Write contents of array to a text file

Question

I want to write the contents of an array to a text file in my iPhone application. I can load the array from the text file but i want to allow deleting of content through the arr

Answer 1

Write the contents of your original array as shown below:

[firstArray writeToFile:@"/Users/sample/Untitled.txt" atomically:YES];

Whenever you want to retrieve and modify the array, retrieve the contents of the file int an NSMutableArray:

NSMutableArray *myArr = [NSMutableArray arrayWithContentsOfFile:@"/Users/sample/Untitled.txt"];
[myArr removeLastObject];  //Any modification you wanna do
[myArr writeToFile:@"/Users/sample/Untitled.txt" atomically:YES];
