ios - 快速替换 'Class'

Question

我正在从 objective-C 转向 Swift。

头文件是:

@interface RegisterType : NSObject 
{
    Class type;
    NSString *typeName;
    NSString *namespace;
    int typeId;
}

@property (nonatomic,retain) Class type;
@property (nonatomic,retain) NSString *typeName;
@property (nonatomic,retain) NSString *namespace;
@property (nonatomic) int typeId;

@end

实现是:

@implementation RegisterType

@synthesize type;
@synthesize typeName;
@synthesize namespace;
@synthesize typeId;

现在是 Swift 我的代码是:

class RegisterType {

    //var type: AnyClass
    var typeName: String = ""
    var namespace: String = ""
    var typeId: Int = 0

}

我的主要问题是我想替换我在 Objective-C 中使用的泛型类型“Class”。如何在 Swift 中替换它？我需要一个初始化方法吗？

如果我正确理解你的问题，我会这样做:

class RegisterType: NSObject {

    override init() {
        super.init()
        self.type = self.classForCoder
    }

    var type: AnyClass?
    var typeName: String = ""
    var namespace: String = ""
    var typeId: Int = 0

}

let xx = RegisterType()
println(xx.type) // prints "RegisterType"
