UIScrollView Custom View rotation problem - objective-c

Question

I have a ScrollView with a Custom View. Now i have the problem with the rotation, the view has after the rotation not the correct frame pos / size.
How can i call the CustomView after rotation for a reposition and resize the frame and content?!
- (void)setupPage
{
NSUInteger nimages = 0;
CGFloat cx = 0;
for (; ; nimages++) {
if (nimages == list.count) {
break;
}
CustomStepView *stepView = [[CustomStepView alloc] initWithFrame:CGRectZero];
stepView.tag = nimages;
if([[UIDevice currentDevice] orientation] == UIDeviceOrientationPortrait || [[UIDevice currentDevice] orientation] == UIDeviceOrientationPortraitUpsideDown)
{
stepView.frame = CGRectMake(cx, 0.0 , 768.0f, 926.0f);
cx += 768.0;
}
else
{
stepView.frame = CGRectMake(cx, 0.0 , 1024.0f, 670.0f);
cx += 1024.0;
}
[scrollView addSubview:stepView];
[stepView release];
}
self.pageControl.numberOfPages = nimages;
}

From what it looks like, You have a lot of subviews(Custom Views) in your ScrollView.
First of all never try to detect the orientation using UIDevice , it is not recommended by apple.
For handling rotations you have been provided with the function : "shouldAutorotateToInterfaceOrientation"
Inside this method, You can simple run a loop for detecting the subviews present inside your scrollview and then set the frame and size of each subview.
This might look something like this:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
if(interfaceOrientation == UIInterfaceOrientationPortrait)
{
for(UIView *asubview in scrollView.subviews)
{
asubview.frame = "NEW FRAME";
}
}
else
{
asubview.frame = "NEW FRAME";
}
}
Hope it helps you..although i know this has been asked long back :-)
Cheers
