Question

Hi I need to make a 2D arch. Where I am getting a problem here

arc.path=[UIBezierPath bezierPathWithArcCenter:CGPointMake(50, 100)
                                                  radius:80.0
                                                  startAngle:DEGREE(65)
                                                  endAngle:DEGREE(90)
                                                  clockwise:NO].CGPath;

I am getting an error that

Undefined symbols for architecture i386: "_DEGREE", referenced from:

I know I have not included some header file, May I know which one is to include?

DEGREE is macro, not a method!!!

As you can easily guess by its name. Naming conventions come into play

You have to define it might be as :

#define DEGREES_TO_RADIANS(angle) ((angle) / 180.0 * M_PI)

or

#define DEGREE(angle) ((angle) / 180.0 * M_PI)
