typedef NS_ENUM(NSUInteger, NetErrorType) {
    NetErrorTypeNone NS_SWIFT_NAME(None),
    NetErrorTypeNetError NS_SWIFT_NAME(NetError) ,
};

@interface YKBaseUIViewController : UIViewController 
- (void)handleConnectItem:(YKConnectionItem *)connectionItem withParser:(YKJsonParser *)parser NS_SWIFT_NAME(handleNetResponse(connectionItem:parser:));

@end

在swift中调用如下：

NetErrorType.None
let baseUIViewController : YKBaseUIViewController = YKBaseUIViewController()
baseUIViewController.handleNetResponse(connectionItem: nil, parser: nil)

public static func showMyInfo(age: Int, address: String) -> String{
        return "ksnowlv"
