在
Swift中,String结构也被视为类对象,就像使用NSCoder encodeObject(_：forKey :)方法一样.我知道String直接与objective-c类NSString桥接,但有没有办法制作一个行为相似的自定义结构？也许将它连接到一个自定义类？我希望能够做到这样的事情：
struct SortedArray <Value: Comparable> {}
// Would I need to create a bridge between
// SortedArray and NSSortedArray? Can I even do that?
class NSSortedArray <Value: Comparable> : NSObject,NSCoding {
required init?(coder aDecoder: NSCoder) {}
func encodeWithCoder(aCoder: NSCoder) {}
}
class MyClass : NSObject,NSCoding {
private var objects: SortedArray<String> = SortedArray<String>()
required init?(coder aDecoder: NSCoder) {
guard let objects = aDecoder.decodeObjectForKey("objects") as? SortedArray<String> else { return nil }
self.objects = objects
}
func encodeWithCoder(aCoder: NSCoder) {
aCoder.encodeObject(objects,forKey: "objects")
}
}
