swift - Uibutton传递位置信息并开始快速在 map 上导航

Question

我有 CLLocationcooridinate2d 和位置详细信息的数组内容。我把它放在带有 Uibutton 的 tableview 单元格上，我所做的是试图通过 Uibuttom 传递特定的单元格信息并启动 map View 的新 View 并开始导航。这是我的代码:

   var tripspot:[tripSpot] = [
    tripSpot( title: "一中商圈", coordinate: CLLocationCoordinate2DMake(24.149062, 120.684891), regionRadius: 300.0, location: "台中市北區一中街", type: "Food",cllocation:CLLocation(latitude: 24.181143,  longitude: 120.593158))


 func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier("MapCell") as! mapTableViewCell
    if  searchController.active{
    cell.title.text = searchResults[indexPath.row].title
    cell.location.text = searchResults[indexPath.row].location
    cell.naviButton.tag = indexPath.row
    cell.naviButton.addTarget(self, action: Selector("tapDidNavi"), forControlEvents: .TouchUpInside)

    return cell
    }else{
    cell.title.text = tripspot[indexPath.row].title
    cell.location.text = tripspot[indexPath.row].location
    cell.naviButton.tag = indexPath.row
    cell.naviButton.addTarget(self, action: Selector("tapDidNavi"), forControlEvents: .TouchUpInside)
    print(cell.naviButton.tag.description)
    return cell
    }


 }

@IBAction func tapDidNavi(sender: UIButton){



}

谢谢你的建议!

您可以使用 MKMapItem.openMapsWithItems:launchOptions:在 map 应用中开始精细导航。

来自文档:

If you specify the MKLaunchOptionsDirectionsModeKey option in the launchOptions dictionary, the mapItems array must have no more than two items in it. If the array contains one item, the Maps app generates directions from the user’s current location to the location specified by the map item. If the array contains two items, the Maps app generates directions from the location of the first item to the location of the second item in the array.

@IBAction func tapDidNavi(sender: UIButton){

    let location = self.tripspot[sender.tag]

    let placemark = MKPlacemark(
        coordinate: coordinate, 
        addressDictionary: nil
    )

    let mapItem = MKMapItem(placemark: placemark)
    mapItem.name = location.title

    let options = [
        MKLaunchOptionsDirectionsModeKey: MKLaunchOptionsDirectionsModeDriving
    ]

    MKMapItem.openMapsWithItems([mapItem], launchOptions: options)
}
