iPhone：界面构建器中的NSLocalizedString？

Question

Is there any way to insert an NSLocalizedString in interface builder. For example set a label text to a localized string instead of a static string?

I really hate to create a property for every single item that requires a localized string.

Even if this post is old, for those interested in automatically localizing your IB files, check this out: https://github.com/angelolloqui/AGi18n

You can take advanced of the User Defined Runtime Attributes:

First define a new category for UILabel:

#import "UILabel+Localized.h"

@implementation UILabel (Localized)
-(void) setTextLocalized:(NSString *)aText{
     [self setText:NSLocalizedString(aText, nil)];
}
@end

Then in the interface builder, User Defined Runtime Attributes :

textLocalized String your string to localized

To avoid creating a bunch of categories, create just one that categorize the NSObject and then check for the isKindOfClass as suggested. See the code below:

#import "NSObject+Localized.h"

@implementation NSObject (Localized)

///
/// This method is used to translate strings in .xib files.
/// Using the "User Defined Runtime Attributes" set an entry like:
/// Key Path: textLocalized
/// Type: String
/// Value: {THE TRANSLATION KEY}
///
-(void) setTextLocalized:(NSString *)key
{
    if ([self isKindOfClass:[UILabel class]])
    {
        UILabel *label = (UILabel *)self;
        [label setText:NSLocalizedString(key, nil)];
    }
    else if ([self isKindOfClass:[UIButton class]])
    {
        UIButton *button = (UIButton *)self;
        [button setTitle:NSLocalizedString(key, nil) forState:UIControlStateNormal];
    }
    else if ([self isKindOfClass:[UIBarButtonItem class]])
    {
        UIBarButtonItem *button = (UIBarButtonItem *)self;
        [button setTitle:NSLocalizedString(key, nil)];
    }
}

@end

NSLocalizedString is not the recommended way to localize Interface Builder files. Check out ibtool :
