feat(ios): optimize method loadImage:completed:

[Geor9eLau]

In the protocol of HippyImageViewCustomLoader, there is a method called loadImage:completed:. As an iOS developer, we usually use SDWebImage to implement this interface. The loadImage(_:completed:) method is implemented using the loadImage(with:options:progress:completed:) method provided by SDWebImageManager.

 [SDWebImageManager.sharedManager loadImageWithURL:url options:0 progress:nil completed:^(UIImage * _Nullable image, NSData * _Nullable data, NSError * _Nullable error, SDImageCacheType cacheType, BOOL finished, NSURL * _Nullable imageURL) { completedBlock(data, url, error,  !!cacheType); }];

However, this implementation encountered some exceptions in practical scenarios. When the loaded image is found in the memory cache, the image parameter in the callback of the SDWebImageManager method has a value, but the data parameter is empty. This causes the image to fail to load in the application.

Therefore, aligning the interface with SDWebImage and internally handling this scenario will make it more convenient for integrators to implement and avoid encountering the same issue as I did.
