ios14里重写了displayLayer:方法会有问题，看了下，应该是这样改。最下边注释的是原来的，不知道正式版的苹果会不会修复这个问题。

- (void)displayLayer:(CALayer *)layer {
    UIImage *currentFrame = _curFrame;
    if (currentFrame) {
        layer.contentsScale = currentFrame.scale;
        layer.contents = (__bridge id)currentFrame.CGImage;
    } else {
        // If we have no animation frames, call super implementation. iOS 14+ UIImageView use this delegate method for rendering.
        if ([UIImageView instancesRespondToSelector:@selector(displayLayer:)]) {
           [super displayLayer:layer];
        }
    }
//    if (_curFrame) {
//        layer.contents = (__bridge id)_curFrame.CGImage;
//    }
}

没什么用啊？

YYAnimatedImageView *imageView = [[YYAnimatedImageView alloc] initWithImage:[YYImage imageNamed:@"voice"]];
imageView.frame = CGRectMake(100, 100, 50, 50);
[self.view addSubview:imageView];

这里的Voice 是Gif 图片只播放一下就暂停了但是在IOS14以下就可以循环播放

这和我说的不是一个问题啊……我说的是ios14beta上，YYImageView加载不出普通的图片，然后改了就可以加载出来了。
你这个问题，你再找找别的吧

ios14 有两个问题：
1 gif 只播放一遍无法重复播放

播放一遍的问题，可以看下 loopcount 的值

这里的Voice 是Gif 图片只播放一下就暂停了但是在IOS14以下就可以循环播放

Gif图循环次数为1，在iOS14系统上就只播放一次，让UI重新生成一下gif即可。

works well in iOS 15.3, great!

import YYImage

extension YYAnimatedImageView {
    override open func display(_ layer: CALayer) {
        let currentFrame = value(forKeyPath: "_curFrame") as? UIImage
        
        if currentFrame != nil {
            layer.contentsScale = currentFrame!.scale
            layer.contents = currentFrame!.cgImage
        } else {
            if UIImageView.instancesRespond(to: #selector(display(_:))) {
                super.display(layer)
            }
        }
    }
}

This is a swift 5.5 version extension, will fix this bug.
