从MainController发送消息到Delegate-Swift
[英]Sending a message from MainController to Delegate - Swift
问题描述
I'm sending an interactive local notification with one button. 
我正在通过一个按钮发送交互式本地通知。
The local notification text is taken from an array in MainViewController . 本地通知文本来自MainViewController中的数组。 Yet i have to set it's title in the AppDelegate ... 但是我必须在AppDelegate中设置它的标题...
Once this button is pressed - the app responds and sends me another local notification with different text and a different button title. 按下此按钮后-该应用程序会做出响应，并向我发送另一条带有不同文本和不同按钮标题的本地通知。
The issue is - the text for the button is placed in a second array in the MainViewController . 问题是-按钮的文本放置在MainViewController的second array中。 How would you guys handle such a thing? 你们将如何处理这样的事情？
Thank you! 谢谢！

If I were you, I would make this array a public variable in MainViewController . 如果我是你，我将在MainViewController将此数组MainViewController一个公共变量。 Also, I would have a reference to MainViewController in AppDelegate . 另外，我将在AppDelegate引用MainViewController 。 Then simply refer to MainViewController instance in AppDelegate and get that array. 然后只需引用AppDelegate MainViewController实例并获取该数组。
Alternatively, you can create a similar array variable in AppDelegate . 或者，您可以在AppDelegate创建类似的数组变量。 When MainViewController is loaded and the title array is computed, access AppDelegate and the title array on AppDelegate . 当MainViewController被加载和标题阵列计算，访问AppDelegate和在标题阵列AppDelegate 。 Now, directly access this title array like a local variable. 现在，像本地变量一样直接访问此标题数组。
As a side note, if this is a static array, why don't you simply set it in AppDelegate ? 附带说明一下，如果这是一个静态数组，为什么不简单地在AppDelegate设置它呢？
