阅读斯威夫特按行的文本文件行？ [英] Read a text file line by line in Swift?

问题描述

刚刚开始学习斯威夫特，我有我的code从文本文件阅读，和App显示整个文本文件的内容。我如何通过线显示行并在该​​行多次调用？

Just started learning Swift, I have got my code to read from the text file, and the App displays the content of the Entire Text file. How can I display line by line and call upon that line multiple times?

TextFile.txt的含有以下内容：

TextFile.txt contains the following.

1. 香蕉


2. 苹果


3. 梨


4. 草莓


5. 蓝莓


6. 黑茶

以下是目前有..

  if let path = NSBundle.mainBundle().pathForResource("TextFile", ofType: "txt"){
        var data = String(contentsOfFile:path, encoding: NSUTF8StringEncoding, error: nil)
            if let content = (data){
                TextView.text = content
    }

此外，如果有另一种方式，这样做的请告诉我。大部分AP preciated

also if there is another way, of doing this please let me know. Much appreciated

推荐答案

您可以试试：

if let path = NSBundle.mainBundle().pathForResource("TextFile", ofType: "txt"){
    var data = String(contentsOfFile:path, encoding: NSUTF8StringEncoding, error: nil)
    if let content = data {
         let myStrings = content.componentsSeparatedByCharactersInSet(NSCharacterSet.newlineCharacterSet())
         TextView.text = myStrings[0]
    }
}

变量 myStrings 应该是每一行数据。

所使用的code是：
通过线的iOS SDK文件读取的行写在Obj- C和使用的NSString
