I get the below debug output when working with some text fields.
UITextField -webView called. This method is no longer supported with the new text arc
Resetting the simulator solved the issue for me.
In previous iOS versions before iOS 7 all UITextFields and UITextViews had underlying UIWebView to show formatted text. Starting from iOS 7 formatted text is drawn using TextKit framework, so -webView property become deprecated.
It seems Apple frameworks still call the webView
method internally.
