Hi all,

I am working with a Quartz Composer composition in my Cocoa project via a QCRenderer. I have had no problems using [myQCRenderer setValue:myValue forInputKey:myKey] to set values of inputs in the quartz composition. However, when I try to read the current values of inputs or outputs I have tourble.

I am trying to do something like:

NSNumber* myQuartzOutput = [_myQCRenderer valueForOutputKey:@"myOutput"];
NSString* output = [NSString stringWithFormat:@"%d", myQuartzOutput];
NSLog(output);

Using either valueForOutputKey or valueForInputKey, the printed output is always something along the lines of: "350369552" or "350365488" etc. Which my guess would be they are memory addresses or the result of null values being passed, I'm not sure. If I assign myQuartzOutput the value 19, then 19 prints just like it is supposed to, so that narrows the problem down a bit. Does anyone have any ideas what I'm doing wrong? Any help would be appreciated.

Thanks.

The format specifier "%d" makes NSString expect an int argument. You are passing an NSNumber to that, which makes it interpret the NSNumber's address as an int. What you want is [myQuartzOutput intValue].

Thanks for the quick reply,

I tried your suggestion and changed the line to:

output = [NSString stringWithFormat:@"%d", [myQuartzOutput intValue]];

Now the output of the program is always 0 instead of the long numbers that were printed previously. I suppose this is progress, however it is still not the expected value that should be getting printed. I double checked the quartz file and made sure that the output port was indeed published under the name that I was trying to access it by, and that the value was getting to it. Any ideas?

Thanks.
