问题 I'm wondering if it's possible to customize in app alerts with the UIAlertController. I haven't seen anything that explicitly says that you can. Does anyone know of a way I can add a custom appearance, particularly with fonts on these alerts? 回答1: You can do it with appearanceWhenContainedIn. To set up background color, here's an example: [[UIView appearanceWhenContainedIn:UIAlertController.class, nil] setBackgroundColor:[UIColor yellowColor]]; Or tint color: [[UIView

I find that in some of my views where I have custom inputView property set on a text field, the Swype keyboard is overriding and presenting instead of my picker. This completely breaks my UI and cannot be allowed. Is there a way to explicitly tell iOS 8 only to use the inputView I have set? Is this a bug, perhaps? It is not at all expected behavior to allow a third party to override my input spec?

问题 My app utilizes UIVisualEffectView to blur the background just like Control Center. But I discovered the iPad 2 (and Retina iPad) which can run iOS 8 isn't powerful enough to display that effect so it reverts to a gray color. I would like to be able to detect if the device the app is running on is powerful enough to display the blur effect, and if not I won't apply it, instead I'll change the background color to something that looks much better than that gray color. But I don't want to just
