How to change localized images at run time

I have created two localized directories named with en.lproj and fr.lproj. I put two different images with same name like.png in those localized directories.

Now i have created a table View Controller with two rows "English" and "French" text respectively.

After selecting first or second row i am fetching the bundle path and changing the whole localized text of my app at run time.

Code:

-(NSString*) languageSelectedStringForKey:(NSString*) key
{

    NSString *path;
    NSUserDefaults *userDefault = [NSUserDefaults standardUserDefaults];
    if([[userDefault valueForKey:@"language_Selected"] intValue] == 0)
      path = [[NSBundle mainBundle] pathForResource:@"en" ofType:@"lproj"];
    else if([[userDefault valueForKey:@"language_Selected"] intValue] == 1)
      path = [[NSBundle mainBundle] pathForResource:@"fr" ofType:@"lproj"];

    NSBundle* languageBundle = [NSBundle bundleWithPath:path];
    NSString* str=[[languageBundle localizedStringForKey:key value:@"" table:nil] retain];
    return str;
}

Through above code dynamically i can change the language of running app. But how to get images from that bundle?

Any Idea?

Thanks

Presumably, you don't want to change every image, only the images that contain text or other culture-dependent content. For these images, you could add an entry to the localizable.strings file that contains the image path for a give language, and use this path instead of a hard-coded path.

That said, in many cases you'll have images included in the UI as part of a .xib. All you need to do in these cases is localize the xib (i.e. make a different version of the .xib per language--you can do this in XCode through the Languages control in the properties panel) and simply change the image in each language version of the .xib using Interface Builder.
