ios - SWIFT TableView 错误

Question

class MasterViewController: UITableViewController {

    let firstTable = [String]()
    let secondTable = [String]()

    var path = NSBundle.mainBundle().pathForResource("Chapters", ofType: "txt")
    var data = String(contentsOfFile:path, encoding: NSUTF8StringEncoding, error: nil)
    var content = (data)
    var line: [String] = content.componentsSeparatedByString("\n")

错误:

'MasterViewController.Type' does not have a member named 'path'

@dip 的下一个问题 >> 为什么表格打印初始空字符串？文本打印在第二个单元格中而不是从 0 开始

var path: String?
var data: String?
var TableView1 = [String]()

override func viewDidLoad() {
    super.viewDidLoad()

    self.path = NSBundle.mainBundle().pathForResource("textFile", ofType: "txt")
    self.data = String(contentsOfFile:path!, encoding: NSUTF8StringEncoding, error: nil)
    if var content = (data){
        //var line: [String] = content.componentsSeparatedByString("\n")
        var chp: [String] = content.componentsSeparatedByString("#")

        TableView1 += chp
    }...

Answer 1

对于计算属性，您必须通过 setter 方法访问，例如使可选的全局变量像

var path:String?

然后让我们从 inside viewDidload 中设置值，比如

self.path = NSBundle.mainBundle().pathForResource("Chapters", ofType: "txt")

您的错误将会消失!希望对您有所帮助!
