旋转控制没有效果

[ChengminZhang]

Bug 表现

安装 QMUI 4.0.0-beta 后旋转出了问题。

QMUI-3.2.1版本我设置了BaseViewController->UIInterfaceOrientationMaskPortrait，某些页面支持UIInterfaceOrientationMaskAll，在3.2.1表现很好，4.0.0-beta版本后出现没有作用的情况。

猜测原因

4.0.0 版本 QMUITabBarViewController 通过supportedInterfaceOrientations设置可用的旋转方向，shouldAutorotate控制当前旋转方向。
3.2.1 版本 QMUITabBarViewController 通过supportedInterfaceOrientations控制旋转方向。

将 QMUITabBarViewController下的 supportedInterfaceOrientations 替换回 3.2.1版本的 supportedInterfaceOrientations写法不会出现该问题。

//QMUI 4.0.0-beta.
#pragma mark - 屏幕旋转

- (BOOL)shouldAutorotate {
    return self.presentedViewController ? [self.presentedViewController shouldAutorotate] : ([self.selectedViewController qmui_hasOverrideUIKitMethod:_cmd] ? [self.selectedViewController shouldAutorotate] : YES);
}

- (UIInterfaceOrientationMask)supportedInterfaceOrientations {
    
    // fix UIAlertController:supportedInterfaceOrientations was invoked recursively!
    // crash in iOS 9 and show log in iOS 10 and later
    // https://github.com/Tencent/QMUI_iOS/issues/502
    // https://github.com/Tencent/QMUI_iOS/issues/632
    UIViewController *visibleViewController = self.presentedViewController;
    if (visibleViewController && [visibleViewController isKindOfClass:UIAlertController.class]) {
        visibleViewController = self.selectedViewController;
    }
    
    return [visibleViewController qmui_hasOverrideUIKitMethod:_cmd] ? [visibleViewController supportedInterfaceOrientations] : SupportedOrientationMask;
}

//QMUI 3.2.1
#pragma mark - 横竖屏
- (UIInterfaceOrientationMask)supportedInterfaceOrientations {
    // QMUI 4.0.0 -beta 修改这段代码，回退代码可以避免问题。
    UIViewController *presentedViewController = self.presentedViewController;
    if (IOS_VERSION_NUMBER < 100000 && presentedViewController && [presentedViewController isKindOfClass:UIAlertController.class]) {
        presentedViewController = nil;
    }
    
    return presentedViewController ? [presentedViewController supportedInterfaceOrientations] : ([self.selectedViewController qmui_hasOverrideUIKitMethod:_cmd] ? [self.selectedViewController supportedInterfaceOrientations] : SupportedOrientationMask);
}

这是 4.0.0-beta 的 bug，新版本将会修复，在此之前可以按照下文替换正确的代码：

QMUITabBarViewController.m:

- (BOOL)shouldAutorotate {
    return self.presentedViewController ? [self.presentedViewController shouldAutorotate] : ([self.selectedViewController qmui_hasOverrideUIKitMethod:_cmd] ? [self.selectedViewController shouldAutorotate] : YES);
}

- (UIInterfaceOrientationMask)supportedInterfaceOrientations {
    
    // fix UIAlertController:supportedInterfaceOrientations was invoked recursively!
    // crash in iOS 9 and show log in iOS 10 and later
    // https://github.com/Tencent/QMUI_iOS/issues/502
    // https://github.com/Tencent/QMUI_iOS/issues/632
    UIViewController *visibleViewController = self.presentedViewController;
    if (!visibleViewController || visibleViewController.isBeingDismissed || [visibleViewController isKindOfClass:UIAlertController.class]) {
        visibleViewController = self.selectedViewController;
    }
    
    if ([visibleViewController isKindOfClass:NSClassFromString(@"AVFullScreenViewController")]) {
        return visibleViewController.supportedInterfaceOrientations;
    }
    
    return [visibleViewController qmui_hasOverrideUIKitMethod:_cmd] ? [visibleViewController supportedInterfaceOrientations] : SupportedOrientationMask;
}

QMUINavigationController.m:

- (BOOL)shouldAutorotate {
    return [self.visibleViewController qmui_hasOverrideUIKitMethod:_cmd] ? [self.visibleViewController shouldAutorotate] : YES;
}

- (UIInterfaceOrientationMask)supportedInterfaceOrientations {
    // fix UIAlertController:supportedInterfaceOrientations was invoked recursively!
    // crash in iOS 9 and show log in iOS 10 and later
    // https://github.com/Tencent/QMUI_iOS/issues/502
    // https://github.com/Tencent/QMUI_iOS/issues/632
    UIViewController *visibleViewController = self.visibleViewController;
    if (!visibleViewController || visibleViewController.isBeingDismissed || [visibleViewController isKindOfClass:UIAlertController.class]) {
        visibleViewController = self.topViewController;
    }
    return [visibleViewController qmui_hasOverrideUIKitMethod:_cmd] ? [visibleViewController supportedInterfaceOrientations] : SupportedOrientationMask;
}
