swift5 使用未声明的类型 'CLLocaitonDegress'

Question

我试图从我的应用程序中获取纬度和经度的值。但是“使用未声明的类型'CLLocaitonDegress'”这个消息有一些错误.. 我不明白我的代码发生了什么？？

func fetchWeather(latitude: CLLocaitonDegress, longitude: CLLocationDegrees) {
        let urlString = "\(weatherURL)&lat=\(latitude)&lon=\(longitude)"
        performRequest(urlString: urlString)
    }

//MARK: -CLLocationManagerDelegate

extension WeatherViewController: CLLocationManagerDelegate {
    func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        if let location = locations.last {
            let lat: Double = location.coordinate.latitude
            let lon: Double = location.coordinate.longitude
            weatherManager.fetchWeather(cityName: String, latitude: lat, longitude: lon)
        }
    }
    
    func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
        print("error")
    }
    
}

Answer 1

您需要在 import UIKit 下添加 import CoreLocation

import UIKit
import CoreLocation

Answer 2

在你的代码中替换： func fetchWeather（纬度：CLLocaitonDegress，经度：CLLocationDegrees）

有了这个：

func fetchWeather（纬度：CLLocationDegrees，经度：CLLocationDegrees）

swift5 使用未声明的类型 'CLLocaitonDegress'

swift5 Use of undeclared type 'CLLocaitonDegress'

swift

cllocationmanager

swift5

cllocation
