Question

我正在使用Fusuma https://github.com/ytakzk/Fusuma并且在Fusuma中可以使用代码进行微小修改，因此在选择照片或拍摄之后它会将我带到新的视图控制器，例如uploadViewcontroller，其中选择的图像呈现（稍后它会在拍照确认或重拍后再做另一种观点是好的吗？

Answer 1

只需在image selection delegate

中编写导航代码即可

如果您支持allowMultipleSelection = true

然后在那里写导航代码

func fusumaMultipleImageSelected(_ images: [UIImage], source: FusumaMode) {

            print("Number of selection images: \(images.count)")

            // your navigation code
            let viewController = UIViewController()
            self.present(viewController, animated: true, completion: nil)

}

如果您支持一个选择allowMultipleSelection = false

在那里写下导航代码

func fusumaImageSelected(_ image: UIImage, source: FusumaMode) {

        switch source {

        case .camera:

            print("Image captured from Camera")

        case .library:

            print("Image selected from Camera Roll")

        default:

            print("Image selected")
        }

        // set you controller there

        let viewController = UIViewController()
        self.present(viewController, animated: true, completion: nil)
      //   imageView.image = image
    }

是的，您可以实施FusumaDelegate方法fusumaImageSelected（或fusumaMultipleImageSelected，在那里写任何导航代码（例如segues，navigationController＆quot; pushViewController方法或viewControllers＆＃39;现在）并通过它传递您的图像。

import UIKit
import Fusuma

class ViewController: UIViewController {
    @IBOutlet weak var photoLibraryButton: UIButton!

    let fusuma = FusumaViewController()

    override func viewDidLoad() {
        super.viewDidLoad()

        fusuma.delegate = self
        fusuma.allowMultipleSelection = true

    }

    @IBAction
    func showPhotoLibrary() {
        self.present(fusuma, animated: true, completion: nil)
    }

}

extension ViewController: FusumaDelegate {
    func fusumaImageSelected(_ image: UIImage, source: FusumaMode) {

        let vc = UploadViewController()
        vc.image = image

        self.navigationController?.pushViewController(vc, animated: true)

    }

    func fusumaMultipleImageSelected(_ images: [UIImage], source: FusumaMode) {
        let vc = UploadViewController()
        guard let firstImage = images.first else { return }
        vc.image = firstImage

        self.navigationController?.pushViewController(vc, animated: true)
    }

    func fusumaVideoCompleted(withFileURL fileURL: URL) {

    }

    func fusumaCameraRollUnauthorized() {

    }

}

然后在UploadViewController中你可以做任何你想做的事情：

import UIKit

class UploadViewController: ViewController {

    public var image = UIImage()
    var imageView: UIImageView!

    override func viewDidLoad() {
        super.viewDidLoad()

        imageView = UIImageView(frame: view.frame)
        imageView.image = self.image

        view.addSubview(imageView)

    }
}

选择图像或拍照并转到新的ViewController
