UILabel not showing text inside ScrollView for big Content - html

Question

My ScrollView's ContentView consists of just a UILabel which has leading space 8, trailing space 8, top space to container 8dp, and number lines set to 0. ScrollView ContentView height is to 9000.
I'm adding a big html content dynamically to the label..
public override void ViewDidLoad()
{
base.ViewDidLoad();
var attr = new NSAttributedStringDocumentAttributes();
var nsError = new NSError();
attr.DocumentType = NSDocumentType.HTML;
contentLabel.AttributedText = new NSAttributedString(GetContent(), attr, ref nsError);
contentLabel.Font = UIFont.FromName("Helvetica", 11f);
contentLabel.Layer.BorderWidth = 1f;
contentLabel.Layer.BorderColor = AZConstants.SeparatorColor.CGColor;
contentLabel.Layer.CornerRadius = 4f;
contentLabel.ClipsToBounds = true;
}
string GetContent()
{
var myHtmlText = "<h4 style=\"text-align: center;\">TERMS OF SERVICE AGREEMENT</h4>\n <p>\n " +

myHtmlText += ..... there are more characters in between, I can't add them all because of the character limit in stackoverflow
myHtmlText += "<p> " +

"alerts or other information from our Services concerning healthcare, treatment, devices, companies, stock " +
"quotes, investments or securities, please review the above Sections Warranty Disclaimers and Limitations of Liability again. In addition, for this " +
"</p>";
return myHtmlText;
}
Upto this everything works fine.
Now if I add just one word to myHtmlText, (In addition, for this particalur "</p>") the label text becomes invisible. Though the label border is visible. Is there some maximum content size? I couldn't find anything about it when I searched.
What am I doing wrong here? Any help is appreciated...

Answer 1

You need to use UITextView with scrolling enabled and editable/selected disabled (instead of UIScrollView & Content view & UILabel).
