一切正常，但我添加了一些代码来将图像保存到磁盘，一旦拍摄，它似乎不起作用，也没有给我一个错误，有什么想法吗？
func importPicture(action: UIAlertAction! = nil) {
let picker = UIImagePickerController()
picker.allowsEditing = true
picker.sourceType = .Camera
picker.delegate = self
presentViewController(picker, animated: true, completion: nil)
}
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
let _ = info[UIImagePickerControllerMediaType] as! NSString
var newImage: UIImage
if let possibleImage = info["UIImagePickerControllerEditedImage"] as? UIImage {
newImage = possibleImage
} else if let possibleImage = info["UIImagePickerControllerOriginalImage"] as? UIImage {
newImage = possibleImage
} else {
return
}
let imageName = NSUUID().UUIDString
let imagePath = getDocumentsDirectory().stringByAppendingPathComponent(imageName)
if let jpegData = UIImageJPEGRepresentation(newImage, 80) {
jpegData.writeToFile(imagePath, atomically: true)
}
dismissViewControllerAnimated(true, completion: nil)
images.insert(newImage, atIndex: 0)
collectionView.reloadData()
if mcSession.connectedPeers.count > 0 {
let imageData = UIImagePNGRepresentation(newImage)
var error: NSError?
do {
try mcSession.sendData(imageData!, toPeers: mcSession.connectedPeers, withMode: .Reliable)
}
catch let error1 as NSError {
error = error1
}
if error != nil {
let ac = UIAlertController(title: "Send error", message: error!.localizedDescription, preferredStyle: .Alert)
ac.addAction(UIAlertAction(title: "OK", style: .Default, handler: nil))
presentViewController(ac, animated: true, completion: nil)
}
}
}
func getDocumentsDirectory() -> NSString {
let paths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)
let documentsDirectory = paths[0]
return documentsDirectory
}
最佳答案
UIImageWriteToSavedPhotosAlbum(newImage, nil, nil, nil)
改用这个，经过测试并且工作正常
