Question

我尝试将5张图片上传到服务器，并且有5个按钮和5个[RACObserve(self, keyboardType) subscribeNext:^(NSNumber *keyboardType) { NSLog(@"%ld", (long)keyboardType.integerValue); // Or any other user of keyboardType.integerValue, such as: if (keyboardType.integerValue == UIKeyboardTypeURL) { // Do stuff. } }];。如果单击第一个按钮，则应该获取第一个ImageView图像，并且与所有按钮一样，应选择表示ImageView。但是问题是，如果我单击第一个按钮或任何按钮，然后从图库中选择图像，第五个ImageView仅获得图像。

ImageView

Answer 1

 i declared five flags for five button.and i gave tag for each button.


var flag1 = 0
var flag2 = 0
var flag3 = 0
var flag4 = 0
var flag5 = 0

我针对五个按钮给出了五个目标动作

    addAttachBtn1.addTarget(self,action: #selector(selectFirstImage), for: .touchUpInside)
    addAttach2.addTarget(self,action: #selector(selectSecondImage), for: .touchUpInside)
    addAttach3.addTarget(self,action: #selector(selectThirdImage), for: .touchUpInside)
    addAttach4.addTarget(self,action: #selector(selectFourthImage), for: .touchUpInside)
    addAttach5.addTarget(self,action: #selector(selectFifthImage), for: .touchUpInside)


@objc func selectFirstImage(sender: UIButton){
    addAttachBtn1.tag = 1
    flag1 = 1
    alertControllerPOPupView()
    addAttachBtn1.titleLabel?.text = str_Url_name
}

@objc func selectSecondImage(sender: UIButton){
    addAttach2.tag = 2
    flag2 = 2
    alertControllerPOPupView()
    addAttach2.titleLabel?.text = str_Url_name
}
@objc func selectThirdImage(sender: UIButton){
    addAttach3.tag = 1
    flag3 = 1
    alertControllerPOPupView()
    addAttach2.titleLabel?.text = str_Url_name
}
@objc func selectFourthImage(sender: UIButton){
    addAttach4.tag = 1
    flag4 = 1
    alertControllerPOPupView()
}

@objc func selectFifthImage(sender: UIButton){
    flag5 = 1
    addAttach5.tag = 1
    alertControllerPOPupView()
}

之后，我宣布从Gallery进行imagePicking和videoPicking的alertController

 func alertControllerPOPupView(){

    let aletcontroller:UIAlertController = {
        let alert = UIAlertController(title: "Choose Pic From..", message: "please select the picture source", preferredStyle: .actionSheet)
        let camera = UIAlertAction(title: "Camera", style: .default, handler: { (cameraAction) in

            if UIImagePickerController.isSourceTypeAvailable(.camera){

                let cameraPicker =  UIImagePickerController.init()
                cameraPicker.delegate = self
                cameraPicker.sourceType = .camera
                cameraPicker.allowsEditing = false
                self.present(cameraPicker, animated: true, completion: nil)
            }
        })

        let saveAlbum = UIAlertAction(title: "Picture", style: .default, handler: { (galleryAction) in

            if UIImagePickerController.isSourceTypeAvailable(.photoLibrary){
                let cameraPicker =  UIImagePickerController.init()
                cameraPicker.delegate = self
                cameraPicker.sourceType = .photoLibrary
                cameraPicker.allowsEditing = false
                self.present(cameraPicker, animated: true, completion: nil)
            }
        })

        let VideoAlbm = UIAlertAction(title: "Video", style: .default, handler: { (galleryAction) in

            if UIImagePickerController.isSourceTypeAvailable(.photoLibrary){
                let libraryPicker = UIImagePickerController.init()
                libraryPicker.delegate = self
                libraryPicker.sourceType = .photoLibrary
                libraryPicker.mediaTypes = [kUTTypeMovie as String,kUTTypeVideo as String]
                libraryPicker.allowsEditing = false
                    self.present(libraryPicker, animated: true, completion: nil)
            }

        })

        let cancelButton = UIAlertAction(title: "Cancel", style: .cancel, handler: nil)
        alert.addAction(camera)
        alert.addAction(VideoAlbm)
        alert.addAction(saveAlbum)
        alert.addAction(cancelButton)
        return alert
    }()

    self.present(aletcontroller, animated: true, completion: nil)
}

image从厨房拾取并在此处给出路径

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

if flag1 == 1{

    flag1=0
    guard let image1 = info[UIImagePickerController.InfoKey.originalImage]
        as? UIImage else {
            return
    }
    firstImg.image = image1 as UIImage
}

if flag2 == 2{

    flag2=0
    guard let image = info[UIImagePickerController.InfoKey.originalImage]
        as? UIImage else {
            return
    }
    secondImageView.image = image as UIImage
}
if flag3 == 1{
    flag3=0
    guard let image = info[UIImagePickerController.InfoKey.originalImage]
        as? UIImage else {
            return
    }
    thirdImageView.image = image as UIImage
}

if flag4 == 1{
    flag4 = 0
    guard let image = info[UIImagePickerController.InfoKey.originalImage]
        as? UIImage else {
            return
    }
    fourthImageView.image = image as UIImage
}
if flag5 == 1{
    flag5 = 0
    guard let image = info[UIImagePickerController.InfoKey.originalImage]
        as? UIImage else {
            return
    }
    fifthImageView.image = image as UIImage
}
dismiss(animated:true, completion: nil)

}
