cocoa touch - iOS 8 bug with navigation stack / rotation? -

i have 3 uiviewcontrollers: vc1, vc2, , vc3 appear in succession on uinavigationcontroller. vc1 has next rotation properties:

- (bool)shouldautorotate { homecoming yes; } - (bool) shouldautorotatetointerfaceorientation:(uiinterfaceorientation)tointerfaceorientation { homecoming (tointerfaceorientation == uiinterfaceorientationportrait); } - (nsuinteger)supportedinterfaceorientations { homecoming uiinterfaceorientationmaskportrait; } - (uiinterfaceorientation)preferredinterfaceorientationforpresentation { homecoming uiinterfaceorientationportrait; }

while vc2 , vc3 have next rotation properties:

- (bool)shouldautorotate { homecoming yes; } - (bool) shouldautorotatetointerfaceorientation:(uiinterfaceorientation)tointerfaceorientation { homecoming (tointerfaceorientation != uiinterfaceorientationportraitupsidedown); } - (nsuinteger)supportedinterfaceorientations { homecoming uiinterfaceorientationmaskallbutupsidedown; } - (uiinterfaceorientation)preferredinterfaceorientationforpresentation { homecoming self.presentedviewcontroller.interfaceorientation; }

while on vc3 (which preceded vc1 , vc2 on navigation stack of course), if user pushes restart button, want take them vc1:

- (void) restartbuttonpushed { [self.navigationcontroller poptorootviewcontrolleranimated:yes]; }

this works, if i'm in landscape mode on vc3, when force restart take me vc1 in landscape mode. whereas in < ios8, vc1 forced portrait mode. bug in ios8? or perchance fixed in ios8 exposed how doing wrong way?

interesting side note, if force restart button while in landscape mode , on vc2, works should, vc1 forced portrait mode.

ios8 - iOS custom keyboard - preserve state between appearances - i'm having performance problems custom keyboard i'm working on. loading words in spell correction tree takes quite bit of time. seems done each time keyboard appears - there way preserve state of keyboard? apps can suspend / resume etc - can't find documentation on how extensions, or if there's mechanism doing att all. thanks! you loading dictionary net or disk? first case nsuserdefaults, encoding (nscopying) options store info. can load in background. according docs, os typically kills extension process, so, think there no way prevent keyboard objects deallocation (you may utilize nskeydarchiver). ios8 ios-app-extension custom-keyboard
