点击旋转卡死或者旋转出现异常?

按照如下步骤, 配置好旋转即可:

配置旋转

• step 1:

• step 2:

@implementation AppDelegate
- (UIInterfaceOrientationMask)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window {
    return UIInterfaceOrientationMaskAll;
}
@end

/// swift
/// class AppDelegate: UIResponder, UIApplicationDelegate {
///     func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> /// UIInterfaceOrientationMask {
///         return .all
///     }
/// }

• step 3: 创建个 UIViewController 的分类, 将以下内容赋值到 .m 文件中即可.

@implementation UIViewController (RotationControl)
- (BOOL)shouldAutorotate { 
    return NO;
}

- (UIInterfaceOrientationMask)supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskPortrait;
}

@end


@implementation UITabBarController (RotationControl)
- (UIViewController *)sj_topViewController {
    if ( self.selectedIndex == NSNotFound )
        return self.viewControllers.firstObject;
    return self.selectedViewController;
}

- (BOOL)shouldAutorotate {
    return [[self sj_topViewController] shouldAutorotate];
}

- (UIInterfaceOrientationMask)supportedInterfaceOrientations {
    return [[self sj_topViewController] supportedInterfaceOrientations];
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
    return [[self sj_topViewController] preferredInterfaceOrientationForPresentation];
}
@end

@implementation UINavigationController (RotationControl)
- (BOOL)shouldAutorotate {
    return self.topViewController.shouldAutorotate;
}

- (UIInterfaceOrientationMask)supportedInterfaceOrientations {
    return self.topViewController.supportedInterfaceOrientations;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
    return self.topViewController.preferredInterfaceOrientationForPresentation;
}

- (nullable UIViewController *)childViewControllerForStatusBarStyle {
    return self.topViewController;
}

- (nullable UIViewController *)childViewControllerForStatusBarHidden {
    return self.topViewController;
}
@end
