Question

大家好...在我的应用程序中，我已经包含了一个包含当前PFUser的所有数据的视图。一切都是在没有故事板的情况下直接从ios7上的代码完成...显示没有问题，但是当我执行注销然后再次使用与前一个不同的用户登录时，我没有更新信息。视图继续将用户的数据保存到我之后来的那个数据。

我的错误在哪里？

感谢所有Rory

我想我已经解决了！ ......问题在于：

[self FFCustomViewGraph]已插入viewDidLoad ...

我通过在viewDidLoad中移动它来解决它

 - (void) viewDidAppear: (BOOL) animated

现在，当我与其他用户登录时，我们会立即检索数据......

你认为这是对的还是只是运气？

注销后，当前PFUser不会在ViewController上重新加载数据
