Transition of Modal View in ios - iphone

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];

UIView Animation not working properly in IOS 7

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:

How to make an UIView come top to bottom and vice versa on drag

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];

UIView shows the subview view sometimes?

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;

Animate two views like when you pass a phone call

I have made many tries to have the same effect of switch than the one you can see when calling a phone number : the front view disapear with a zoom effect, while the other one appears also with a zoom effect.
I can't achieve doing that effect, it's always a so-so. There seems to have a scale effect, with an action on opacity, but...
Do you know how this can be done to reflect that effect (not a so-so, I have tons of those) ?
// Make this interesting.
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:2.0];
[UIView setAnimationTransition:UIViewAnimationTransitionNone forView:self.view cache:YES];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:#selector(startupAnimationDone:finished:context:)];
self.view.alpha = 0.0;
self.view.frame = CGRectMake(self.view.center.x,self.view.center.y , 0, 0);
[UIView commitAnimations];
}
I hope this is a framework for a better animation. It's not guaranteed to work, but it's the best I could think of for the first part of the transition.
This will change the frame of your view controller's view so that it "sucks" itself into the center of the screen, which is a natural black color. Now that I think about it, a CGAffineTransform would have been much easier...
EDIT (For pedantry's sake): Starting with iOS 4, you can now use the newer, and much more syntactically clean, animation blocks and a nice transform:
[UIView animateWithDuration:0.25 delay:0.0 options:0 animations:^{
//animate the toolbars in from the top and bottom
[myTopView setFrame:CGRectMake(0, self.view.frame.size.height - 44, self.view.frame.size.width, 44)];
[myBottomView setFrame:CGRectMake(0, 0, self.view.frame.size.width, 44)];
//fade to black...
self.view.alpha = 0.0;
//and suck inwards.
self.view.frame = CGRectMake(self.view.center.x,self.view.center.y , 0, 0);
}
completion:^{
//do something to end nicely, or start another animation block.
}];

iPhone xCode | Slide a UIView

How can I make a transition from a UIView to other, like a slide from left or right ?
In addition to PageControl, refer ScrollViewSuite, Scrolling and PhotoScroller. Read the developer documentation for UIScrollView, you wouldn't have had to ask this question.
Write something like this.
[UIView beginAnimations:#"" context:NULL];
//The new position for view1
[myview1 setFrame: CGRectMake(0,0,320,100)];
//The new position for view2
[myview2 setFrame: CGRectMake(320, 0, 320, 100)];
//The animation duration
[UIView setAnimationDuration:2.0];
[UIView setAnimationDelay: UIViewAnimationCurveEaseIn];
[UIView commitAnimations];
