title: UIToolbar translucent style and certain UIBarButtonSystemItems
body: <p>I wanted to post this "question", which I will answer, to help others who may experience this issue. When using a UIToolbar which is translucent, the UIBarButtonSystemItemPageCurl icon does not appear. Setting barStyle to UIBarStyleBlackTranslucent or setting translucent to TRUE causes this. Adding a UIBarButtonItem with a system item of UIBarButtonSystemItemPageCurl will not appear.</p>
