How can I edit a file in app bundle?

In my app, I load data from a CSV file stored in the bundle resources. However, I'd like to be able to update this file programmatically when the user taps the Update button. Is there a way to change a resource in the app bundle programatically? Here is the code I use to access the file:

    NSString *path = [[NSBundle mainBundle] pathForResource:@"query_result" ofType:@"csv"];
    NSArray *rows = [NSArray arrayWithContentsOfCSVFile:path];

First of all load file from bundle and after that just store in Document directory then you can make change on this file again save on document directory to access changed file.

Use this code copy from mainbundle to Document.

NSFileManager *fileManager = [NSFileManager defaultManager];
NSError *error;

NSString *dataPath = [[self applicationDocumentsDirectory] stringByAppendingPathComponent:@"tessdata"];
NSLog(@"Datapath is %@", dataPath);

// If the expected store doesn't exist, copy the default store.    
    if ([fileManager fileExistsAtPath:dataPath] == NO)
    {
        NSString *tessdataPath = [[NSBundle mainBundle] pathForResource:@"eng" ofType:@"traineddata"];
        [fileManager copyItemAtPath:tessdataPath toPath:dataPath error:&error];

    }

-(NSString*) applicationDocumentsDirectory{
    // Get the documents directory
    NSArray *dirPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *docsDir = [dirPaths objectAtIndex:0];
    return docsDir;
}

And then get the Saved file to change...

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

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