Display clear colored ViewController over another ViewController in iOS 7 [duplicate]

Answer 1

Why not u r using this

 UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
    UIViewController *vc = [storyboard instantiateViewControllerWithIdentifier:@"SecondViewController"];

    self.modalPresentationStyle = UIModalPresentationCurrentContext;
    [self presentViewController:vc animated:NO completion:nil];

 vc.view.backgroundColor = [UIColor clearColor];

Try to change BG Color of View after view is loaded. in ur sol u r first changing View and the presenting. the View Life cycle not going on this manner

Answer 2

I just followed the original solution and applied some default and custom settings in Interface Builder, and seems to me it is working.

• You can check it here: https://github.com/codedad/SO_IOS_viewcl_on_viewcl

Important section (quite similar to the question's code):

- (IBAction)click:(id)sender {
    NSLog(@"click");


    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
    UIViewController *vc = [storyboard instantiateViewControllerWithIdentifier:@"TopOverVc"];

    vc.view.backgroundColor = [UIColor clearColor];
    self.modalPresentationStyle = UIModalPresentationCurrentContext;
    [self presentViewController:vc animated:NO completion:nil];
}

• Also pls find the IB snaphot:

• And the simulator result (after pressing button):

Hope I did not misunderstand sthing in your question ;) Happy coding!

For iOS 7,subclass SecondViewController and try setting the view background color in viewDidLoad of SecondViewController

self.view.backgroundColor = [UIColor clearColor];
