Hi David,
Thanks for the reply. When I remove the reference to
UIGraphicsGetCurrentContext() my Image doesn't drop in.
Removed:
CGContextRef context = UIGraphicsGetCurrentContext();
[UIView beginAnimations:@"moveImageDown" context:context];
The following code works:
imageView = [ [ UIImageView alloc ] initWithFrame:CGRectMake(295,
480/2, image.size.width, image.size.height) ];
imageView.image = image;
imageView.transform = CGAffineTransformMakeRotation(M_PI/2.0);
imageBottomView = [ [ UIImageView alloc ]
initWithFrame:CGRectMake(-220, 207, imageBottom.size.width,
imageBottom.size.height) ];
imageBottomView.image = imageBottom;
imageBottomView.transform = CGAffineTransformMakeRotation(M_PI/2.0);
pos = 295;
CGContextRef context = UIGraphicsGetCurrentContext();
[UIView beginAnimations:@"moveImageDown" context:context];
[UIView setAnimationDuration:2.0];
[imageView setCenter:CGPointMake(pos, 480 / 2 )];
[UIView commitAnimations];
[mpw addSubview:imageView];
Thoughts?
