路径react-native/Libraries/Image/RCTUIImageViewAnimated.m下
if(_currentFrame) { layer.contentsScale= self.animatedImageScale; layer.contents= (__bridgeid)_currentFrame.CGImage; }
修改成：
if(_currentFrame) { layer.contentsScale= self.animatedImageScale; layer.contents= (__bridgeid)_currentFrame.CGImage; }else{ [superdisplayLayer:layer]; }
