I'm having problems with the quiz Viewing Images from Parse.com

``Quiz- Viewing Images

Fill in the blanks in the following code that sets a UIImageView with an image from Parse:

PFFile *imageFile = [self.photo objectForKey:@“file”]; NSURL *fileUrl = [[NSURL alloc] initWithString:__________.ur]l; NSData *imageData = [NSData dataWithContentsOfURL: ______]; self.imageView.image = [UIImage _________:imageData];

I thought the blanks should be in the first 1. file.url 2nd- fileUrl 3rd- fileWithData? 

This one as well Fill in the blanks to 1) set the 'comments' property to the array returned in this block, and 2) reload the table view: 
 [query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) { if (error) { // Skip! } else { self.comments = ; [self.tableView ]; NSLog(@"Retrieved %d messages", [self.messages count]); } }]; I thought it should be in the 1st- blank comments and in the second blank reloadData

Hello Andrew,

you're close, instead of file.url it already has the .url part so simply add that, second part is ok, and for the third part fileWithData isn't what you're looking for, you're trying to set the image so using fileWithData when you should be using imageWithData.

Hope this helps, Kai
