NSLog not working when I make a method call in objective c

Question

I'm working on my first ground-up iOS app. I'm sure I'm doing something wrong here, but I can't seem to ferret out the problem.

I have an app with some IBActions in it, which do two things:

1) Outputs some simple text via NSLog (to let me know the action worked) - this works okay (it outputs my text via NSLog)

2) Makes a call to a method in a custom class which should also output an NSLog statement. - this doesn't work (no text output via NSLog)

I'm also struggling a bit with where to create the instances of my classes so that they are accessible elsewhere in my code.

Here's the code:

//
//  ViewController.h
//  OrcAndPie
//
//  Created by me on 4/27/13.
//  Copyright (c) 2013 me. All rights reserved.
//

#import <UIKit/UIKit.h>
#import "Player.h"
#import "Orc.h"

@interface ViewController : UIViewController {
    // Variables that you want to access globally go here?
    Player *wizard;
    Orc *grunty;

}

-(IBAction)takePie:(id)sender;
-(IBAction)castFireball:(id)sender;
-(IBAction)attack:(id)sender;



@end

and

//
//  ViewController.m
//  OrcAndPie
//
//  Created by me on 4/27/13.
//  Copyright (c) 2013 me. All rights reserved.
//

#import "ViewController.h"
#import "Player.h"

@interface ViewController ()

@end

@implementation ViewController

-(IBAction)takePie:(id)sender{
    // Player attempts to take the pie
    // If Orc's health is > 0, don't let the player take the pie
    // If the Orc's health is <= zero, let the player take the pie
    NSLog(@"IBAction - player attempted to take the pie.");
    [wizard takePie];

}

-(IBAction)castFireball:(id)sender{
    NSLog(@"IBAction - player cast fireball.");
    [wizard castFireball];
}
-(IBAction)attack:(id)sender{
    NSLog(@"IBAction - player attacked.");
    [wizard attackOrc];

}

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    Player *wizard = [[Player alloc]init];
    Orc *grunty = [[Orc alloc]init];

}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

@end

and

//
//  Player.h
//  OrcAndPie
//
//  Created by me on 4/27/13.
//  Copyright (c) 2013 me. All rights reserved.
//

#import <Foundation/Foundation.h>

@interface Player : NSObject

@property int maxHealth;
@property int currentHealth;
@property int armorClass;
@property int meleeToHitModifier;


-(void)setHeathBar;
-(void)attackOrc;
-(void)castFireball;
-(void)takePie;


@end

and

//
//  Player.m
//  OrcAndPie
//
//  Created by me on 4/27/13.
//  Copyright (c) 2013 me. All rights reserved.
//

#import "Player.h"

@implementation Player

@synthesize maxHealth;
@synthesize currentHealth;
@synthesize armorClass;
@synthesize meleeToHitModifier;

-(void)setHealthBar {
    NSLog(@"Player health is 15");
    return;

}

-(void)attackOrc {
    // roll a d20
    // add the "to hit" modifier
    // compare the result to the orc's armor class
    NSLog(@"Player - Player attached the Orc");
    return;

}
-(void)castFireball{
    NSLog(@"Player - Player casts Fireball");
    return;

}
-(void)takePie{
    NSLog(@"Player - Player attempts to take pie");
    return;

}

@end

Note: I also have an Orc class defined, but it looks fairly identical to the player class shown.

Thanks in advance for the help!

Your ViewController.h (which you should call by some more distinctive name, FYI) should look like this:

//
//  ViewController.h
//  OrcAndPie
//
//  Created by me on 4/27/13.
//  Copyright (c) 2013 me. All rights reserved.
//

#import <UIKit/UIKit.h>
#import "Player.h"
#import "Orc.h"

@interface ViewController : UIViewController

@property Player *wizard;
@property Orc *grunty;

-(IBAction)takePie:(id)sender;
-(IBAction)castFireball:(id)sender;
-(IBAction)attack:(id)sender;

@end

Then in your ViewController.m, your viewDidLoadMethod should look like:

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    self.wizard = [[Player alloc]init];
    self.grunty = [[Orc alloc]init];

}

This should at least ensure you have an instantiated instance of Player that you can call methods on, so your NSLog should be reached.
