How NSNotification can be used to verify NSTask status

Question

How can NSNotification be used to check the status of an NSTask? I know that there are several class methods in NSTask, but I don’t really understand how to implement them in a Cocoa application. Can someone help me?

Answer 1

The job will depend on you not reading what it sends to stdout / stderr. To do this, you need to create channels and install them using setStandardOutput.

Use [NSFileHandle readToEndOfFileInBackgroundAndNotify]and wait NSFileHandleReadToEndOfFileCompletionNotification. This will give you all the data in the callback.

Answer 2
