如何将 Swift 2.0中的NSArray？
我已经创build了一个像这样的dispatch_block_t数组，
let actions: [dispatch_block_t] = [ {self.pickImages()}, {self.takePicture()}] 现在，我想把这个[dispatch_block_t]转换成NSArray，这样我就可以把它传递给一个函数。 我已经尝试将此投影到NSArray。
let actionsArray: NSArray = actions as NSArray
但是我得到一个错误。
[dispatch_block_t]不能转换为NSArray
更新：完整的代码，
import UIKit import Foundation import MobileCoreServices import MediaPlayer class AttachFilesViewController: UIViewController, UINavigationBarDelegate, UIImagePickerControllerDelegate, UINavigationControllerDelegate, MultiImagePickerControllerDelegate, MPMediaPickerControllerDelegate, UITableViewDataSource, UITableViewDelegate { var tableView: UITableView = UITableView() var imgPkr: MultiImagePickerController! //For picking image(s) var cameraPkr: UIImagePickerController = UIImagePickerController() //For taking a picture var menuView: btSimplePopUP! var rightBarButtonItem = UIBarButtonItem() override func viewDidLoad() { super.viewDidLoad() self.view.backgroundColor = UIColor.whiteColor() //Creating Right bar button item let buttonRight = UIButton(type: UIButtonType.Custom) buttonRight.frame = CGRectMake(0, 0, 30, 30) buttonRight.setImage(UIImage(named:"add.png"), forState: UIControlState.Normal) buttonRight.addTarget(self, action: "openMenu:", forControlEvents: UIControlEvents.TouchUpInside) rightBarButtonItem = UIBarButtonItem(customView: buttonRight) tableView.delegate = self tableView.dataSource = self self.view.addSubview(tableView) } func openMenu(sender: UIButton){ if(menuView == nil){ let imgs = [UIImage(named: "pickImage.png")!, UIImage(named: "takePicture.png")!, UIImage(named: "pickVideo.png")!, UIImage(named: "shootVideo.png")!, UIImage(named: "recordAudio.png")!, UIImage(named: "quit.png")!] as NSArray let titles = ["Images", "Capture", "Videos", "Shoot", "Record", "Cancel"] as NSArray let actions: [dispatch_block_t] = [ {self.pickImages()}, {self.takePicture()},] let actionsArray = NSArray(array: actions) menuView = btSimplePopUP(itemImage: imgs as [AnyObject], andTitles: titles as [AnyObject], andActionArray: actionsArray as [AnyObject], addToViewController: self) self.view.addSubview(menuView) menuView.show(BTPopUpAnimation.UPAnimateWithFade) }else{ if(!menuView.isDescendantOfView(self.view)){ self.view.addSubview(menuView) menuView.show(BTPopUpAnimation.UPAnimateWithFade) } } } //For picking image(s) from gallery func pickImages(){ videoPkr = nil globalStruct.groupType = true imgPkr = MultiImagePickerController() imgPkr.pickerDelegate = self self.navigationController!.presentViewController(imgPkr, animated: true) {} } //For taking a picture with camera func takePicture(){ imgPkr = nil videoPkr = nil if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.Camera){ self.cameraPkr = UIImagePickerController() self.cameraPkr.delegate = self //UIImagePicker delegate self.cameraPkr.allowsEditing = false self.cameraPkr.sourceType = .Camera self.cameraPkr.cameraCaptureMode = .Photo self.cameraPkr.modalPresentationStyle = .FullScreen self.navigationController!.presentViewController(self.cameraPkr, animated: true, completion: nil) }else{ SCLAlertView().showError("No Camera!!", subTitle: "Sorry.. Your device does not have a camera!", closeButtonTitle: "Okay") } }
}
任何帮助将不胜感激。
