Objective-C Convert NSData to NSString

Question

Here are the code I tried to convert NSData to NSString but the program return "Program received signal:SIGABRT".

NSString *string= [NSString stringWithUTF8String:[data bytes]];

OR

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

Is there any other better way to do it?

Answer 1

Here's a highly up-voted answer that shows how to do it. In a nutshell:

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

The first idea looks like a fail because of sending [data bytes]. stringWithUTF8String isn't prepared for a void *. The second idea looks as if it should work, even with nil input.

Answer 2

Use this code

NSString* myString;
myString = [[NSString alloc] initWithData:nsdata encoding:NSASCIIStringEncoding];
