Now i am retrieving file from document directory by specific name in iOS with following code.

NSMutableArray *arrayToSearch = [[NSMutableArray alloc] init];

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSError * error;

    arrayToSearch = (NSMutableArray *)[[NSFileManager defaultManager] contentsOfDirectoryAtPath:[NSString stringWithFormat:@"%@/Manual.txt",documentsDirectory] error:&error];

I am sure i have the Manual.txt file in document directory.

However it doesn't show anything in tableView.

I also reload tableView.

Is there anything wrong?

The method is contentsOfDirectoryAtPath:. Read the name of the method. Read the description in the docs. The path you pass must reference a directory, not a file.

What you are trying to do doesn't make sense logically. If you know a specific file, then why search for it? Why create an array?

If you want to see if the file exists, use the fileExistsAtPath: method of NSFileManager.

If you just want the filename in the array then do:

NSString *filename = [documentsDirectory stringByAppendingPathComponent:@"Manual.txt"];
[arrayToSearch addObject:filename]; // since the array was pre-allocated

Please don't use stringWithFormat to create the filename. Use the proper NSString path methods like I did above.

Yes bro. i got it. But I am using with NSMutableArray. Can i use with @[filename]; bro? – Sabo Jun 24 '13 at 19:13
    
Since you actually allocated the mutable earlier, you should do [arrayToSearch addObject:filename];. I'll update my answer. – rmaddy Jun 24 '13 at 19:14
