Usage

To run the example project, clone the repo, and run pod install from the Example directory first.

Just need to create a new object and set the delegate:

SALAttributedStringExtensions *attributedStringExtended = [[SALAttributedStringExtensions alloc] init];
attributedStringExtended.delegate = self;    
            
NSAttributedString *attrString = [attributedStringExtended attributedStringFromHTML:HTML limitingImageHeight:300];

Implementing the delegates:

#pragma mark - SALAttributedStringDelegate
- (UIImage *)imagePlaceholder
{
    return [UIImage imageNamed:@"your-image-placeholder-name"];
}
                      
- (void)textAttachmentDownloaded:(SALResizableTextAttachment *)textAttachment inRange:(NSRange)range
{
    // Just add the textAttachment on your textStorage
    [self.textView.textStorage addAttribute:NSAttachmentAttributeName value:textAttachment range:range];
}

Other options:

//Creating without passing a limit height
NSAttributedString *attrString = [attributedStringExtended attributedStringFromHTML:HTML];
                                
//Creating with a custom textAttachment background color
NSAttributedString *attrString = [attributedStringExtended attributedStringFromHTML:HTML withTextAttachmentBackgroundColor:[UIColor blackColor]];
