Fortunately Apple Xcode team comes to rescue!
Xcode comes with a built-in feature to check whether your text strings have been localized or not. You do it by adding a runtime command line parameter (Xcode4):
Open top-left corner Scheme popup menu and select "Edit Scheme...". Choose Run scheme at left side table. Add "-NSShowNonLocalizedStrings YES" into "Arguments Passed On Launch". Add localized strings, recompile your app and run it.
[self.button setTitle:NSLocalizedString(@"KEY", @"comment") forState:UIControlStateNormal];There are few things to notice:
- Checks only NSLocalizedString strings. Search first for all @" and verify everything is localized.
- Checks only strings used at runtime. This is not a full codebase static analyzer.
- Works only with hardcoded string names. If you generate NSLocalizedString key dynamically, you will get "false" reports.
- Results are in console, search for " not found in strings table "
