我有一个带有 2 个 UIImageViews 和 2 个按钮的 View ，以便使用 UIImagePickerViewController 选择 2 个不同的图片。它实际上工作完美，但我想缩放图像并最终在 UIImageViews 中显示图像的选定部分。
允许编辑与缩放一起正常工作，它显然“允许编辑”图片，但最终所选部分未显示在 UIImageViews 中。
代码在这里。怎么了？
import UIKit
var fotoUnoEscogida = UIImage()
var fotoDosEscogida = UIImage()
class viewControllerDso : UIViewController, UIImagePickerControllerDelegate ,UINavigationControllerDelegate, UITextViewDelegate{
//Images
@IBOutlet weak var imageView1: UIImageView!
@IBOutlet weak var imageView2: UIImageView!
//TextViews
@IBOutlet weak var textViewExteriorUno: UITextView!
@IBOutlet weak var textViewExteriorDos: UITextView!
@IBOutlet weak var textViewInteriorUno: UITextView!
@IBOutlet weak var textViewInteriorDos: UITextView!
var imagePicker = UIImagePickerController()
var imagePicked = 0
override func viewDidLoad() {
super.viewDidLoad()
}
@IBAction func chooseImage(sender: UIButton) {
if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.SavedPhotosAlbum){
print("chooseImage Button capture ")
imagePicked = sender.tag
imagePicker.delegate = self
imagePicker.sourceType = .SavedPhotosAlbum
imagePicker.allowsEditing = true
self.presentViewController(imagePicker, animated: true, completion: nil)
}
}
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage
if imagePicked == 1 {
imageView1.contentMode = UIViewContentMode.ScaleAspectFill
imageView1.image = pickedImage
imageView1.layer.masksToBounds = true
imageView1.layer.borderWidth = 6
imageView1.layer.cornerRadius = imageView1.layer.frame.height/6
imageView1.layer.borderColor = UIColor.purpleColor().colorWithAlphaComponent(0.2).CGColor
} else if imagePicked == 2 {
imageView2.contentMode = UIViewContentMode.ScaleAspectFill
imageView2.image = pickedImage
imageView2.layer.masksToBounds = true
imageView2.layer.borderWidth = 6
imageView2.layer.cornerRadius = imageView2.layer.frame.height/6
imageView2.layer.borderColor = UIColor.purpleColor().colorWithAlphaComponent(0.2).CGColor
}
dismissViewControllerAnimated(true, completion: nil)
}
}
最佳答案
在 didFinishPickingMediaWithInfo 中
而不是
let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage
使用
let pickedImage = info[UIImagePickerControllerEditedImage] as? UIImage
关于ios - 允许编辑 UIImagePickerViewController 无法选择 2 个不同的图像，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/34509936/
