Question

I’m pretty experienced with the syntax of Objective-C, but am lacking in how the object parts of it work (yes I know, it’s not good). I would like to know a few things:

1. How to create an object.
2. How to make it inherit certain properties from other classes (i.e. UIView).
3. How to make your own properties inside them (i.e. Health, Damage, Stamina).

If someone can please help me out, I would greatly appreciate it.

Answer 1

Some examples to look at before reading the documentation already posted:
To instantiate a class:

SomeClass *instantOfSomeClass = [[SomeClass alloc] init];

To inherit properties you would subclass it. To add custom properties, specify them in your subclass.

@interface SomeClassThatExtendsUIView : UIView
@property NSInteger health;
@property NSInteger damage;
@property NSInteger stamina;
@end

@implementation SomeClassThatExtendsUIView
// if not using auto synthesize
@synthesize health = _health;
@synthesize damage = _damage;
@synthesize stamina = _stamina;
@end
