ios - Swift - overriding existing objc method in extension -


so, thought i'm quite familiar swift, turns out, i'm not.

i'm trying create uinavigationcontroller , uiviewcontroller extensions , override methods simplify control on device rotation.

so, found it's still possible in swift: https://stackoverflow.com/a/28220616/982550 don't want create base uiviewcontroller class thought follow same approach in obj-c:

extension uinavigationcontroller {  public override func supportedinterfaceorientations() -> uiinterfaceorientationmask {     return topviewcontroller!.supportedinterfaceorientations() }  public override func shouldautorotate() -> bool {     return topviewcontroller!.shouldautorotate() }  override public func preferredinterfaceorientationforpresentation() -> uiinterfaceorientation {     return topviewcontroller!.preferredinterfaceorientationforpresentation()      } }  extension uiviewcontroller {  public override func supportedinterfaceorientations() -> uiinterfaceorientationmask {     return .portrait }  public override func shouldautorotate() -> bool {     return false }  override public func preferredinterfaceorientationforpresentation() -> uiinterfaceorientation {     return .portrait     } }

but doesn't compile xcode 7.2.1 , swift 2.1, got:

: method 'supportedinterfaceorientations()' objective-c selector 'supportedinterfaceorientations' conflicts previous declaration same objective-c selector

i guess there no way around it, both class subclasses of uiviewcontroller can't make 2 extensions same methods?

i have following table, select records should have mentioned values. example select companyid should have 3 providerid 200,300,400. running query should retrun companyid 2. opposite of in . in advance ! companyid | providerid -------------------------------------- 1 100 2 200 3 500 4 600 2 300 2 400 7 100 do group by , select rows of 3 wanted employeeid values. use having make sure 3 different employeeid values. select companyid tablename employeeid in (200, 300, 400) group companyid having count(distinct employeeid) = 3 another approach double self join, 1 each employeeid. however, less flexible: select distinct t1.companyid (select companyid tablename employeeid = 200) t1 join (select companyid tablename employeeid = 300) t2 on t1.companyid = t2.companyid join (select companyid tablename employeeid = 400)...
