CGMutablePathRef to NSMutableArray

Question

How to add CGMutablePathRef to NSMutableArray?

Answer 1

You can wrap CGMutablePathRef to a NSValue and store it in array. Then when needed unwrap it:

//Wrap
NSValue *pathValue = [NSValue valueWithPointer: path];
[array addObject:pathValue];

//Unwrap
NSValue *pathValue = [array objectAtIndex: index];
CGMutablePathRef path = [pathValue pointerValue];

Note that valueWithPointer: method does not affect object's retain count so you must not release your path when adding to array (release it later when it is not needed anymore)

Answer 2

CGMutablePath path = <... your path ...>;
[mutableArray addObject:(id)path];

CGPath and CGMutablePath are just opaque CFType object types, and those can be added (via casting to id) to any Cocoa container classes that are toll-free bridged to their CoreFoundation counter-parts.
