You can also use SDWEBIMAGE. thus you can use 

[cell.imageView setImageWithURL:[NSURL URLWithString:@"Your image url"]
                   placeholderImage:[UIImage imageNamed:@"placeholder.png"]];

see this link.

  • You can set images to the UIIMAGE and Fill your array with that UIIMAGE. Then give it to the your cell`s ImageView. – Vishal Sharma Apr 07 '14 at 10:44

  • Get Your number of url`s into any array. Then [cell.imageView setImageWithURL:[NSURL URLWithString:[Yourarray objectatIndex:IndexPath.Row] ] placeholderImage:[UIImage imageNamed:@"placeholder.png"]]; – Vishal Sharma Apr 09 '14 at 08:44

  • it bas a thread on the NSArray *images = @["images array urls"],what's wrong with my code? – user3376284 Apr 09 '14 at 09:42
  • You have to same or more number of objects in that array then number of rows in your TableView. – Vishal Sharma Apr 09 '14 at 09:44
  • Alloc init your Array at out of cellForItemAtIndexPath method. i.e. feed your images array in your ViewDidLoad method. – Vishal Sharma Apr 09 '14 at 09:46
