Setting Title for Row in PickerView

Question

I am struggling trying to set my titleForRow in my PickerView. Currently, I have a picker that accesses a user's playlist data. Then I want to transfer it to the picker. However, I know the picker data is correct because of the didSelectRow method. I have been unlucky in trying to display the actual data in the PickerView.

**I have edited my code to what I have now. Currently, Purchased is repeated over and over inside my pickerview. Is there a way to fix it?

   -(NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component
{
    return [_roundArray count];
    return [_timeArray count];

    MPMediaQuery *myPlaylistsQuery = [MPMediaQuery playlistsQuery];
    NSArray *playlists = [myPlaylistsQuery collections];

    return [playlists count];

}

-(void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
{
    if (pickerView.tag == 1) {
        lblRound.text = [_roundArray objectAtIndex:row];
    }
    else if (pickerView.tag == 2) {
        lblTime.text = [_timeArray objectAtIndex:row];
    }
    else if (pickerView.tag ==3) {

        MPMediaQuery *myPlaylistsQuery = [MPMediaQuery playlistsQuery];
        NSArray *playlists = [myPlaylistsQuery collections];

        for (MPMediaPlaylist *playlist in playlists) {
            lblPlaylist.text = [playlist valueForProperty: MPMediaPlaylistPropertyName];
    }
}

}

    NSString *title;

    if (pickerView.tag == 1) // this is otherPickerview
    {
        title=[_roundArray objectAtIndex:row]; // your logic to get title for otherpickerview

    }
    else if (pickerView.tag == 2) // this is citysPickerview
    {
        title=[_timeArray objectAtIndex:row]; // your logic to get title for cityspickerview

    }
    else if (pickerView.tag == 3)
    {
        [self showPlaylistData];

        MPMediaQuery *myPlaylistsQuery = [MPMediaQuery playlistsQuery];
        NSArray *playlists = [myPlaylistsQuery collections];

        for (MPMediaPlaylist *playlist in playlists)
            title = [playlist valueForProperty: MPMediaPlaylistPropertyName];
    }

    return title;

}

Answer 1

The problem is that you have failed to set this class up as your picker view's data source, and you have failed to implement the data source methods. Thus, no data. Consult the documentation on UIPickerViewDataSource. (Or just look at any working example and base your code on that.)
