keyboardWillShow in IOS8 with UIKeyboardWillShowNotification

Question

I am running the same code on an IOS 7 and IOS 8 device with differing results

Given a screen with two text fields

In IOS 7 if I touch the first field keyboa

Answer 1

The reason is the difference in the keyboard. If the second field is a password field this means there is another keyboard under the hood. Therefore the notification is sent twice.
