Ios 在Swift中自定义Twitter解析登录

我想创建自定义视图控制器twitter解析登录。我不想使用Parse提供的默认“loginViewController”字段。我还想从twitter中提取用户的屏幕名称和个人资料图片，并将其保存在Parse中。这是我的密码

问题是——这段代码在某种程度上不起作用吗？如果是的话，你有什么问题？在解析教程中，你使用默认的twitter登录按钮。该按钮使用PFloginViewController通过解析自动创建twitter登录。我不想使用PFloginViewController。我设计了自己的控制器及其twitter按钮。There是在线示例，显示自定义解析登录而不使用PFloginViewController，但没有在线示例l显示使用默认解析twitter按钮的自定义twitter登录。如果有人不理解，请观看这两个教程。1..2问答，这样做的方法是自己回答自己的问题，即发布一个问题“我如何做X”，然后在下面发布一个答案，说明如何做。请参阅常见问题解答。是的，我回答了，但请不要急于对问题进行评分，因为构建堆栈溢出配置文件需要时间。
