I have a UIViewController based app and I want to changes data on view with animation (handle touchesbegan, touchesmove, touchesended). All data I save in a base). For example, I have main screen, and when (touches ended) handles, I want to show other view.
Whatever i will be to do, screens could be rotate (to right or to left, if position changes more then 1/2 of width View, but if labels count number more then count of rows in my table, I want to set state at image 2.
Could you see right way to do animations? For example, I could to create my own class or use app delegate, but I not sure from what I must to start.
Use UIView's transitionsWithView method:
[UIView transitionWithView:containerView
duration:0.2
options:UIViewAnimationOptionTransitionFlipFromLeft
animations:^{ [fromView removeFromSuperview]; [containerView addSubview:toView]; }
completion:NULL];

I am trying to create a sliding menu (like the one in google maps app) in which menu screen should be shown or added as subview over the existing screen on tapping a button. While showing it, the sub view should be animated from left to right. I tried to animate while adding it as subview, but failed in doing so. Can any one suggest how to do it? (or) Can I do it using navigation controller?
Thanks in advance!!
You need to add the subview, and set it's frame out of the screen.(320,0,100,568 for example).
Of course it's better to use auto layout for that.
Add as subview:
[self.view addSubView:sideMenu];
When you want to show it, just change it's frame using animation block.
[UIView animateWithDuration:0.2 delay:0.1 options:UIViewAnimationOptionCurveEaseInOut animations:^{
sideMenu.frame = CGRectMake(220,0,100,568);
} completion:^(BOOL finished) {
}];
As I said, it's better to use auto layout and not setting frames. I did it only for the example.
I have a UIView "MainView" that initially appears as follows:
The gradient bar is part of MainView, the whitespace beneath is part of a Container View subview.
When the search button in top-right is tapped, I animate a searchBar from offscreen to be visible in the view:
I manage to do this by the following code:
CGRect currentViewFrame = self.view.bounds;
currentViewFrame.origin.y += searchViewHeight;
[UIView animateWithDuration:0.4
delay:0.0
usingSpringWithDamping:1.0
initialSpringVelocity:4.0
options:UIViewAnimationOptionCurveEaseInOut animations:^{
self.view.frame = currentViewFrame;
}
completion:^(BOOL finished)
{
}];
Visually, the result of this animation is perfect. The entire view shifts, and the searchBar is now on screen. However, the searchBar does not respond to interaction. Correct me if I'm wrong, but I expect this is because the MainView's frame no longer includes the screen area that the searchBar now occupies, so its effectively a gesture deadzone.
So this makes me think that instead of lazily animating the entire MainView down to accomodate the searchBar, I must instead individually translate all subviews of MainView one at a time. In this simple situation, that would not be a big problem, but I can envision a circumstance with tens of subviews making that completely unrealistic.
What is the best method to accomplish what I am trying to do? Is there a secret to animating entire views/subviews without having gesture deadzones? Thanks in advance!!
I have two UIImageView's, one that is a background that should scroll, and one an avatar that should move positions based on user input.
I'm able to move the avatar with no problem, and I'm able to scroll my background when necessary with:
CGRect oldPos = _fieldView.frame;
CGRect newPos = CGRectMake(oldPos.origin.x, oldPos.origin.y - 400, oldPos.size.width, oldPos.size.height);
[UIView animateWithDuration:5.0
delay:0.0
options: UIViewAnimationCurveEaseOut
animations:^{
[_fieldView setFrame:newPos];
}
completion:^(BOOL finished){
NSLog(#"Done with animation");
}];
However, when this _fieldview scrolls, my avatar on top of it scrolls with it. How can I move my background image without affecting the other images?
A few other settings that may affect this:
I've disabled AutoLayout
My background image mode is set to AspectFill
I'm using a storyboard with a single UIView
Thank you for any suggestions.
EDIT
The avatar, runnerView, is added as a subview of _fieldView, with
[_fieldView addSubview:_runnerView];
You want your background scroll image to not be a superview to your avatar, but sibling view instead.
(Not the best representation, not sure how to make it look better though)
-Main View
--Scroll view
--Avatar
i.e.
[self.view addSubview:backgroundView];
[self.view addSubview:avatarView];
not
-Main View
--Scroll view
---Avatar
i.e.
[backgroundView addSubview:avatarView];
[self.view addSubview:backgroundView];
If it is required to be a subview, then you will have to move the avatar view an equal and opposite amount so it will stay in the same relative location.
I want to make a UIView animate when it's being closed. I tried reading the following:
http://felipe.sabino.me/ios/2012/05/10/ios-uiview-transition-effects/
iPhone UIView Animation Best Practice
iOS UIView Animation CATransform3DMakeRotation confusion
However, I'd like to make it transition from the side of the screen, as per the image in the Google Chrome app.
Is there another animation that is set for this? I was not able to find it... I'm assuming it has to do with animateWithDuration or a CATransform...can somebody point me in the right direction for this?
[EDIT]
I used the below post for an answer as well as this post:
Setting a rotation transformation to a UIView or its layer doesn't seem to work?
I was able to add multiple animations as per below:
[UIView animateWithDuration: .2
delay: 0
options: (UIViewAnimationOptionCurveLinear | UIViewAnimationOptionAllowUserInteraction)
animations:^{self.view.center = CGPointMake(self.view.frame.origin.x * 3, self.view.frame.origin.y * 2), self.view.transform = CGAffineTransformMakeRotation(M_PI_4/2);}
completion:nil];
Previously I was not aware you can add multiple animations so easily. That adds rotation as well as the linear movement together.
Animate your view so it moves offscreen/shrinks/expands/fades, then do the actual removal when the animation ends.
You can do this by altering the properties of the view (position/size/offset) between a beginAnimations/commitAnimations block. UIKit will then animate these properties over the time specified.
E.g something like;
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.30f];
view.transform =
CGAffineTransformMakeTranslation(
view.frame.origin.x,
480.0f + (view.frame.size.height/2) // move the whole view offscreen
);
background.alpha = 0; // also fade to transparent
[UIView commitAnimations];
In the animation end notification you can then remove the view.
I've never run Chrome on iOS, so I have to try to guess what your screenshot is showing.
Does the animation go off the screen while shrinking and turning to one side?
And do you mean you want to animate a UIViewController, or a UIView? Are you closing a view controller?
If it's a view controller, how are you managing your view controllers? Are you using a navigation controller, or are you presenting a set of modal view controllers, or some other method?
I'm trying to slide my main view controller view to the right when the user taps a button. I use this code:
[UIView animateWithDuration:1
delay:0
options:UIViewAnimationOptionBeginFromCurrentState
animations:^(void){ self.view.left = 300; }
completion:nil];
The result is that view.frame.origin.x does not take into account device orientation. If the screen is landscape left, then setting x = 300 does not move the view to the right, it moves it down. I could do a big switch statement to change the relevant parameter depending on orientation but I feel like I've done this before without having to resort to such shenanigans. Am I missing something obvious?
I've tried with no options, no difference.
I'm using a category on UIView so that I don't have to type out the entire CGRectMake explicitly. The results are the same if I do it with the full CGRectMake statement.
I had the same issue. Animating the view's bounds instead of the view's frame (I am assuming this is what the category is doing) worked for me.
