enter image description here我正在制作约会应用程序。 因此用户需要更新他们的个人资料中的图像。 在个人资料部分， 有小 3 个 ImageView 。 如果他们想将图像添加到每个 ImageView 中， 他们应该通过 UIimagepicker 更新每个 ImageView 。 但我知道我只能使用 UIImagepikerControllerDelegate 协议(protocol)中的一个函数。
我该怎么做？
下面是我失败的代码
导入UIKit
类RegisterPicture:UIViewController、UIImagePickerControllerDelegate、UINavigationControllerDelegate {
@IBAction func pick1(sender: AnyObject) {
let picker1 = UIImagePickerController()
picker1.sourceType = UIImagePickerControllerSourceType.SavedPhotosAlbum
picker1.allowsEditing = true
picker1.delegate = self
self.presentViewController(picker1, animated: false, completion: nil)
}
@IBAction func pick2(sender: AnyObject) {
let picker2 = UIImagePickerController()
picker2.sourceType = UIImagePickerControllerSourceType.SavedPhotosAlbum
picker2.allowsEditing = true
picker2.delegate = self
self.presentViewController(picker2, animated: false, completion: nil)
}
@IBAction func pick3(sender: AnyObject) {
let picker = UIImagePickerController()
picker.sourceType = UIImagePickerControllerSourceType.SavedPhotosAlbum
picker.allowsEditing = true
picker.delegate = self
self.presentViewController(picker, animated: false, completion: nil)
}
@IBOutlet var picture1: UIImageView!
@IBOutlet var picture2: UIImageView!
@IBOutlet var picture3: UIImageView!
func imagePickerController(picker1: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
picker1.dismissViewControllerAnimated(false, completion : nil)
}
func imagePickerController(picker2: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
picker2.dismissViewControllerAnimated(false, completion : nil)
self.picture2.image = info[UIImagePickerControllerOriginalImage] as? UIImage
}
func imagePickerController(picker3: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
picker3.dismissViewControllerAnimated(false, completion : nil)
self.picture3.image = info[UIImagePickerControllerOriginalImage] as? UIImage
}
func imagePickerControllerDidCancel(picker: UIImagePickerController) {
picker.dismissViewControllerAnimated(false, completion:nil)
}
func imagePickerControllerDidCancel(picker2: UIImagePickerController) {
picker2.dismissViewControllerAnimated(false, completion:nil)
}
func imagePickerControllerDidCancel(picker3: UIImagePickerController) {
picker3.dismissViewControllerAnimated(false, completion:nil)
}
最佳答案
不确定我是否理解您的需要，但我建议这些 UIImageView 可以位于 Collection View 中。
通过这样做，图像选择器的唯一委托(delegate)将是保存图像 Collection View 的 View Controller ，您只需使用所选图像更新所选单元格
关于ios - 如何添加多个 ImageView 并且每个 ImageView 都可以做图像选择器？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/37205196/
