Posted by Samuel in iPhone on April 8, 2009

If you are n00b when it comes to iPhone development, then you’ve come to the right place! We’ll be posting howtos, tips and tricks continuously.

So, how do you URL enconde a string? It’s quite simple if you know how. :)

+ (NSString *)urlEncodeValue:(NSString *)str
{
NSString *result = (NSString *) CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault, (CFStringRef)str, NULL, CFSTR(”:/?#[]@!$&’()*+,;=”), kCFStringEncodingUTF8);
return [result autorelease];
}

To create an URL object, do like this:

[NSURL URLWithString:encodedUrlString]
