    <p>I am working on a scoreboard of sorts. The player can adjust three different values (gear, level, and bonuses) that when added should provide a total strength. Each of these values is currently being output as an integer and a UILabel displays its' respective integer. I cannot figure out how to add all three integers and then display them on a UILabel. I am currently developing for iOS 7 but I don't imagine this to be terribly different for current supported OS's. Any help is greatly appreciated. </p> <p>.h</p> <pre><code>#import &lt;UIKit/UIKit.h&gt; int levelCount; int gearCount; int oneShotCount; int totalScoreCount; @interface ViewController : UIViewController @property (weak, nonatomic) IBOutlet UILabel *totalScore; @property (weak, nonatomic) IBOutlet UILabel *playerName; @property (weak, nonatomic) IBOutlet UILabel *levelNumber; @property (weak, nonatomic) IBOutlet UILabel *gearNumber; @property (weak, nonatomic) IBOutlet UILabel *oneShotNumber; - (IBAction)levelUpButton:(id)sender; - (IBAction)levelDownButton:(id)sender; - (IBAction)gearUpButton:(id)sender; - (IBAction)gearDownButton:(id)sender; - (IBAction)oneShotUpButton:(id)sender; - (IBAction)oneShotDownButton:(id)sender; @end </code></pre> <p>.m</p> <pre><code>#import "ViewController.h" @interface ViewController () @end @implementation ViewController - (void)viewDidLoad { [super viewDidLoad]; int ans = levelCount + gearCount + oneShotCount; self.levelNumber.text = [NSString stringWithFormat:@"%i", ans]; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; // Dispose of any resources that can be recreated. } - (IBAction)levelUpButton:(id)sender { levelCount = levelCount + 1; self.levelNumber.text = [NSString stringWithFormat:@"%i", levelCount]; } - (IBAction)levelDownButton:(id)sender { levelCount = levelCount - 1; self.levelNumber.text = [NSString stringWithFormat:@"%i", levelCount]; } - (IBAction)gearUpButton:(id)sender { gearCount = gearCount + 1; self.gearNumber.text = [NSString stringWithFormat:@"%i", gearCount]; } - (IBAction)gearDownButton:(id)sender { gearCount = gearCount - 1; self.gearNumber.text = [NSString stringWithFormat:@"%i", gearCount]; } - (IBAction)oneShotUpButton:(id)sender { oneShotCount = oneShotCount + 1; self.oneShotNumber.text = [NSString stringWithFormat:@"%i", oneShotCount]; } - (IBAction)oneShotDownButton:(id)sender { oneShotCount = oneShotCount - 1; self.oneShotNumber.text = [NSString stringWithFormat:@"%i", oneShotCount]; } @end </code></pre>

    1. COSide note - why did you declare global variables for `levelCount`, `gearCount`, etc. in the .h file? Why aren't these private ivars instead of globals?

    2. COHonestly, because I have no idea what I'm doing. I don't expect you to teach me everything but if you're willing I wouldn't mind knowing the difference. I've been trying to learn objective C but books and whatnot are outdated.

    3. COStart with a good book or tutorial on the Objective-C programming language. The book by Stephen G. Kochan is very good. Writing apps requires knowledge of the language first.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
