Hi,

I have question regarding NSLocalizedString and passing it other strings for formatting.

For example, I want to do this:

NSString *message = NSLocalizedString(@"Are you sure you want to delete %d widgets", "dialog asking user if they want to delete x number of widgets), number;

But this gives a compile error. So how do I format my NSLocalizedString call so that the %d will be replaced with my number variable?

TIA,
Ian

A couple of things:
- You are missing a quotation mark before the closing parenthesis.
- Also, what does your localization file look like. I didn't think the key could include spaces.
- I don't think putting ,number at the end is correct. You may need to wrap that in an NSString constructor.

Oops, the quotes is just something I forgot to type into the forums.

My localizable.strings file looks like this:

/* dialog asking user if they want to delete x number of widgets*/
"Are you sure you want to delete %d widgets" = "Are you sure you want to delete %d widgets";

I think this what you want instead of NSLocalizedString:

localizedStringWithFormat - it's in the NSString class. Look it up here (or in your own docs):

Spaces are fine in the key, but I tend to avoid them, just so that I can keep my keys manageable AND so I can quickly see if I've screwed something up and my string isn't being looked up properly.

Use NSLocalizedString like this:

Code:
NSString *myString = NSLocalizedString(@"deleteWidgets", nil);
myString = [NSString stringWithFormat: myString, number];

The first line fetches the string from LocalizableStrings that corresponds to the key "deleteWidgets". This string should be "Are you sure you want to delete %d widgets". The second line sticks the value of "number" into the spot where %d was and reassigns the result to myString. NSLocalizedString returns an autoreleased string, so nothing is leaking anywhere.

You wouldn't use localizedStringWithFormat for this necessarily - localizedStringWithFormat is used when you want to use stringWithFormat and have localization options applied to the substitutions. It's not used to look a string up from your Localizable.strings file.

Thanks smeger. Works great.
