小编Wes*_*Cho的帖子

这是我到目前为止所处理的最可怕的错误.要明确:

1. 这很快,所以它不是".h"".m"问题
2. 我的编译源非常小,没有重复.
3. 我已经多次重新下载SDK但它永远不会工作.
4. 该项目只有两个框架:FBSDKCoreKit和LoginKit

有任何想法吗？什么是重复的？

我正在尝试使用UITextView的第一行设置我的笔记的标题.只有我的代码的最后一部分无效.

(如果你想知道为什么我除了使用30个字符的声明之外我还使用了"else",因为如果我没有输入至少30个字符的音符,则会出现错误)

 override func viewWillDisappear(animated: Bool) {
        detailItem!.noteText = self.textView.text


        if !self.textView.text.isEmpty {
            var textViewString:String = self.textView.text

            if let range = self.textView.text.rangeOfString("\n") {
                let rangeOfString = self.textView.text.startIndex ..< range.endIndex
                let firstLine = self.textView.text.substringWithRange(rangeOfString)

                detailItem?.noteTitle = firstLine
            } else {
                // take up to the first 30 characters as the title
                let length = count(self.textView.text)
                if length > 30 {
                    let firstLine = (textView.text as NSString).substringFromIndex(30)
                    detailItem?.noteTitle = firstLine
                } else {
                    let firstLine = (textView.text as NSString).substringFromIndex(length)
                    detailItem?.noteTitle = firstLine …

我试图将搜索结果显示在tableView上。我相信我已经正确解析了JSON，唯一的问题是结果不会显示在tableView上。

这是代码：

var searchText : String! {
        didSet {
            getSearchResults(searchText)
        }
    }

    var itemsArray = [[String:AnyObject]]()

    override func viewDidLoad() {
        super.viewDidLoad()

        self.tableView.delegate = self
        self.tableView.dataSource = self

        self.tableView.reloadData()

    }

    // MARK: - Get data

    func getSearchResults(text: String) {

        if let excapedText = text.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.URLQueryAllowedCharacterSet()) {

            Alamofire.request(.GET, "https://api.duckduckgo.com/?q=\(excapedText)&format=json")
                .responseJSON { response in
                    guard response.result.error == nil else {

                        // got an error in getting the data, need to handle it
                        print("error \(response.result.error!)")
                        return

                    }

                    let items = JSON(response.result.value!)

                    if let relatedTopics = …
