let view = UIView(frame: CGRect(x: 0, y: 0, width: 320, height: 568))
addSubview(view)
view.autoresizingMask = UIViewAutoresizing.FlexibleWidth | UIViewAutoresizing.FlexibleHeight
会报以下错误：
Binary operator '|' cannot be applied to two UIViewAutoresizing operands
更改为：
view.autoresizingMask = [.FlexibleWidth, .FlexibleHeight]
即可解决
但是在极光推送中遇到同样问题后，这样并不行
原OC代码：
      [JPUSHService registerForRemoteNotificationTypes:(UIUserNotificationTypeBadge |
                                                        UIUserNotificationTypeSound |
                                                        UIUserNotificationTypeAlert)
                                            categories:nil];
转为swift
        JPUSHService.registerForRemoteNotificationTypes(UIUserNotificationType.Badge.rawValue | UIUserNotificationType.Sound.rawValue | UIUserNotificationType.Alert.rawValue, categories: nil)
就是swift 和 OC 在枚举上的区别导致的
