Question

尝试使用以下功能时

func imagePickerController(picker: UIImagePickerController,didFinishPickingImage image: UIImage, editingInfo: [String: AnyObject]?) {
    let selectedImage:UIImage = (editingInfo[UIImagePickerControllerOriginalImage]) as! UIImage
    displayImage.image = selectedImage
    self.dismissViewControllerAnimated(true, completion: nil)
}

得到错误：＆＃34;不能下标类型＆＃39; [String：AnyObject]的值？索引类型为＆＃39; String＆＃39;

在第二行，我写了一个let selected Image

这对Xcode 6.3＆amp; 6.4但现在使用新的Xcode 7 beta 4不起作用并抛出错误。

帮助！

Answer 1

在将图像设置为imageView之前尝试关闭控制器将您的方法替换为：

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) {
 self.dismissViewControllerAnimated(true, completion: nil)
let selectedImage:UIImage = (editingInfo[UIImagePickerControllerOriginalImage]) as! UIImage
displayImage.image = selectedImage

}

Answer 2

我在imagePickerController的文档中找到了答案。我必须使用的方法是didFinishPickingMediaWithInfo，而不是如下：

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

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

尝试使用imagePickerController下面的代理函数时出错：
