我正在选择一个按钮的项目并在具有表视图的另一个视图控制器上弹出地址簿。问题是应用程序在手机上崩溃但在模拟器中没有崩溃。
第一个视图的代码在这里：
import UIKit
import MobileCoreServices
import Parse
class MainPageViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
@IBOutlet weak var btnAddress : UIButton!
override func viewDidLoad() {
super.viewDidLoad()
self.title = "Overview"
btnAddress.layer.cornerRadius = 5;
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
@IBAction func getAddressBook (sender : AnyObject){
self.performSegueWithIdentifier("AddressController", sender: self);
}
@IBAction func MyVideosClicked(sender: AnyObject) {
}
@IBAction func RecordButtonClicked(sender: AnyObject) {
if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.Camera) {
println("captureVideoPressed and camera available.")
var imagePicker = UIImagePickerController()
imagePicker.delegate = self
imagePicker.sourceType = .Camera;
imagePicker.mediaTypes = [kUTTypeMovie!]
imagePicker.allowsEditing = false
imagePicker.showsCameraControls = true
self.presentViewController(imagePicker, animated: true, completion: nil)
}
else {
println("Camera not available.")
}
}
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject: AnyObject]) {
let tempImage = info[UIImagePickerControllerMediaURL] as! NSURL!
let pathString = tempImage.relativePath
self.dismissViewControllerAnimated(true, completion: {
})
// save video to library
UISaveVideoAtPathToSavedPhotosAlbum(pathString, self, nil, nil)
var videoData = NSData(contentsOfFile:pathString!)
var paths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0] as! String
var dataPath = paths.stringByAppendingPathComponent("myalbum")
if (!(NSFileManager.defaultManager().fileExistsAtPath(dataPath)))
{
NSFileManager.defaultManager().createDirectoryAtPath(dataPath, withIntermediateDirectories: false, attributes: nil, error: nil)
}
var dateFormat = NSDateFormatter()
dateFormat.dateFormat = "dd-MM-yyyy-HH:mm:SS"
var now = NSDate()
var dateStr = dateFormat.stringFromDate(now)
// var getImagePath = paths.stringByAppendingPathComponent("/SavedFile.mov")
var videopath = dataPath + "/" + dateStr + ".mov"
var success = videoData?.writeToFile(videopath, atomically: false)
if((success) != nil)
{
println(videopath)
performSegueWithIdentifier("VideoList", sender: nil)
}
else
{
println("Not Saved")
}
}
@IBAction func leftSideButtonTapped(sender: AnyObject) {
var appDelegate:AppDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
appDelegate.drawerContainer!.toggleDrawerSide(MMDrawerSide.Left, animated: true, completion: nil)
}
}

我真的不明白为什么应用程序崩溃了。有什么想法吗？
