iOS : How to do proper URL encoding?

Question

I\'m unable to open a URL into UIWebView so I\'ve seached & found that I need to encode URL, so I tried to encode it but, I\'ve facing problem in URL encodi

Answer 1

The most straightforward way is to use:

NSString *encodedString = [rawString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

iDhaval was close, but he was doing it the other way around (decoding instead of encoding).

Anand's way would work, but you'll most likely have to replace more characters than spaces and new lines. See the reference here: http://en.wikipedia.org/wiki/Percent-encoding#Percent-encoding_reserved_characters

Hope that helps.
