how could I get the frame of a rightbarbuttonItem in swift? I found this : UIBarButtonItem: How can I find its frame? but it says cannot convert NSString to UIView, or cannot convert NSString to String :
let str : NSString = "view" //or type String
let theView : UIView = self.navigationItem.rightBarButtonItem!.valueForKey("view")//or 'str'
The goal is to remove the rightBarButtonItem, add an imageView instead, and move it with a fadeOut effect.
Thanks
You should try it like:
var barButtonItem = self.navigationItem.rightBarButtonItem!
var buttonItemView = barButtonItem.valueForKey("view")
var buttonItemSize = buttonItemView?.size
Edit (Swift 3):
var barButtonItem = self.navigationItem.rightBarButtonItem!
let buttonItemView = barButtonItem.value(forKey: "view") as? UIView
var buttonItemSize = buttonItemView?.size
