下面显示的代码就是我已经尝试过的.我希望实现的是从设备中获取所有照片.目前只有少数被提取.如何修改代码以便从设备加载所有图像？

let fetchOptions = PHFetchOptions()

let collection:PHFetchResult = PHAssetCollection.fetchAssetCollectionsWithType(.Moment, subtype: .Any, options: fetchOptions)

if let first_Obj:AnyObject = collection.firstObject
{
    self.assetCollection = first_Obj as! PHAssetCollection
}

我想在询问触摸ID时模糊背景，并且一旦授权成功，就需要可见的视图控制器，但这并没有发生。即使授权成功，视图控制器仍然是模糊的。解决这个？

import UIKit
import LocalAuthentication
class TabBarViewController: UITabBarController {

@IBOutlet weak var noteTabBar: UITabBar!

override func viewDidLoad() {
super.viewDidLoad()
    self.authenticateUser()
    self.tabBar.hidden = false
    self.view.addGestureRecognizer(self.revealViewController().panGestureRecognizer())

    let userDefaults = NSUserDefaults.standardUserDefaults()
    userDefaults.setObject(false, forKey: "sendModeToggle")
    userDefaults.setObject("Avenir-Medium", forKey: "font")
     userDefaults.setObject(13, forKey:"fontSize")
            // Do any additional setup after loading the view.
}
override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}


/*
// MARK: - Navigation

// In a storyboard-based application, you will often want to do a little preparation …

是否有可能做到这一点 ？？我有一个出现在viewcontroller中的UIAlertController.我希望实现的是当警报出现时模糊/覆盖背景,一旦警报消失,背景应该是可见的

import UIKit import LocalAuthentication类TabBarViewController:UITabBarController {

@IBOutlet weak var noteTabBar: UITabBar!

override func viewDidLoad() {
super.viewDidLoad()
    self.authenticateUser()
    self.tabBar.hidden = false
    self.view.addGestureRecognizer(self.revealViewController().panGestureRecognizer())

    let userDefaults = NSUserDefaults.standardUserDefaults()
    userDefaults.setObject(false, forKey: "sendModeToggle")
    userDefaults.setObject("Avenir-Medium", forKey: "font")
     userDefaults.setObject(13, forKey:"fontSize")
            // Do any additional setup after loading the view.
}
override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}
