Here is a code for popup galary in IPad
import UIKit
class ViewController: UIViewController,UIImagePickerControllerDelegate,UINavigationControllerDelegate,UIPopoverPresentationControllerDelegate {
var imagePicker = UIImagePickerController()
var popController:UIPopoverPresentationController!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
#IBAction func btn_action(sender: UIButton) {
if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.SavedPhotosAlbum) {
self.imagePicker.delegate = self
self.imagePicker.sourceType = UIImagePickerControllerSourceType.SavedPhotosAlbum
self.imagePicker.allowsEditing = true
imagePicker.modalPresentationStyle = UIModalPresentationStyle.Popover
self.presentViewController(self.imagePicker, animated: true, completion: nil)
popController = imagePicker.popoverPresentationController!
popController.permittedArrowDirections = UIPopoverArrowDirection.Up
popController.delegate = self
popController.sourceView = self.view
let contentSize : CGSize = CGSizeMake(500,400)
self.imagePicker.preferredContentSize = contentSize
popController.backgroundColor=UIColor.redColor()
popController.sourceRect = CGRectMake(sender.frame.origin.x + sender.bounds.width/2-5, sender.frame.origin.y+sender.bounds.size.height/2, 10, 10)
}
}
internal override func supportedInterfaceOrientations() -> UIInterfaceOrientationMask
{
return UIInterfaceOrientationMask.Landscape
}
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject])
{
}
func imagePickerControllerDidCancel(picker: UIImagePickerController)
{
imagePicker.dismissViewControllerAnimated(true, completion: nil)
}
}
