Randomize Rotation with CGAffineTransformMakeRotation

[sirvin]

I am trying to make an arrow spin using CGAffineTransformMakeRotation and it works if I hard code a number, but when i try passing it a variable, it gives the error: "error: incompatible type for argument 1 of 'CGAffineTransformMakeRotation'". I thought the data type it took was CGFloat but that doesn't work. How do I fix this?

CGFloat *angle = random() % 100;
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[arrow setTransform:CGAffineTransformMakeRotation (angle)];
[UIView commitAnimations];

the angle should be in radians, probably between 0 and 2 PI

edit: Also you change CGFloat* to just CGFloat

OMG! Thank you, it works now. All I had to do was take out the asterisk!
