What is the length in bytes of a NSString?

Question

How do I get the bytes length of NSString? if myString contains "hallo", myString.length will return 5, but how many actual bytes are taken?

Answer 1

NSString *test=@"ABCDEFGHIJKLMNOPQRSTUVWXYZ"; NSUInteger bytes = [test lengthOfBytesUsingEncoding:NSUTF8StringEncoding]; NSLog(@"%i bytes", bytes); 

Answer 2

To get the bytes use

NSData *bytes = [string dataUsingEncoding:NSUTF8StringEncoding]; 

Then you can check bytes.length

Number of bytes depend on the string encoding
