Question

I have a custom init method:

- (id) initWithFrame:(CGRect ) frame andImage:(UIImage *) image
{
    self = [super init];
    if (self){
        self.view.frame = frame;
        self.imageView_.image = image;
        self.imageScrollView_.frame = self.view.frame;
        imageOriginalFrame = frame;
        zoomedImageFrame = frame;
         NSLog(@"SCREEN DIM %f AND %f", zoomedImageFrame.size.height, zoomedImageFrame.origin.y);
    }
    return self;
}

and here’s how I present it:

FullSizeImageViewController * fullSize = [[FullSizeImageViewController alloc] initWithFrame:imageOriginalFrame andImage:image];
                    if ([self.delegate respondsToSelector:@selector(fullStoryViewController:presentModalViewController:animated:)]) {
                        [self.delegate fullStoryViewController:self presentModalViewController:fullSize animated:YES];
                    }

However, surprisingly my viewDidLoad is getting called before the initWithFrame. How is this possible?

I am guessing it’s because I call super init? If not how do I do this?

Answer 1

Your viewDidLoad method is not getting called before your initWithFrame:andImage: method. Your viewDidLoad method is getting called during your initWithFrame:andImage: method.

Your initWithFrame:andImage: method contains this line:

self.view.frame = frame;

which is shorthand for this:

[[self view] setFrame:frame];

So your method is calling the -[UIViewController view] method. The -[UIViewController view] method is basically this:

- (UIView *)view {
    if (!_view) {
        [self loadView];
        [self viewDidLoad];
    }
    return _view;
}

Try putting a breakpoint in your viewDidLoad method. When it’s hit, look at the stack trace. You’ll find initWithFrame:andImage: in it.
