So I have this:

  NSData *charlieSendData = [[charlieImputText stringValue] dataUsingEncoding:NSUTF8StringEncoding];

I know how to convert NSStrings to data but how I convert data back to a开发者_如何学Cn NSString?

You can use NSString's -initWithData:encoding: initializer method.

NSData *charlieSendData = [[charlieImputText stringValue] dataUsingEncoding:NSUTF8StringEncoding]
NSString *charlieSendString = [[NSString alloc] initWithData:charlieSendData encoding:NSUTF8StringEncoding];

Use NSString's initWithData method:

NSString *someString = [[NSString alloc] initWithData:charlieSendData encoding:NSUTF8StringEncoding];

That should do it.

Convert String to Data format

let data = string.data(using: .utf8)

Converting back from Data to string

 let str = String(data: data, encoding: String.Encoding.utf8) as String!

In Objective-c

NSString *string = [[NSString alloc] initWithData:dataToConvert encoding:NSUTF8StringEncoding];
