Question

以前曾问过这个问题，但从来没有问过我的具体问题：

@property (readonly, copy, nonatomic) NSString *blogName;
@property (readonly, copy, nonatomic) NSString *blogEmail;
@property (strong, nonatomic) id<BlogParserDelegate> delegate; // This is my first problem
@property (strong, nonatomic) NSDictionary *blogSocialNetworkUserNames; // This is my second problem
@property (readonly, copy, nonatomic) NSString *blogLogoImageLink;
@property (readonly, copy, nonatomic) NSString *blogWebsite;

我不知道如何在Swift中实现两个标记的属性，我尝试了一些事情，这是我最后一次尝试不成功：

@NSCopying var blogSocialNetworkUserNames : NSDictionary!
    var blogLogoImageLink : String!

我得到的错误是：

Type 'WordPressParser' does not conform to protocol 'BlogParserProtocol'

有什么想法吗？

谢谢！

EDIT添加了所有代码：

协议：

@protocol BlogParserProtocol <NSObject>

@required

#pragma mark Properties
@property (readonly, copy, nonatomic) NSString *blogName;
@property (readonly, copy, nonatomic) NSString *blogEmail;
@property (strong, nonatomic) id<BlogParserDelegate> delegate;
@property (strong, nonatomic) NSDictionary *blogSocialNetworkUserNames;
@property (readonly, copy, nonatomic) NSString *blogLogoImageLink;
@property (readonly, copy, nonatomic) NSString *blogWebsite;

#pragma mark init methods
-(instancetype)initWithBlogName:(NSString*)blogName;

#pragma mark SFARSSParserProtocol methods

-(BOOL)isReachable;
-(void)readRSSAtURL:(NSString *)URL;
-(void)getCommentsFromArticleId:(NSString*)articleId;
-(void)addComment:(NSString*)comment
      toArticleId:(NSString*)articleId;

@end

符合协议的类：

class WordPressParser: NSObject, BlogParserProtocol {
    var blogName : String!
    var blogEmail : String!
    var delegate : AnyObject!
    var blogSocialNetworkUserNames : NSDictionary!
    var blogLogoImageLink : String!
    var blogWebsite : String!

    required init!(blogName: String!) {

    }

    func isReachable() -> Bool {
        return true
    }

    func readRSSAtURL(URL: String!) {

    }

    func getCommentsFromArticleId(articleId: String!) {

    }

    func addComment(comment: String!, toArticleId articleId: String!) {

    }
}

错误：

iPhone/ProjectName/WordPressParser.swift:11:1: Type 'WordPressParser' does not conform to protocol 'BlogParserProtocol'

Answer 1

当您实现所有必需的协议方法时，大多数情况下此错误都将消失。只需在WordPressParser类中编写所有必需的方法，然后尝试构建应用程序。它应该是成功的。

在swift中实现objective-c协议
