Expected Results

What did you expect to happen?
Setting rightAccessoryButton will remove the cancel button.

Actual Results

Setting rightAccessoryButton did not remove the cancel button.

Investigation

Currently the initialization flow is:

-initWithStyle:passcodeType
|_ -setUp
   |_ -view
      |_ -loadView
      |_ -viewDidLoad
         |_  -setUpAccessoryButtons

The problem begins with line 82: self.view.backgroundColor = [UIColor clearColor];. self.view triggers -loadView and in turn -viewDidLoad where the heavy view set up takes place. Then when -setUpAccessoryButton is called at line 175, the if statement is always true because it's called before the user has a chance to set rightAccessoryButton. Setting it after initialization has no effect because the logic is under -viewDidLoad.

In general calling self.view in -init should be avoided.
