swift - How to connect UITableViewCell button to perform UITableView functions? -


i have app utilizes tableview contains prototype cell. prototype cell contains few labels , button (connected cell's uitableviewcell file). if that's not clear, mean:

class contactscell: uitableviewcell { //this custom cell used prototype cell tableview      @iboutlet weak var firstnamelabel: uilabel!      @iboutlet weak var lastnamelabel: uilabel!      @iboutlet weak var numberlabel: uilabel!      @iboutlet weak var indexpathrowlabel: uilabel!      @iboutlet weak var replacecontactbuttonui: uibutton!      @ibaction func replacecontactbuttontapped(_ sender: any) {         //this button in question     }

the reason because i'd each cell in tableview have of labels (and button), each row having different values in labels. these values handled cellforrowat tableview function, via system follows:
pressing button (not button in cells talking about... different button @ top of vc, outside of tableview) brings contact picker:

 func selectcontact(){//allows user bring contactpicker          let contactpicker = cncontactpickerviewcontroller()         contactpicker.displayedpropertykeys = [cncontactgivennamekey, cncontactfamilynamekey, cncontactphonenumberskey, cncontactimagedatakey]          contactpicker.delegate = self          contactpicker.predicateforenablingcontact = nspredicate(format: "phonenumbers.@count >= 0")          contactpicker.predicateforselectionofcontact = nspredicate(format: "phonenumbers.@count >= 1")          self.present(contactpicker, animated: true, completion: nil)     }     @ibaction func selectcontactsbutton(_ sender: any) {         selectcontact()         //button brings picker allow selection of contact     }

selecting 1 of contacts updates array used tableview update value of labels:

func contactpicker(_ picker: cncontactpickerviewcontroller, didselect contactproperty: cncontactproperty) {     contactarray.append(contactproperty.contact)     print(contactarray)// contactarray = [cncontact]()     contactstableview.reloaddata()// reloads value of labels     dismiss(animated: true) }

these work intended. however, run bit of issue button in each cell. button intended allow replacement of cncontact in tableview @ row of button pressed... (ie if there 4 rows, there 4 "replace" buttons. clicking "replace" button of third row replaces cncontact @ 2nd index of contactarray). issue is, though. since button, , action, lives in uitableviewcell's swift file, , not in tableviewcontrollers, doesn't have access contactarray remove , append, nor picker functions allow selection of new contact, nor tableview run .reloaddata(). how 'give access' uitableviewcell's swift file utilize things tableview controller part of/connected to?
note possible entire premise of question wrong , should've placed button's action elsewhere (not in uitableviewcell's swift file). if case, should put it?

since have information in viewcontroller, suggest moving @ibaction viewcontroller well. if worried referencing correct cell, can set tag value of uibutton in cellforrow method. in @ibaction, can use value access correct index in array cell itself

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
