Answer 1

UICollectionView should be a better choice to display that kind of data in my opinion, but it's not compatible with ios5.

If you need an ios 5 compatibility, check out that answer: https://stackoverflow.com/a/16039194/2707614

Finally, to respond to your question, you can try to use Grand Central Dispatch as explained here

It should look like that (I don't have a computer to test):

dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0ul);

 dispatch_async(queue, ^{
for (int i=3; i<[[[self rssParser]rssItems]count]; i++)
    // for (int i=3; i<[titlearray count]; i++)
{
    if (i%3==0)
    {
        x=0;
        y++;
    }

    view=[[UIView alloc]initWithFrame:CGRectMake((x*250)+10, (y*306)+105, 244, 300)];
    [view setBackgroundColor:[UIColor whiteColor]];
    view.layer.borderColor=[[UIColor whiteColor]CGColor];
    view.layer.borderWidth=1.0;
    view.layer.cornerRadius = 5;
    view.layer.masksToBounds = YES;



    titlelabel=[[UILabel alloc]initWithFrame:CGRectMake(10, 10, 230, 20)];
    [titlelabel setText:[[[[self rssParser]rssItems]objectAtIndex:i-1]title]];
    [titlelabel setNumberOfLines:0];
    titlelabel.font=[UIFont boldSystemFontOfSize:14.0f];

    [titlelabel setBackgroundColor:[UIColor clearColor]];
    [titlelabel sizeToFit];


    datelabel=[[UILabel alloc]initWithFrame:CGRectMake(10, 62, 190, 20)];
    [datelabel setText:[[[[self rssParser]rssItems]objectAtIndex:i-1]pubDate]];
    [datelabel setNumberOfLines:0];
    datelabel.font=[UIFont fontWithName:@"arial" size:10.0f];
    [datelabel setBackgroundColor:[UIColor clearColor]];
    [datelabel sizeToFit];

    x++;

    dispatch_sync(dispatch_get_main_queue(), ^{
        [scroller addSubview:view];
        [view addSubview:titlelabel];
        [view addSubview:datelabel];
    });

}
});
