thumbnailImageAtTime is deprecated in iOS7. Alternative?

I got it to work using @aarondaub7's suggestion

Step 1. Add the AVFoundation.framework in the build phases panel.

Step 2. Update InboxViewController.h

#import <AVFoundation/AVFoundation.h>

Step 3. Update InboxViewController.m after the "prepareToPlay" method.

AVAsset *videoThumbnail = [AVAsset assetWithURL:fileURL];

[AVAssetImageGenerator assetImageGeneratorWithAsset:videoThumbnail];

Apple Docs -- AVAssetImageGenerator

Amit, thank you for the pointer.

Wait I'm still kind of confused. I have created the method in Inbox.m and declared it in the header but have no idea how to add it. Shown below is my code and I have commented the part where I'm trying to add it. Xcode won't take in self.moviePlayer.

<p>
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    self.selectedMessage = [self.messages objectAtIndex:indexPath.row];
    NSString *fileType = [self.selectedMessage objectForKey:@"fileType"];
    if ([fileType isEqualToString:@"image"]) {
        [self performSegueWithIdentifier:@"showImage" sender:self];
    } else {
        // File Type is video
        PFFile *videoFile = [self.selectedMessage objectForKey:@"file"];
        NSURL *fileUrl = [NSURL URLWithString:videoFile.url];
        self.moviePlayer.contentURL = fileUrl;
        [self.moviePlayer prepareToPlay];


        [self.moviePlayer thumbnailFromVideoAtURL:fileUrl]; //How do I add this??


        // Add it to the view controller so we can see it.
        [self.view addSubview:self.moviePlayer.view];
        [self.moviePlayer setFullscreen:YES animated:YES];
    }
}

</p>

Also how does just adding in: (from the comment of Charlie Hield)

<b> AVAsset *videoThumbnail = [AVAsset assetWithURL:fileURL];

[AVAssetImageGenerator assetImageGeneratorWithAsset:videoThumbnail]; </b>

after the "prepareToPlay" method differ from using the method from the stack flow link? Does it by default set the thumbnail capture time also at 0?

just place with

[self.moviePlayer requestThumbnailImagesAtTimes:@[@0] timeOption:MPMovieTimeOptionNearestKeyFrame];

Jack Crane If you click on the Stack overflow link it takes you to the answer. The answer is a method which takes in a URL and returns a UIImage which can be assigned to the image property of a UIImageView.
