ios - Can't get correct city name in swift with CLGeocoder -

-

i tried current city name , country name swift. here's source code. // in cllocationmanagerdelegate method can user's current location coordinates:

func locationmanager(manager: cllocationmanager, didupdatelocations locations: [cllocation]) {     let locvalue:cllocationcoordinate2d = manager.location!.coordinate     print("locations = \(locvalue.latitude) \(locvalue.longitude)")     self.locationmanager.stopupdatinglocation()     getaddressfromgeocodecoordinate(manager.location!)  }  func getaddressfromgeocodecoordinate(locationobj: cllocation) {     let geocoder = clgeocoder()     geocoder.reversegeocodelocation(locationobj, completionhandler: { (placemarks, error) -> void in          // place details         var placemark: clplacemark!         placemark = placemarks?[0]          // address dictionary         print(placemark.addressdictionary)          // city         if let city = placemark.addressdictionary!["city"] as? nsstring {             print("city:",city)         }          // country         if let country = placemark.addressdictionary!["country"] as? nsstring {             print("country", country)         }      }) }

but when want print city returns nil. trid placemark.subadministrativearea returns nil.

i'm located in dandong city.

my code prints country well. country china city.

anybody knows solution?

check if error or what's response of getting print(placemark.addressdictionary)

geocoder.reversegeocodelocation(newlocation, completionhandler: {(stuff, error)->void in          if error {             println("reverse geodcode fail: \(error.localizeddescription)")             return         }          if stuff.count > 0 {             self.placemark = clplacemark(placemark: stuff[0] clplacemark)              self.addresslabel.text = string(format:"%@ %@\n%@ %@ %@\n%@",                 self.placemark.subthoroughfare ? self.placemark.subthoroughfare : "" ,                 self.placemark.thoroughfare ? self.placemark.thoroughfare : "",                 self.placemark.locality ? self.placemark.locality : "",                 self.placemark.postalcode ? self.placemark.postalcode : "",                 self.placemark.administrativearea ? self.placemark.administrativearea : "",                 self.placemark.country ? self.placemark.country : "")         }         else {             println("no placemarks!")             return         }          })

Deploying Qt Application on Android is really slow? -

-
as may know there 3 ways deploy qt application on android : use ministro service install qt deploy local qt libraries temporary directory bundle qt libraries in apk the first method takes 30 seconds , needs install apk . ministro . second takes 1 minute me ! , anytime try run program qt creator pushes qt libraries device. third 1 makes .apk file big , again takes 1 minute me. think situation that's not reasonable develop android application using qt. there way make deploying process faster? almost full year since op , things have not changed @ all. deployment of 7 mb apk takes on minute , half project compiles in 5 seconds. reason answering not problem got resolved, offer alternative solution. i've implemented "workaround" consisting of 2 applications work in tandem - 1 on pc , 1 on device - created compile files remotely, turned out faster alternative deployment well. on host create application launches compilation in separate process, when do...
