ios - ios 9.3 UIImagePickerController 内存问题

Question

截屏

UIImagePickerController在 iOS 9.2 上运行良好，我的 iPhone 内存使用量为 19m。

从 iOS 9.3 开始，我注意到内存使用量增加到 300m 并且应用程序崩溃了。

我的代码：

import UIKit  
import MobileCoreServices 

class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate { 

    override func viewDidLoad() {  
        super.viewDidLoad()    
    }  

    override func didReceiveMemoryWarning() {  
        super.didReceiveMemoryWarning()    
    }  

    func pick(){  
        let imagePicker = UIImagePickerController()  
        imagePicker.delegate = self  
        imagePicker.sourceType = UIImagePickerControllerSourceType.PhotoLibrary  
        imagePicker.mediaTypes = [String(kUTTypeImage)]  
        imagePicker.allowsEditing = false  

        self.presentViewController(imagePicker, animated: true, completion: nil)  
    }  

    func imagePickerController(picker: UIImagePickerController, didFinishPickingImage image: UIImage, editingInfo: [String : AnyObject]?) {  

    }  

    @IBAction func touched(sender: AnyObject) {  
        pick()  
    }  
}
