i have uitableviewcell, has map view subview. created custom class handles actions adding annotations, delegates etc , named customemap.swift.
after changed class name of map view customemap in cell xib, app crashes times @ initwithcoder method of customemap because have not implemented method. later added method below:
import uikit import mapkit protocol customemapdelegate{ func annotationclickevent(info:nsdictionary?) } class customemap: mkmapview,mkmapviewdelegate,cllocationmanagerdelegate { var locationmanager:cllocationmanager? var delegate1:customemapdelegate? var tap:uitapgesturerecognizer? required init(coder adecoder: nscoder) { super.init(coder: adecoder) } override func awakefromnib() { if cllocationmanager.authorizationstatus() == clauthorizationstatus.authorizedalways { self.showsuserlocation = true; } else { locationmanager = cllocationmanager() locationmanager?.delegate = self; if locationmanager!.respondstoselector("requestalwaysauthorization") { locationmanager?.requestalwaysauthorization() } } self.delegate = self self.userinteractionenabled = true tap = uitapgesturerecognizer(target: self, action: "calloutaction:") } func locationmanager(manager: cllocationmanager!, didchangeauthorizationstatus status: clauthorizationstatus) { if(status == clauthorizationstatus.authorizedalways) { self.showsuserlocation = true; } } func skiptouch() { } class func createannotationfordict(temp:nsdictionary)->mypointannotation { var venue = temp.valueforkey("venue") as? nsdictionary var lat = venue!.valueforkey("latitude") as! double var lon = venue!.valueforkey("longitude") as! double var venuename = venue!.valueforkey("name") as! string var dealname = temp.valueforkey("title") as? string var coord:cllocationcoordinate2d = cllocationcoordinate2d(latitude: 0, longitude: 0) coord.latitude = lat coord.longitude = lon var point = mypointannotation() point.userinfo = temp point.coordinate = coord point.title = dealname point.subtitle = venuename return point } func mapview(mapview: mkmapview!, viewforannotation annotation: mkannotation!) -> mkannotationview! { if annotation mkuserlocation { return nil } let reuseid = "pin" var pinview = mapview.dequeuereusableannotationviewwithidentifier(reuseid) as? mkpinannotationview if pinview == nil { pinview = mkpinannotationview(annotation: annotation, reuseidentifier: reuseid) pinview!.canshowcallout = true pinview!.animatesdrop = true pinview!.pincolor = .red var assimg = uiimageview(image: uiimage(named: "r_arrow_g")) assimg.frame = cgrectmake(0, 0, 16, 16) assimg.contentmode = uiviewcontentmode.scaleaspectfit pinview!.rightcalloutaccessoryview = assimg } else { pinview!.annotation = annotation } return pinview } func mapview(mapview: mkmapview!, didselectannotationview view: mkannotationview!) { if view.annotation.iskindofclass(mkuserlocation){ return } if let t1 = tap { } else { tap = uitapgesturerecognizer(target: self, action: "calloutaction:") } view.addgesturerecognizer(tap!) } func mapview(mapview: mkmapview!, diddeselectannotationview view: mkannotationview!) { if view.annotation.iskindofclass(mkuserlocation){ return } view.removegesturerecognizer(tap!) } func calloutaction(sender:uitapgesturerecognizer) { if(delegate1 != nil) { var view = sender.view as! mkannotationview var ann = view.annotation as! mypointannotation delegate1!.annotationclickevent(ann.userinfo) } } } but still same issue.

it looks subclass messing original initialization methods. docs mkmapview should not subclass, use delegate need.
although should not subclass mkmapview class itself, can information map view’s behavior providing delegate object.
i suggest create custom uiview subclass, contains mkmapview , acts delegate. first step i'd take try resolve this.
