Reading file line by line in iOS SDK

问题

I have a texfile as follows:

line1
line2
line3
line4
line5
 ....

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.

回答1:

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

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

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