Try this:

- (void) someMethodToSaveView: (NSView *) view toTIFF: (NSString *) path
{
        NSBitmapImageRep        * rep = [NSBitmapImageRep alloc];
        NSImage                 * image = [NSImage alloc];
        NSFileHandle            * file;

        [view lockFocus];
        [rep initWithFocusedViewRect: [view frame]];
        [view unlockFocus];
        [image initWithSize: [view frame].size];
        [image addRepresentation: rep];
        RELEASE (rep);
        file = [NSFileHandle fileHandleForWritingAtPath: path];
        [file writeData: [image TIFFRepresentation]];
        RELEASE (image);
};
