鍵入objectId來解析雲代碼

Question

我試圖將一些參數傳遞給我的解析雲代碼函數，並在Xcode中收到以下錯誤消息。 cannot convert value of type '[String : String?]' to type '[NSObject : AnyObject]' in coercion。它工作正常，直到我參考incomingUser.objectId。以下是我所傳遞的代碼：

let params = ["userType" : userType, "recipient" : self.incomingUser.objectId] 

PFCloud.callFunctionInBackground("pushNotification", withParameters: params as [NSObject : AnyObject]) { 
    (res: AnyObject?, error: NSError?) -> Void in 
     print(res) 
     print(error) 
} 

感謝您提供任何幫助。

Answer 1

嘗試使用params as [NSObject: AnyObject?]代替。

或者如果API要求[NSObject: AnyObject]，則必須首先打開objectId。

guard let objectId = self.incomingUser.objectId else { return } 

然後做

let params = ["userType" : userType, "recipient" : objectId] 

PFCloud.callFunctionInBackground("pushNotification", withParameters: params as [NSObject : AnyObject]) { 
(res: AnyObject?, error: NSError?) -> Void in 
    print(res) 
    print(error) 
}
