Ios 如何拍摄照片并将其传递给另一个viewcontroller

我想使用设备的照相机拍摄照片。我想使用segue将图像传递给另一个viewcontroller。图像只需在第二个viewcontroller中显示。但图像需要保存到设备的照片库。如何使用imagepicker实现此目的

我试用过的代码如下所示

 func takePhoto(sender : UIButton)
 {
    if (UIImagePickerController.isSourceTypeAvailable(.Camera))
    {
        if UIImagePickerController.availableCaptureModesForCameraDevice(.Rear) != nil {
            imagePicker.allowsEditing = false
            imagePicker.sourceType = .Camera
            imagePicker.cameraCaptureMode = .Photo
            presentViewController(imagePicker, animated: true, completion: {})
        } else {
            print("Rear camera doesn't exist Application cannot access the camera.")
        }
    } else {
        print("Camera inaccessable Application cannot access the camera.")
    }

 }

func imagePickerController(picker: UIImagePickerController, didFinishPickingImage image: UIImage, editingInfo: [String : AnyObject]?)
{
    TakenImage = image
    let selectorToCall = Selector("imageWasSavedSuccessfully:didFinishSavingWithError:context:")
    UIImageWriteToSavedPhotosAlbum(TakenImage!, self, selectorToCall, nil)

}

func imagePickerControllerDidCancel(picker: UIImagePickerController)
{
    print("User canceled image")
    dismissViewControllerAnimated(true, completion: {
        // Anything you want to happen when the user selects cancel
    })
}

func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath)
{
    if (indexPath.row == 0)
    {
    let controller = self.storyboard!.instantiateViewControllerWithIdentifier("NoteDetailViewController") as! NoteDetailViewController
        controller.takinPhoto = true
        if(noteAlreadyEntered == true)
        {
            if (note != "")
            {
                controller.content = note
            }
            controller.takenImage = TakenImage
            if (self.tags != "")
            {
                controller.tagsTextField.text = self.tags
            }
        }
        else
        {
            controller.takenImage = TakenImage
            if (self.tags != "")
            {
                controller.tagsTextField.text = self.tags
            }
        }

    self.navigationController!.pushViewController(controller, animated: true)
    }
}

TakenImage被传递到下一个viewcontroller。但是图像没有出现在那里。图像也没有保存到库中

用于传递的代码如下所示

 func takePhoto(sender : UIButton)
 {
    if (UIImagePickerController.isSourceTypeAvailable(.Camera))
    {
        if UIImagePickerController.availableCaptureModesForCameraDevice(.Rear) != nil {
            imagePicker.allowsEditing = false
            imagePicker.sourceType = .Camera
            imagePicker.cameraCaptureMode = .Photo
            presentViewController(imagePicker, animated: true, completion: {})
        } else {
            print("Rear camera doesn't exist Application cannot access the camera.")
        }
    } else {
        print("Camera inaccessable Application cannot access the camera.")
    }

 }

func imagePickerController(picker: UIImagePickerController, didFinishPickingImage image: UIImage, editingInfo: [String : AnyObject]?)
{
    TakenImage = image
    let selectorToCall = Selector("imageWasSavedSuccessfully:didFinishSavingWithError:context:")
    UIImageWriteToSavedPhotosAlbum(TakenImage!, self, selectorToCall, nil)

}

func imagePickerControllerDidCancel(picker: UIImagePickerController)
{
    print("User canceled image")
    dismissViewControllerAnimated(true, completion: {
        // Anything you want to happen when the user selects cancel
    })
}

func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath)
{
    if (indexPath.row == 0)
    {
    let controller = self.storyboard!.instantiateViewControllerWithIdentifier("NoteDetailViewController") as! NoteDetailViewController
        controller.takinPhoto = true
        if(noteAlreadyEntered == true)
        {
            if (note != "")
            {
                controller.content = note
            }
            controller.takenImage = TakenImage
            if (self.tags != "")
            {
                controller.tagsTextField.text = self.tags
            }
        }
        else
        {
            controller.takenImage = TakenImage
            if (self.tags != "")
            {
                controller.tagsTextField.text = self.tags
            }
        }

    self.navigationController!.pushViewController(controller, animated: true)
    }
}

如何解决此错误？

您需要首先确定图像是单击的还是从“多媒体资料”中选择的。如果单击，则将布尔值更改为“是”，并在其中使用承保代码。这将在gallery中保存您的图像：

func imagePickerController（picker:UIImagePickerController，didFinishPickingMediaWithInfo:[字符串：任意对象]） { picker.dismissViewControllerAnimated（true，完成：nil）

让imageData=UIImageJPEG表示（imageCLicked，0.6） 让compressedJPGImage=UIImage（数据：imageData！） AlasSetLibrary（）.writeImageToSavedPhotosAlbum（CompressedJjpgImage！.CGImage，方向：ALAssetOrientation（rawValue:CompressedJjpgImage！.imageOrientation.rawValue）！， completionBlock:{（路径：NSURL！，错误：NSError！）->中的Void 打印（“（路径）”//在这里您将获得您的路径 }) }

希望对你有用

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {

        let image = info[UIImagePickerControllerOriginalImage] as? UIImage 
        self.imagePickerController.dismissViewControllerAnimated(true, completion: nil)
}

使用prepareforsegue传递图像：

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
        if segue.identifier == "yoursegueidentifier" {

            let dvc = segue.destinationViewController as! yourViewController
            dvc.image = image
        }
    }

你在这方面需要什么帮助？这个问题太宽泛了。请尝试一些方法，并将您的问题更新为一个单一的、有重点的问题，您需要帮助。您可以用传递int的相同方式传递图像吗？
