在 iOS SDK 中逐行读取文件 [英] Reading file line by line in iOS SDK

问题描述

我有一个 texfile 如下:

I have a texfile as follows:

line1
line2
line3
line4
line5
 ....

我想从文件中读取两个字符串数组，以便 line1, line3, line 5,... 进入 array1 和 line 2，第 4 行，第 6 行，... 进入 array2.数组的每个元素存储一行.

I want to read from file into two arrays of string so that line1, line3, line 5,... go into array1 and line 2, line 4, line 6,... go into array2. Each element of arrays stores one line.

推荐答案

Step 1) Read file ([NSString stringWithContentsOfFile:encoding:error:] )

Step 1) Read file ([NSString stringWithContentsOfFile:encoding:error:] )

步骤 2) 拆分字符串 ([NSString componentsSeparatedByCharactersInSet:[NSCharacterSet newlineCharacterSet]] )

Step 2) Split string ([NSString componentsSeparatedByCharactersInSet:[NSCharacterSet newlineCharacterSet]] )

第 3 步)遍历数组并插入到您的 2 个数组中

Step 3) Iterate over array and insert into your 2 arrays
