我创建了一个单独的类,其子类是tableViewController,我在MapViewController中继承它,但是地址未在表视图中加载。 TableView在模拟器上是空白的。请告诉我一些方法,它可以通过tableView
传递值(通过谷歌API的不同地方的名称)override func viewDidLoad()
{
super.viewDidLoad()
self.searchResults = Array()
self.tableView.registerClass(UITableViewCell.self, forCellReuseIdentifier: "cellIdentifier")
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
// MARK: - Table view data source
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// #warning Incomplete implementation, return the number of rows
return self.searchResults.count
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("cellIdentifier", forIndexPath: indexPath)
cell.textLabel?.text = self.searchResults[indexPath.row]
return cell
}
override func tableView(tableView: UITableView,
didSelectRowAtIndexPath indexPath: NSIndexPath){
// 1
self.dismissViewControllerAnimated(true, completion: nil)
// 2
let correctedAddress:String! = self.searchResults[indexPath.row].stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.symbolCharacterSet())
let url = NSURL(string: "https://maps.googleapis.com/maps/api/geocode/json?address=\(correctedAddress)&sensor=false")
let task = NSURLSession.sharedSession().dataTaskWithURL(url!) { (data, response, error) -> Void in
// 3
do {
if data != nil{
let dic = try NSJSONSerialization.JSONObjectWithData(data!, options: NSJSONReadingOptions.MutableLeaves) as! NSDictionary
let lat = dic["results"]?.valueForKey("geometry")?.valueForKey("location")?.valueForKey("lat")?.objectAtIndex(0) as! Double
let lon = dic["results"]?.valueForKey("geometry")?.valueForKey("location")?.valueForKey("lng")?.objectAtIndex(0) as! Double
// 4
self.delegate.locateWithLongitude(lon, andLatitude: lat, andTitle: self.searchResults[indexPath.row] )
}
}
catch
{
print("Error")
}
}
// 5
task.resume()
}
func reloadDataWithArray(array:[String])
{
self.searchResults = array
self.tableView.reloadData()
}
}
