Objective c ERROR: incompatible types for argument 2 of 'NSRunAlertPanel'

Here is the code:

float charlieSoundVolume;
charlieSoundVolume = [charlieSoundLevel floatValue];

NSRunAlertPanel(@"CHARLIE",charlieSoundVolume, @"", @"", @"Ok");

This gives me the error: incompa开发者_高级运维tible types for argument 2 of 'NSRunAlertPanel'

Will NSRunAlertPanel not accept floats?

Any ideas??

I'm not sure why you'd be surprised that it doesn't take floats given the documentation:

NSInteger NSRunAlertPanel (
   NSString *title,
   NSString *msg,
   NSString *defaultButton,
   NSString *alternateButton,
   NSString *otherButton,
   ...
);

Pass a string.
