How to use NSRunLoop in Objective-C and how to use to change the value of some variables?

Thanks

We usually wait for a variable to change Will not use an NSRunLoop in production. Can use a callback.

However, in the unit test code we have the following: 

  NSDate * twoSecondsFromNow = [NSDate dateWithTimeIntervalSinceNow: 2.0]; While the (! Callback Inquake & Error! Accelerator & amp; Runcount- & amp; amp; [[NSRunLoop currentRunLoop] RunMode: NSDefaultRunLoopMode before: DOSCFFMNM]] {twoSecondsFromNow = [NSDT DateEight TimeInternationalSync: 2.0];}

The code waits until our callback is implemented, an error has occurred, or we have waited for a period of 2 seconds, we use it to test the delegates who callback

As I Scope said I would not do this in production code.

The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.
