Show without view controller? about toast

[scalessec]

Hey Tyler, I think you're confusing controllers and views. Toast can care less about controllers, all it needs is a view to be presented in.

If self is a UIViewController, and you use [self makeToast:@"Hello World"], you're going to get an error. You need to use [self.view makeToast:@"Hello World"], which references the view property assigned to that controller, not the controller itself.

There's a few ways to do what you want. If you're using a UINavigationController, you can just display the toast in the navigation controller's container view. Then it doesn't matter if view controllers are being pushed/popped from the stack. You can do that like this:

[self.navigationController.view makeToast:@"Hello World"];

Another thing you can do is add the toast directly to the window (since UIWindow inherits from UIView). This is useful if you're not using a navigation controller:

[self.view.window makeToast:@"Hello World"];

Generally, it's bad practice to add something directly to the UIWindow unless you really need to so if you're using a navigation controller, use the first method. Hope that helps.

Thanks Charles! You're right, I did mean the view controller's view, not the view controller itself. I didn't think of using the navigation controller, good one!
