Question

我正在尝试实现用Swift编写的代码，看看它是否能够在我已经制作的Objective-C项目中实现我想要的内容，但是我在尝试翻译/重新翻译时遇到了麻烦它到Objective-C。

以下是swift中的代码：

override func viewDidLoad() {
    super.viewDidLoad()

    // Do any additional setup after loading the view, typically from a nib. 
    var feedContent:String! = "<h3>\(selectedFeedTitle)</h3>\(selectedFeedContent)"
    myWebView.loadHTMLString(feedContent, baseURL: nil)
} 

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject!) {
    if segue.identifier == "openWebPage" {
        let fwpvc: FeedWebPageViewController = segue.destinationViewController as! FeedWebPageViewController
        selectedFeedURL =  selectedFeedURL.stringByReplacingOccurrencesOfString(" ", withString:"")
        selectedFeedURL =  selectedFeedURL.stringByReplacingOccurrencesOfString("\n", withString:"")
        fwpvc.feedURL = selectedFeedURL
    }
}

我已将override func更改为-(void)，将super.viewDidLoad()更改为[super viewDidLoad];，并且它已接受但没有错误，但它给了我错误该代码中还有几行。我在网上寻找翻译技巧，但仍无法让他们工作。

它应该转换为类似的东西（未在实际的IDE中测试）：

- (void)viewDidLoad {
    [super viewDidLoad];

    // Do any additional setup after loading the view, typically from a nib. 
    NSString *feedContent = [NSString stringWithFormat:@"<h3>%@\</h3>%@", selectedFeedTitle, selectedFeedContent];
    [myWebView loadHTMLString:feedContent baseURL:nil];
} 

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
    if ([segue.identifier isEqualToString:@"openWebPage"]) {
        FeedWebPageViewController *fwpvc = (FeedWebPageViewController *)segue.destinationViewController;
        selectedFeedURL = [selectedFeedURL stringByReplacingOccurrencesOfString:@" " withString:@""];
        selectedFeedURL = [selectedFeedURL stringByReplacingOccurrencesOfString:@"\n" withString:@""];
        fwpvc.feedURL = selectedFeedURL;
    }
}
