Dynamic Image
You may replace an element in animation file like this sample.

Download Sample File
You can download a sample file from SVGA-Samples to try.
Step
Load animation as usual.
// Setup a SVGAPlayer by yourself. SVGAParser *parser = [[SVGAParser alloc] init]; [parser parseWithURL:[NSURL URLWithString:@"https://github.com/yyued/SVGA-Samples/blob/master/kingset.svga?raw=true"] completionBlock:^(SVGAVideoEntity * _Nullable videoItem) { } failureBlock:nil];
Setup replacing UIImage.
[...aPlayer setImage:iconImage forKey:@"99"]; // or [...aPlayer setImageWithURL:[NSURL URLWithString: @"https://github.com/PonyCui/resources/blob/master/svga_replace_avatar.png?raw=true"] forKey:@"99"];
ImageKey
The imageKey is the name of png file, ask your designer tell you the file name.
For example, the layer png image file name is xxx.png, imageKey is xxx. File name should always use English name, do not use Chinese or Japanese etc.
