Scenario:

I want to localize my app AllSync but I was taken by a little frustration.

Following this good guide you can see that there are two main way to localize your iOS (iPhone/iPad) app:

• localize strings using Localizable.strings
• localize single nib file creating one version for each

I want to localize my nib files in the same way of using Localizable.strings

A possible solution can be to externalize in code every text setting but is a tedious process and you can’t use the flexibility of xcode 4. The real solution I hope will be used by many of you is this:

The solution:

Create an extended version of iOS user control that automatically translates every single text

Simple to obtain: just see this extended UIButton

@interface UIButtonThemed : UIButton
@end

@implementation UIButtonThemed
- (id)initWithCoder:(NSCoder *)aDecoder {
    if ((self = [super initWithCoder:aDecoder]))
	{
        self.titleLabel.adjustsFontSizeToFitWidth = YES;
        NSString* text = NSLocalizedString(self.titleLabel.text, nil);
        [self setTitle:text forState:UIControlStateNormal];
        [self setTitle:text forState:UIControlStateHighlighted];
        [self setTitle:text forState:UIControlStateDisabled];
        [self setTitle:text forState:UIControlStateSelected];
	}
	return self;
}
@end

You can use it inside xcode 4 configuring the base class for your control:

"Sync" = "Sincronizza";
"Settings" = "Impostazioni";
"Help" = "Guida";
"Share" = "Condividi";
"Rate us" = "Votaci";
"Follow us" = "Seguici";
