Is there a possibility for access to the array defined in Master View Controller from Detail View Controller? I have a Master-Detail Application in xCode. In Master View Controller an Array is defined. In Detail View Controller there are detail informations according to one entry from this array.

Is it possible to get access from Detail View Controller to the array and update them?

回答by Michael Dautermann
Is there any link whatsoever between your Master and Detail view?
你的主视图和细节视图之间有任何联系吗？
If so, then you can expose access to the array via making it a "@property" of the Master View Controller that you can access from the Detail view controller.
如果是这样，那么您可以通过使其成为@property主视图控制器的“ ”来公开对数组的访问，您可以从细节视图控制器访问它。
Here is a related question with answers that may help you out. I can't give you more specific answers than this because you haven't said how you've set up your Master <-> Detail View Controller implementation.
这是一个相关的问题，其答案可能对您有所帮助。我不能给你比这更具体的答案，因为你没有说你是如何设置你的主 <-> 细节视图控制器实现的。
