【问题描述】：

我正在尝试编写一个函数，用户可以使用该函数将图片上传到我的服务器。我想禁止用户从照片卷中选择图片。无论如何我可以使用 ImagePicker pod 做到这一点吗？

func cancelButtonDidPress(imagePicker: ImagePickerController) {
    imagePicker.dismissViewControllerAnimated(true, completion: nil)
}

func wrapperDidPress(imagePicker: ImagePickerController, images: [UIImage]) {
}

func doneButtonDidPress(imagePicker: ImagePickerController, images: [UIImage]) {
    imagePicker.dismissViewControllerAnimated(true, completion: nil)
}

@IBAction func pictureButtonTapped(sender: AnyObject) {
    //take picture
    let imagePickerController = ImagePickerController()
    imagePickerController.imageLimit = 1
    imagePickerController.delegate = self
    presentViewController(imagePickerController, animated: true, completion: nil)
}

【解决方案1】：

您可以将sourceType 设置为camera 以仅作为相机打开图像选择器。

@IBAction func pictureButtonTapped(sender: AnyObject) {
    let imagePickerController = ImagePickerController()
    imagePickerController.imageLimit = 1
    imagePickerController.delegate = self

    // Add these lines

    imagePickerController.sourceType = .camera

    presentViewController(imagePickerController, animated: true, completion: nil)
}

sourceType 确实是我正在寻找的，但我使用的框架（ImagePicker）在上面的代码中给出了编译错误。我决定改用 DKImagePickerController 并且能够让它工作。

【解决方案2】：

import DKImagePickerController


@IBAction func pictureButtonTapped(sender: AnyObject) {
        let pickerController = DKImagePickerController()

        pickerController.didSelectAssets = { (assets: [DKAsset]) in
            let size = CGSizeMake(512, 512)
            assets[0].fetchImageWithSize(size, completeBlock: { image, info in
                self.image = image
                self.pictureButton.setBackgroundImage(self.image, forState: .Normal)
            })
        }

        pickerController.singleSelect = true
        pickerController.maxSelectableCount = 1
        pickerController.sourceType = .Camera

        self.presentViewController(pickerController, animated: true) {}
    }
