capture multiple arguments in unit test

I am using OCMock 3 to do unit testing. I have a very simple function named processInfo to test:

@implementation MyService
// in my test case, I want to test this function
-(void) processInfo{
  ...
  [self handleDataWith:infoData name:someName];
}

-(void) handleDataWith:(NSData*)data name:(NSString*)name{
  ...
}

My test case is supposed to be something like this to capture argument (inspired by this answer):

-(void) testProcessInfo {
  id serviceMock = [OCMockObject mockForClass:[MyService class]];
  // Wow!Wow! wait, the answer I linked above only talk about how to capture a single argument, 
  //BUT I have two arguments to capture, how to do then?
  OCMExpect([serviceMock handleDataWith:[OCMArg checkWithBlock:^(id value){ 
    // Capture argument here...but what about several arguments?
}]]);

The answer I linked above tells how to use [OCMArg checkWithBlock:^(id value)] to capture a single argument, but I want to capture two arguments. How to do it then?

In general, I can hardly find a well documented way on internet about how to capture multiple arguments in unit test with OCMock v3. Anyone knows how to do this?

As I mentioned in a comment to the answer to one of your other questions (Check argument value passed into function in unit test), you have to use andDo.
