Versuchen,

ZSSMessagesAvatarImage *avatarImage = [self.avatars objectForKey:message.senderId]; 
if (avatarImage.url) { 

    [cell.avatarImageView setImageWithURLRequest:[NSURLRequest requestWithURL:avatarImage.url] placeholderImage:nil success:^(NSURLRequest *request, NSHTTPURLResponse *response, UIImage *image) { 

     cell.avatarImageView.image = image; 

    } failure:nil]; 

} 
cell.avatarImageView.clipsToBounds = YES; 
cell.avatarImageView.layer.cornerRadius = 22; 
cell.avatarImageView.hidden = NO;

if(object[PF_CHAT_PICTURE]) 
{ 
UIImageView *imageView = [[UIImageView alloc] init]; 
NSString *imgUrl = [object[PF_CHAT_PICTURE] valueForKey:@"url"]; 

UIImage *image = [[SDImageCache sharedImageCache] imageFromDiskCacheForKey:imgUrl]; 
if(image == nil) 
{ 
    NSURL *imageUrl = [NSURL URLWithString:imgUrl]; 

    [imageView setImageWithURL:imageUrl completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType) 
    { 
     JSQPhotoMediaItem *mediaItem = [[JSQPhotoMediaItem alloc] initWithImage:image]; 
     JSQMessage *message = [[JSQMessage alloc] initWithSenderId:user.objectId senderDisplayName:user[PF_USER_FULLNAME] date:object.createdAt media:mediaItem];

Lösung auf Swift 4

Sie können Bibliothek "SDWebImage" verwenden

Schreiben Sie an die Methode:
func Kollektion (_ Collection: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell

cell.avatarImageView.sd_setImage(with: URL(string: "YOUR_URL")) 
cell.avatarImageView.sd_setShowActivityIndicatorView(true)
