Ios 使用未解析标识符'；requestIPViewController'，对成员'的模糊引用；下标'；

它告诉我代码上有一些问题

那我该怎么解决呢

self.presentViewController[requestIPViewController, animated:YES, completion:nil];

}
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) {
    let image = info[UIImagePickerControllerOriginalImage] as UIImage

---

如果是在swift 2.3中，那么应该是这样的

self.presentViewController(imagePicker, animated: true, completion: nil)

self.present(imagePicker, animated: true, completion: nil)

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

    let mediaType = info[UIImagePickerControllerMediaType] as! NSString

    self.dismiss(animated: true, completion: nil)

    if mediaType.isEqual(to: kUTTypeImage as String) {
        let image = info[UIImagePickerControllerOriginalImage]
            as! UIImage
    }
}

而且你必须像这样打字

let image = info[UIImagePickerControllerOriginalImage]
            as! UIImage

斯威夫特3.0看起来是这样的

self.presentViewController(imagePicker, animated: true, completion: nil)

self.present(imagePicker, animated: true, completion: nil)

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

    let mediaType = info[UIImagePickerControllerMediaType] as! NSString

    self.dismiss(animated: true, completion: nil)

    if mediaType.isEqual(to: kUTTypeImage as String) {
        let image = info[UIImagePickerControllerOriginalImage]
            as! UIImage
    }
}

detegate方法看起来是这样的

self.presentViewController(imagePicker, animated: true, completion: nil)

self.present(imagePicker, animated: true, completion: nil)

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

    let mediaType = info[UIImagePickerControllerMediaType] as! NSString

    self.dismiss(animated: true, completion: nil)

    if mediaType.isEqual(to: kUTTypeImage as String) {
        let image = info[UIImagePickerControllerOriginalImage]
            as! UIImage
    }
}

希望有帮助。

您在哪里声明了requestIPViewController，信息是什么？请检查并告诉结果当它是Swift 3.0+时，它是相同的东西没有任何变化。你能拍一张它的屏幕截图吗？我想你还没有声明requestIPViewController，第一个错误就是因为这个，请检查
