地理位置代码不适用于iPhone/iPod Touch/iPad

Question

我们在Apple Store进行了一些测试，发现我们的地理位置代码（获取经度和纬度）不适用于iPhone，iPod Touch或iPad。我确实需要添加额外的代码才能使其适用于MacBook/iMac。

任何人都知道获取经纬度在iPod Touch/iPhone/iPad设备上有效的代码吗？

我写的库。如果你真的只对iOS的部署，那么你可以简单地使用基本JavaScript和完全绕过库：

navigator.geolocation.getCurrentPosition(foundLocation, noLocation); 

function foundLocation(position) 
{ 
var lat = position.coords.latitude; 
var long = position.coords.longitude; 
alert('Found location: ' + lat + ', ' + long); 
} 
function noLocation() 
{ 
alert('Could not find location'); 
}
