这是在 IPad 中弹出 galary 的代码

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)
    }
}

extension UIImagePickerController
{
    public override func supportedInterfaceOrientations() -> UIInterfaceOrientationMask
    {
        return UIInterfaceOrientationMask.Landscape
    }
}
