【读书笔记】iOS-读取文本文件

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：
