UIModalViewController Hidden behind a UIViewController - objective-c

Question

I am working with a sliding menu, like you would see in the Facebook or Path app.
In the rear menu I am wanting to allow the user to add an image by using the camera or photo library.
The issue I am having is the main view controller, the one that I slide, is always on top.
The Action Sheet presents just fine, but the modal view controller is hidden partially by the main view controller.
Here's my picker code:
- (void)viewDidLoad
{
[super viewDidLoad];
_UIPicker = [[UIImagePickerController alloc] init];
_UIPicker.delegate = self;
}
- (IBAction)profilePicButtonTapped
{
UIActionSheet * actionSheet = [[UIActionSheet alloc] initWithTitle:#"Set Up Your Profile Picture" delegate:self cancelButtonTitle:#"Cancel" destructiveButtonTitle:nil otherButtonTitles:#"Camera", #"Photo Library", nil];
actionSheet.actionSheetStyle = UIActionSheetStyleBlackOpaque;
[actionSheet showInView:_rearTableView];
}
-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
if (buttonIndex == 0)
{
_UIPicker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentViewController:_UIPicker animated:YES completion:nil];
}
else if (buttonIndex == 1)
{
_UIPicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentViewController:_UIPicker animated:YES completion:nil];
}
else
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:nil message:#"Error" delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:nil];
[alert show];
}
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
UIImage * selectedImage = [info objectForKey:UIImagePickerControllerOriginalImage];
_profileImageView.image = selectedImage;
[self dismissViewControllerAnimated:YES completion:nil];
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
{
[picker dismissViewControllerAnimated:YES completion:nil];
}

A quick way to solve it would be to hide the main ViewController when you present the picker and show it again once it's dismissed. Assuming you have a reference to the main ViewController, just set it's view.hidden property to YES.
Another way to handle it would be to present it from the main ViewController instead of the rear menu.
