请清楚地描述您的问题。
-
sorry..if (index == NSNotFound){ return nil // 类型 'UIViewController' 不符合协议 'NilLiteralConvertible' } index++ if (index == self.pageTitles.count){ return nil // 类型 'UIViewController' 不符合协议 'NilLiteralConvertible' }
-
class ViewController: UIViewController, UIPageViewControllerDataSource{ ///Type 'ViewController' 不符合协议 'UIPageViewControllerDataSource'
-
self.pageViewController.ViewControllers(viewControllers, direction: .Forward, animated: true, completion: nil) //找不到成员'Forward'
