ios - CGPath animation with Facebook POP engine -


i have been using facebook pop engine (https://github.com/facebook/pop) great results since launched earlier year.

until haven't needed implement animation on custom properties, have situation animate cashapelayer cgpath property (which isn't 1 of standard properties).

this suggested method...

prop = [popanimatableproperty propertywithname:@"com.foo.radio.volume" initializer:^(popmutableanimatableproperty *prop) {  // read value prop.readblock = ^(cashapelayer *obj, cgfloat values[]) {   values[0] = [obj volume]; };  // write value prop.writeblock = ^(cashapelayer *obj, const cgfloat values[]) {   [obj setvolume:values[0]]; };  // dynamics threshold prop.threshold = 0.01;  }];  anim.property = prop;

but can't work out apply cgpath property.

any suggestions received.
