我想在我的View Controller中简单地放置一个Camera View.

我进口的AVFoundation顶部,以及UIImagePickerControllerDelegate与UINavigationControllerDelegate类.

但是,每当我尝试使用时AVCaptureStillImageOutput,Xcode告诉我它在iOS10中已被弃用,我应该使用AVCapturePhotoOutput.这是完全没问题,但是,只要我想打电话stillImageOutput.outputSettings,.outputSettings它本身就不可用.因此,我必须使用AVAVCaptureStillImageOutput它才能工作,但我有多个警告,因为在iOS10中不推荐使用此功能.

我搜索和搜索,但无法真正找到解决方案.我将衷心感谢您的帮助.我正在学习,所以任何解释都会很棒!代码如下.

import UIKit
import AVFoundation

class CameraView: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {

    var captureSession : AVCaptureSession?
    var stillImageOutput : AVCaptureStillImageOutput?
    var previewLayer : AVCaptureVideoPreviewLayer?

    @IBOutlet var cameraView: UIView!

    override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
        captureSession = AVCaptureSession()
        captureSession?.sessionPreset = AVCaptureSessionPreset1920x1080

        var backCamera = AVCaptureDevice.defaultDevice(withMediaType: AVMediaTypeVideo)
        var error : NSError?

        do {
            var input = try! AVCaptureDeviceInput (device: backCamera)
            if …

所以,我花了两天时间试图弄清楚如何在Swift 3中添加UIButton周围的填充.我设置了一个自定义图像(不是背景图像)并尝试使用以下代码增加可点击区域:

backButton.imageEdgeInsets = UIEdgeInsets(top: -44, left: -44, bottom: -44, right: -44)

但它不起作用!我最大的成功是按钮本身变得更大,可点击区域保持可笑的小.请帮忙.

所以,最近我一直试图在Swift 3中实现从后到前摄像头切换摄像机视图的功能.但是,没有运气.

目前,我的默认视图来自后置摄像头 - 我可以用它拍照然后重新拍摄.但任何人都可以帮助我,并显示如何双击屏幕切换相机或只是使用指定的按钮切换它们？谢谢!
