我正在尝试追加从解析数据库中检索到的图像，但是没有任何内容添加到UIImage数组中。如何附加检索到的图像？

 var arrayOfFriends: [UIImage] = []

 func getFriendPic(){

    var imagequery = PFQuery(className: "_User")
    imagequery.findObjectsInBackgroundWithBlock {( objects: [AnyObject]?, error: NSError?) -> Void in
        for object in objects!{
            let userPic = object["ProPic"] as! PFFile
            userPic.getDataInBackgroundWithBlock({ (imageData: NSData?, error: NSError?) -> Void in
                if(error == nil){
                    let image = UIImage(data: imageData!)
                    //breakpoint placed on line below, but app crashes with array out of bounds.
                    self.arrayOfFriends.append(image!)
                    print(self.arrayOfFriends)
                }
                dispatch_async(dispatch_get_main_queue()) {
                    self.collectionView.reloadData()
                }
            })

        }
    }
}

代码不是问题，它是Xcode，这是任何遇到同样问题的人的解决方案。 The resource could not be loaded because the App Transport Security policy requires the use of a secure connection

为什么没有将图像添加到阵列中？
