The activity indicator starts, but does not stop when the hide function is called. I've tried putting the hide function in various places, and it still does not hide.
Hide activity indicator: Q0ViewController().hideActivityIndicator(self.view)
I'm using the swift utility function found here: https://github.com/erangaeb/dev-notes/blob/master/swift/ViewControllerUtils.swift
Start activity indicator
override func viewDidLoad() {
super.viewDidLoad()
Q0ViewController().showActivityIndicator(self.view)
self.locationManager.delegate = self //location manager start
self.locationManager.desiredAccuracy = kCLLocationAccuracyBest
self.locationManager.requestWhenInUseAuthorization()
self.locationManager.startUpdatingLocation()
}
Hide activity indicator after query:
func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!) {
CLGeocoder().reverseGeocodeLocation(manager.location, completionHandler: { (placemarks, error) -> Void in
if (error != nil) {
println("Error:" + error.localizedDescription)
//return
}
if placemarks.count > 0 {
let pm = placemarks[0] as CLPlacemark
self.displayLocationInfo(pm)
currentLoc = manager.location
currentLocGeoPoint = PFGeoPoint(location:currentLoc)
var query = PFQuery(className:"test10000")
query.whereKey("RestaurantLoc", nearGeoPoint:currentLocGeoPoint, withinMiles:100) //filter by miles
query.limit = 1000 //limit number of results
query.findObjectsInBackgroundWithBlock {
(objects: [AnyObject]!, error: NSError!) -> Void in
if objects != nil {
unfilteredRestaurantArray = objects
originalUnfilteredArray = objects
println(objects)
} else {
println("error: \(error)")
}
Q0ViewController().hideActivityIndicator(self.view) //HIDE
}
} else {
println("error: \(error)")
}
})
}
It is not an issue with the main queue as dispatch_after(DISPATCH_TIME_NOW, dispatch_get_main_queue(), { ()->() in
does not resolve the issue.
Similar to what Joshua suggested, just replaced:
Q0ViewController().showActivityIndicator(self.view)
and
Q0ViewController().hideActivityIndicator(self.view)
To:
self.showActivityIndicator(self.view)
and
self.hideActivityIndicator(self.view)
