Question

I’m working on creating a rotation of 32 names using UILabels. How would I random rotate all 32 names?

Answer 1

- (IBAction)buttonPressed
{
     int randomInt = rand() % [nameArray count]; 
     [nameLabel setText:[nameArray objectAtIndex:randomInt]]
}

In your .h file you must have:

IBOutlet UILabel *nameLabel;

EDIT

I built this project and here is the exact code I used:
This is the .h file:

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController
{
    IBOutlet UILabel *nameLabel;
    NSArray *nameArray;
}
- (IBAction)buttonPressed;

@end

This is the .m file:

#import "ViewController.h"

@implementation ViewController

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    nameArray = [[NSArray alloc] initWithObjects:@"name1", @"name2", @"name3", @"name4", @"name5", @"name6", nil];
}

- (IBAction)buttonPressed
{
    int randomInt = rand() % [nameArray count]; 
    [nameLabel setText:[nameArray objectAtIndex:randomInt]];
}

- (void)dealloc
{
    [super dealloc];
    [nameArray release];
    nameArray = nil;
}
@end

Make sure that both the UILabel and button actions are connected in interface builder.
