PFImageView
links only to files stored on Parse.com and represented by PFFile
objects. You can't set cell.imagevieww.file
to a string and have it work.
If you are using normal URLs to arbitrary images on the web then you should use SDWebImage
(or a similar generic solution) for the image view on your cell.
With SDWebImage
you would replace:
cell.imagevieww.file= [object objectForKey:@"ImageURL"];
[cell.imagevieww loadInBackground];
with:
[cell.imagevieww setImageWithURL:[NSURL URLWithString:[object objectForKey:@"ImageURL"]]
placeholderImage:[UIImage imageNamed:@"placeholder.png"]];
