NScrollView don't work with opened image

Question

I have scrollview added with interface builder its implemented in NSWindow view and in NSScrollview i added CustomView i'm using this code line in my

AppDelegate.m

- (void)awakeFromNib

id docView = paintingfield;
id viewas = [[NSScrollView alloc] initWithFrame:
                            [[scrollview contentView] frame]];
[scrollview setHasVerticalScroller:YES];
[scrollview setHasHorizontalScroller:YES];
[scrollview setBorderType:NSNoBorder];
[scrollview setAutoresizingMask:NSViewWidthSizable|NSViewHeightSizable];
[scrollview setDocumentView:docView];
[scrollview setContentView:viewas];

an in my AppDelegate.h

IBOutlet NSScrollView * scrollview;
IBOutlet NSView * view;
IBOutlet CustomView *paintingfield;

IBOutlets are linked propertly NSScrollView to NSScrollView, NSView to CustomView, CustomView to CustomView. -awakeFromNib is called the problem is because of NSScrollView when i open image i get blank window instead of opened image with scroll without NSScrollView image opens proper too any ideas how can i fix it?

if i remove this line i get empty window without any View or Opened image — LeTadas, Jul 09 '13 at 08:06
hmm but after i remove this line and Custom view from NSScrollView in interface i get a Opened image with some kind of scroll view i will try to work with that now — LeTadas, Jul 09 '13 at 08:10
and image is not opening correctly because this line sets frame of contentview — LeTadas, Jul 09 '13 at 08:13
you should set up content size like this: [scrollView.documentView setFrame: CGRectMake(0,0,_width, _height) ]; . where _width and _heigt is size of painting field. — stosha, Jul 09 '13 at 08:18
and this line is important because i will use it to center my Custom View — LeTadas, Jul 09 '13 at 08:21

Try change you code like this:

- (void)awakeFromNib
{
    [scrollview setHasVerticalScroller:YES];
    [scrollview setHasHorizontalScroller:YES];
    [scrollview setBorderType:NSNoBorder];
    [scrollview setAutoresizingMask:NSViewWidthSizable|NSViewHeightSizable];
    [scrollview setDocumentView:paintingfield];
    [scrollView.documentView setFrame: CGRectMake(0, 0, paintingfield.frame.size.width,paintingfield.frame.size.height) ];
}
