I have data in the form :

I have to decode this and display in a Webview/UILabel!

I have tried this - URL Decoding, but it isn't working for me

make it as a string and replace special characters with relevant characters to make Proper data. — nick, Mar 21 '17 at 06:41

Try to use the native `NSAttributedString` with `NSHTMLTextDocumentType` attribute. — Raptor, Mar 21 '17 at 06:59

Use this -

- (NSString *)URLDecode:(NSString *)htmlString
{
    NSString *decodedURL = [htmlString stringByReplacingOccurrencesOfString:@"+" withString:@" "];
    decodedURL = [decodedURL stringByRemovingPercentEncoding];
    return decodedURL;
}

Here you get the output as - <p><strong>e-AWB and e

Umm, could you please help out with one more issue? How do display this decoded data in webview ? – Akshay Yerneni Mar 21 '17 at 07:46
I was trying the same thing, no content is showing in the webview :/ – Akshay Yerneni Mar 21 '17 at 08:04
I was just trying out your solution. Umm, it still isn't displaying any data in the webview. What's the need of passing the URL - http://website.com ? – Akshay Yerneni Mar 21 '17 at 08:38
Okay. I've tried, still no go :/ Anyways, thanks for helping in html decoding ! I'll figure something out for data display. I'll update the answer as soon as I get it working – Akshay Yerneni Mar 21 '17 at 09:58
It worked with setting the baseURL to nil. The array which I had to show was showing empty, I corrected that and everything worked – Akshay Yerneni Mar 22 '17 at 08:32
