UIImagePickerController的拍照按钮不起作用

Question

我将此代码放入两个项目中。在一个项目中，我只需按下拍照按钮即可拍照。在另一个项目中，我必须长按按钮才能拍照。请帮帮我。

UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;

picker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentViewController:picker animated:YES completion:NULL];

Answer 1

这对我来说非常有用..

   var imagePicker: UIImagePickerController! = UIImagePickerController()

    @IBAction func takepic(sender: AnyObject) {
    imagePicker =  UIImagePickerController()
    imagePicker.delegate = self
    imagePicker.sourceType = .Camera
    imagePicker.cameraCaptureMode = .Photo
    imagePicker.cameraDevice = .Front;


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