You can change the text by using following code. Try to implement in .m File

@interface AudioPlayerDemoViewController ()
{
UIActionSheet *action;
NSString *titleString;
}
@end

@implementation AudioPlayerDemoViewController

- (void)viewDidLoad
{
    [super viewDidLoad];
    titleString = @"Start";
    // Do any additional setup after loading the view, typically from a nib.
}
- (IBAction)actionSheetTap:(id)sender
{
    action = [[UIActionSheet alloc]initWithTitle:@"Demo" delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles:titleString,@"Stop", nil];
    [action showFromBarButtonItem:sender animated:YES];

}

-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
    NSString *title = [actionSheet buttonTitleAtIndex:buttonIndex];

    if([title isEqual: @"Start"])
    {
        action = nil;
        titleString = @"Pause";

    }
    if([title isEqual: @"Pause"])
    {
        action = nil;
        titleString = @"Start";

    }

}
