标签: swift uiimagepickercontroller snapshot ios8.2

我在这个网站上看过很多帖子(特别是这个:iOS 8 Snapshotting a view that has not been rendered results in an empty snapshot)但是Swift没有答案。

以为如果他们已经解决了这个问题,我会问这里的人群。

我在iPhone 6上使用Xcode 6.2,iOS 8.2

我的代码:

if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.Camera){
        if(UIImagePickerController .isSourceTypeAvailable(UIImagePickerControllerSourceType.Camera)){
            imag = UIImagePickerController()
            imag.delegate = self
            imag.sourceType = UIImagePickerControllerSourceType.Camera;
            imag.allowsEditing = false
            imag.mediaTypes = [kUTTypeImage]
            imag.showsCameraControls = false
            self.presentViewController(imag, animated: true, completion: nil)
            imag.cameraDevice = UIImagePickerControllerCameraDevice.Front
            imag.takePicture()
        }
    }

如果我将此(self.presentViewController(imag,animated:true,completion:nil))改为(self.presentViewController(imag,animated:YES,completion:nil)),我得到并错误切换回true

答案 0 :(得分:0)

我在控制台中收到相同的警告,但其他一切都应该有效。如果相机未显示,请在设备设置中检查相机权限。
