SpriteAtlas Late Binding with UGUI

[TheValar]

In order to properly use a SpriteAtlas with AssetBundles you need to register to the atlasRequested event from SpriteAtlasManager and provide the SpriteAtlas once you load it. I believe I am doing this correctly but just end up with all of my UI being white squares.

I’ve read elsewhere that UGUI Images do not support late binding but they none of those posts were recent and I’m hoping this has been fixed by now and I’m just missing something. Has anyone successfully done this for UGUI Images or know of a workaround?

Are you sure this is the case? i am not familiar with SpriteAtlasManager since it’s probably an addition to one of the more recent versions of Unity, but is this really the way you’re supposed to work with it?

In the past, if you packed sprites into an atlas, they would already be included in the asset bundle so you don’t have to do any manual resolving yourself.

Also, from the docs:

Trigger when any Sprite was bound to SpriteAtlas but couldn’t locate the atlas asset during runtime.
This usually means the sprite was packed to an atlas which is not included in build

I am not sure how can you get a scenario where a sprite was packed into an atlas but it wasn’t included in the build (or is that a feature of the new sprite atlas system?)

@TheValar have you find the solution?
I met the same problem and I find this because of async-loading cause the action callback outside of the atlasRequested. Is there any solution for ugui, or back to using the tag solution?

SpriteAtlasManager.atlasRequested is not invoked in editor

I am using AssetBundle in editor and use the new spriteatlas asset in 2017. But I met a problem, I need to use the spriteatlas and asset bundle both in editor, and I register the SpriteAtlasManager.atlasRequested. But it will not callback in editor, but it can be invoked in player. I test check or not check the "Include build", the result is the same. Is there anything I am missing?

Nope never found a solution for this Also have not heard anything about when this might be fixed. It kinda seems to me that Unity has abandoned UGUI for the time being

Anyone found any more information regarding Late binding with UGUI?

We are in a situation where late binding works correctly on our Android devices but we get white squares on iOS.

Any help would be immensely appreciated!

disable ugui gameobject when instanced, enable it in next frame

Thanks @liangpengcheng , however we are not instantiating our gameobjects but instead we are having them start in the scene and get their Image sprite from Late Binding from asset bundles
