Question

在我下面的课程中，imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject])没有被调用，我也不明白为什么。这是一个扩展JSQMessagesViewController的类，不知道是否与它有关。

故事板中未添加UIImagePickerController。我猜它是在扩展JSQMessagesViewController时添加的？（不能告诉）

无论如何，我可以看到函数actionSheet确实调出了imagePicker相册，我可以选择一个图像但是imagePicker函数didFinishPickingMediaWithInfo永远不会被调用。

如何将此类指定为其委托？

Here is the complete class code（GitHub上的这个例子正在运行，但我无法让它在我的项目中运行，我缺少什么？）

class ChatViewController: JSQMessagesViewController, UIActionSheetDelegate, UIImagePickerControllerDelegate, UINavigationControllerDelegate {

override func viewDidLoad() {

    super.viewDidLoad()

}

    //DELETED THE REST OF THE CODE OF THIS CLASS TO KEEP THIS QUESTION LENGTH SHORT

func actionSheet(actionSheet: UIActionSheet, clickedButtonAtIndex buttonIndex: Int) {

    NSLog("ChatViewController-> actionSheet(clickedButtonAtIndex)")
    if buttonIndex != actionSheet.cancelButtonIndex {
        if buttonIndex == 1 {
            Camera.shouldStartCamera(self, canEdit: true, frontFacing: true)
        } else if buttonIndex == 2 {
            Camera.shouldStartPhotoLibrary(self, canEdit: true)
        } else if buttonIndex == 3 {
            Camera.shouldStartVideoLibrary(self, canEdit: true)
        }
    }
}

// MARK: - UIImagePickerControllerDelegate



func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) {

    //THIS FUNCTION NEVER GETS CALLED AFTER AN IMAGE IS SELECTED FROM THE PHOTO ALBUM

}



}

Answer 1

Camera.shouldStartPhotoLibrary方法可能会显示UIImagePickerController。检查定义的位置。

imagePickerController didFinishPickingMediaWithInfo未在图像选择
