Cocoa - How do I initialize a view programmatically ?

Question

I have a problem understanding how to initialize a view without hooking it up in my nib-file. So what I want to do is, instead of dragging in a view and assigning it a dedicated class, I want to programmatically add it to my window in my app delegate.

I don't really know how wrong this is, but I tried something like this in my AppDelegate:

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
    DView *dV = [[DView alloc]initWithFrame:NSMakeRect(0, 0, 1000, 600)];
    [self.window addSubview:dV];
}

I figured that the window is an NSView as well, so why not just add it to it ? But this crashes and ends in an infinite loop. I hope you can help me. Thanks.

Answer 1

yes,

MONView * view = [[MONView alloc] initWithFrame:someFrame];

is correct.

It is not an NSView (it is an NSResponder). As Richard Stahl points out, you should interact with the window's content view instead: [window.contentView addSubview:view];
