Objective-C. Read text file.

This small program reads the text file:

#import <Foundation/Foundation.h>

int main (int argc, const char * argv[]) 
{
    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];

    NSString* fileName = @"text.txt";
    NSString *fileString = [NSString stringWithContentsOfFile: fileName];

    NSArray *lines = [fileString componentsSeparatedByString:@"\n"];    

    [pool drain];
    return 0;
}

How to make this program:
1. Launch Xcode
2. Menu File -> New Project -> Command Line -> Foundation Tool.
3. Put this program into main.m file.

The text file should be near the executable file. The text will be in fileString.

Of course, the standard C will work too:

#import <Foundation/Foundation.h>

int main (int argc, const char * argv[]) 
{
    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
    char buffer[1024];
    FILE* file = fopen("text.txt", "r");
    if (file != 0)
    {
        while(fgets(buffer, 1024, file) != NULL)
        {      
            NSString* string = [[NSString alloc] initWithCString: buffer];
            NSLog(string); 
            [string release];
        }
        fclose(file);
    }
    [pool drain];
    return 0;
}
