React-Native iOS14 图片不显示的解决方法

1. 在依赖包中找到文件：RCTUIImageViewAnimated.m
   　 路径：/node_modules/react-native/Libraries/Image

2.将RCTUIImageViewAnimated.m中的下面代码添加[super displayLayer:layer];

- (void)displayLayer:(CALayer *)layer
{
  if (_currentFrame) {
    layer.contentsScale = self.animatedImageScale;
    layer.contents = (__bridge id)_currentFrame.CGImage;
  }
}

修改为如下

- (void)displayLayer:(CALayer *)layer
{
  if (_currentFrame) {
    layer.contentsScale = self.animatedImageScale;
    layer.contents = (__bridge id)_currentFrame.CGImage;
  }else {
    [super displayLayer:layer];
  }
}
