How to URL-encode/decode Strings (NSString) in Objective-C (iOS)[转载]

Here’s a short snippet how to encode a string to a URL compatible string.

Don’t forget to decode it on the responder’s side.

- (NSString*)encodeString:(NSString*)string
{
NSString *encodedString = [string stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]

return encodedString;
}

The same with decoding:

- (NSString*)decodeString:(NSString*)string
{
NSString *decodedString = [string stringByRemovingPercentEncoding]
return decodedString;
}

Happy Coding!
