Question

I know there have been questions asked on this topic but they all differ slightly
what I want is a simple method that you pass an x value a y value and a quadrant value and it returns angle so far I have…

-(float)getAngle: (float)x  yvalue:(float)y Quadrant:(float) quadrant{

float angle=0.0;
 if(quadrant==1){

  }

  NSLog(@"%f",x);
 return angle;
}  

im not concerned about calculations at this point. I just want to know how to properly declare this method, because it wont let me name the first parameter.

Answer 1

Your code, as is, would work fine. Suppose you have a method like what you posted:

-(float)getAngle: (float)x  yvalue:(float)y Quadrant:(float) quadrant{

    float angle=0.0;
    if(quadrant==1){

    }

    NSLog(@"%f",x);
    return angle;
}  

You could call this within the current class, and receive the returned value, like so:

// sample values added
float result = [self getAngle:-1.0 yvalue:0.5 Quadrant:2.0];
NSLog(@"%f",result);
