如何使UIWindow透明化

Question

I need to see the HomeScreen from the UIWindow by making the UIWindow background as transparent. How to achieve this ?

I have tried with [UIColor ClearColor]; But its displaying BlackColor only.

Answer 1

It's not possible to see the homescreen inside your app. Apple did this to save power (who needs to render the homescreen while he's using an app) and to prevent devs from irritating users by making them think they are on their homescreen.

Answer 2

这是不好的，但它必要，然后我认为你使用像下面可能是用户的

self.window.backgroundColor = [UIColor colorWithRed:55.0f green:55.0f blue:55.0 alpha:0.05];
