Populating Events in to Tableview (Swift) - swift

Question

I am trying to populate my daily events in to tableview. I have made the connections. (datasource, delegate and tableview) But events value is returning 0.
Sorry if this has been asked else where. I need a little help.
Here is my code.
import UIKit
import EventKit
import EventKitUI
class MainViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
var eventStore: EKEventStore?
var events = [EKEvent]()
var startDate = NSDate()
var endDate = NSDate()
var cellIdentifier = "cell"
#IBOutlet var tableView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
automaticallyAdjustsScrollViewInsets = false
self.tableView.dataSource = self
self.tableView.delegate = self
self.tableView.registerClass(UITableViewCell.self, forCellReuseIdentifier: cellIdentifier);
//self.tableView.reloadData()
self.eventStore = EKEventStore()
fetchEvents { (arr:[EKEvent]) in
print(arr)
self.events = arr
//reload table
}
self.tableView.reloadData()
}
func fetchEvents(completed: ([EKEvent]) -> ()) {
eventStore!.requestAccessToEntityType(EKEntityType.Event, completion: {
granted, error in
let startDt = NSDate(timeIntervalSinceNow: -24 * 60 * 60);
let predicate = self.eventStore!.predicateForEventsWithStartDate(startDt, endDate: NSDate(), calendars: nil)
let events = self.eventStore!.eventsMatchingPredicate(predicate)
completed(events)
})
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
#IBAction func onLoadListButtonClicked(sender: AnyObject)
{
self.performSegueWithIdentifier("LoadTheList", sender: nil)
}
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
//MARK: UITableViewDataSource
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
//TEST PRINT EVENT COUNT
print("event count (print) \(events.count)")
return events.count
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cellIdentifier = "cell"
let cell:UITableViewCell! = tableView.dequeueReusableCellWithIdentifier(cellIdentifier, forIndexPath: indexPath)
let events:EKEvent! = self.events[indexPath.row]
cell.textLabel!.text = events.title
cell.detailTextLabel!.text = events.startDate.description
print("event cell returned")
return cell
}
}

Issue is your start date is NSDate(timeIntervalSinceNow: 24 * 60 * 60) that is one day ahead and your end date is current date; in short, you are checking event starts tomorrow and ends today ;)
Just use following method to get events started yesterday and ends today. For further use just change the startDt to any previous date.
func fetchEvents(completed: (NSMutableArray) -> ()) {
eventStore!.requestAccessToEntityType(EKEntityType.Event, completion: {
granted, error in
let startDt = NSDate(timeIntervalSinceNow: -24 * 60 * 60);
let predicate = self.eventStore!.predicateForEventsWithStartDate(startDt, endDate: NSDate(), calendars: nil)
let events = NSMutableArray(array: self.eventStore!.eventsMatchingPredicate(predicate))
completed(events)
})
}
Edit
Call this as:
fetchEvents { (arr:NSMutableArray) in
print(arr)
//reload your table
}

As per your comment:
I think its a breakpoint issue but I did not put a breakpoint. It's so
strange. imgur.com/a/nQGo1 imgur.com/a/MUb4i – bourbon 2 mins ago
I had looked at your code, in that remove viewWillAppear method and add self.eventStore = EKEventStore() above the fetchEvents function call in viewDidLoad.
One more important point assign arr to self.events and then reload the table. I have just changed the return type of method use following:
Method:
func fetchEvents(completed: ([EKEvent]) -> ()) {
eventStore!.requestAccessToEntityType(EKEntityType.Event, completion: {
granted, error in
let startDt = NSDate(timeIntervalSinceNow: -24 * 60 * 60);
let predicate = self.eventStore!.predicateForEventsWithStartDate(startDt, endDate: NSDate(), calendars: nil)
let events = self.eventStore!.eventsMatchingPredicate(predicate)
completed(events)
})
}
Method call:
fetchEvents { (arr:[EKEvent]) in
print(arr)
self.events = arr
//reload table
}
