Slow loading the images from URL in UITAbleView.

Question

I\'m loading the images from URL in UITableView. But it\'s very slow when loading an view. Here\'s an example,

UIImage *image = nil;
image = [UIImage imageW         


        

Answer 1

//Make use of dispatch queue for faster processing of data. add this in viewDidLoad

    dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0), ^{
    NSData * data=[NSData dataWithContentsOfURL:[NSURL URLWithString:imageUrl]];
    [self performSelectorOnMainThread:@selector(setImage:) withObject:data waitUntilDone:YES];
});

//once data is got set the image and reload tableview

-(void)setImage:(NSData *)responseData
{
image = [UIImage imageWithData:responseData];
[tableView reloadData];
}
