I'm looking for a simple method to remove at once all subviews from a superview instead of removing them one by one.
//I'm trying something like this, but is not working
let theSubviews : Array = container_view.subviews
for (view : NSView) in theSubviews {
view.removeFromSuperview(container_view)
}
What I am missing?
UPDATE
My app has a main container_view
. I have to add different other views as subviews to container_view
in order to provide a sort of navigation.
So, when clicking the button to "open" a particular page, I need to remove allsubviews and add the new one.
UPDATE 2 - A working solution (OS X)
I guess Apple fixed it.
Now it is more easy than ever, just call:
for view in containerView.subviews{
view.removeFromSuperview()
}
EDIT: (thanks Jeremiah / Rollo)
By far the best way to do this in Swift for iOS is:
view.subviews.forEach({ $0.removeFromSuperview() }) // this gets things done
view.subviews.map({ $0.removeFromSuperview() }) // this returns modified array
^^ These features are fun!
let funTimes = ["Awesome","Crazy","WTF"]
extension String {
func readIt() {
print(self)
}
}
funTimes.forEach({ $0.readIt() })
//// END EDIT
Just do this:
for view in self.view.subviews {
view.removeFromSuperview()
}
Or if you are looking for a specific class
for view:CustomViewClass! in self.view.subviews {
if view.isKindOfClass(CustomViewClass) {
view.doClassThing()
}
}
