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?

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) ];
}
