I'm using this code to rotate image :
if([(UIRotationGestureRecognizer*)sender state] == UIGestureRecognizerStateEnded)
{
currentrotation += lastRotation;
lastRotation = 0.0;
return;
}
CGFloat rotation = 0.0 - (lastRotation - [(UIRotationGestureRecognizer*)sender rotation]);
CGAffineTransform currentTransform = imgComment.transform;
CGAffineTransform newTransform = CGAffineTransformRotate(currentTransform,rotation);
[imgComment setTransform:newTransform];
lastRotation = [(UIRotationGestureRecognizer*)sender rotation];
Can't get position of image view when it rotates.
Now I want to get position of top-left side of the corner of ImageView when image rotates.
Please Help !!
You will need to get the coordinates of the individual corners by applying a transformation. The frame of the rooted view will be the smallest possible rectangle that encloses the view. To get the rotated coordinate of a point use:
CGPoint transformedPoint = CGPointApplyAffineTransform(originalCoordinate, transform);
The original coordinates are top-left, top-right, bottom-left and bottom-right of your initial frame rectangle.
