How do I parse a text file in Objective-C?

Question

I need to parse a text file, one line at a time. Also, is there EOF in Objective-C?

Answer 1

Something like this might work for you:

NSString *fileContents = [NSString stringWithContentsOfFile:@"myfile.txt"];
NSArray *lines = [fileContents componentsSeparatedByString:@"\n"];

This will give you an array where each element is a line of the string.

Answer 2

Objective-C is a proper extension of C. Any C program is a valid Objective-C program. Among other things, this means that EOF defined in the standard C header "stdio.h" is an EOF marker in Objective-C as well.

Answer 3

stringWithContentsOfFile is deprecated.

Here is an updated answer:

NSError* error;
NSString *fileContent = [NSString stringWithContentsOfFile:txtFilePath encoding:NSUTF8StringEncoding error:&error];
NSArray *lines = [fileContent componentsSeparatedByString:@"\n"];
