从Swift 3中读取txt文件 [英] Reading from txt file in Swift 3

问题描述

例如，test.txt将包含：

/ b>

<'>'杰森16岁男子自编程

乔什15个男朋友艺术'''

所以我正在寻找一种方法来分别打印每一个单词和一行。如只印刷：

杰森

杰森是16$ / b
$ b Josh喜欢艺术

这是我到目前为止搜索到的

  if filepath = Bundle.main.path（forResource：test，ofType：txt）
 {
 do 
 {
 let contents = try String（contentsOfFile：filepath）
 print（contents [0]）
 
} 
 catch 
 {
 //内容无法加载
} 
} 
 else 
 {
 // example.txt not found！ 
 
 $ / code> 

感谢您的支持。一旦你把文件读入 contents ，你可以用下面的代码把它分解成行和单词： $ b $ pre $ let lines = contents.components（separateBy：\\\
）
为行{
让words = line.components（separatedBy：）
print（\（words [0]）is \（words [1]）and likes \（words [4]））
}





I want to know how to read from a txt file and print out specific parts of the file?

For example, "test.txt" will contain:

'''Jason 16 male self programing

Josh 15 male friend art'''

So I am looking for a way to print each word and line separately. Such as only printing:

"Jason"

"Jason is 16"

"Josh likes art"

This is what I got so far from searching around

if let filepath = Bundle.main.path(forResource: "test", ofType: "txt")
    {
        do
        {
            let contents = try String(contentsOfFile: filepath)
            print(contents[0])

        }
        catch
        {
            // contents could not be loaded
        }
    }
    else
    {
        // example.txt not found!
    }

Thank you for your support.

解决方案

Once you have read your file into contents you can break it into lines and words with code like:

let lines = contents.components(separatedBy: "\n")
for line in lines {
    let words = line.components(separatedBy: " ")
    print("\(words[0]) is \(words[1]) and likes \(words[4])")
}
