AFNetworkActivityIndicatorManager doesn't decrement since table cell recycling cancels image request
afnetworking, ios
Solution
You shouldn't need to do this all you need to do is call:
AFNetworkActivityIndicatorManager.sharedManager.enabled = YES;
in you AppDelegate application:didFinishLaunchingWithOptions: and then AFNetworking looks after hiding and showing the indicator as and when network connections start and stop.
Problem
I'm using `UIImageView+AFNetworking:setImageWithURLRequest` to load images into table view cells. It's working great and I tried using `AFNetworkActivityIndicatorManager` as in the example below to display the activity indicator while the images are loading. ``` [[AFNetworkActivityIndicatorManager sharedManager] incrementActivityCount]; [imageView setImageWithURLRequest:request placeholderImage:[UIImage imageNamed:placeholder] success:^(NSURLRequest *request, NSHTTPURLResponse *response, UIImage *image) { [[AFNetworkActivityIndicatorManager sharedManager] decrementActivityCount]; } failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error) { [[AFNetworkActivityIndicatorManager sharedManager] decrementActivityCount]; } ]; ``` The problem I've run into is when scrolling quickly through the table view AFNetworking cancels certain requests and the `AFNetworkActivityIndicatorManager` never gets decremented. Canceling requests does keep things fast and appears to be by design: "As table view cells are recycled, for instance, setting a new image URL will automatically cancel the previous request." https://github.com/AFNetworking/AFNetworking/wiki/Introduction-to-AFNetworking Is there a way to detect the cancellation so I can decrement the `AFNetworkActivityIndicatorManager` or is there a better way to make sure the requests and activity indicator stay in sync? Thanks!
