Question

我收到此错误，

  

＆＃34;类型的价值＆＃39;任何？＆＃39;在编译时没有成员＆＃39; valueForKey＆＃39;＆＃34;，用于userName，fbID，email和fbLink。

func croppImage(originalImage:UIImage, toRect rect:CGRect) -> UIImage{

var imageRef:CGImageRef = CGImageCreateWithImageInRect(originalImage.CGImage, rect)
var croppedimage:UIImage = UIImage(CGImage:imageRef)
return croppedimage
}

Answer 1

您必须将Any投射到更有意义的内容，例如[String:Any]

   guard let fbData = result as? [String:Any] else { return }

   let fbid = fbData["id"]
   let email = fbData["email"]
