【问题描述】：

如何在小部件中获取用户当前位置？我正在使用 swiftUI。

【参考方案1】：

class WidgetLocationManager: NSObject, CLLocationManagerDelegate 
    var locationManager: CLLocationManager? 
    private var handler: ((CLLocation) -> Void)?

    override init() 
        super.init()
        DispatchQueue.main.async 
            self.locationManager = CLLocationManager()
            self.locationManager!.delegate = self
            if self.locationManager!.authorizationStatus == .notDetermined 
                self.locationManager!.requestWhenInUseAuthorization()
            
        
    
    
    func fetchLocation(handler: @escaping (CLLocation) -> Void) 
        self.handler = handler
        self.locationManager!.requestLocation()
    

    func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) 
        self.handler!(locations.last!)
    
    
    func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) 
        print(error)
    

打电话

var widgetLocationManager = WidgetLocationManager()

func getTimeline(for configuration: SelectPlaceIntent, in context: Context, completion: @escaping (Timeline<Entry>) -> Void) 
    widgetLocationManager.fetchLocation(handler:  location in
        print(location)
        .......
    )
