Team,

I am trying to bring a menu in top of all visible views during runtime. This menu should be easily addable and removable dynamically in certain conditions.

To do this, I have tried adding a button view to the UIWindow as a subview during runtime.

UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button addTarget:self action:nil forControlEvents:UIControlEventTouchDown];
[button setTitle:@"Show View" forState:UIControlStateNormal];
button.frame = CGRectMake(80.0, 210.0, 160.0, 40.0);
[window addSubview:button];
[window makeKeyAndVisible];
[window bringSubviewToFront:button];

But it doesnt worked. Also I have tried to place this button in the root view controller, but no luck again.

Edit - Note: This code is not from a UIViewController. I am trying to build a library this will be in that library code. Use case be like you could post NSNotification to enable and disable this menu dynamically during runtime.

Please suggest.

Thanks !
