Um método sem parâmetros está chamando por um argumento
Eu tenho uma classe chamadaLocation
que possui vários métodos que não possuem parâmetros.
No entanto, quando tento criar uma variável com o resultado do método, ele quer um argumento. Por que é que?
Location
classe:
let locationManager = CLLocationManager()
public class Location {
public func coordinate() -> (latitude: Float?, longitude: Float?) {
let latitude = Float((locationManager.location?.coordinate.latitude)!)
let longitude = Float((locationManager.location?.coordinate.longitude)!)
return (latitude: latitude, longitude: longitude)
}
public func getCity() -> String {
var returnCity: String = "N/A"
let geoCoder = CLGeocoder()
let location = CLLocation(latitude: (locationManager.location?.coordinate.latitude)!, longitude: (locationManager.location?.coordinate.longitude)!)
geoCoder.reverseGeocodeLocation(location, completionHandler: { (placemarks, error) -> Void in
// Place details
var placeMark: CLPlacemark!
placeMark = placemarks?[0]
// City
if let city = placeMark.addressDictionary!["City"] as? String {
returnCity = city
}
})
return returnCity
}
public func getCountry() -> String {
var returnCountry: String = "N/A"
let geoCoder = CLGeocoder()
let location = CLLocation(latitude: (locationManager.location?.coordinate.latitude)!, longitude: (locationManager.location?.coordinate.longitude)!)
geoCoder.reverseGeocodeLocation(location, completionHandler: { (placemarks, error) -> Void in
// Place details
var placeMark: CLPlacemark!
placeMark = placemarks?[0]
// City
if let country = placeMark.addressDictionary!["Country"] as? String {
returnCountry = country
}
})
return returnCountry
}
public func getZip() -> Int {
var returnZip: Int = 0
let geoCoder = CLGeocoder()
let location = CLLocation(latitude: (locationManager.location?.coordinate.latitude)!, longitude: (locationManager.location?.coordinate.longitude)!)
geoCoder.reverseGeocodeLocation(location, completionHandler: { (placemarks, error) -> Void in
// Place details
var placeMark: CLPlacemark!
placeMark = placemarks?[0]
// City
if let zip = placeMark.addressDictionary!["ZIP"] as? Int {
returnZip = zip
}
})
return returnZip
}
public func getLocationName() -> String {
var returnName: String = "N/A"
let geoCoder = CLGeocoder()
let location = CLLocation(latitude: (locationManager.location?.coordinate.latitude)!, longitude: (locationManager.location?.coordinate.longitude)!)
geoCoder.reverseGeocodeLocation(location, completionHandler: { (placemarks, error) -> Void in
// Place details
var placeMark: CLPlacemark!
placeMark = placemarks?[0]
// City
if let locationName = placeMark.addressDictionary!["Name"] as? String {
returnName = locationName
}
})
return returnName
}
public func getStreetAddress() -> String {
var returnAddress: String = "N/A"
let geoCoder = CLGeocoder()
let location = CLLocation(latitude: (locationManager.location?.coordinate.latitude)!, longitude: (locationManager.location?.coordinate.longitude)!)
geoCoder.reverseGeocodeLocation(location, completionHandler: { (placemarks, error) -> Void in
// Place details
var placeMark: CLPlacemark!
placeMark = placemarks?[0]
// City
if let street = placeMark.addressDictionary!["Thoroughfare"] as? String {
returnAddress = street
}
})
return returnAddress
}
}
Tentando criar uma variável:
let city = Location.getCity()
Aqui estão algumas capturas de tela do que recebo:
