Displaying Contact info on another ViewController with a segue - ios

Question

Im using contact framework to fetch user contact's name, number, email, and contact image, the data is being fetched. All I am able to display right now is only one of the keys in the table view, like either the name number or email, I wish to have the name be clicked and then segue to the other view controller where the rest of the properties show up. but I am having trouble displaying it on the other viewController. I have tried using the get contacts method in the prepareforsegue function, did not seem to work The code I am using to fetch contacts is
func getContacts() {
let store = CNContactStore()
if CNContactStore.authorizationStatusForEntityType(.Contacts) == .NotDetermined {
store.requestAccessForEntityType(.Contacts, completionHandler: { (authorized: Bool, error: NSError?) -> Void in
if authorized {
self.retrieveContactsWithStore(store)
}
})
} else if CNContactStore.authorizationStatusForEntityType(.Contacts) == .Authorized {
self.retrieveContactsWithStore(store)
}
tableView.reloadData()
}
func retrieveContactsWithStore(store: CNContactStore) {
do {
let groups = try store.groupsMatchingPredicate(nil)
// let predicate = CNContact.predicateForContactsInGroupWithIdentifier(groups[0].identifier)
let containerId = CNContactStore().defaultContainerIdentifier()
let predicate: NSPredicate = CNContact.predicateForContactsInContainerWithIdentifier(containerId)
let keysToFetch = [CNContactFormatter.descriptorForRequiredKeysForStyle(.FullName), CNContactEmailAddressesKey, CNContactPhoneNumbersKey,CNContactImageDataAvailableKey,CNContactThumbnailImageDataKey]
print(CNContactEmailAddressesKey.capitalizedString)
let contacts = try store.unifiedContactsMatchingPredicate(predicate, keysToFetch: keysToFetch)
self.objects = contacts
dispatch_async(dispatch_get_main_queue(), { () -> Void in
self.tableView.reloadData()
})
} catch {
print(error)
}
}
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if let identifier = segue.identifier {
if identifier == "DetailContact" {
}
}
}

As i said in my comments, create a new contact object in your other controller. For example: yourContactObject and then set some value to it in the prepare for segue as follows:
var selectedContact;// Your contact which you will set in the did select of the other controller
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if let identifier = segue.identifier {
if identifier == "DetailContact" {
let controller = segue.destinationViewController
controller.yourContactObject = selectedContact.
}
}
}
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
selectedContact = objects[indexPath.row]
}

Instead of trying to re-do the query in prepareForSegue, make a property on your other view controller, say var contact: CNContactStore! and then observe which row gets selected in the table view. So in didSelectRowAtIndexPath you can do the following...
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
let contactSelected = yourDataModel[indexPath.row] //now you know which contact was selected
self.performSegueWithIdentifier("DetailContact", sender: contactSelected)
/**you can pass the selected contact as the sender argument,
or set it as a class-level variable,
or use a delegate or notification, all would work */
}
And then in your prepareForSegue method, could do the following...
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if let identifier = segue.identifier {
if identifier == "DetailContact" {
let controller = segue.destinationViewController
controller.contact = sender as! CNContactStore
}
}
}
