How to programmatically rotate image by 90 Degrees in iPhone?

Answer 1

//create rect UIImageView *myImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"my_image.png"]];  //set point of rotation myImageView.center = CGPointMake(100.0, 100.0);  //rotate rect myImageView.transform = CGAffineTransformMakeRotation(M_PI_2); //rotation in radians 

Answer 2

see this:

 myImage.center = CGPointMake(0, 0);  myImage.transform = CGAffineTransformMakeRotation([degreesToRadians:imageRotationFix]);
