i want change marker image in mkpointannotation() , have changed image problem have 2 marker points , want place ignitionon.png on point 1 , ignitionof.png on point 2 , logic place ignitionon.png on both points.
code
if(self.doubellocation) { var pointoff = cllocationcoordinate2d() var pointon = cllocationcoordinate2d() if(self.datetime.count > 0) { for(var : int = 0 ; < self.datetime.count ; i++) { // print("real status = \(self.datetime[i])") var fixtime = self.datetime[i] if(fixtime == self.datetimetwo) { pointoff = cllocationcoordinate2dmake(self.latt[i], self.lngg[i]); print("pointoff = \(pointoff)") //points.append(pointof) } if(fixtime == self.datetimeone){ pointon = cllocationcoordinate2dmake(self.latt[i], self.lngg[i]); print("pointon = \(pointon)") //points.append(pointof) } } var points: [cllocationcoordinate2d] points = [pointon, pointoff] dispatch_async(dispatch_get_main_queue(), { let geodesic = mkgeodesicpolyline(coordinates: &points[0], count: 2) self.themapview.addoverlay(geodesic) let latdelta:cllocationdegrees = 0.03 let lnggdelta:cllocationdegrees = 0.03 uiview.animatewithduration(1.5, animations: { () -> void in let span = mkcoordinatespanmake(latdelta, lnggdelta) let region1 = mkcoordinateregion(center: points[0], span: span) self.themapview.setregion(region1, animated: true) self.activityindicator.stopanimating() for(var : int = 0 ;i < points.count; i++){ var st = self.reporttext[i] // let themarker = mkpointannotation() //how change marker color //https://stackoverflow.com/questions/33532883/add-different-pin-color-with-mapkit-in-swift-2-1 let themarker = mkpointannotation() themarker.coordinate = points[i] // if(st == "ignition on"){ if(i == 0){ themarker.title = "status : ignition off" themarker.subtitle = "\(self.locationoff)" // themarker.subtitle = "date = , reg#: " self.themapview.addannotation(themarker) let anview1:mkannotationview = mkannotationview() anview1.annotation = themarker anview1.image = uiimage(named:"ignitionof") anview1.canshowcallout = true anview1.enabled = true } if(i == 1){ // themarker = uicolor.greencolor() themarker.title = "status : ignition on" themarker.subtitle = "\(self.locationon)" // themarker.subtitle = "date = , reg#: " self.themapview.addannotation(themarker) //how change image of marker //https://stackoverflow.com/questions/24467408/swift-add-mkannotationview-to-mkmapview let anview:mkannotationview = mkannotationview() anview.annotation = themarker anview.image = uiimage(named:"ignitionon") anview.canshowcallout = true anview.enabled = true } // } } }) }) } } func mapview(mapview: mkmapview, viewforannotation annotation: mkannotation) -> mkannotationview? { if (annotation mkuserlocation) { //if annotation not mkpointannotation (eg. mkuserlocation), //return nil map draws default view (eg. blue dot)... return nil } let reuseid = "test" var anview = mapview.dequeuereusableannotationviewwithidentifier(reuseid) if anview == nil { anview = mkannotationview(annotation: annotation, reuseidentifier: reuseid) anview!.image = uiimage(named:"ignitionon") anview!.canshowcallout = true } var anview1 = mapview.dequeuereusableannotationviewwithidentifier(reuseid) if anview1 == nil { anview1 = mkannotationview(annotation: annotation, reuseidentifier: reuseid) anview1!.image = uiimage(named:"ignitionof") anview1!.canshowcallout = true } else { //we re-using view, update annotation reference... anview!.annotation = annotation } return anview } i following link: swift - add mkannotationview mkmapview
it's not best way handle multiple marker different metadata. can't use mapview.dequeuereusableannotationviewwithidentifier(reuseid) 2 times or more because in viewforannotation 1 view each point have added in stack.
create sub-class of mkpointannotation:
class custompointannotation: mkpointannotation { var tag: string! } create dictionary images:
var imagespath : ["tag_1": "image_1.png", "tag_2": "image_2.jpg"] now in delegate func, check simply
if !(annotation custompointannotation) { return nil } and handle 1 view have:
let reuseid = "test" var anview = mapview.dequeuereusableannotationviewwithidentifier(reuseid) if anview == nil { anview = mkannotationview(annotation: annotation, reuseidentifier: reuseid) var customannotation = annotation as! custompointannotation anview!.image = uiimage(named: imagespath(customannotation.tag)) anview!.canshowcallout = true } an example add new custom point is:
let apoint = custompointannotation() apoint.coordinate = cllocationcoordinate2dmake(40.730872, -73.003066) apoint.title = "info1" apoint.subtitle = "subtitle" apoint.tag = "tag_1" mapview.addannotation(apoint)
