Localizing strings with XCode 4.2 (IOS-IPhone dev) - iphone

Question

In some of my screens in my program the localized strings work and in some it doesn't.
(Xcode 4.2)
What I've done:
Added a Localizable.strings in the folder "Resources"
in my .h file, inside the #interface ClassViewController : UIViewController {} I added:
IBOutlet UILable *labelName;
Also in the .h file, I added
property (nonatomic, assign) IBOutlet UILabel *labelName;
In the .m file, I added :
#synthetize labelName;
Still in the .m file, I added inside "-(foid)dealloc" :
[labelName release];
In -(void)viewDidLoad I added :
self.labelName.text = [NSString stringWithFormat:#"KEY"];
Finally, in the xib file (with the Interface manager), I linked the label object with the variable.
So, as I said, this method works in some screen and not in others. Any idea?
Solution:
That what a stupid mistake. the line to enter the text should be:
NSLocalizedString(#"KEY", nil);

Answer 1

Use instead:
self.labelName.text = NSLocalizedString(#"KEY", "");
From the Documentation:
Name: NSLocalizedString
Description: NSString *NSLocalizedString(NSString *key, NSString *comment)
Availability: iOS (2.0 and later)
Abstract: Returns a localized version of a string.

Answer 2

As Vince pointed out, you need to use NSLocalizedString function. So in this case the code in 6 would be:
self.labelName.text = NSLocalizedString(#"The key for this label",#"Some comment");
That should work for you.

In XCode-4.2 you can do the following:
Click on "target"
Then select "Build Phase"
Select "Add Build Phase" & choose "Add Copy files".
After select "copy files(int item)".( where 'int' may be 1or 2 or 3 etc. depending upon how many items previously have been created).Set "Destination" to "Resources".
Now click on '+' & choose your created '.string' file(eg. localization.string).
It works, hope it will help you.

What do you imagine this line does?
self.labelName.text = [NSString stringWithFormat:#"KEY"];
Because it's functionally equivalent to writing this:
self.labelName.text = #"KEY";
But I suspect that what you meant to write was this instead:
self.labelName.text = NSLocalizedString(#"KEY", #"description");
