Question

I am using NSThread to create new thread that displays images in my application. On the main thread I am working with a table view which is displaying data from XML file, in the same view I am displaying images below. But, displaying images on new thread is not working properly.

- (void)viewDidLoad {
    [super viewDidLoad];
    [NSThread detachNewThreadSelector:@selector(startTheBackgroundJob) toTarget:self withObject:nil];
}

And the method in question:

- (void)startTheBackgroundJob {
    NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];

    currentLocationImageView = [[UIImageView alloc] init];
    NSArray *images = [NSArray arrayWithObjects:img1, img2, nil];
    [currentLocationImageView setAnimationImages:images];
    [currentLocationImageView setAnimationRepeatCount:0];
    [currentLocationImageView setAnimationDuration:5.0];

    [self.view addSubview:currentLocationImageView];
    [pool release];
}

Without even looking at your code, the first thing to tell you is, you MUST perform UI activities on main thread… check this question for details…
