或者我可以直接打电话addGeofences而不删除旧的,并让新的替换旧的？

CLLocationManager startMonitoringForRegion:设备重启后不重新启动应用程序

好的,所以我目前有一个应用程序,我在其中注册使用该CLLocationManager startMonitoringForRegion方法监控的地理围栏.当应用程序位于前台和后台时,此工作正常.

我也有适当的plist值设置:

UIBackgroundModes :{location}
UIRequiredDeviceCapabilities: {location-services}

什么行不通

设备重启后,应用程序未重新启动.如果我startMonitoringSignificantLocationChanges在进入背景之前设置,我可以强制这种情况发生.但是这种方法使用了更多的电池寿命,而且我不需要这个位置,就在我打破地理围栏的时候.

各地区的文件说:

In iOS, the regions you register with the location manager persist between launches of your application. If a region crossing occurs while your iOS app is not running, the system automatically wakes it up (or relaunches it) in the background so that it can process the event. When relaunched, all of the regions you configured previously are made available in the monitoredRegions property of any location …

在Android中使用预览绘制圆形地理围栏

首先,我的问题与Android中gmap中有关GeoFencing的其他问题略有不同.

当用户开始将圆定义为地理栅栏区域时,我想在屏幕中央显示一个固定的圆圈.在此阶段,用户应该能够移动地图和地图的缩放级别.移动动作和放大/缩小动作都不能改变圆相对于屏幕的大小.

当用户按下保存按钮时,我想将该圆圈作为CircleOption对象固定到地图上.然后我将能够以米为单位获得CircleOption对象的lon/lat和radius.

我目前正在研究RelativeLayout问题.我按照预期绘制了一个带有RelativeLayout的固定圆,但是我无法获得该RelativeLayout圆的当前半径.您可以看到我的RelativeLayout现在的样子:

在此输入图像描述

我不确定这样做的正确方法.我的搜索重定向我使用RelativeLayout然后使用CircleOption.你有什么建议？

提前致谢!

地理围栏事件并不总是被称为

这是我添加地理围栏的方式:

public void setGeofenceRequest(Location location) {
    if (geofences == null) {
        geofences = new ArrayList<Geofence>();
    }
    geofences.add(new Geofence.Builder()
            .setRequestId("3")
            .setTransitionTypes(Geofence.GEOFENCE_TRANSITION_EXIT)
            .setCircularRegion(
                    location.getLatitude(), location.getLongitude(), PSLocationService.getInstance(context).kPSGeofencingDistanceMedium)
            .setExpirationDuration(Geofence.NEVER_EXPIRE)
            .build());
    Intent intent = new Intent(context, ReceiveTransitionsBroadcastReceiver.class);
    PendingIntent pi = PendingIntent.getBroadcast(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
    if (geofences.size() > 0) {
        LocationServices.GeofencingApi.addGeofences(mLocationClient, geofences, pi);
        Log.i("", "geof autopilot2 will set geofence for autopilot-3");
    }
}

这是我的BroadcastReceiver.我应该在哪里收到它们:

public class ReceiveTransitionsBroadcastReceiver extends BroadcastReceiver {

@Override
public void onReceive(Context ctx, Intent intent) {
    Log.i("","autopilot valid geof on receive transisionts broadcast receiver"); …
