After the view has rotated you should be able to get the new dimensions of the view.
视图旋转后，您应该能够获得视图的新尺寸。
- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation {
CGRect myFrame = [self.view frame];
NSLog(@"height = %f", myFrame.size.height);
NSLog(@"width = %f", myFrame.size.width);
NSLog(@"x = %f", myFrame.origin.x);
NSLog(@"y = %f", myFrame.origin.y);
}

try this
尝试这个
- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation
{
float x = yourView.bounds.origin.x;
float y = yourView.bounds.origin.y;
float width = yourView.bounds.size.width;
float height = yourView.bounds.size.height;
NSLog(@"x=%f,y=%f,w=%f,h=%f",x,y,width,height);
}

after the rotation try.
轮换后试试。
NSLog(@"x = %.2f y = %.2f width = %.2f height = %.2f", view.frame.origin.x , view.frame.origin.y, view.frame.size.width, view.frame.size.height);

- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation
{
/*Subclasses may override this method to perform additional actions immediately after
the rotation. For example, you might use this method to reenable view interactions,
start media playback again, or turn on expensive drawing or live updates. By the time
this method is called, the interfaceOrientation property is already set to the new
orientation.*/
CGRect frame = self.view.frame
}
