Height of attributedText not returned - ios

Question

I need to display text in UITableViewCell and need to set the height of tableView. I am using the below methods to calculate the height of row dynamically. But the height is coming out to be a lot more than the actual height.
+ (CGFloat)getquestionLabelHeight:(NSNumber *)width text:(NSString *)text {
CGSize constraint = CGSizeMake([width floatValue], CGFLOAT_MAX);
NSStringDrawingContext *context = [[NSStringDrawingContext alloc] init];
CGSize boundingBox = [[ZUtility getAttributedText:text].string boundingRectWithSize:constraint options:NSStringDrawingUsesLineFragmentOrigin
attributes:#{NSFontAttributeName:[UIFont fontWithName:#"OpenSans" size:14]} context:context].size;
return boundingBox.height;
}
The reason I am converting text to attributed text is because normal text has html content and for line breaks '&nbsp' is present.
+(NSAttributedString *)getAttributedText:(NSString *)text {
NSMutableAttributedString *attrHTMLText = [[[NSAttributedString alloc] initWithData:[text dataUsingEncoding:NSUTF8StringEncoding] options:#{NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType,NSCharacterEncodingDocumentAttribute: #(NSUTF8StringEncoding)} documentAttributes:nil error:nil] mutableCopy];
[attrHTMLText addAttribute:NSFontAttributeName value:[UIFont fontWithName:#"OpenSans" size:14.0] range:NSMakeRange(0, attrHTMLText.length)];
[attrHTMLText addAttribute:NSForegroundColorAttributeName value:[UIColor blackColor] range:NSMakeRange(0, attrHTMLText.length)];
return attrHTMLText;
}
For width 343, height is coming out to be 915 which is not accurate.

You can use boundingRectWithSize
NSAttributedString *attrStr = [[NSAttributedString alloc]initWithString:#"<p>The HTML <strong><strong></strong> element defines <strong>strong</strong>text, with added semantic importance.</p>"];
// your attributed string
CGFloat width = 200; // whatever your desired width is
CGRect rect = [attrStr boundingRectWithSize:CGSizeMake(width, CGFLOAT_MAX) options:NSStringDrawingUsesLineFragmentOrigin | NSStringDrawingUsesFontLeading context:nil];;
NSLog(#"%#",NSStringFromCGRect(rect));
