通過iOS應用閱讀郵箱或用戶節點

Question

爲什麼這個代碼給出錯誤讀取收件箱

FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc] 
           initWithGraphPath:@"/me/inbox" 
           parameters:@{@"fields":@"inbox"} 
           HTTPMethod:@"GET"]; 

錯誤我得到的控制檯：

{ 
    code = 100; 
    message = "You can only access the \"inbox\" connection for the current user."; 
} 

好像如果我使用其中此代碼取回收件箱它取我的收件箱：

FBSDKGraphRequest *request =[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" 
                  parameters:@{ @"fields" : @"inbox"}]; 

Answer 1

想通不能通過字段PARAM

FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc] 
           initWithGraphPath:@"/me/inbox?limit=50" 
           parameters:nil  
           HTTPMethod:@"GET"];
