UIImageView goes black color and make all other images black

I added recently snapp开发者_如何学JAVAed images to my table view ..

And when i press any row of the tableview and navigate to another view and come back to my view then the image is converted to half black and when i repeat the process again then the whole image converted to black and some other images of tableview also goes black.

I am storing the images to document directory.

Is there anything stupid think which i am doing ?

In viewWillAppear, do this

- (void) viewWillAppear:(BOOL)animated
{
   [yourTableViewName reloadData];
}

if not worked well, its better to use Lazy Image Loading feature..
