I have a method to animate and reset the view which is given below.
-(void)animateToFocus:(BOOL)animate index:(NSInteger)index {
if (animate) {
[UIView beginAnimations:#"Scroll" context:nil];
[UIView setAnimationDuration:0.5];
[UIView setAnimationDelegate:self];
[UIView setAnimationsEnabled:YES];
self.view.frame = CGRectMake(0, -50*index, self.view.bounds.size.width, self.view.bounds.size.height);
[UIView commitAnimations];
} else {
[UIView beginAnimations:#"Scroll" context:nil];
[UIView setAnimationDuration:0.5];
[UIView setAnimationDelegate:self];
[UIView setAnimationsEnabled:YES];
self.view.frame = CGRectMake(0, 0, self.view.bounds.size.width, self.view.bounds.size.height);
[UIView commitAnimations];
}
}
When I pass YES and a tag in this method, it will animate to top and when I pass NO it will reset the view.
It works perfectly in IOS6.When i update to IOS 7, resetting done as:
It will not animate completeley and a black space appear in the bottom. Can u please help me to solve this?
I'm guessing that's a UITableView inside?
If so, you shouldn't be animating it's frame you should use:
– scrollToRowAtIndexPath:atScrollPosition:animated:
or:
– scrollToNearestSelectedRowAtScrollPosition:animated:

I am trying to do an animation where a UIView should come from top to bottom(or till mid of screen) when we toch on top of the screen and drag down.
Set your view frame, and then add these code in your button action or else.
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationDuration:1.0];
[yourView setFrame:CGRectMake(0, 250, 320, 100)];
[UIView commitAnimations];
set positions according to ur need
[UIView beginAnimations:#"DragView" context:nil];
[UIView setAnimationCurve:UIViewAnimationCurveLinear];
[UIView setAnimationDuration:0.5f];
self.dragView.frame = CGRectMake(newXPose, newYPose,width, height);
[UIView commitAnimations];
Modal view in iOS appears from bottom of the screen to top, and dismisses from top to bottom of the screen. I would like to know, is there any way i can revert the above and make the model view appear from top of the screen to bottom of it. Thus when it is dismissed it will animate from bottom to top.
Yes why not I think I can offer you a workaround :) ....
First Make a custom UIView and set its coordinates as
View.frame=CGRectMake(0, 0, 320, 0);
Then use Animations to move it from top to bottom and vice-versa like this:-
For making it appear use the following code:-
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationDuration:0.25];
View.frame = CGRectMake(0, 0, 320, 460);
[UIView commitAnimations];
For dismissing it use :-
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationDuration:0.25];
View.frame = CGRectMake(0, 0, 320, 0);
[UIView commitAnimations];
I am developing an iPhone application, where i need to move a first view controller slowly upward in animation and move to second view controller. I am thinking to use CoreAnimation for moving the first view controller slowly upward and push to next view controller. Could someone help on giving what are the classes/apis available to achieve this?
Thank you!
Try this,
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1.0];
[UIView setAnimationTransition:UIViewAnimationTransitionNone forView:yourfirstview cache:YES];
[UIView setAnimationDidStopSelector:#selector(remove_view)];
//change frame here
yourfirstview.frame =CGRectMake(0,-480,320,480);
[UIView commitAnimations];
-(void)remove_view
{
[yourfirstview removeFromSuperview];
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1.0];
[UIView setAnimationTransition:UIViewAnimationTransitionNone forView:yoursecondview cache:YES];
//change frame here
yoursecondview.frame =CGRectMake(0,0,320,480);
[UIView commitAnimations];
}
You can easily achieve this on a single view controller using multiple UIViews
As per Apple's documentation:
In iOS 4 and later, use the block-based animation methods.
So, in order to produce the intended results, using the following code.
UIView *mySecondView = [[UIView alloc] initWithFrame:CGRectMake(0, 480, 320, 480)];
[mySecondView setBackgroundColor:[UIColor redColor]];
[self.view addSubview:mySecondView];
[UIView animateWithDuration:2.0 delay:3.0 options:UIViewAnimationOptionCurveEaseInOut animations:^{
[mySecondView setTransform:CGAffineTransformMakeTranslation(0, -480)];
}completion:^(BOOL done){
}];
I am developing iOS game and need custom animation so I am using this method
CGRect basketTopFrame = mainScreenView.frame;
basketTopFrame.origin.x = 320;
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.5];
[UIView setAnimationDelay:.5];
[UIView setAnimationCurve:UIViewAnimationCurveEaseIn];
mainScreenView.frame = basketTopFrame;
[UIView commitAnimations];
in the .h file I have declared mainScreen like this
IBOutlet UIView *mainScreenView;
So in the IB I have put UIView in the view in the interface and hooked it up with mainScreenView
So in the mainViewScreen the view sometimes shows up sometimes doesn't (works on the 2nd try) however when I remove the animation code it works perfectly fine..I don't know what is happening any help would be appreciated thanks
edit
this is how I added the view
MainScreen *mainScreen = [[MainScreen alloc]initWithNibName:#"MainScreen" bundle:nil];
[mainScreenView addSubview:mainScreen.view];
I tried it in a sandbox project, and this worked for me:
- (IBAction)buttonTouched:(id)sender {
myView.transform = CGAffineTransformMakeTranslation(-320, 0);
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.5];
[UIView setAnimationDelay:.5];
[UIView setAnimationCurve:UIViewAnimationCurveEaseIn];
myView.transform = CGAffineTransformMakeTranslation(0,0);
[UIView commitAnimations];
}
Looks like you are trying to move something off screen. An easier way is to do this
[UIView beginAnimations:#"UIBase Hide" context:nil];
[UIView setAnimationDuration:0.5];
[UIView setAnimationDelay:.5];
[UIView setAnimationCurve:UIViewAnimationCurveEaseIn];
mainScreenView.transform = CGAffineTransformMakeTranslation(320,0); //slide view to the right.
[UIView commitAnimations];
note: using 320 on the Translation wont move the view to the 320th pixel of the screen rather it moves your view 320px to the right. So if your mainScreenView is at origin.x = 100. After this translation it is now at 420.
To move it back do
self.transform = CGAffineTransformIdentity;
I am wondering how I would go about animating a UIView's to a specific CGPoint. The following is what I have so far (which doesn't work in it's current state):
#define MOVE_ANIMATION_DURATION_SECONDS 2
NSValue *pointValue = [[NSValue valueWithCGPoint:point] retain];
[UIView beginAnimations:nil context:pointValue];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationDuration:MOVE_ANIMATION_DURATION_SECONDS];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:#selector(animationDidStop:finished:context:)];
[UIView commitAnimations];
Try:
#define MOVE_ANIMATION_DURATION_SECONDS 2
[UIView beginAnimations:nil context:pointValue];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationDuration:MOVE_ANIMATION_DURATION_SECONDS];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:#selector(animationDidStop:finished:context:)];
CGRect frame = myUIViewObject.frame;
frame.origin = point;
myUIViewObject.frame = frame;
[UIView commitAnimations];
After the begin, but before the commit, change the value on your UI View.
If you're targeting 10.5 or above, you can use Core Animation via the animator proxy added to NSView. Try
[[someView animator] setFrame: someNewFrame];
