ios - supportedInterfaceOrientations not called in iPad -


i have uitabbarcontroller subclass , has below code:

class tabbarcontroller: uitabbarcontroller {  // mark: methods  override func viewdidload() {      super.viewdidload()  }  override func supportedinterfaceorientations() -> uiinterfaceorientationmask {      print(self.selectedindex)     if self.selectedindex == 1 {         return .portrait     }      return .all      }  }

the function supportedinterfaceorientations called when execute app iphone. if execute app ipad mini not called. idea of reason of behaviour?

it strange, if deselect upside down device orientation ipads supportedinterfaceorientations called.

enter image description here

update:

if 'requires full screen' setting 'general' enable, allow orientation delegate methods shouldautorotate, preferredinterfaceorientation, , supportedinterfaceorientations fire.

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac
