How to debug CUICatalog: Invalid asset name supplied: (null)

问题

I am using xib to make UI of one of my apps. I am getting several warnings in console related to "CUICatalog: Invalid asset name supplied: (null)". From research I got to know that if we supply wrong image name in xib this error occurs. But here I want to know if there is any way to point the place from where its throwing that error, xib name or wrong image name etc.

回答1:

I have just fixed this error. Just Check the usage of function [UIImage imageNamed:(NSString*) imageName]. If the imageName is nil, then error happens.

In my code:

UIImageView*imageView=[[UIImageView alloc]initWithFrame:frame];

    if (imageName!=nil) {
        imageView.image=[UIImage imageNamed:imageName];
    }
