问题
I'm a relatively new iOS developer, with most of my previous experience coming from .NET. My application is a canvas like system in that there is a parent UIView that contains all the objects the user is placing/resizing/etc as subviews. I want to be able to save these positions/configurations to named files.
In .NET, I would have simply subclassed UIView, given it a "title" property, then serialized this to file, and then deserialized them to load them back, but in Cocoa I'm quite lost.
Originally I thought I could do this using NSCoding, but this doesn't seem to be a good solution for multiple file saving.
So I looked at Core Data, but I'm not sure how I can create Core Data objects of existing Cocoa UIKit classes like UIView.
I've spent a while googling and can't find any information about this kind of predicament. What should I use, and what is the best way to go about it?
回答1:
You probably could do it with NSKeyedArchiver, since UIView implements NSCoding. A more MVC-oriented design, however, would be to have the user manipulate a data model by moving the views around. To save, you'd archive the model rather than the views themselves.
