我正致力于从 Objective-C 教程转换此委托(delegate)协议(protocol)函数,但在尝试通过使用下标返回基于键的值来访问字典中的值时遇到错误。我不太确定这里的错误是什么意思。任何帮助将不胜感激!

// Sent to the delegate to determine whether the sign up request should be submitted to the server
func signUpViewController(signUpController: PFSignUpViewController!, shouldBeginSignUp info: [NSObject : AnyObject]!) -> Bool {
var informationComplete: Bool = true

// Loop through all of the submitted data
for key in info {
var field: String = info[key] // Error occurs at this line on info
if field.isEmpty {
informationComplete = false
break
}
}

// Display an alert if a field was not completed
if !informationComplete {
let alertView: UIAlertView = UIAlertView(title: "Missing Information", message: "Please make sure all information is filled out!", delegate: nil, cancelButtonTitle: "ok")
}

return informationComplete
}

最佳答案

您没有发布声明。但您可能可以通过以下方式解决它:

for (key, field) in info {
if field.isEmpty {
informationComplete = false
break
}
}
