//解決位置偏移
var loadCount = 1;
        map.addEventListener("tilesloaded",function() {
            if (loadCount == 1) {
                map.setCenter(point);
            }
            loadCount = loadCount + 20;
        })

var loadCount = 1;
map.addEventListener("tilesloaded",function() {
    if (loadCount 
 
== 1) {
        map.setCenter(point);
    }
    loadCount = loadCount + 20;
})

加載百度地圖之後 中心為位置有點偏移
