问题 I've read almost every answer about the new iOS6 autorotation stuff but I still can't manage to do what I want. I have a tabBar. One of the tabs is a NavigationView. When you turn the iPhone to landscape, a modalViewController is loaded. Everything works ok on iOS5 but I can't get the modal view to rotate on iOS6. I've tried subclassing the navigation controller, subclassing the tabbar controller and both!. No way. I'm now very confused. Which one is the responsible of rotating the modalview?

问题 How does one set an accessibility identifier on a custom section header view in a UITableView? For background, since logging the element tree of a table view inside UIAutomation produces a flat list of table cells (UIATableCell instances) intermingled with table group elements (UIATableGroup), being able to identify groups makes it easier to identify the cells that belong to those groups (since they are returned in order). If I set an accessibilityIdentifier explicitly on a custom view that

问题 I have a custom View ( UILabel + UIImage ) which I use as the custom view of my UINavigationController which I set like so: self.navigationItem.titleView = self.myTitleLabel; This works fine in iOS 5 but ceases to work under iOS 6.

Update: As mark pointed out the docs states the following: If this property value is nil , the navigation item’s title is displayed in the center of the navigation bar when the receiver is the top
