How do I read a text file in Objective-c?

Can someone provide a simplest-case example of read开发者_运维技巧ing a text file?

In Objective-C you can do something like

NSString* s = [[NSString alloc] initWithContentsOfFile:@"yourfile.txt" 
                                encoding:NSUTF8StringEncoding error:NULL];

If you really want plain C (and not objective-C), then:

#include <stdio.h>

#define BUFSIZE 100

int main(int argc, char *argv[]) {
    char buf[BUFSIZE];
    FILE *fp = fopen("filename.txt", "r");
    if (fp == NULL) {
        fprintf(stderr, "File not found\n");
        return 1;
    }
    while(fgets(buf, BUFSIZE, stdin) != NULL) {
        printf("%s", buf);
    }
    fclose(fp);
    return 0;
}
