ios - UIImagePickerController 相机预览在 ios9 中变黑

Question

我正在 Xcode 7 中编写以下代码并在其中运行应用程序:

UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = `enter code here`(id)self;
picker.sourceType=UIImagePickerControllerSourceTypeCamera;
[self.navigationController presentViewController:picker animated:YES completion:nil];

但相机预览在 ios9 中变黑，我收到此警告:

My Snapshotting a view that has not been rendered results in an empty snapshot. Ensure your view has been rendered at least once before snapshotting or snapshot after screen updates

Answer 1

试试这个代码片段:

UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.sourceType=UIImagePickerControllerSourceTypeCamera;
picker.modalPresentationStyle = UIModalPresentationCurrentContext;
[self.navigationController presentViewController:picker animated:YES completion:nil];

确保您的设备SETTINGS如下所示:
