Hide/Show all objects in a NSWindow - Cocoa

问题

Quick question. How can I hide and then show all the objects in a NSWindow without doing something terribly tedious and complicated?

回答1:

I may be late to this particular party, but how about this?

[[window contentView] setHidden:YES];

And conversely...

[[window contentView] setHidden:NO];

That's certainly less tedious and complicated. :D

回答2:

for(NSView* view in [[window contentView] subviews])
{
    [view setHidden:YES];
}

回答3:

Assuming everything is a NSView:

//Hide views
for (NSView *view in [[myWindow contentView] subviews]) {
   [view setHidden:YES];
}


//Show views
for (NSView *view in [[myWindow contentView] subviews]) {
   [view setHidden:NO];
}

You will probably need to call a setNeedsDisplay somewhere.

EDITED Sorry, been working in Ruby all day. Edited to make it Objective C :)

Untested, but should get you started.
