在 Swift 中逐行读取文本文件? [英] Read a text file line by line in Swift?

问题描述

我刚开始学习 Swift.我已经从文本文件中读取了我的代码，并且该应用程序显示了整个文本文件的内容.如何逐行显示并多次调用该行?

I 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 包含以下内容:

1. Banana 
2. Apple
3. pear
4. strawberry
5. blueberry
6. blackcurrant

以下是目前拥有的..

  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
    }

如果有其他方法可以做到这一点，请告诉我.将不胜感激.

If there is another way of doing this please let me know. It would be much appreciated.

推荐答案

Swift 3.0

if let path = Bundle.main.path(forResource: "TextFile", ofType: "txt") {
    do {
        let data = try String(contentsOfFile: path, encoding: .utf8)
        let myStrings = data.components(separatedBy: .newlines)
        TextView.text = myStrings.joined(separator: ", ")
    } catch {
        print(error)
    }
}

变量 myStrings 应该是数据的每一行.

The variable myStrings should be each line of the data.
