Error with a NSLocalizedString with parameter

I have to print a localized string passing it a parameter.

I use:

 NSString *myMsg = [[NSString alloc] 
   stringByAppendingFormat:NSLocalizedString(@"MyKey", @""), aString];
 [MyViewController updateMyMessage:myMsg];
 [myMsg release];

In the Localizable.strings, I use: "MyKey" = "My message says: %@";

EDIT:

It works, using this code:

NSString *myMsg = [NSString stringWithFormat:NSLocalizedString(@"MyKey", @""), aString];
 [MyViewController updateMyMessage:myMsg];

However, I would to know what's the problem in the the former code.

Fran,

stringByAppendingFormat appends to an existing string. Since myMsg has not been initialized the first example doesn't work.

You can reference: http://developer.apple.com/library/mac/#documentation/Cocoa/Reference/Foundation/Classes/NSString_Class/Reference/NSString.html and make sure you are using a method for creating or initializing strings.

Hope that helps,

Ryan
