iphone - QuickDialog 没有以正确的方式显示日期

Question

我正在使用 quickdialog 来使用动态表单。Web 服务使用快速对话框 JSON 构建表单。对于 QDateTimeInlineElement，他为我提供了这个 JSON。

    {"type":"QDateTimeInlineElement","title":"datum","placeholder":"vul in","bind":"textValue:datum","key":"datum","mode":"Date"},
   {"type":"QDateTimeInlineElement","title":"tijd","placeholder":"vul in","bind":"textValue:tijd","key":"tijd","mode":"Time"},
  {"type":"QDateTimeInlineElement","title":"datumtijd","placeholder":"vul in","bind":"textValue:datumtijd","key":"datumtijd","mode":"DateAndTime"},

在我的代码中，我使用以下代码将所有值放入字典中。

 NSMutableDictionary *script = [NSMutableDictionary new];
 [self.root fetchValueUsingBindingsIntoObject:script];

但是当我查看这本词典的输出时，我注意到以下 LOG

Date = "00:00:-34";
DateTime = "00:00:-34"; 
TIME = "00:00:-34";

有人可以帮我吗？亲切的问候 ！
