Hope someone can help? I have two queries on a single view. The first populates a table that works as intended. The second query I want to populate a UIPickerView and this is causing me grief :(
I can see the results in the println statement If someone can help it would be greatly appreciated
Here is the code class ProfileVC: UIViewController {
var pickerString = NSArray() as AnyObject as [String]
var industryValue = [getIndustries]()
@IBOutlet weak var StoredIndustries: UITableView!
@IBOutlet weak var countryControl: UIPickerView!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
var query = PFQuery(className:"Industries")
query.findObjectsInBackgroundWithBlock {
(objects: [AnyObject]!, error: NSError!) -> Void in
if error == nil {
// query successful - display number of rows found
println("Successfully retrieved \(objects.count) industries")
// print sentences found
for object in objects {
let retrievedIndustries = object["Sector"] as NSString
self.industryValue += [getIndustries(parseIndustry:"\(retrievedIndustries)")]
println("\(retrievedIndustries) ")
}
} else {
// Log details of the failure
println("Error: \(error) \(error.userInfo!)")
}
self.StoredIndustries.reloadData()
}
var query2 = PFQuery(className: "CountryLanguage")
query2.findObjectsInBackgroundWithBlock {
(objects: [AnyObject]!, error: NSError!) -> Void in
if error == nil {
println("Successfully retrieved \(objects.count) Countries")
var counter: Int = 0
for object in objects {
var storeString = ""
let retrievedLanguages = object["Language"] as NSString
let retrievedCode = object["Ccode"] as NSString
println("\(retrievedLanguages)" + " - " + "\(retrievedCode)")
storeString = ("\(retrievedLanguages)" + " - " + "\(retrievedCode)")
self.pickerString.insert(storeString, atIndex:counter)
counter = counter + 1
}
//self.countryControl.reloadAllComponents()
}
}
}
Thanks in advance
You should uncomment self.countryControl.reloadAllComponents()
inside your findObjectsInBackgroundWithBlock
, so that your `UIPickerView can refresh.
Also you need to make your UIViewControl extends the UIViewController,UIPickerViewDataSource
and UIPickerViewDelegate
. Do the following:
class ViewController: UIViewController,UIPickerViewDataSource,UIPickerViewDelegate {
}
Then in the viewDidLoad()
method, set the delegate and datasource of your UIPickerView
override func viewDidLoad() {
super.viewDidLoad()
countryControl.delgete = self
countryControl.dataSource = self
......}
Also you should implement the following delegate methods for UIPickerView
:
func numberOfComponentsInPickerView(pickerView: UIPickerView) -> Int {
return 1
}
func pickerView(pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
return self.pickerString.count
}
func pickerView(pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String! {
return self.pickerString[row]
}
