iPhone在状态栏中添加图标（电池指示灯）

Question

I was wondering if it is possible to add an icon to the iPhone status bar, much like the battery and wifi indicator. How can I do this?

Thanks.

Answer 1

As previously reported, it's not possible to do so with the SDK.

If you're working for a jailbroken environment, status bar icons need to be placed within /System/Library/CoreServices/SpringBoard.app with two versions: Default_NAME.png and FSO_NAME.png. Default is used in the light menubar-like status bar, FSO on the home screen or apps that use the black status bar.

SBStatusBarController has a method called addStatusBarItem:, just call it with @"NAME" as your argument and it will handle the rest for you.

Answer 2

Since it is not even possible to access the status bar directly, I wouldn't think so. You can only indirectly set a few of the status bar's properties through UIApplication, the displayed icons are not one of them. Everything else is Apple's turf.

Answer 3

It is not possible to do this. The UIApplication class gives you some limited controls over appearance. You may want to file an enhancement request with Apple Bug Reporter .

Answer 4

you can't do it in the sdk, plus apple would pitch a hissy fit if somebody was able to do it. I know there's a way to do it with the jailbroken tools, but I don't think I should discuss that stuff here as there are other sites that discuss it
