iOS14系统YBImageBrowser显示图片黑屏问题

YYAnimatedImageView.

出现原因：

iOS 14系统调⽤⽅法- (void)displayLayer:(CALayer *)layer，YYAnimatedImageView没有正确处理

解决⽅法：

重写YYAnimatedImageView.m 的中的displayLayer⽅法⼤概在529 ⾏

方法一

 if(_curFrame) {

        layer.contents= (__bridgeid)_curFrame.CGImage;

    }else{

       // If we have no animation frames, call super implementation. iOS 14+ UIImageView use this delegate method for rendering.

       if([UIImageViewinstancesRespondToSelector:@selector(displayLayer:)]) {

            [superdisplayLayer:layer];

        }

    }

方法二

-(void)displayLayer:(CALayer*)layer{

  UIImage*currentFrame=_curFrame;

 if(!currentFrame){

        currentFrame=self.image;

   }

 if(currentFrame){

        layer.contentsScale=currentFrame.scale;

        layer.contents=(__bridge id)currentFrame.CGImage;

   }

}
