Unrecognized selector sent to an instance?

Question

I have three methods which are taking parameters,

I am taking exception at this parameter giving,

[QuestionnaireView continueSingle:withQuestion:question:]: unrecognized selector sent to instance 0x8a4b1c0

What am i doing wrong? Its definition is also given in the header file.

Here is my code;

-(void) continueSingle:(id)sender withQuestion:(Question*)quest{

int counter = 0;

NSString * tempAnswer;

for(UIView* subview in [sender superview].subviews)
{

    if([subview isKindOfClass:[UIButton class]])
    {
        if([((UIButton*)subview) isSelected])
        {
            counter++;

            tempAnswer = [NSString stringWithFormat:@"%@",((UIButton*)subview).currentTitle];
        }
    }
}

}

Your mistake is here

-(void) continueSingle:(id)sender withQuestion:(Question*)quest

Because you are passing three parameter but you're receiving only two parameter. So you need to take 3 parameter. Like this..

-(void) continueSingle:(id)sender withQuestion:(Question*)quest question:(Question *)question1

i am passing as this; @selector(continueSingle:withQuestion:question:) – erdemgc Sep 13 '13 at 07:57
yes thats the problem. If you wanna only two parameter then you need to pass only two parameter like that @selector(continueSingle:withQuestion:) – Dharmbir Singh Sep 13 '13 at 07:58
