Customize iPhone app taskbar

Question

I thought it was not allowed to customize the taskbar on the iPhone. However, I noticed this application called iHandy Tip Calculator, which replaces the battery icon with a quick switch icon, which displays the view as shown. How is this permitted, and if so, how can I do something else?

Answer 1

If you run the application on the iPad, you will see how they do it: they overlap the usual status bar. Also note that screenshots in the app store do not show this feature. I assume that they were afraid to reject and disable the overlay for screenshots.

Answer 2

In a full-screen application, you can create your own status bar and "simulate" network status and battery life, etc. But the apple does not allow this, but it may be the one that “slipped”, as Gaz_Edge said.

Answer 3

Applications from this iHandy developer include this in the status bar, but I have never seen another company do this. I am surprised that the status bar can be changed this way anyway.

Answer 4

You're right. You should not be able to change the “springboard”. Apple usually refuses applications that do everything that modifies it. Maybe this one slipped through the net?

Answer 5

I just downloaded the latest version of iHandy Level (version 1.62.0) on an iPhone 5 running iOS 6, but I don’t see the icon (it’s in the application, not in the status bar). (And the status bar is hidden.)

I was curious to see if they really hid the status bar and created their own status bar. If that were the case, you could say, because when you scroll to the top of the notification center, a small tab will appear first, after which you will have to swipe the menu again with your finger.

Perhaps they removed this functionality at the request of Apple.

If anyone else has a version showing it, let us know if it displays a tab when you slide your finger over the center of notifications. If not, most likely they will find some private api so that they can replace their battery icon (which would be interesting).
