Question

Hi I have been having problems loading images quickly to the screen. There seems to be a delay the first time I hit the view:

Here is how I load the images:

for (int i = 1; i < 19; i++)
{
    UIImage *image = [UIImage imageNamed:[NSString stringWithFormat:@"%@_Hole%d_", courseName, i]];
    imageView = [[UIImageView alloc] initWithImage:image];
    frame.origin.x = cx;
    imageView.frame = frame;
    [scrollView addSubview:imageView];
    cx += scrollView.frame.size.width;
    imageView = nil;
}

Each image is 640 x 820.

I don’t think there is much else you could do to speed this up.

However, you do have a memory management issue which could speed up the process to some extent.

for (int i = 1; i < 19; i++)     {
     UIImage *image = [UIImage imageNamed:[NSString stringWithFormat:@"%@_Hole%d_", courseName, i]];
     imageView = [[UIImageView alloc] initWithImage:image];
     frame.origin.x = cx;
     imageView.frame = frame;
     [scrollView addSubview:imageView];
     cx += scrollView.frame.size.width;
     [imageView release];
 }
