Step1：宣告一個監聽事件，監聽UIDeviceOrientationDidChangeNotification方向轉換
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(orientationChanged:)
name:UIDeviceOrientationDidChangeNotification
object:nil];
Step2：撰寫function orientationChanged，針對不同規格刻版面。

CGFloat img_x=0.0f,img_y=65.0f,img_width=320.0f,img_height=40.0f;
CGFloat Seg_x=10.0f,Seg_y=70.0f,Seg_width=300.0f,Seg_height=30.0f;
UIDeviceOrientation deviceOrientation = [UIDevice currentDevice].orientation;
if ( UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad ){
NSLog(@"ipad");if (UIDeviceOrientationIsLandscape(deviceOrientation))

NSLog(@"iphone");if (UIDeviceOrientationIsLandscape(deviceOrientation))

imageView.frame=CGRectMake(img_x,img_y,img_width,img_height);
mySegmentedControl.frame=CGRectMake(Seg_x,Seg_y,Seg_width,Seg_height);
}
}
另外一種做法，可以說是比較懶惰的做法，只要刻一個版面就好，可以針對不同需求來作設定。
我想大家都應該知道ios6以上針對版面的轉換，已經更新了函式，現在是
- (BOOL)shouldAutorotate
{
//returns true if want to allow orientation change
return NO;
}- (NSUInteger)supportedInterfaceOrientations
{
//decide number of origination tob supported by Viewcontroller.
return UIInterfaceOrientationMaskAll;
}- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
//from here you Should try to Preferred orientation for ViewController
return UIInterfaceOrientationPortrait;
}但是呢？如果你用stroyboard來做版面的時候，會發現，似乎沒辦法針對每個版面進行不同的設定，例如你要再navigation controller 將 portrait 轉成 landscape，這個意思是第一個版面是portrait，第二個頁面是landscape，這樣就會遇到了困難，這樣怎麼解決呢？
Step1：在AppDelegate內的@end後加入下面程式碼
@implementation UINavigationController (Rotation_IOS6)
{
//NSLog(@"shouldAutorotate");
return [[self.viewControllers lastObject] shouldAutorotate];
}{
//NSLog(@"supportedInterfaceOrientations");
return [[self.viewControllers lastObject] supportedInterfaceOrientations];
}{
//NSLog(@"preferredInterfaceOrientationForPresentation");
return [[self.viewControllers lastObject] preferredInterfaceOrientationForPresentation];
}
@end
Step2：在你要的頁面中加入上述的函式即可
- (BOOL)shouldAutorotate
{
//returns true if want to allow orientation change
return NO;
}
- (NSUInteger)supportedInterfaceOrientations
{
//decide number of origination tob supported by Viewcontroller.
return UIInterfaceOrientationMaskAll;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
//from here you Should try to Preferred orientation for ViewController
return UIInterfaceOrientationPortrait;
}
