Transparent ViewController to See Parent Below?

Question

I would like to modally add a view controller with a transparent background, so the parent view controller beneath can be seen. (This is in an app for iPhone, not for iPad.)

I have tried this:

TextFieldViewController *vc = [self.storyboard instantiateViewControllerWithIdentifier:@"TextFieldVC"]; vc.modalPresentationStyle = UIModalPresentationCurrentContext; vc.modalTransitionStyle = UIModalTransitionStyleCoverVertical; [self.navigationController presentViewController:vc animated:YES completion:^{}]; 

Without luck and given the view controller a clear color background. My view controller is in a storyboard if that changes anything.

Answer 1

@Josh Kahane set the view controller that will present the transparent view controller with this code at the -ViewDidLoad and be sure to set the alpha channel of the UIViewController View to be lower then 1.

Code:

self.modalPresentationStyle = UIModalPresentationCurrentContext; 

Answer 2

I have been searching for the solution. Now thanks to iOS 8. They has introduced couple of new modalPresentationStyle. one among them is UIModalPresentationOverCurrentContext. Used the same to solve the this issue.

viewcontroller.modalPresentationStyle = UIModalPresentationOverCurrentContext; 

Hope this helps.
