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.
