ios - supportedInterfaceOrientations is not called in my controller -

i have complex problem (or think). i'm working on legacy application fixing issues, , making support 4 inch displays , ios 7. problem app's architecture quiet complex, several categories , method swizzling implement custom , feel in ios 4.3 , 5.

the application related financial markets , stock exchanges. app designed being navigated in portrait orientation only, except couple of controllers, tilting phone change view chart of stock/market. whole app has 1 uinavigationcontroller, , in many places, uitabbarcontrollers. in controller i'm interested in, structure follows:

• uinavigationcontroller
  • orientation controller changes view if orientation changed
    • uitabbarcontroller having several uiviewcontrollers
      • market/stock controller in first slot of uitabbarcontroller
    • chart controller

this structure used work this. when phone tilted, shouldautorotatetointerfaceorientation:(uiinterfaceorientation)interfaceorientation (this pre ios 6) called on orientation controller (that has both uitabbarcontroller , chart controller), , checks if selectedindex of uitabbarcontroller 1 market controller, or stock controller, replaces view chart view landscape orientation.

after ios 6, supportedinterfaceorientations , shouldautorotate added our code, , worked fine well. however, after upgrading xcode 5 , building ios 7 base sdk, shouldautorotate not being called on orientation controller, it's being called on both uitabbarcontroller , market/stock controller.

any ideas?

subclass navigation controller , override method:

// customnavigationcontroller.m  - (bool)shouldautorotate {     return [self.topviewcontroller shouldautorotate]; } 

then add shouldautorotate method viewcontroller should rotated , return yes:

// viewcontroller.m  - (bool)shouldautorotate {     return yes; }
