Infinite scroll on tableView placed inside a UIViewController in Swift - ios

Question

I am very new to Swift and for the last few days I have been trying to figure out how I can implement infinite scroll in tableView which is placed inside a ViewController. All the examples I have found are based on TableViewController but my tableView is placed inside a ViewController.
Actually I am using the library MMDrawerLayout to get a left and right sliding menu so need to use a ViewController. Please some one guide me in the right direction. Any code or sample projects will be much appreciated.
Thanks.

First of all drag and drop tableview into your viewController in storyBoard after that create an Outlet for your tableview like this:
#IBOutlet weak var tableView: UITableView!
And add your tableArray:
var items: [String] = ["We", "Heart", "Swift"]
After that add UITableViewDataSource, UITableViewDelegate at your class declaration and it look like:
class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
//Your code
}
After that conform dataSource and deleget to self in your viewDidLoad method and add thi line in it:
self.tableView.registerClass(UITableViewCell.self, forCellReuseIdentifier: "cell")
After that your method will be:
override func viewDidLoad() {
super.viewDidLoad()
tableView.delegate = self
tableView.dataSource = self
self.tableView.registerClass(UITableViewCell.self, forCellReuseIdentifier: "cell")
}
After that add required method of UITableViewDataSource as shown below:
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return self.items.count
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
var cell:UITableViewCell = self.tableView.dequeueReusableCellWithIdentifier("cell") as! UITableViewCell
cell.textLabel?.text = self.items[indexPath.row]
return cell
}

To Add infinity indicator view in bottom of your UITableView then followed the following things.
Step 1 : Add following method in your current class.
func infinityScrollView() {
var bounds = UIScreen.mainScreen().bounds
var width = bounds.size.width
var height = bounds.size.height
var footerView = UIView(frame: CGRectMake(0, 0, width, 44))
footerView.backgroundColor=UIColor.greenColor()
var actInd: UIActivityIndicatorView = UIActivityIndicatorView()
actInd.center = CGPointMake(width/2 , 22)
actInd.color = UIColor.redColor()
footerView.addSubview(actInd)
YOUR_TABLEVIEW_OBJECT.tableFooterView = footerView;
}
Step 2 : Called the above method from viewDidLoad.
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
self.infinityScrollView()
}
Hope this help you.
