How to hide statusbar icons in iOS

I want to create a simple mobilesubstrate tweak that hides and shows status bar icons like battery or Carrier or wifi signal indecator. I've seen libstatusbar project but i can't find out how to hide iOS's icons. Is there any other way to do this without the use of this library? I just want to hide and show the default icons

Solution

  • Here is what I use in my tweak:

    int itemToHide = 0;
[[objc_getClass("SBStatusBarStateAggregator") sharedInstance] beginCoalescentBlock];
[[objc_getClass("SBStatusBarStateAggregator") sharedInstance] _setItem:itemToHide enabled:NO];
[[objc_getClass("SBStatusBarStateAggregator") sharedInstance] endCoalescentBlock];

    Only problem - iOS uses integer values for status bar items and they're different on different iOS versions. You could test every iOS version and store values for each one of them but I found a better way.

    I hook SBStatusBarStateAggregator _setItem:(int)arg1 enabled:(BOOL)arg2 method. Then I call one of the SBStatusBarStateAggregator -(void)_update**** methods. For example, let's say I want to find location icon index. I call SBStatusBarStateAggregator -(void)_updateLocationItem method. It then will call hooked SBStatusBarStateAggregator _setItem:(int)arg1 enabled:(BOOL)arg2 where I will store the index.

    I also hook SBStatusBarStateAggregator -(void)_notifyItemChanged:(int)arg. This method is called as part of SBStatusBarStateAggregator -(void)_update**** call. When determing status bar icon index I simply ignore calls to it by returning without calling original implementation.

    And if you want to permanently hide some of the icons you still need to hook SBStatusBarStateAggregator _setItem:(int)arg1 enabled:(BOOL)arg2 and SBStatusBarStateAggregator -(void)_notifyItemChanged:(int)arg in order to ignore any iOS attempts to show hidden icons. For example, signal level and data/time are reanabled every time they're updated.

    That's all for iOS 7. On iOS 5-6 API is different but I use pretty much the same approach. To hide status bar item

    int itemToHide = 0;
[[objc_getClass("SBStatusBarDataManager") sharedDataManager] setStatusBarItem:itemToHide enabled:NO];

    I hook SBStatusBarDataManager -(void)updateStatusBarItem:(int)item to determine icon index and then call SBStatusBarDataManager -(void)_locationStatusChange in case of location icon.
