Using an NSString as UIAlertView message:

I can't figure out why this won't work, I've tried it 100 ways. The AlertView shows up with a blank message. Here's my code:

eventChoiceNow = [[UIAlertView alloc] initWithTitle:@"Hurry Up!" message:timeTillRest delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];

timeTillRest is an NSString. and just before calling the alertview an NSLog(@"%@",timeTillRest); displays the string without trouble.

Why would you use an alertview as an instance variable? There's no need for that. It's just as easy as this:

UIAlertView *eventChoiceNow = [[UIAlertView alloc] initWithTitle:@"Hurry Up!" message:timeTillRest delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
[eventChoiceNow show];
[eventChoiceNow release];

This should work just fine. Testing using this code:

NSString *timeTillRest = @"Testing";

    UIAlertView *eventChoiceNow = [[UIAlertView alloc] initWithTitle:@"Hurry Up!" message:timeTillRest delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
    [eventChoiceNow show];

And it works fine. Also testing using:

#import "ViewController.h"

@interface ViewController ()
@property(nonatomic,strong) NSString *timeTillRest;
@end

@implementation ViewController
@synthesize timeTillRest;
- (void)viewDidLoad
{
    [super viewDidLoad];
    timeTillRest = @"Testing";

    UIAlertView *eventChoiceNow = [[UIAlertView alloc] initWithTitle:@"Hurry Up!" message:timeTillRest delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
    [eventChoiceNow show];
    // Do any additional setup after loading the view, typically from a nib.
}

And that works flawlessly too. Make sure you aren't setting that property to nil anywhere.
