iOS how to rotate uiimageview at certain angle?

[rahulvyas]

Hello all,
i am new to iphone development.
i am creating a game in which we have to hold a cup(UIimageview) while holding when i move my finger to right then rotate cup slightly to left and if i move finger left rotate cup to right.So what is the best possible way to do this.I have tried UIView animation but it's very fast.ALso how do i pass angel of rotation?

you can control the animation block duration with setAnimationDuration:

[UIView setAnimationDuration:kSpeedInSecondsOfAnimation];

use CGAffineTransformMakeRotation to rotate your image object. it rotates in radians, so i've included a macro that will allow you to enter a degree.

#define kDegreesToRadians(x) (M_PI * (x) / 180)

CGAffineTransform transform = CGAffineTransformMakeRotation(kDegreesToRadians([I]angel[/I]));
yourView.transform = transform;
