Working on a questions and answer app similar to Quora.
The app compiles, I see data in the output, but the tableview is empty. the data isnt appending the array? (using Swift 2, Xcode 7.2)
import UIKit
class QuestionsTableViewController: UITableViewController {
let backendless = Backendless.sharedInstance()
var showAllQuestions = [String]()
//var showAllQuestions = [String:AnyObject] = [Question]() as [String:AnyObject]
var currentQuestion = [Question]()
override func viewDidLoad() {
super.viewDidLoad()
Types.tryblock({ () -> Void in
let startTime = NSDate()
let query = BackendlessDataQuery()
var allQuestions = self.backendless.persistenceService.of(Question.ofClass()).find(query)
print("Total Questions in the Backendless starage - \(allQuestions.totalObjects)")
let bc1 : BackendlessCollection = allQuestions as BackendlessCollection
for order : Question in bc1.data as! [Question] {
self.showAllQuestions.appendContentsOf(self.showAllQuestions)
self.tableView.reloadData()
}
var size = allQuestions.getCurrentPage().count
while size > 0 {
print("Loaded \(allQuestions) questions in the current page")
allQuestions = allQuestions.nextPage()
size = allQuestions.getCurrentPage().count
}
print("Total time (ms) - \(1000*NSDate().timeIntervalSinceDate(startTime))")
},
catchblock: { (exception) -> Void in
print("Server reported an error: \(exception as! Fault)")
}
)
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return showAllQuestions.count
}
override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("questionCell",
forIndexPath: indexPath) as! QuestionsTableViewCell
cell.userNameLabel.text = showAllQuestions[indexPath.row]
cell.questionLabel?.text = showAllQuestions[indexPath.row]
return cell
}
This outputs this:
Total Questions in the Backendless starage - 8
`Loaded <BackendlessCollection> -> type: BloQuery2.Question, offset: 0, pageSize: 100, totalObjects: 8, data: (
"<BloQuery2.Question: 0x7faab60091f0>",
"<BloQuery2.Question: 0x7faab3e1f280>",
"<BloQuery2.Question: 0x7faab600aae0>",
"<BloQuery2.Question: 0x7faab600bbf0>",
"<BloQuery2.Question: 0x7faab600cd80>",
"<BloQuery2.Question: 0x7faab600ddf0>",
"<BloQuery2.Question: 0x7faab600eeb0>",
"<BloQuery2.Question: 0x7faab600ffa0>"
), query: <BackendlessDataQuery> -> properties: (null), whereClause: (null), queryOptions: <QueryOptions> -> {
offset = 0;
pageSize = 100;
related = (
);
} questions in the current page
