+## ios 16 旋转
+
+若想在 iOS 16 上强制旋转生效
+1. 保证 info.plist 表里 Supported interface orientations 不要四个方向都勾上
+2. 请在 AppDelegate 中加入如下代码，允许所有旋转方向
+    
+```js
+- (UIInterfaceOrientationMask)application:(UIApplication *)application
+    supportedInterfaceOrientationsForWindow:(UIWindow *)window {
+     return UIInterfaceOrientationMaskAll;
