Explicitly disabling UIView animation in iOS4+

Question

I have been reading that Apple recommends to use block-based animations instead of CATransaction

Before, I was using this code to disable animations:

[CATransaction begin];
[CATransaction setDisableActions: YES];
// !!! resize
[CATransaction commit];

Is there a new recommended method to do this, or is this still okay?

Solution 1

[UIView setAnimationsEnabled:NO];
//animate here
[UIView setAnimationsEnabled:YES];

Solution 2

For iOS 7 and above this can now be accomplished with:

[UIView performWithoutAnimation:^{
    // Changes we don't want animated here
    view.alpha = 0.0;
}];

Solution 3

Swift 3+

UIView.performWithoutAnimation {
            // Update UI that you don't want to animate
        }

Solution 4

For MonoTouch (C#) users, here is a helper class:

public class UIViewAnimations : IDisposable
{
    public UIViewAnimations(bool enabled)
    {
        _wasEnabled = UIView.AnimationsEnabled;
        UIView.AnimationsEnabled = enabled;
    }

    public void Dispose()
    {
        UIView.AnimationsEnabled = _wasEnabled;
    }

    bool _wasEnabled;
}

Example:

using (new UIViewAnimations(false))
    imageView.Frame = GetImageFrame();

Solution 5

// Disable animations
UIView.setAnimationsEnabled(false)

// ...
// VIEW CODE YOU DON'T WANT TO ANIMATE HERE
// ...

// Force view(s) to layout
yourView(s).layoutIfNeeded()

// Enable animations
UIView.setAnimationsEnabled(true)

The problem with using the UIView approach is that you cannot nest it like you can with CATransaction approach. So if you had a block of code that disabled animations and made a call to something else that disabled animations inside that block the animations would be reenabled before the end of your block.

easy way to fix that is to check what the state was, using areAnimationsEnabled and then restore it to that after you're done

Glad someone else found it useful. In gist form: gist.github.com/jfoshee/5008117

What can i do, if i need to disable animation for concrete view object? Not for all Views

[Prasad Devadiga]

@JoshuaWeinberg I am facing an issue when using this, could you please check this stackoverflow.com/questions/16806816/…

I still don't get the use-case for this. Why would I bother wrapping this in a block? Why not just say "view.alpha = 0.0;" and be done with it?

[Brentley Jones]

@GregMaletic Because sometimes the code being run is already part of an animation somewhere else in the call stack. This allows the update to not be animated.

[Greg Maletic]

Ah…so the idea is that this is wrapped by some other [UIView animate] call, and this is a little internal set-aside, so I can include things in that animate block that I don't want animated?

[Brentley Jones]

Correct. Sometimes you also get caught up in an animation by the system.
