一，文本文件的内容。

二，工程目录

三，ViewController.m

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    //读取文本文件
    [self readFromText];
}
#PRagma -mark -functions
//读取文本文件
-(void)readFromText
{
    NSError *error;
    NSString *textFieldContents=[NSString stringWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"chenlihua" ofType:@"txt"] encoding:NSUTF8StringEncoding error:&error];
    NSLog(@"--textFieldContents---%@-----",textFieldContents);
    if (textFieldContents==nil) {
        NSLog(@"---error--%@",[error localizedDescription]);
    }
    NSArray *lines=[textFieldContents componentsSeparatedByString:@"\n"];
    NSLog(@"number of lines in the file:%ld",[lines count]);
}

四，输出如下图所示：
