Question

Error : Cannot subscript a value of type '[String: AnyOject]?' with an index of type 'String'

我一直在尝试按照 this developers site 中的教程进行操作: 但我似乎无法使这段代码工作。

func imagePickerController(picker: UIImagePickerController, didFinishPickingImage image: UIImage, editingInfo: [String : AnyObject]?) {
    let selectedImage = editingInfo[SUIImagePickerControllerOriginalImage] as! UIImage
    // Set photoImageView to selected image
    photoImageView.image = selectedImage

Answer 1

Swift 1.2 中的方法更改 Apple 没有修改他们的文档

你把函数改成这个:

func imagePickerController(picker: UIImagePickerController, didFinishPickingImage image: UIImage!, editingInfo: [NSObject : AnyObject]!) {

}

它应该可以工作
