To implement our World class, we need to use the following steps:
Add a new Objective-C class called
World, which is derived fromNSObject.To add a
levelproperty from theinttype, do the following:Add a static variable called
levelinWorld.h, as shown in the following line of code:static int level;
Add a static getter with the same name that returns the static variable, as shown in the following line of code:
+(int) level;
Add a static setter (
setLevel) that sets the static variable, as shown in the following line of code:+(void) setLevel:(int)value;
Repeat step 2 for the properties
gold,hitpoints, anddamage.We also need a
levelMaxproperty, but this one does not have a setter.We need to import the
Assets.hfile inside theWorld.mfile.Add a static
resetmethod that needs to be declared inWorld.h. It should look like the following piece of code:+(void) reset { level = 1; levelMax = 3; gold = 200; damage = [(NSNumber *) [Assets dictionaryFromJSON...
