我有一张带有地图的sencha touch 2应用程序：
xtype: "map",
mapOptions: {
zoom: 11,
center: new google.maps.LatLng(51.516357, -0.113234),
navigationControl: true,
navigationControlOptions: {
style: google.maps.NavigationControlStyle.DEFAULT
}
}
当我使用它时，这工作正常，但是当我对任何类型使用sencha app build时，地图将显示其位于Palo Alto附近的位置作为中心而不是我给它的坐标。没有错误抛出。
答案 0 :(得分：3)
我从sencha更新了map.js。现在它的工作正常！ （touch / src / Map.js）
