NSString *documentsDirectoryPath = [paths objectAtIndex:0];
NSFileManager *manager = [NSFileManager defaultManager];
self.frlistName2 = [[manager contentsOfDirectoryAtPath:documentsDirectoryPath error:nil]pathsMatchingExtensions:[NSArray arrayWithObject:@"txt"]];
NSString *obj = @".txt";
frlisturls2 = [[NSMutableArray alloc] initWithObjects:nil];
NSString *temp;
NSMutableString *mp3Path = [[NSMutableArray alloc] init];
int j =0;
for(int i =0 ; i< [frlistName2 count]; i++)
{
    mp3Path  = [NSMutableString stringWithString:documentsDirectoryPath];
    [mp3Path appendString:@"/"];

    temp = [frlistName2 objectAtIndex:i];
    if([temp hasSuffix :obj])
    {
        [mp3Path appendString: temp];
        [frlisturls2 addObject: mp3Path];
        j++;
    }
    [mp3Path release];
}
NSLog(@"frlisturls2 is%@:",frlisturls2);
[super viewDidLoad];
fileName = [[NSString alloc]init];
fileName=[frlisturls2 objectAtIndex:iRow ];
NSLog(@"the fileName is %@",fileName);

This is how I read the txt file to txtView

But sometimes the file can't open by text editor , 

NSString *filePath = @"Users/macbookpro/Library/Application
 Support/iPhone Simulator/4.3.2/Applications/ ...
 /Documents/sample.txt"; 
NSString *txtContent = [[NSString alloc]
                                    initWithContentsOfFile:filePath
                                    encoding:NSUTF8StringEncoding
                                    error:&error];

load txtContent to your textView.text
