xcode - 从文件更改导航栏的标题

Question

所以我有一个导航栏，并且希望能够更改它的标题并将文本文件的内容显示为标题。我打算使用此代码来访问标题 self.navigationItem.title = "YourTitle" 并想知道是否有人可以解决我如何混合从文本文件检索的以下代码:

 let descriptionTextUrl = NSURL(string: "https://wordpress.org/plugins/about/readme.txt")
    let descriptionTextRequest = NSURLRequest(URL: descriptionTextUrl!)

    NSURLConnection.sendAsynchronousRequest(descriptionTextRequest, queue: NSOperationQueue.mainQueue()) {
        (response, data, error) in
        dispatch_async(dispatch_get_main_queue())
            {self.DescriptionText.text = NSString(data: data, encoding: NSUTF8StringEncoding)! as String
                return}

谢谢

Answer 1

只需将 self.DescriptionText.text = 替换为 self.navigationItem.title =

这是完整的代码:

 //NavBar
    let navigationBarUrl = NSURL(string: "https://wordpress.org/plugins/about/readme.txt")
    let navigationBarRequest = NSURLRequest(URL: navigationBarUrl!)

    NSURLConnection.sendAsynchronousRequest(navigationBarRequest, queue: NSOperationQueue.mainQueue()) {
        (response, data, error) in
        dispatch_async(dispatch_get_main_queue())
            {self.navigationItem.title = NSString(data: data, encoding: NSUTF8StringEncoding)! as String
                return}
    }
