Selecting and Unlocking Levels - Learn SpriteBuilder for iOS Game Development - page 273

Note A bundle , which is sometimes called a package , is just a folder structure
that OS X and iOS treat like a single file. Every app is a bundle, and you can
peek inside its contents in OS X if you right-click an .app file and select Show
Package Contents .
You can see and browse the bundle files in Xcode: just locate the Resources group, and
you'll see a Published-iOS folder with a blue icon. That folder and all of its contents will
be added to the compiled app bundle as is. However, you shouldn't manually add files to
that folder or edit them because the Published-iOS and Published-Android folders are
managed by SpriteBuilder, meaning your changes may be lost when publishing the
SpriteBuilder project.
This loop is repeated until the first Level#.ccb file returns a path string that is nil , indic-
ating that the file couldn't be found. Because the level file that wasn't found was already
counted, the count variable is reduced by one just after the loop before returning the
value.
In order to use the levelCount method, edit the setHighestUnlockedLevel:
method and replace the first line with the one highlighted in Listing 8-21 .
Listing 8-21 . Assigning the levelCount result
-(void) setHighestUnlockedLevel:(int)level
{
int totalLevelCount = [self levelCount];
if (_currentLevel > 0 && _currentLevel <=
totalLevelCount)
{
[[NSUserDefaults standardUserDefaults]
setInteger:level
forKey:KeyForUnlockedLevel];
}
}
