# cancelOperationsWithCompletionHandler:

Cancels any in-progress or pending sync operations.

## Declaration

```occ
- (void) cancelOperationsWithCompletionHandler:(void (^)()) completionHandler;
```

## Discussion

Discussion The sync engine processes cancellation requests asynchronously, meaning it’s possible for in-progress operations to complete even after this method returns.
