在AppDelegate實現方法以下:app
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window { if ([window.rootViewController isKindOfClass:NSClassFromString(@"TabBarController")]) { UITabBarController * tabVC = (UITabBarController *)window.rootViewController; if (tabVC.selectedIndex == 0 || tabVC.selectedIndex == 1) { return UIInterfaceOrientationMaskAll;//這裏須要支持旋轉 } } return UIInterfaceOrientationMaskPortrait; }
