I'm wondering how I should deal with overriding "designated
initailizers". I really have no clue about the part "self =
[super...]. KeyboardView is a subclass of NSView.
@implementation KeyboardView
- (id)initWithFrame:(NSRect)frame {
self = [super initWithFrame:frame];
if (self) {
// Initialization code here.
}
return self;
}
@end
This is what I came up with so far:
override KeyboardView initWithFrame(NSRect frame)
[initWithFrame:] {
//my stuff
return cast(KeyboardView) super.initWithFrame(frame) ;
}
This compiles and does not throw any runtime error, but it's a
bit against the idea, because in Objective-C the idea is to first
call the super class, then adapt and override what is necessary.
When calling super in the very end, this of course is no longer
guaranteed.
