不触摸屏幕就无法看到 table 查看项目

Question

我的 tableView class 我已经从我的服务器获取了数据并且可以在 table View 中显示，但问题是当我完全获取来自服务器的数据在我按下屏幕之前从未显示在 table 视图中。当我按下屏幕时，我可以看到我的数据，但我想在获得数据后查看我的数据。这是我的class ..

import Foundation
import UIKit

class MovementRep : UIViewController , UITableViewDelegate, UITableViewDataSource{


var unitID : Int = 0;
var count : Int = 0;

var dateTime = [String]()
var speed = [Double]()
var event = [String]()
var location = [String]()

var len : Int = 0;

var deviation = [String]()


@IBOutlet weak var ActivityIndicator: UIActivityIndicatorView!


@IBOutlet weak var tableView: UITableView!


override func viewDidLoad() {
    super.viewDidLoad()
    print("Movement Report Called");
    print("unit ID = \(unitID)")

尝试替换此代码：

override func viewDidLoad() {
    super.viewDidLoad()
    print("Movement Report Called");
    print("unit ID = \(unitID)")

    var id : String = String(self.unitID);
    print("string id = \(id)")

    self.ActivityIndicator.startAnimating()
