我有一个简单的问题,我找不到我需要的东西.

我需要计算商店列表的t2地理编码点之间的距离.我还需要将它分页为WebService.

这有效,但结果中没有距离:

public function stores(){
    return Store::paginate(10);
}

结果是:

{
   total: 4661, 
   per_page: 10, 
   current_page: 6, 
   last_page: 467,
   next_page_url: "WS_URL/stores/?page=7",
   prev_page_url: "WS_URL/stores/?page=5", from: 51,
   to: 60, 
   data: [ { 
        id: "51", 
        name: "Sprouts",
        .
        .
        lng: "-118.359688", 
        lat: "33.808281", 
        country: "usa" 
        },
    .
    .
    .
    ]}

但我需要这个代码工作:

public function stores(){
    return DB::table('stores')
        ->selectRaw(' *, distance(lat, ?, lng, ?) as distance ')
        ->setBindings([ 41.123401,1.2409893])
        ->orderBy('distance')
        ->paginate($this->limit);
}

这就是结果:

{total: 0,
    per_page: 10,
    current_page: 1,
    last_page: 0,
    next_page_url: null,
    prev_page_url: null, …

我有一个简单的问题:

我无法强制[UIApplication sharedApplication] openUrl: 打开网页导航器中的网址,始终打开Facebook应用程序,不要去facebook页面.
