ios - after toggling shouldAutorotate, orientation off -


i have worked on while , googled related can think of.

i have button in app toggles rotation. when turn rotation off, rotate device, turn rotation on, need way match app orientation device orientation. 

@interface viewcontroller () {     bool _rotationstatus; }

method tied button press:

   -(void)togglerotation     {         if(_rotationstatus == no)         {                     _rotationstatus = yes;         }         else         {             _rotationstatus = no;         }     }   - (bool)shouldautorotate //only targeting ios 6 {     return !_rotationstatus; }

this works great toggle rotation, when rotation turned on, orientation not "refresh" match device orientation until rotate device again.

for example

  1. device , app start in portrait.
  2. tap button toggle rotation off.
  3. rotate device landscape.
  4. device landscape, app portrait expected.
  5. tap button toggle rotation on

desired: app rotates landscape match device.

actual: app remains in portrait until rotation notification received.

i think way correct check device orientation, , check app orientation , match them when rotation toggled on.

i added method:

if ((uideviceorientationislandscape([uidevice currentdevice].orientation)) && ([[uiapplication sharedapplication] statusbarorientation] == uiinterfaceorientationportrait))         {             nslog(@"mis-matched device , app orientations");             //do rotation?             [[uiapplication sharedapplication] setstatusbarorientation: uiinterfaceorientationlandscaperight animated:yes];         }

so full method looks this. 

-(void)togglerotation {         if(_rotationstatus == no)         {                     _rotationstatus = yes;         }         else         {             _rotationstatus = no;              if ((uideviceorientationislandscape([uidevice currentdevice].orientation)) && ([[uiapplication sharedapplication] statusbarorientation] == uiinterfaceorientationportrait))           {               nslog(@"mis-matched device , app orientations");               //do rotation?               [[uiapplication sharedapplication] setstatusbarorientation: uiinterfaceorientationlandscaperight animated:yes];           }         } }

the nslog prints when expect to, call setstatusbarorientation not result in rotation.

i'm ios rookie, sure doing many things wrong. there better way this?
