在我的iPhone应用程序中，如果输入的电话号码已经附加到应用程序中的当前用户，我正在尝试注册。
我可以验证我的文本字段条目是否与用户在应用程序中的电话号码相同，但以下函数始终会返回错误：
QBRequest.usersWithPhoneNumbers([self.mobileNumberTextField.text!], successBlock: { (response: QBResponse, page: QBGeneralResponsePage?, user: [QBUUser]?) in
print("user")
}, errorBlock: { (response: QBResponse) in
print("no user")
})
以下是错误输出：
