method called :

testes.m

-(void)addobject:(double)rephereanswer:(double)nbimportant{

Answer 1

Try this

[myLevelObject addobject:rephereanswer :nbimportant];

Answer 2

The signature of your method is actually addObject: :. Parameters are preceded by colons, so you'd call your method like so:

[myLevelObject addobject:rephereanswer :nbimportant];

However, in Objective-C, the prevailing style is to name all of your parameters, so you'd probably want to change your method to this:

- (void)addobject:(double)rephereanswer otherParam:(double)nbimportant;

In which case you'd call it like this:

[myLevelObject addobject:rephereanswer otherParam:nbimportant];

(A more descriptive name than otherParam is desirable, too.)
