自定义iphone cameraview（叠加）

Question

我的iPhone应用程序允许用户录制视频。 如何在屏幕截图中自定义我的相机视图。（我还需要自定义timer-countDown）

Answer 1

您需要将所有自定义元素放在UIView中，并将该视图分配给cameraOverlayView属性。

- (void)takePicture {
    if (([UIImagePickerController isSourceTypeAvailable:
          UIImagePickerControllerSourceTypeCamera] == NO)) return;

    UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
    imagePickerController.delegate = self;
    imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
    // add a custom view overlay
    [imagePickerController setCameraOverlayView:customView];

    [self presentModalViewController:imagePickerController animated:YES];
    [imagePickerController release];
}
