NSString returning jibberish

Question

Totally lost with this one. Here's my code:

theColor = [NSString stringWithFormat:@"white"];
NSLog(@"%s", theColor);

Which is returing:

†t†å

I must be doing something stupid, but can not figure it out for the life of me.

Answer 1

Change your print to:

NSLog(@"%@", theColor);

Hope it helps.

The thing is that %s expects a C-string (char array with a NULL terminator) and you are passing a NSString instance which is not the same as a C-string. The modifier you need in a format to print NSString content is %@.

Answer 2

%s is for printing C-style strings.

%@ is for printing Objective-C objects (like NSString).

Answer 3

BTW: “theColor = [NSString stringWithFormat:@"white"];” – why not “theColor = @"white";”?
