Question

UITabbarController中有5个项目：VC0，VC1，VC3（默认选中），VC4，VC5。

UITabbarController> NavigationController> VC1> VC1-A

UIImagePickerController在VC1-A中显示：

let imagePickerController = UIImagePickerController()
imagePickerController.sourceType = .photoLibrary
imagePickerController.delegate = self
imagePickerController.allowsEditing = false
self.present(imagePickerController, animated: false)

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
    let info = convertFromUIImagePickerControllerInfoKeyDictionary(info)

    if let image = info[convertFromUIImagePickerControllerInfoKey(UIImagePickerController.InfoKey.originalImage)] as? UIImage{
       topImage.image = image
    }

    picker.dismiss(animated: true, completion: nil)

}

选择图像并关闭选择器后，视图将转到默认的选定项目VC3，而不是VC1-A。

我在App上的一次重新测试中发现了此问题，但我记得之前它可以正常工作。我现在不记得自己做了什么可能会使它不正确，Xcode更新，Swift版本更新？我知道我对此没有任何改变。

以下尝试也不起作用：

self.navigationController?.present(imagePickerController, animated: false)
self.navigationController?.dismiss(animated: true, completion: nil)
self.navigationController?.popViewController(animated: true)
picker.popViewController(animated: true)

现在，我使它像这样工作：

picker.dismiss(animated: true, completion: {
        self.tabBarController?.selectedIndex = 1
    })

但这不是解决问题的好主意，希望有人能给出适当的解决方案。谢谢。

您应该获取VC1-A导航控制器的tabBarController并更改所选索引

picker.dismiss(animated: true) {//dismiss image picker
    if let navigationController = self.navigationController {
        navigationController.popToRootViewController(animated: true)//go to VC1
        navigationController.tabBarController?.selectedIndex = 2//go to VC3
    }
}

UIImagePickerController关闭不正确
