我想自定义相机场景，所以我使用自定义叠加。它隐藏了默认的相机按钮并显示其他按钮。当我拍照时，我想看到静态图像，但我只看到了相机。我尝试在customView中放置一个图像视图，但相机仍然在后台运行。
func cameraProperty()
{
DispatchQueue.main.async(execute: {
//let imagePicker = UIImagePickerController()
self.picker.navigationBar.isTranslucent = false
self.picker.navigationBar.barTintColor = .blue // Background color
self.picker.navigationBar.tintColor = .white // Cancel button ~ any UITabBarButton items
self.picker.navigationBar.titleTextAttributes = [
NSForegroundColorAttributeName : UIColor.white
] //
self.picker.sourceType = UIImagePickerControllerSourceType.camera
self.picker.cameraDevice = .front
self.picker.delegate = self
self.picker.showsCameraControls = false
self.picker.modalPresentationStyle = .fullScreen
//customView stuff
let customViewController = CustomOverlayViewController(
nibName:"CustomOverlayViewController",
bundle: nil
)
let customView:CustomOverlayView = customViewController.view as! CustomOverlayView
customView.frame = self.picker.view.frame
customView.delegate = self
customView.skipBtn.setTitle("SKIP", for: .normal)
customView.createSongBtn.isHidden = true
customView.takePhotoBtn.isHidden = false
customView.curImg.isHidden = true
//CGSize screenSize = [[UIScreen mainScreen] bounds].size;
let screenSize:CGSize = UIScreen.main.bounds.size
let ratio:CGFloat = 4.0 / 3.0
let cameraHeight:CGFloat = screenSize.width * ratio
let scale:CGFloat = screenSize.height / cameraHeight
//need to test it for different phone sizes
self.picker.cameraViewTransform = CGAffineTransform(translationX: 0, y: (screenSize.height - cameraHeight) / 2.0)
self.picker.cameraViewTransform = self.picker.cameraViewTransform.scaledBy(x: scale, y: scale)
self.picker.cameraOverlayView = customView
self.picker.allowsEditing = false
})
}
func imagePickerControllerDidCancel(_ picker: UIImagePickerController){
picker.dismiss(animated: true, completion: nil)
}
//MARK: Custom View Delegates
func didCancel(overlayView:CustomOverlayView) {
DispatchQueue.main.async(execute: {
if overlayView.skipBtn.titleLabel?.text == "SKIP"
{
self.picker.dismiss(animated: true,completion: nil)
print("dismissed!!")
}
else
{
overlayView.skipBtn.setTitle("SKIP", for: .normal)
overlayView.createSongBtn.isHidden = true
// overlayView.curImg.isHidden = true
overlayView.takePhotoBtn.isHidden = false
print("Reset camera")
}
})
}
func didShoot(overlayView:CustomOverlayView) {
DispatchQueue.main.async(execute: {
self.picker.takePicture()
overlayView.skipBtn.setTitle("Try Again", for: .normal)
// overlayView.sendSubview(toBack: overlayView.curImg)
overlayView.createSongBtn.isHidden = false
overlayView.takePhotoBtn.isHidden = true
})
print("Shot Photo")
}
如何使用图像（也是自定义视图）和“使用照片”选项显示视图。
