How-To: URL Encode NSString in Objective-C
Jan.21, 2009 in

It’s very easy to URL Encode an NSString in Objective-C (i.e. make a string safe to send using a GET request). Simply do this:
NSString* escapedUrlString =
[unescapedString stringByAddingPercentEscapesUsingEncoding:
NSASCIIStringEncoding];
Then just use the escapedUrlString in your NSURL object and you’re on your way.

If you’re a developer which lives outside the US, you have to deal most of the time with foreign characters etc. NSUTF8StringEncoding does the trick.

This actually doesn’t work. I tried it on a string containing a plus sign (+), and it did not convert it to %2B. Took me a while, but once I caught this, my application worked as expected. I’m looking for some other built in URL encoding, but in the mean time this table seems to be correct as to what needs to be replaced:

NSString * encodedString = (NSString *)CFURLCreateStringByAddingPercentEscapes(NULL,(CFStringRef)yourtext,NULL,(CFStringRef)@”!*’();:@&=+$,/?%#[]“,kCFStringEncodingUTF8 );
