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：
