Summary:
In an application that makes use of autolayout, set up a UIPickerView with 10 rows. If the method selectRow:inComponent:animated: is called from viewDidLoad or viewWillAppear, the the picker will not successfully select the last row, but will display the next-to-last row.

Steps to Reproduce:
1. Create a project with a UIPickerView contained in a nib that uses autolayout
2. Assign a data source that provides 10 rows.
3. In viewWillAppear, select the last row


Expected Results:
The selected row is displayed

Actual Results:
The view appears with the next to last row selected. All other rows can be selected successfully.

Regression:

Notes:
Calling selectRow: from viewDidAppear selects the row properly, but the UIPickerView either jumps or rotates to the correct row, which doesn't look good
