Read Text File in Document Folder - Iphone SDK

I have this code below:

    NSString *fileName = [[NSUserDefaults standardUserDefaults] objectForKey:@"recentDownload"];
    NSString *fullPath = [NSBundle pathForResource:fileName ofType:@"txt" inDirectory:[NSHomeDirectory() stringByAppendingString:@"/Documents/"]];
    NSError *error = nil;

    [textViewerDownload setText:[NSString stringWithContentsOfFile:fullPath encoding: NSUTF8StringEncoding error:&error]];

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

    NSString *myPathDocs =  [documentsDirectory stringByAppendingPathComponent:@"myfile.txt"];

    if (![[NSFileManager defaultManager] fileExistsAtPath:myPathDocs])
    {
        NSString *myPathInfo = [[NSBundle mainBundle] pathForResource:@"myfile" ofType:@"txt"];
        NSFileManager *fileManager = [NSFileManager defaultManager];
        [fileManager copyItemAtPath:myPathInfo toPath:myPathDocs error:NULL];
    }       

    //Load from File
NSString *myString = [[NSString alloc] initWithContentsOfFile:myPathDocs encoding:NSUTF8StringEncoding error:NULL];

This worked for me

Anyway, thank you all..

The NSBundle class is used for finding things within your applications bundle, but the Documents directory is outside the bundle, so the way you're generating the path won't work. Try this instead:

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
                                                     NSUserDomainMask,
                                                     YES);

NSString *fullPath = [[paths lastObject] stringByAppendingPathComponent:@"recentDownload.txt"];
