引用第三方地图定位之后用reverseGeocode()转码，ios报-100

map.getUserLocation(function(state,pos){
if(0==state){
map.setCenter(pos);
var point = new plus.maps.Point(JSON.stringify(pos.longitude),JSON.stringify(pos.latitude));
mui.alert(point);
plus.maps.Map.reverseGeocode(point,{},function(event){
var address = event.address; // 转换后的地理位置
var point = event.coord; // 转换后的坐标信息
var coordType = event.coordType; // 转换后的坐标系类型
$("#address").html('您当前的位置是:'+address);
mui.ajax("",{
data:{
flag:3,
aflag:aflag,
time:now,
phone_id:plus.device.uuid,
