笔记篇章 适配iOS 14 'HXPhotoPicker',

问题一：安卓上传的 webp 图片，无法显示

问题二：适配iOS 14 'HXPhotoPicker', '2.4.2'

问题一：

关于安卓上传的 webp 图片，无法显示，
我的版本 pod 'HXPhotoPicker', '2.4.2'#3.0.3, (2.4.2 pod 'SDWebImage','~> 4.2.2')
我的解决版本是：

#YYWebImage支持webp格式的图片
pod 'YYImage/WebP'

代码：

YYWebImageManager *manager = [YYWebImageManager sharedManager];
NSString *key = [manager cacheKeyForURL:[NSURL URLWithString:imageModels.picture]];
YYImageCache *cache = [YYImageCache sharedCache];
UIImage *image = [cache getImageForKey:key];
if (image) {

} else {

[[YYWebImageManager sharedManager] requestImageWithURL:[NSURL URLWithString:地址] options:YYWebImageOptionAvoidSetImage progress:^(NSInteger receivedSize, NSInteger expectedSize) {
} transform:^UIImage * _Nullable(UIImage * _Nonnull image, NSURL * _Nonnull url) {
return image;
} completion:^(UIImage * _Nullable image, NSURL * _Nonnull url, YYWebImageFromType from, YYWebImageStage stage, NSError * _Nullable error) {
nslog(@"%@", image);
if (!error) { 

}

}

问题二：

iOS 14 以下版本
pod 'HXPhotoPicker', '2.4.2'#3.0.3, (2.4.2 pod 'SDWebImage','~> 4.2.2')
图层 来看 YYAnimatedImageView
当我iOS 14 以上（含）
pod 'HXPhotoPicker', '3.0.3'#2.4.2, (3.0.3 pod 'SDWebImage','~> 5.0.0')
图层 来看 SDAnimatedImageView

图片展示不出来，

解决方法，在 YYAnimatedImageView 的 - (void)displayLayer:(CALayer *)layer 方法 里 适配了一下 iOS 14 ，

- (void)displayLayer:(CALayer *)layer {
  if (_curFrame) {
     layer.contents = (__bridge id)_curFrame.CGImage;
  } else {
    if (@available(iOS 14.0, *)) {
        [super displayLayer:layer];
    }
  }
}
