ios - How to change height of Annotation callout window Swift -

how change size of annotation callout window on map in swift. tried make bigger cgsize on each of component of right , left view without success height of view in end still same.

here code:

func mapview(mapview: mkmapview, viewforannotation annotation: mkannotation) -> mkannotationview? {      print("delegate called")      if !(annotation custompointannotation) {         return nil     }      let reuseid = "test"      var anview = mapview.dequeuereusableannotationviewwithidentifier(reuseid)     if anview == nil {         anview = mkannotationview(annotation: annotation, reuseidentifier: reuseid)            selectedustanova = (annotation as! custompointannotation).ustanova           anview!.canshowcallout = true     }     else {         anview!.annotation = annotation     }      //set annotation-specific properties **after**     //the view dequeued or created...      let cpa = annotation as! custompointannotation     anview!.image = uiimage(named:cpa.imagename)     return anview } func mapview(mapview: mkmapview, didselectannotationview view: mkannotationview) {     let button : uibutton = uibutton(type: uibuttontype.custom) uibutton     let image = uiimage(named: "telephone")     button.layer.cornerradius = 10     button.layer.backgroundcolor = uicolor.whitecolor().cgcolor     button.layer.maskstobounds = true     button.setbackgroundimage(image, forstate: uicontrolstate.normal)     button.frame = cgrectmake(0, 0, 35, 200)     button.addtarget(self, action: "buttonclicked:", forcontrolevents: uicontrolevents.touchupinside)       let labeltitle :   uilabel = uilabel(frame: cgrectmake(20,0,150,50))     labeltitle.text = selectedustanova!.ime     let labelsubtitle :   uilabel = uilabel(frame: cgrectmake(20,50,150,100))     var ustanovaopis = ""     if selectedustanova!.opis != nil{         ustanovaopis+=selectedustanova!.opis!+"\n"     }     if selectedustanova!.telefon != nil{         ustanovaopis+=selectedustanova!.telefon!     }     labelsubtitle.text = ustanovaopis     let leftcav : uiview = uiview(frame: cgrectmake(0,0,250,250));     let leftcav2: uiview = uiview(frame: cgrectmake(0,0,250,250));     let imageb = uiimage(named: "bigbutton")     let imageview : uiimageview = uiimageview(frame: cgrectmake(0,0,300,300))     imageview.image = imageb;     leftcav.addsubview(imageview)     leftcav.addsubview(labeltitle)     leftcav.addsubview(labelsubtitle)     view.leftcalloutaccessoryview = leftcav;     view.rightcalloutaccessoryview = leftcav2; } 

is there chance of making view bigger tried changing sizes of left , right callout accessory view without success far.

if interested in changing height of annotation callout here simple way. , making height 200 units.

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!.pintintcolor = uicolor.blackcolor()     }      pinview!.detailcalloutaccessoryview = self.configuredetailview(pinview!)     return pinview }  func configuredetailview(annotationview: mkannotationview) -> uiview {     let snapshotview = uiview()     let views = ["snapshotview": snapshotview]     snapshotview.addconstraints(nslayoutconstraint.constraintswithvisualformat("v:[snapshotview(200)]", options: [], metrics: nil, views: views))     //do work      return snapshotview }
