如何在 Apple Watch 中集成苹果地图？

Question

我是 Apple Watch 开发的新手，想在 Apple Watch 中集成苹果地图，它只想显示我的当前位置，但每次我在模拟器中加载界面时，我都会得到如下所示的屏幕。任何帮助都将不胜感激。

   -(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations
    {
        CLLocation* loc = [locations lastObject];
        CLLocationCoordinate2D myLocationCoordinate2D = loc.coordinate;
        [self.demoMap setRegion:MKCoordinateRegionMake(myLocationCoordinate2D, MKCoordinateSpanMake(0.0,0.0))];//set map region
        [self.demoMap addAnnotation:myLocationCoordinate2D withPinColor:WKInterfaceMapPinColorGreen];// set pin on map
        [locationManager stopUpdatingLocation];
    }

#pragma mark - CLLocation Manager

-(void)startTrackingCurrentLcoation:(BOOL)forTrip
{
    locationManager = [[CLLocationManager alloc] init];
    locationManager.delegate = self;
    locationManager.desiredAccuracy = kCLLocationAccuracyBest;
    [locationManager requestAlwaysAuthorization];

    CLAuthorizationStatus status = [CLLocationManager authorizationStatus];
    if (status == kCLAuthorizationStatusAuthorizedAlways || status == kCLAuthorizationStatusAuthorizedWhenInUse)
    {
        NSLog(@"%@ Start tracking current location", self);
        [locationManager startUpdatingLocation];


    }
}
-(void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status
{
    status = [CLLocationManager authorizationStatus];
    if (status == kCLAuthorizationStatusDenied)
    {
        NSString *message = @"To use background location you must turn on 'Always' in the Location Services Settings";
        NSLog(@"%@",message);
    }
    else if (status == kCLAuthorizationStatusNotDetermined)
    {
        [locationManager requestAlwaysAuthorization];
    }
    else
    {
        [locationManager startUpdatingLocation];
    }

}

Answer 1

我自己试了一下，里面有很多陷阱。

我破解了一个演示项目，您可以在这里找到它： https://github.com/sticksen/WatchKit-Map-Sample-Project

清单：

务必请求定位服务授权并在用户授予访问权限后开始更新位置。

如果已获得授权，您可以立即开始更新位置

现在最糟糕的部分是：

您的主要目标（不是 WatchKit 目标，只是为了说明清楚！）Info.plist 必须有一个名称为 NSLocationWhenInUseUsageDescription 或 NSLocationAlwaysUsageDescription 的密钥（取决于您请求的授权）作为值有一个描述字符串，说明您为什么要使用定位服务。如果不在 Info.plist 中设置此键，它将无法工作 !

通过给定预定义的坐标，检查您获取传递给 region.Test 的当前位置坐标的天气情况。
