iOS Build a Photo Browser iPhone App Gestures Creating a Detail View Controller

Now a single tap opens each picture, I can't double-tap to 'Like' a picture.

Hi all,

I've been working through the Photo Bomber application with iOS and Instagram.

We added gesture functionality to spot a double-tap and to like the photo this was done on. Subsequently, we added a single tap to enlarge the pic into its own view, full-size.

In my app, the single tap overrides the double-tap so I can no longer 'Like' a pic.

Did I miss something?

Thanks,

Steve.

In the THPhotoCell.m file you'll see the code below which indicates the like gesture was updated to be a long press instead of a double tap. Don't remember if this was covered in the course or not.

- (void)like:(id)sender {
    UILongPressGestureRecognizer *longPress = (UILongPressGestureRecognizer *)sender;
    if ( longPress.state == UIGestureRecognizerStateEnded) {
        NSURLSession *session = [NSURLSession sharedSession];
        NSString *accessToken = [[NSUserDefaults standardUserDefaults] objectForKey:@"accessToken"];
        NSString *urlString = [[NSString alloc] initWithFormat:@"https://api.instagram.com/v1/media/%@/likes?access_token=%@", self.photo[@"id"], accessToken];
        NSURL *url = [[NSURL alloc] initWithString:urlString];
        NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
        request.HTTPMethod = @"POST";
        NSURLSessionDataTask *task = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
            dispatch_async(dispatch_get_main_queue(), ^{
                [self showLikeCompletion];
            });
        }];
        [task resume];
    }
}
