Using a random point in two actions - cocos2d-iphone

Question

Sorry I'm new to this.
Right now I'm trying to create an endless randomly moving sprite that rotates to its direction. However I can't figure out how to use the random location generated from randomPoint on the rotateAction. Basically the bug randomly rotates instead of using the point it's going to. Is there a way I can use the same random point twice?
-(void)moveRandom:(CCSprite*)roach
{
CGPoint randomPoint = ccp(arc4random()%480, arc4random()%320);
NSLog(#"%#", NSStringFromCGPoint(randomPoint));
int minDuration = 2.0;
int maxDuration = 4.0;
int rangeDuration = maxDuration - minDuration;
int randomDuration = (arc4random() % rangeDuration) + minDuration;
float dY = roach.position.y - randomPoint.y;
float dX = roach.position.x - randomPoint.x;
float offset = dX<0 ? 90.0f : -90.0f;
float angle = CC_RADIANS_TO_DEGREES(atan2f(dY, dX)) + offset;
[roach runAction:
[CCActionSequence actions:
[CCActionRotateTo actionWithDuration:0.001 angle:angle],
[CCActionMoveTo actionWithDuration:randomDuration position: randomPoint],
[CCActionCallBlock actionWithBlock:^{
[self performSelector:#selector(moveRandom:) withObject:roach afterDelay:0.5];
}],
nil]
];

Some things that stand out: It looks like you're trying to get the angle in the wrong direction. The conditional offset is not needed. radians to degrees should be negated .. I'm guessing you want:
float dY = randomPoint.y - roach.position.y;
float dX = randomPoint.x - roach.position.x;
float angle = -CC_RADIANS_TO_DEGREES(atan2f(dY, dX));
