Orientating app's view to landscape and portrait - ios

Question

I've UIViewController and another UIView with some images and labels on it.
I wanna change orientation and it works well, I can change aqGridview frame when rotating device,
My code :
- (void)makePortraitOrientation {
[gridView setFrame:CGRectMake(0, 43, 768,961)]; //works like a charm
HeaderView* dsd = [[HeaderView alloc] initWithParentID:self]; // in this way there is no errors but nothing changes
[dsd.label setFrame:CGRectMake(0, 0, 0, 0)];
[dsd setNeedsDisplay];
[self.HeaderView.label setFrame:CGRectMake(0, 0, 0, 0)]; //error, no object HeaderView in UIViewController
[self.HeaderView.label CGRectMake]
}
Header file of UIView
#interface HeaderView : UIView{
id parentID;
UIButton *menu;
UIImageView *icon;
NSString *product;
THLabel *label;
NSMutableArray *backs;
}
The main problem is how can i change frames and places of images and
labels which is on another UIView, not in my UIViewController ?
All the views created programatically.

Answer 1

Based on your controls frame you need to adjust the position of our controls while rotating the device.
Access controls which is in our view controller like this. [self.button setFrame:];
Access the sub view controls frame like this: [self.subviewname.control setFrame:];
Based on the orientation you need to handle the frames. You can use auto re-sizing also.
Update:
Make sure whether your sub view is added properly in your view controller like this :
[self.view addSubView:self.mysubView];
Increase the score of your sub view(HeaderView) as well.
