Answer 1

That is pretty simple, you just need to add an extra format string modifier and add the variable in the correct place in your stringWithFormat: like so (where albumName is the name of your album`):

NSString *formatString = NSLocalizedString(@"%@ %1$i of %2$i", @"Picture X out of Y total.");
NSString *countTitle = [NSString stringWithFormat:formatString, albumName, currentIndex_ + 1, photoCount_,  nil];
[self setTitle:countTitle];

Also just to note, instead of using %1$i and %1$i for integers, you can just use %d for C Integers in your format string like so:

NSString *formatString = NSLocalizedString(@"%@ %d of %d", @"Picture X out of Y total.");
NSString *countTitle = [NSString stringWithFormat:formatString, albumName, currentIndex_ + 1, photoCount_,  nil];
[self setTitle:countTitle];
