Ios 一个UIImagePickerController，用于单个VC中的多个UIImageView

我使用一个UIImagePickerController在同一个viewController中拾取4个图像

---

我不知道该怎么问这个问题，但如果你看下面的图片，你可能会明白我的意思你可以制作一个

enum

来存储可能的选择器类型（配置文件或ID图片）

---

“不会同时拾取所有图像，我指的是在拾取完第一张图像后，单击另一张图像并拾取另一张图像，然后按第二张图像以拾取另一张图像的正常方式”--这意味着什么？拾取一张图像，然后按第二张图像，我只是说，为了让问题更容易演示，您想展示一个用于拾取个人资料照片的

UIImagePickerController

，然后展示另一个用于拾取身份证照片？（2个单独的选择器）是的，但是如果我必须为每个会令人沮丧的图像编写另一个uiimagePickercontroller，您可以尝试使用Closure扩展几个UIKit类的框架，如果您知道如何检查所有uiimageView（driverPImg，passImg）

nil

我所有的uiimageView都包含拾取的图像您想检查

driverPImg

和

passImg

是否包含图像吗？正如您所说，如果driverPImg！=nil{}和

如果通过！=nil{}

比较'UIImageView'类型的非可选值和'nil'总是返回true

所以我尝试了

如果driverPImg.image！=无（&passImg.image）无（&C）carImg.image！=nil{sendApplyBtn.backgroundColor=UIColor.delevareColor}

即使他只是检查了第一个项目，他也会立即执行代码，因此如果

driverPImg.image！=无

my按钮将在不签入其余条件的情况下更改颜色

enum PictureSelectionType {
    case profilePicture
    case idPicture

    var pictureSelectionType = PictureSelectionType.profilePicture

    /// inside ViewDidLoad... 
    let profileImgTapGestur = UITapGestureRecognizer(target: self, action: #selector(DriverAplication.selectProfileImage))
    driverPImg.addGestureRecognizer(profileImgTapGestur)
        
    let passImgTapGestur = UITapGestureRecognizer(target: self, action: #selector(DriverAplication.selectIDImage))
    passImg.addGestureRecognizer(passImgTapGestur)

   
    @objc func selectProfileImage() {
        /// remember what the picker should return
        pictureSelectionType = .profilePicture

        generator.impactOccurred()
