推荐答案

如果您要保存对象的特定状态，可以存储NSUserDefaults中的字符串，并根据您的字符串设置对象。或者，您可以创建xib文件，它会自动存储您的对象吗？

If your point is to save specific states of your objects, you can store strings in the NSUserDefaults and set the objects according to your strings. Alternatively, you can create the xib files, which automatically will store your objects?
