BlankView | 自定义选词填空view

Welp, I think I figured out a solution.

The issue seems to have been with the items in the BasicListView being wrapped in @State instead of @Binding, and the ViewBuilder block having the type ([ListItem]) -> Content instead of (Binding<[ListItem]>) -> Content. The original setup worked for initializing from static data (MockListItem.all) pulled from outside the block, but when using data passed into the block, somewhere between the init and body being called it was being discarded/reset. Instead, I changed the items in BasicListView to a @Binding, and now init by passing in a binding of the @State var list in BlankView. Here is the updated code:

When a closure parameter is optional, it becomes @escaping, so mark your animations parameter with @escaping:

Set translatesAutoresizingMaskIntoConstraints of the subview to false.

Your code doesn't work because customView is nil in most cases.

If you want to set a navigation item to a UIImage, create a new UIBarButtonItem from the image, and then assign the bar button item.

For example, from a UIImage:

Skip my mind that i could just change first argument and set is as new page.

I got this working and wanted to share with anyone who may be doing the same thing or similar. I am not sure if this is the best way but I am happy it works.

I did two things. One, I saved the AreaRegistrationContext to a static member for later use. Two, I did not try to add/remove the existing mapping. Instead, I just added a new one.

In my case, a new customer is not added too often so there will not be too many mappings for this area.

Here is my final class.
