Did change in Xcode "Use Auto Layout" to off for my CustomView.
But this did turn off Auto Layout for ALL things in the window. Not quite what
I had in mind. So: back to "On".
Then I added in my CustomView:
- (instancetype)initWithFrame:(NSRect)frameRect
{
self = [ super initWithFrame: frameRect ];
if ( self == nil ) return nil;
self.translatesAutoresizingMaskIntoConstraints = YES;
self.autoresizingMask = NSViewHeightSizable;
return self;
}
But still AutoLayout was messing with my view, setting its size to (0,0).
Finally I settled with:
- (void)windowDidLoad
{
[super windowDidLoad];
[ self performSelector: @selector(updateFrame:) withObject: @(0)
afterDelay: 1 ];
}
This has the (small) disadvantage that the window initially shows a boring grey
custom view for one second.
Kind regards,
Gerriet.
