NSUTF8StringEncoding Target

Question

NSData *responseData = [NSURLConnection sendSynchronousRequest:theRequest returningResponse:&response error:&error]; NSString *data = [[NSString alloc] initWithData:urlData encoding:NSUTF8StringEncoding]; 

Could you explain the purpose of NSUTF8StringEncoding to me, does it encode all the data? Can you give an example of NSUTF8StringEncoding with input and output?

Answer 1

You must specify NSString using an encoding that NSData bytes can be interpreted as a valid string. However, it will not change / convert your string between encodings. If the NSData object contains a sequence of bytes that is not valid in UTF-8, it will simply return zero.
