloc] initWithNibName:#"ListViewController" bundle:nil];
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1.5];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.view cache:YES];
[self viewWillDisappear:YES];
[listViewController viewWillAppear:YES];
self.view.hidden = YES;
listViewController.view.hidden = NO;
[self viewDidDisappear:YES];
[listViewController viewDidAppear:YES];
[UIView commitAnimations];
But it does not works, and listViewController does not displayed( Please, somebody can tell me the solution of this problem?
Try something like:
UIViewAnimationOptions ops = UIViewAnimationOptionTransitionFlipFromRight;
NSArray *temp = [[NSBundle mainBundle] loadNibNamed:#"NameOfNib" owner:self options:nil];
UIView* newView = [[temp objectAtIndex:0] view];
[UIView transitionFromView:self.view toView:newView duration:1.5 options:ops completion:nil];
self.view = newView; //Lets you control the new view from the current controller (you might want to save a reference to the old one if you need to change back)
As meronix said, non-block based animation is discouraged by Apple for the newer iOS versions. The above method is the "approved" way to do it.
Just so you know, the viewWillAppear, viewDidDisappear, and similar methods aren't methods that YOU call to make the view do things. They're called automatically when these things happen.
Your code had a few misunderstandings; I've commented on them below
//This looks fine (depending on what is in the nib)
ListViewController * listViewController = [[ListViewController alloc] initWithNibName:#"ListViewController" bundle:nil];
//Normally I use these to move things around, not change the view
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1.5];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.view cache:YES];
[self viewWillDisappear:YES]; //These two methods aren't things that you call
[listViewController viewWillAppear:YES];
self.view.hidden = YES; //If you're flipping or otherwise moving a view out of
listViewController.view.hidden = NO; //sight then you don't need to hide/unhide views
[self viewDidDisappear:YES]; //Same as above, you don't call these
[listViewController viewDidAppear:YES];
[UIView commitAnimations];
Remove unnecessary code and just write this ...
ListViewController * listViewController = [[ListViewController alloc] initWithNibName:#"ListViewController" bundle:nil];
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1.5];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.view cache:YES];
[self.view addSubview:listViewController.view];
[UIView commitAnimations];
it cannot work!
you just create and allocate a UIViewController, but never push it on any stacks, or add its view to a visible view.
when you set listViewController.view.hidden to no, you are not magically showing it on screen: you need to add its view to a view (or window) which is already on screen...
ps beginAnimation is deprecated: use blocks animation instead...
I am using such code to present a new view, I don't it's good or not. Currently the default animation is show the view from bottom up, but i want it to animate from right to left(fly in), is it possible to change the default animation type and how? Thanks.
[self presentModalViewController:navController animated:animated];
You can disable the slide-up animation like this:
[self presentModalViewController:navController animated:NO];
Then you can provide your own animation code:
navController.view.frame = CGRectMake(320, 0, navController.view.frame.size.width, navController.view.frame.size.height);
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.5];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
navController.view.frame = CGRectMake(0, 0, navController.view.frame.size.width, navController.view.frame.size.height);
[UIView commitAnimations];
This example gives you the "Fly-in" from right with a smooth speed-curve.
Another way is using the built in slide-in from right with navigationcontroller:
[self.navigationController pushViewController:navController animated:YES];
In this one, your top-viewcontroller needs to be a UINavigationController and it's rootcontroller needs to be your viewcontroller. Then you can push other viewcontrollers.
I have done this and its working for me try ths:
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.6];
[UIView setAnimationDelegate:self];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.View2.superview cache:YES];
[self.View2 removeFromSuperview];
[self performSelector:#selector(replaceViews2) withObject:nil afterDelay:0.6];
[UIView commitAnimations];
i am using following code , but subview is added below the the parentview not ON parent view(self.view)..any help please?
-(IBAction)okbutton:(id)sender
{
obj = [[imgViewNextController alloc] initWithNibName:#"green" bundle:nil];
obj.view.frame = self.view.frame;
[UIView beginAnimations:#"curldown" context:nil];
[UIView setAnimationDelegate:self];
[UIView setAnimationDuration:.5];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:self.view cache:YES];
[self.view addSubview:obj.view];
//[self.view insertSubview:obj.view aboveSubview:self.view];
[UIView commitAnimations];
Are you using a TableView ?
Some objects do (strange) things, so it may be related.
If possible give use more information about your self object.
By the way, you can try
[ self.view insertSubview: atIndex: ];
or
[ self.view insertSubview: aboveSubview: ];>
Good Luck !
I am flip animation to go from one view to another and animation is working properly but when i am using button action on that view that time application is getting crash.
Please help me out to solve this problem.
my code is:
Abtsk1 *secondViewController = [[Abtsk1 alloc]
initWithNibName:#"Abtsk1"
bundle:nil];
[UIView beginAnimations:#"flipping view" context:nil];
[UIView setAnimationDuration:1];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlDown
forView:[[self navigationController] view] cache:YES];
[self.view addSubview:secondViewController.view];
[UIView commitAnimations];
Thanks
Kunal
if i run following gives error,current controller is table controller....
SetController *aSecondView = [[SetController alloc] initWithNibName:#"Sets" bundle:nil];
SchedAppDelegate *mainDelegate = (SchedAppDelegate *)[[UIApplication sharedApplication] delegate];
[mainDelegate setSettingsViewController:aSecondView];
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:2.0];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:[[self view] superview] cache:YES];
[self.view removeFromSuperview];
[self presentModalViewController:aSecondView animated:NO];
//[aSecondView release];
[UIView commitAnimations];
It appears that mView is a UIViewController and not a UIView.
This is the proper way to apply a custom animation to a modal view controller:
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:2.0];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:[self view] cache:YES];
[self presentModalViewController:mView animated:NO];
[UIView commitAnimations];
If mView is a view controller, you can present it with a flip animation by doing the following:
mView.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentModalViewController:mView animated:YES];
The modalTransitionStyle property is only available for iPhone OS 3.0 onwards. Hope this helps. :)
