SDWebimage加载GIF图片不动

SDWebimage 在4.0版本之前，调用如下的方法可以直接展示GIF的图片

- (void)sd_setImageWithURL:(nullable NSURL *)url
          placeholderImage:(nullable UIImage *)placeholder
                   options:(SDWebImageOptions)options
                 completed:(nullable SDExternalCompletionBlock)completedBlock;

但是4.0版本之后就不行了，因为SDWebimage新加入了FLAnimatedImageView这个类
直接用FLAnimatedImageView创建一个imageview 然后再调用之前的方法就可以了

具体的实现步骤：

pod导入下面的库
pod 'SDWebImage/GIF'

创建imageView

.h文件
//倒入头文件
#import <SDWebImage/FLAnimatedImageView+WebCache.h>

@interface LSLaunchView : UIView
@property (nonatomic, weak) FLAnimatedImageView *adImageView;
@end
.m文件
- (void)addAdImageView
{
    FLAnimatedImageView *imageView = [[FLAnimatedImageView alloc]initWithFrame:CGRectMake(0, 0, 100, 100)];
    [self addSubview:imageView];
    //下面方法二选一 根据自己的需求
    //带占位图的方法
    NSURL *url = [NSURL URLWithString:(NSString *)object.strIcon];
    [imageView sd_setImageWithURL:url placeholderImage:[UIImage imageNamed:@"icon_placeholder"]];
    //带block的方法
    [_launchView.adImageView  sd_setImageWithURL:url placeholderImage:nil options:SDWebImageRetryFailed completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, NSURL *imageURL) {
        //
        NSLog(@"实现一些方法");
    } ];
}

加载本地GIF

    NSString *filePath = [[NSBundle bundleWithPath:[[NSBundle mainBundle] bundlePath]] pathForResource:@"图片名称.gif" ofType:nil];
    NSData *imageData = [NSData dataWithContentsOfFile: filePath];
    UIImageView *adImage = [[UIImageView alloc] initWithFrame:CGRectMake(10, 10, (BXScreenW-30)/2, BXScreenH/2-20)];
    adImage.image = [UIImage sd_animatedGIFWithData: imageData];
    [self.view addSubview: adImage];

备注：

还有一种方式 就是将pod 库的SDWebImage回退到4.0之前的版本

pod 'SDWebImage','3.8.2'
