I have an nsoperation class where I want to store that running operation into nsuserdefaults for later reference. How do I do that? Please help.

NSOperation is not compliant to NSCoding. You will have to encode/decode it yourself. However, think about what you are trying to accomplish here. There must be something really special or really wrong for you to need to save an NSOperation.

  • i wanted to get currently running operaton and cancel it, if a user click on cancel uploading button.. how do I achieve this? – Bharathi Jayakumar Oct 25 '12 at 09:48
  • You can cancel the operation from the NSOperationQueue using cancelAllOperations – J2theC Oct 25 '12 at 15:34
  • I want to cancel only one operation, that is currently running! Not all. As a workaround, I store currently running operation in the variable, and cancel it when required. First I thought I should store it in userdefaults, so that, even after, app terminated, it will be useful. Later realized that, it is not required.. Thanks anyway! :-) – Bharathi Jayakumar Oct 27 '12 at 08:24
  • AFNetworking's AFURLConnectionOperation (subclass of NSOperation) did conform to NSCoding, there is actually some case when archiving an operation does help. – zetachang Feb 15 '14 at 03:50
