while ((range = [str rangeOfString:@"<[^>]+>" options:NSRegularExpressionSearch]).location != NSNotFound)
    str = [str stringByReplacingCharactersInRange:range withString:@""];
return str;

Answer 2

NSAttributedString *str=[[NSAttributedString alloc] initWithData:[trimmedString dataUsingEncoding:NSUTF8StringEncoding] options:@{NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType, NSCharacterEncodingDocumentAttribute: [NSNumber numberWithInt:NSUTF8StringEncoding]} documentAttributes:nil error:nil];

Answer 3

If you want to get the content without the html tags from the web page (HTML document) , then use this code inside the UIWebViewDidfinishLoading delegate method.

  NSString *myText = [webView stringByEvaluatingJavaScriptFromString:@"document.documentElement.textContent"];

Answer 4

Here's the swift version :

func stripHTMLFromString(string: String) -> String {
  var copy = string
  while let range = copy.rangeOfString("<[^>]+>", options: .RegularExpressionSearch) {
    copy = copy.stringByReplacingCharactersInRange(range, withString: "")
  }
  copy = copy.stringByReplacingOccurrencesOfString("&nbsp;", withString: " ")
  copy = copy.stringByReplacingOccurrencesOfString("&amp;", withString: "&")
  return copy
}

Answer 5

following is the accepted answer, but instead of category, it is simple helper method with string passed into it. (thank you m.kocikowski)

-(NSString *) stringByStrippingHTML:(NSString*)originalString {
    NSRange r;
    NSString *s = [originalString copy];
    while ((r = [s rangeOfString:@"<[^>]+>" options:NSRegularExpressionSearch]).location != NSNotFound)
        s = [s stringByReplacingCharactersInRange:r withString:@""];
    return s;
}
