ios打包后uni.getLocation无法获取定位信息的address
返回数据为{"type":"gcj02","latitude":39.049438,"longitude":117.701996,"speed":0,"accuracy":36,"errMsg":"getLocation:ok"}，里面没有需要的address信息，代码内也是设置了geocode为true的，如下

uni.getLocation({  
            type: 'gcj02',  
            geocode: true,  
            success: res => {  
                uni.showModal({  
                    title:'gcj02',  
                    content:JSON.stringify(res)  
                })  
            }                 
        });
