You should first override your |drawRect:| method of your NSView subclass.

Then you can use the following method:

- (void)drawTiledInRect:(NSRect)rect origin:(NSPoint)inOrigin
operation:(NSCompositingOperation)inOperation
{
 NSGraphicsContext* gc = [NSGraphicsContext currentContext];
 [gc saveGraphicsState];

 [gc setPatternPhase:inOrigin];

 NSColor* patternColor = [NSColor colorWithPatternImage:self];
 [patternColor set];
 NSRectFillUsingOperation(rect, inOperation);

 [gc restoreGraphicsState];
}

... To draw the background like this:
NSPoint patternOrigin = [self convertPoint:NSMakePoint(0.0f, 0.0f) toView:nil];
[yourNSImageItem drawTiledInRect:aRect origin:patternOrigin
operation:NSCompositeCopy];

Hello all!

I am trying to make my custom view have a background image. What I
did is:

1. Add the UIbackground.png image to the project and the interface
builder (shows as UIbackground in the "Images" tab of the builder)

2. Select all GUI elements, Layout -> make subview of -> custom view,
set the custom class of this custom view to NSImageView

3. Define a connection

@interface SinevibesTransformerView : NSView
{
        IBOutlet NSImageView *                          uiView;
...
}

4. In the interface builder, connect the NSImageView custom view to
uiView

5. Then in @implementation of my view:

- (void)awakeFromNib
{
        [uiView setImage: [NSImage imageNamed: @"UIbackground"]];
}

Is this the correct way? Asking this because it compiles fine but
doesn't work ;-)

Thanks for any hints,

Artemiy.
