如何将UIImagePickerControllerSourceTypeCamera打开成一个小的弹出子视图

Question

我正在尝试将UIImagePickerControllerSourceTypeCamera打开到一个小弹出子视图中，但是每次尝试这个时它都会转到全屏摄像头......这是我第一次尝试使用我读过的相机开发者网站上的所有文档，我都找不到任何解释如何做我想做的事情。

下面是我的startCamera方法，其中我创建一个子视图，然后创建cameraView将cameraView添加到小子视图然后我将它加载到主UIView ....但如上所述它每次都全屏显示:(

任何帮助使这个cameraView看起来像一个小的弹出视图将不胜感激。

#pragma StartCamera
- (IBAction)startCamera:(id)sender {

    if (isCameraViewLoaded == NO) {
        // Load View for camera
        cameraView = [[UIView alloc] initWithFrame:CGRectMake(100.0, 100.0, 200.0, 100.0)];
        cameraView.backgroundColor = [UIColor greenColor];


        // imagepicker stuff
        // check for rear facing camera to continue
        if( [UIImagePickerController isCameraDeviceAvailable:UIImagePickerControllerCameraDeviceRear])
        {
            // load imagePickController into subview
           UIImagePickerController *imagePickController=[[UIImagePickerController alloc]init];
            imagePickController.sourceType=UIImagePickerControllerSourceTypeCamera;
            imagePickController.delegate=self;
            imagePickController.allowsEditing=TRUE;
            imagePickController.modalPresentationStyle = UIModalPresentationCurrentContext;
            [cameraView addSubview:imagePickController.view];
        }
        else {
            // if there is no camera on the device give warning
            UIAlertView *noCameraAlert = [[UIAlertView alloc] initWithTitle:@"Incompatible Device" message:@"Sorry, This feature requiers a rear facing camera" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];

            [noCameraAlert show];
        }

        // pass camera View to mainview
        [self.view addSubview:cameraView];
        isCameraViewLoaded = YES;
    }else{
        [cameraView removeFromSuperview];
        isCameraViewLoaded = NO;
    }

}
