Dissmissed UIViewController didreceivememorywarning - swift

Question

У меня есть пользовательский UIImagePickerController, который все еще, после того, как его отклонили, а переменная, установленная на nil, получает предупреждения о памяти, и это приводит к сбою моего приложения из-за этого.

Вот мой UIImagePickerController

import UIKit 
import MobileCoreServices 

class Picker: UIImagePickerController, UIImagePickerControllerDelegate, UINavigationControllerDelegate { 

var myView = PickerView(frame: UIScreen.mainScreen().bounds) 
var takenImages = [UIImage]() 
var takenImagesThumbs = [UIImage]() 
override init() { 
    super.init() 
    myView.picker = self 
    self.delegate = self 
    self.sourceType = UIImagePickerControllerSourceType.Camera 
    self.mediaTypes = [kUTTypeImage] 
    self.showsCameraControls = false 
    self.cameraOverlayView = myView 
    self.cameraCaptureMode = UIImagePickerControllerCameraCaptureMode.Photo 
    self.setFullscreen() 
    myView.viewing() 
} 
override init(nibName nibNameOrNil: String?, bundle nibBundleOrNil: NSBundle?) { 
    super.init(nibName: nibNameOrNil, bundle: nibBundleOrNil) 
} 
required init(coder aDecoder: NSCoder) { 
    super.init(coder: aDecoder) 
} 
func setFullscreen(){ 
    let screenSize = UIScreen.mainScreen().bounds.size 
    let scale = screenSize.height/screenSize.width*3/4 
    let translate = CGAffineTransformMakeTranslation(0,(screenSize.height - screenSize.width*4/3)*0.5); 
    let fullScreen = CGAffineTransformMakeScale(scale, scale); 
    self.cameraViewTransform = CGAffineTransformConcat(fullScreen, translate) 
} 
var endFunc:((images:[UIImage], thumbs:[UIImage]) -> Void)! 
var ViewController:UIViewController! 
func show(vc:UIViewController, complete: ((images:[UIImage], thumbs:[UIImage]) -> Void)) { 
    vc.presentViewController(self, animated: true, completion: nil) 
    endFunc = complete 
    ViewController = vc 
} 
var closeQueue = dispatch_queue_create("areyouareyou", nil) 
func close() { 
    let priority = DISPATCH_QUEUE_PRIORITY_DEFAULT 
    dispatch_async(dispatch_get_global_queue(priority, 0)) { 
     dispatch_async(self.closeQueue) { 
      self.endFunc(images: self.takenImages, thumbs: self.takenImagesThumbs) 
      self.takenImagesThumbs = [UIImage]() 
      self.takenImages = [UIImage]() 
      self.myView.update(self.takenImages.count) 
     } 
    } 
    self.removeFromParentViewController() 
    self.dismissViewControllerAnimated(true, completion: nil) 


} 
var resizequeue = dispatch_queue_create("hangingthree", nil) 
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) { 
    myView.takeButton.enabled = true 
    let nfo = info as NSDictionary 
    var image:UIImage = nfo.valueForKey(UIImagePickerControllerOriginalImage) as UIImage 
    takenImages.append(image) 
    self.myView.update(self.takenImages.count) 
    let priority = DISPATCH_QUEUE_PRIORITY_DEFAULT 
    dispatch_async(dispatch_get_global_queue(priority, 0)) { 
     dispatch_async(self.resizequeue) { 
      var theimg = Common.resizeImage(image, scaledToSize: CGSizeMake(UIScreen.mainScreen().bounds.width/3, UIScreen.mainScreen().bounds.width/3)) 
      self.takenImagesThumbs.append(theimg) 
     } 
    } 
} 
override func didReceiveMemoryWarning() { 
    super.didReceiveMemoryWarning() 
    println(self.takenImages.count) 
} 
} 

и вот мой OverlayView

import UIKit 

class PickerView: UIView { 
var picker:Picker! 

var takeButton = UIButton()

func viewing() {

    imageCount.textAlignment = NSTextAlignment.Center

} 
override func drawRect(rect: CGRect) {

    var colors = Colors() 
    CGContextSetLineWidth(context, 2)

    var point = CGPointMake((self.bounds.width/2), self.bounds.height - 30) 
    var start = CGFloat(Common.radians(0)) 
    var end = CGFloat(Common.radians(360)) 

    var moon = UIBezierPath() 
    moon.addArcWithCenter(point, radius: 45, startAngle: end, endAngle: start, clockwise: true) 
    moon.stroke() 
    moon.fill() 

    var left = UIBezierPath() 
    left.moveToPoint(CGPointMake(0, point.y)) 
    left.addLineToPoint(CGPointMake(point.x - 45, point.y)) 
    left.stroke() 

    var right = UIBezierPath() 
    right.moveToPoint(CGPointMake(self.bounds.width, point.y)) 
    right.addLineToPoint(CGPointMake(point.x + 45, point.y)) 
    right.stroke() 

    btnCloseing() 
    btnTakeing()

} 
func btnCloseing() {

Любой знает проблему, или как это исправить?

Answer 1

Ваша проблема в том, что вы являетесь подклассом UIImagePickerController, что запрещено. Читайте Apple documentation:

ВАЖНОЕ

UIImagePickerController класс поддерживает портретный режим только. Этот класс предназначен для использования как-is и не поддерживает подклассы. Иерархия представления для этого класса является частной и не может быть изменена с одним исключением. Вы можете назначить собственное представление свойства cameraOverlayView и использовать это представление для предоставления дополнительной информации или управления взаимодействием между интерфейсом камеры и вашим кодом.
