IOS plus.maps.drivingSearch不能进入onRouteSearchComplete

安卓端没问题,IOS端几十次能对个一两次

var searchObj = new plus.maps.Search();
searchObj.onRouteSearchComplete = function ( state, result ) {
console.log(JSON.stringify(result))
if ( state == 0 ) {

          } else {  
              uni.showToast({  
                title:"检索失败",  
                icon:"none"  
              })  
              uni.hideLoading();  
          }  
        }   
        searchObj.drivingSearch(new plus.maps.Point(_this.longitude,_this.latitude), "", new plus.maps.Point(_this.harvestAdd.split(",")[0],_this.harvestAdd.split(",")[1]), "" );
