【问题描述】：
我正在制作一个应用程序，您可以在其中上传照片，然后它获取的是 downloadURL 并将其保存在数据库中，但在将链接保存到数据库之前我收到错误。
*** 由于未捕获的异常“FIRInvalidArgumentException”而终止应用程序，原因：“不支持的类型：NSURL（在字段链接中找到）”
。 . .
libc++abi.dylib：以 NSException (lldb) 类型的未捕获异常终止
线程 1：信号 SIGABRT
我似乎无法理解为什么。
谢谢

【问题讨论】：
-
你能给出整个错误信息吗？它应该以“终止于”（带有大写“t”）开始，直到你给出的那个？即使您已经回答了您的问题，您给出的错误信息也缺少重要且有意义的部分。
-
是的，你写的。我现在去更新一下
-
你看，这条消息是说键 Link 的值是一个 NSURL 值，它不应该。通过阅读文档很容易阅读/理解并快速修复
