一,文本文件的内容。

- (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]); }
