UIActivityViewController & UIDocumentInteractionController not showing options

Question

I am new to UIActivityViewController and perhaps I am missing a basic understanding. What I am trying to do is attached a csv, xml and vcard file to activity controller and show dropbox, google drive etc options. I have downloaded and installed dropbox, google drive etc apps on my iPhone.

Now when I launch UIActivityViewController all I see are default message and email app in my acitivity controller. How can I have other apps show up on their too? Do I need to install each and every apps individual SDKs and somehow incorporate them in my app?

This is what I wold like to see

but this is what I see instead.

Here's the code that I have tried so far

-(IBAction) dropBoxAction
{

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

    //CSV
    NSMutableString *fileNameStr = [NSMutableString stringWithFormat:@"test_CSV_Backup.csv"];
    NSString* csvDataFileStr = [documentsPath stringByAppendingPathComponent:fileNameStr];
    NSData *csvData = [NSData dataWithContentsOfFile:csvDataFileStr];

    //EXCEL
    NSMutableString *fileNameStr2 = [NSMutableString stringWithFormat:@"test_EXCEL_Backup.xml"];
    NSString* excelDataFileStr = [documentsPath stringByAppendingPathComponent:fileNameStr2];
    NSData *excelData = [NSData dataWithContentsOfFile:excelDataFileStr];

    //VCARD
    NSMutableString *fileNameStr3 = [NSMutableString stringWithFormat:@"test_VCARD_Backup.vcf"];
    NSString* vcardDataFileStr = [documentsPath stringByAppendingPathComponent:fileNameStr3];
    NSData *vcardData = [NSData dataWithContentsOfFile:vcardDataFileStr];


    //adding them all together
    NSMutableArray *sharingItems = [NSMutableArray new];
    [sharingItems addObject:csvData];
    [sharingItems addObject:excelData];
    [sharingItems addObject:vcardData];

    UIActivity *activity = [[UIActivity alloc] init];
    NSArray *applicationActivities = @[activity];

    UIActivityViewController *activityController = [[UIActivityViewController alloc] initWithActivityItems:sharingItems applicationActivities:applicationActivities];
    [self presentViewController:activityController animated:YES completion:nil];


}

As @rmaddy said, you should use UIDocumentInteractionController to replace UIActivityViewController, just like this:

UIDocumentInteractionController *dc = [UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:fileNameStr]];
[dc presentOptionsMenuFromRect:self.view.bounds inView:self.view animated:YES];
