Sample App - BlankProject.zip

**Overview:**

Appears that when using a ListView with multiple Entry fields, the Listview scrolling and reuse can jumble up the Keyboard types.

Screencast - *See Private Comment Below*
Sample App - *Attached Above* BlankApp.zip
Code Snip - https://gist.github.com/mattregul/c84ce11ee9996aa514b9#file-keyboard-xaml


**Steps to Reproduce:**

Run the Sample App - *Attached Above* BlankApp.zip
Scroll down to Keyboard in the MasterDetail menu
Scroll up and down on the page a few times
After Reuse occurs, some of the entry fields will produce the wrong keyboard type


**Actual Results:**

At times the wrong keyboard type is displayed for the entry field
ex: Email for a normal Text field.


**Expected Results:**

Correct keyboard type every time

There's a workaround. Put the follwing in a custom renderer's OnElementChanged

            var viewKeyboard = e.NewElement.Keyboard;
            Control.AutocorrectionType = viewKeyboard == Keyboard.Text ? UITextAutocorrectionType.Default : UITextAutocorrectionType.No;

            if (viewKeyboard == Keyboard.Email)
            {
                Control.KeyboardType = UIKeyboardType.EmailAddress;
            }
            else if (viewKeyboard == Keyboard.Numeric)
            {
                Control.KeyboardType = UIKeyboardType.NumberPad;
            }
            else if (viewKeyboard == Keyboard.Telephone)
            {
                Control.KeyboardType = UIKeyboardType.PhonePad;
            }
            else if (viewKeyboard == Keyboard.Url)
            {
                Control.KeyboardType = UIKeyboardType.Url;
            }
            else
            {
                Control.KeyboardType = UIKeyboardType.Default;
            }

Hi Christian, thank you for your attention.

Your workaround works perfectly.

I'm not able to reproduce this on iOS using 2.4.0.269-pre2
