independent：true 。 之前分包 没用这个 ，昨天更新不知道有什么用，就写了一下，然后就发现真机调用时 独立分包里的东西 用不了app.wxss的样式

求助? 什么时候好

请问多少版本的才能显示

有两个问题:1,是不是在ios下,得到mac地址 只能将advertisData转成字符串,进行获取;                    2,相同的代码,将advertisData转为mac地址,,在下图中我们自己的蓝牙打印出来为空,;而其余搜索到的设备自打印出来了? 请问是什么情况?[图片]

[代码]wx.openLocation[代码] [代码][图片] [代码] 这个接口可以打开内置地图 然后点击绿色按钮 [图片] 可以弹出列表调用手机安装的地图app 那这个按钮的功能可以自己实现吗？就是比如自己定义一个按钮，然后点击弹出手机中的地图app然后选择调用。

为什么?????
