ios - 如何删除 UIImagePickerController 中的缩放 slider

Question

我需要移除相机屏幕中的缩放 slider 。这是我的代码:

import UIKit

extension UIImagePickerController {
    class func sourceCameraModePhoto(_ delegate: UIImagePickerControllerDelegate & UINavigationControllerDelegate, overlayView: UIView) -> UIImagePickerController {
        let picker = UIImagePickerController()
        picker.sourceType = .camera
        picker.cameraCaptureMode = .photo
        picker.showsCameraControls = false
        picker.view.addSubview(overlayView)
        picker.delegate = delegate
        return picker
    }

Answer 1

我想找到了这个问题的答案:缩放 slider 是一个 UISlider，如果您的 imagePickerController 的 View 属性在其 subview 下包含一个 UISlider，您可以将其 alpha 设置为零。如果您升级到 iOS10，就会出现此问题。

func subviews(_ view: UIView) -> [UIView] {
    return view.subviews + view.subviews.flatMap { subviews($0) }
}

let myViews = subviews(imagePickerController.view)
for view in myViews {
    if view is UISlider {
        view.alpha = 0.0
    }
}

希望对您有所帮助。
