Removing %2520 and other nonstandard characters from URL in obj c

Question

I am getting a URL from server and trying to load the URL in webview. The issue is that the url which I am getting contains non standard characters. The URL is:

https//p-r3.test.abc.com:443%2Ftablet%2Fjsp%2Fgift%2Fipad%2Fgifter%2FgitGiftList.jsp%3FregId%3D74500002%26filterBy%3DviewAll%26pageId%3DourGifty%26sort%3Dcategory%26groupBy%3Dcategory%26view%3Dlist%26categoryId%3D%26addCat%3Dcat100540004&title=re%20-&imgurl=https%3A%2F%2Fm-r3-testy.tr.com%3A443%2Ftablet%2Fimages%2Ft_Full.jpg%3Fwid%3D300%26hei%3D300.

I need to remove characters like %2520, %2F, %3D and other non standard characters from the URL. Anyone has idea to remove this encoding.
Any help would be appreciated

Thanks

Solution 1

%2520 is simply a double-encoded space. Encode it once and you get %20, encode it twice and you get %2520. It's not "non-standard", it's just poorly coded. In theory, there's no reason why you can't just replace %2520 with a space, but for all I know the server-side code is expecting the double-encoded string.

Found the answer.I am removing the encoding using the built in function of iOS.abc = [def stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

and i am loading abc in webview.It is working fine. Thanks all for the responses.

You seem to have an urlencode() too many, or an urldecode() too few, in the code processing the URL server side.
