UIImageView rotation (NOT the image, but the view)

Question

How do I rotate the ImageView ... i'm trying to use landscape mode, and have a problem with accelerometer moving the image ... Because when I work in portrait mode the x of accelerometer is the same as the x of the image ... But when I work landscape, the x of accelerometer is the y of the image, because the ImageView autorotates with the parent View. When I rotate the image with CGAffineTransformMakeRotation(M_PI/2), it rotates only the image in it's ImageView... and the x,y sides stays untouched ... Is there any way to make own class which will extend UIImageView where I will swap the x,y sides of a UIImageView ? Or is there some way to rotate the UIImageView, and not only the image in it?

Answer 1

float degree = atan2(accelX, accelY) * 180 / 3.14159;

其中accelX和accelY是来自加速度计的值，请使用度数并旋转ImageView。

Answer 2

Try to convert points depending on orientation...

if( orientation == LANDSCAPE )
{

   CGPoint temp;

  temp = [touch locationInView:self];

  touchPoint.x = temp.y;

  touchPoint.y = 320 - temp.x;

}

The above code convert points from portrait to landscape...
