ios - TableView Inside a UITableViewCell - must register a nib or class -


i'm putting uitableview inside uitableviewcell.

i've extended class of uitableviewcell ,uitableviewdatasource, uitableviewdelegate.

made @iboutlet var tableview: uitableview!

added following:

override init(style: uitableviewcellstyle, reuseidentifier: string?) {         super.init(style: style , reuseidentifier: reuseidentifier)         setuptable()     }      required init(coder adecoder: nscoder) {         super.init(coder: adecoder)!         setuptable()     }      override func awakefromnib() {         super.awakefromnib()         setuptable()     }

where setuptable() implemented as:

func setuptable(){         tableview?.delegate = self         tableview?.datasource = self         //tableview.register(uinib(nibname: "availabletimingstableviewcell", bundle: nil), forcellreuseidentifier: "timingcell")     }

if keep commented line in setuptable() get:

'unable dequeue cell identifier timingcell - must register nib or class identifier or connect prototype cell in storyboard'

if uncomment comment get:

fatal error: unexpectedly found nil while unwrapping optional value

on same line.

after setuptable() i've implemented them as:

func tableview(_ tableview: uitableview, numberofrowsinsection section: int) -> int {         return 3     }      func numberofsectionsintableview(tableview: uitableview) -> int {         return 1     }      func tableview(_ tableview: uitableview, cellforrowat indexpath: indexpath) -> uitableviewcell {          let cell = tableview.dequeuereusablecell(withidentifier: "timingcell", for: indexpath) as?availabletimingstableviewcell          cell?.daynamelabel.text = "wednesday"         cell?.timelabel.text = "01:00 pm - 03:00 pm"          return (cell)!     }

edit here screenshots of class names. i've double checked okay per comments , answer.

i think setuptable() in init() called soon. @ point view not loaded. setup in viewdidload(), don't comment out registering cell. other code looks good.

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
