Question

Inside drawRect, I drew few dashed lines after setting the dash pattern etc.
Now once I stroke this path I need to draw normal lines, what should I do ?

Answer 1

Sets the pattern for dashed lines in a graphics context.

void CGContextSetLineDash (
   CGContextRef c,
   CGFloat phase,
   const CGFloat lengths[],
   size_t count
);

Parameters
…

lengths

An array of values that specify the lengths of the painted segments and unpainted segments, respectively, of the dash pattern—or NULL for no dash pattern.

For example, passing an array with the values [2,3] sets a dash pattern that alternates between a 2-user-space-unit-long painted segment and a 3-user-space-unit-long unpainted segment. Passing the values [1,3,4,2] sets the pattern to a 1-unit painted segment, a 3-unit unpainted segment, a 4-unit painted segment, and a 2-unit unpainted segment.
