ios - 如何保存照片和文字

Question

我有一张图片和一段文字。如果用户点击安全按钮，我想保存它。

@IBOutlet weak var img1: UIImageView!
@IBOutlet weak var text1: UITextField!
@IBAction func saveButton(sender: AnyObject) {
    save()
}

我可以使用 func 快照保护 View 。但是如何保存文本、img 和快照？

我尝试了功能保存。我在 func 保存中出错:“使用未解析的标识符对象”“使用未解析的标识符 imageView”

func save() {
    var object = Object( text: textField.text!, image:
        imageView.image, image: image)
}

func snapshot() -> UIImage {
    UIGraphicsBeginImageContext(self.view.frame.size)
    self.view.drawViewHierarchyInRect(self.view.frame,
        afterScreenUpdates: true)
    let image : UIImage =
    UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()

    return image
}

Answer 1

方法如下:

import UIKit

class ViewController: UIViewController {

    @IBOutlet weak var newImage: UIImageView!
    @IBOutlet weak var img1: UIImageView!

    @IBAction func saveIt(sender: AnyObject) {
        //first make an UIImage from your view
        UIGraphicsBeginImageContext(self.view.bounds.size)
        self.view.layer.renderInContext(UIGraphicsGetCurrentContext())
        let sourceImage = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()

        //draw new Image
        //position the image
        UIGraphicsBeginImageContext(img1.frame.size)
        sourceImage.drawAtPoint(CGPointMake(0, 0))
        let croppedImage = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        //assign new Image
        newImage.image = croppedImage
    }
}

结果将是:
