SDWebImage4.0之后加载gif不显示的解决方案

SDWebImage4.0之前

     UIImageView *imgView = [UIImageView new];
     imgView.contentMode = UIViewContentModeScaleAspectFit;
     imgView.frame = CGRectMake(, , , );

     NSString  *filePath = [[NSBundle bundleWithPath:[[NSBundle mainBundle] bundlePath]]pathForResource:@"going" ofType:@"gif"];
     NSData  *imageData = [NSData dataWithContentsOfFile:filePath];
     imgView.backgroundColor = [UIColor clearColor];
     imgView.image = [UIImage sd_animatedGIFWithData:imageData];
     [self addSubview:imgView];

SDWebImage4.0之后

     FLAnimatedImageView *imgView = [FLAnimatedImageView new];
     imgView.contentMode = UIViewContentModeScaleAspectFit;
     imgView.frame = CGRectMake(, , , );
     NSString  *filePath = [[NSBundle bundleWithPath:[[NSBundle mainBundle] bundlePath]]pathForResource:@"going" ofType:@"gif"];
     NSData  *imageData = [NSData dataWithContentsOfFile:filePath];
     imgView.backgroundColor = [UIColor clearColor];
     imgView.animatedImage = [FLAnimatedImage animatedImageWithGIFData:imageData];
     [self addSubview:imgView];
