ios - iOS 7 中的自定义 UIView 方向问题

Question

我在 iPad 应用程序中自定义 UIView 显示(如警告消息)的方式在 iOS 8 及更高版本中工作正常，但 iOS 7 View 仅在纵向模式下显示？

我的 iPad 应用程序部署目标是 iOS 7，设备方向仅为横向左和横向右。

在你的方法中 - (CGRect)getBounds

UIInterfaceOrientationIsPortrait 和 UIInterfaceOrientationIsLandscape 方法仅适用于 ios8 及更高版本

Availability

Available in iOS 8.3 and later.

手动检查这些情况

enum UIInterfaceOrientation : Int {
    case Unknown
    case Portrait
    case PortraitUpsideDown
    case LandscapeLeft
    case LandscapeRight
}
