ios 카메라 app swift 3

Question

캡쳐 및 이미지 저장 기능을 사용하여 앱에서 카메라 인터페이스를 원하지만이 앱을 실행할 때 아무 것도 얻을 수 없으며 빌드가 오류없이 성공적이지만 아무 것도 viewController에 표시되지 않습니다. .

Answer 1

class ViewController: UIViewController , UINavigationControllerDelegate, UIImagePickerControllerDelegate{ 

@IBOutlet var imageView: UIImageView! 


@IBOutlet var TakePhoto: UIButton! 
var imagePick: UIImagePickerController! 
var newMedia: Bool? 

@IBAction func TakePhoto(_ sender: AnyObject){ 

    if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.camera){ 
     let imagePick = UIImagePickerController() 
     imagePick.delegate = self 
     imagePick.sourceType = UIImagePickerControllerSourceType.camera 
     imagePick.mediaTypes = [kUTTypeImage as String] 
     imagePick.allowsEditing = false 

     self.present(imagePick, animated: true, completion: nil) 

     newMedia = true 

    } 

} 

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) { 
    let mediaType = info[UIImagePickerControllerMediaType] as! NSString 
    if mediaType.isEqual(to: kUTTypeImage as String){ 
     let image = info[UIImagePickerControllerOriginalImage] as! UIImage 
     imageView.image = image 

     if(newMedia == true){ 
      UIImageWriteToSavedPhotosAlbum(image, self, #selector(ViewController.image(image:didFinishSavingWithError:contextInfo:)), nil) 
     } //else if mediaType.isEqual(to: kUTTypeMovie as String) 

     self.dismiss(animated: true, completion: nil) 

    } 
} 

func image(image: UIImage, didFinishSavingWithError error: NSErrorPointer, contextInfo:UnsafeRawPointer){ 
    if error != nil{ 
     let alert = UIAlertController(title: "Save Failed", message: "Failed to save the image", preferredStyle: UIAlertControllerStyle.alert) 

     let cancelAction = UIAlertAction(title: "OK", style: .cancel, handler: nil) 

     alert.addAction(cancelAction) 
     self.present(alert, animated: true, completion: nil) 
    } 
} 

}는 당신의 Info.plist에서 카메라를 사용할 수있는 권한을 설정 했습니까? 왜
