سلام.
فایل react-native/Libraries/Image/RCTGIFImageDecoder.m رو بصورت زیر ویرایش کنید
CAKeyframeAnimation *animation = [CAKeyframeAnimation animationWithKeyPath:@”contents”];
…
animation.repeatCount = loopCount == 0 ? 0 : loopCount; // <-- fix for single play gif from joshbedo
animation.fillMode = @"forwards"; // <-- insert this line to prevent the image disappearing after animation
