[ios] Categorizing Assets

[doublejtoh]

I need to categorize ios image assets. I tried to categorize them by changing uri of each image assets.
e.g) 'assets-library://asset/asset.JPG?id=422A8321-E0FF-4DAB-9450-C6328A97AFF8&ext=JPG' -> 'assets-library://asset/asset.JPG?id=422A8321-E0FF-4DAB-9450-C6328A97AFF8_$(Category_Class_string)&ext=JPG'

But it seems this library has no API for this.
If there is proper API or other Library or other Methods for categorizing ios image assets, Let me know.

Thank you.
