我ELCImagePickerController用来选择多张照片。但是，当我选择照片并单击完成按钮时，它会返回选择相册页面。请帮助我，所以当我选择照片时它应该返回viewController。

这是我使用的代码：

var picker = ELCImagePickerController(imagePicker: ())
 @IBAction func ButtonIsclick(sender: AnyObject) {
    picker.delegate = self

    self.presentViewController(picker, animated: true, completion: nil)
}

func elcImagePickerController(picker: ELCImagePickerController!, didFinishPickingMediaWithInfo info:[AnyObject]!) {
    self.dismissViewControllerAnimated(true, completion: nil)
}

func elcImagePickerControllerDidCancel(picker: ELCImagePickerController!){
    self.dismissViewControllerAnimated(true, completion: nil)
}

编辑：当我调试代码时它从不调用didFinishPickingMediaWithInfo函数

实际上我因为设置错误而面临这个问题delegate。

在我的问题中，我设置delegate为 

picker.delegate = self

这是错误的。正确的方法是设置ELCImagepickerDelegate是

 picker.imagePickerDelegate = self

我解决了它 - 在下面找到完整的最终工作代码 -

问题是我必须将 ELCimagepickerdelegate 添加到类中：

class ViewController: UIViewController, UINavigationControllerDelegate, ELCImagePickerControllerDelegate {

但是我以前每次执行此操作时都会收到错误（类型 viewcontroller 不符合协议），因此解决方案是忽略此错误，直到我在代码中添加下面的 2 个委托方法（停止错误，这非常令人困惑 - 对不起，我是 swift 新手。感谢所有试图帮助的人

整个工作代码：

import UIKit
import ELCImagePickerController

class ViewController: UIViewController, UINavigationControllerDelegate, ELCImagePickerControllerDelegate {

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

var picker = ELCImagePickerController()
    @IBAction func OpenPhotos(_ sender: AnyObject) {

       picker.imagePickerDelegate = self
        self.present(picker, animated: true, completion: nil)

    }



    func elcImagePickerController(_ picker: ELCImagePickerController!, didFinishPickingMediaWithInfo info: [Any]!) {
        dismiss(animated: true, completion: nil)
    }

    func elcImagePickerControllerDidCancel(_ picker: ELCImagePickerController!) {
        dismiss(animated: true, completion: nil)
    }

}
