Nsoperations benifits

NSOperation provides several benefits for managing concurrent operations in your app. Here are some key advantages:

1. Concurrency Management: NSOperation allows you to manage the execution of multiple operations concurrently. You can set dependencies between operations, ensuring that certain tasks are completed before others begin.

2. Operation Queues: NSOperation works with NSOperationQueue, which handles the scheduling and execution of operations. This helps in managing the execution order and the number of concurrent operations.

3. Cancellation: NSOperation provides built-in support for cancelling operations. You can cancel an operation at any time, and the operation can check its cancellation status and stop executing if needed.

4. KVO Compliance: NSOperation is Key-Value Observing (KVO) compliant for several of its properties, such as isFinished, isExecuting, and isCancelled. This allows you to observe changes to these properties and update your UI or other parts of your app accordingly.

5. Prioritization: You can set the priority of operations, allowing more important tasks to be executed before less important ones.

6. Thread Safety: NSOperation and NSOperationQueue are designed to be thread-safe, making it easier to manage operations in a multi-threaded environment.
