obj-c的类自定义初始化程序不会出现在swift中

我很快就知道了，我没有使用objective-c的经验。这是一个Objective-c类，我想在我的swift代码中使用它 WebSocket.h：

#import <Foundation/Foundation.h>
@class HTTPMessage;
@class GCDAsyncSocket;
#define WebSocketDidDieNotification  @"WebSocketDidDie"
@interface WebSocket : NSObject
{
    dispatch_queue_t websocketQueue;
    HTTPMessage *request;
    GCDAsyncSocket *asyncSocket;
    NSData *term;
    BOOL isStarted;
    BOOL isOpen;
    BOOL isVersion76;
    id __unsafe_unretained delegate;
}
+ (BOOL)isWebSocketRequest:(HTTPMessage *)request;
- (id)initWithRequest:(HTTPMessage *)request socket:(GCDAsyncSocket *)socket;

@property (/* atomic */ unsafe_unretained) id delegate;
@property (nonatomic, readonly) dispatch_queue_t websocketQueue;

- (void)start;
- (void)stop;

- (void)sendMessage:(NSString *)msg;
- (void)sendData:(NSData *)msg;
- (void)didOpen;
- (void)didReceiveMessage:(NSString *)msg;
- (void)didClose;
@end


@protocol WebSocketDelegate
@optional
- (void)webSocketDidOpen:(WebSocket *)ws;
- (void)webSocket:(WebSocket *)ws didReceiveMessage:(NSString *)msg;
- (void)webSocketDidClose:(WebSocket *)ws;
@end

我已将上面的头文件添加到XXXX-Bridging-Header.h中，如此

#import "WebSocket.h"

但是当我想尝试实例化WebSocket类时，我在自动完成中看不到任何初始化器： enter image description here

尝试替换

- (id)initWithRequest:(HTTPMessage *)request socket:(GCDAsyncSocket *)socket;

带

- (id)initWithRequest:(HTTPMessage *)request socket:(GCDAsyncSocket *)socket NS_DESIGNATED_INITIALIZER;

答案 1 :(得分：1)

我认为您的问题在于您没有导入依赖项：

<html>
<body>
    Hello, <%= name -%>
    <br/>
</body>
</html>
Swift不知道

，因为桥接标头或@class HTTPMessage; @class GCDAsyncSocket; 都没有导入/包含它们。因此，在Swift中无法访问使用它们的方法。
