I am using tableview with search bar display controller, it shows good in portait and landscape view, but rotate from landscape to portrait search bar size is reduced, how to change the original size

推荐答案

第一个你应该抓住方向：

The first your should catch the orientation:

 //AppDelegate.h
 @interface AppDelegate : UIResponder <UIApplicationDelegate>
 @property (nonatomic, unsafe_unretained) NSInteger isPortrait;

//AppDelegate.m
@synthesize isPortrait;


- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{

   isPortrait = 1;

}

实施状态：

-(void)viewWillAppear:(BOOL)animated{

   [[UIApplication sharedApplication] statusBarOrientation];
   [[UIDevice currentDevice] orientation];
   [[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
   [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(deviceRotated:) name:UIDeviceOrientationDidChangeNotification object:nil];
}

 //methode deviceRotated 

-(void)deviceRotated:(NSNotification*)notification{

   AppDelegate *app = (AppDelegate *)[UIApplication sharedApplication].delegate;
   UIInterfaceOrientation orientation = [[UIApplication sharedApplication] statusBarOrientation];
   if(orientation == UIInterfaceOrientationLandscapeLeft || orientation == UIInterfaceOrientationLandscapeRight)
   {
      [self searchBarLandscape];
       app.isPortrait = NO;
  }
  else{
     [self searchBarPortrait];
     app.isPortrait = YES;
  }

}

- (BOOL) shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation{
    return YES;
}

- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{
    AppDelegate * app = (AppDelegate *)[UIApplication sharedApplication].delegate;
   if (toInterfaceOrientation == UIInterfaceOrientationPortraitUpsideDown || toInterfaceOrientation == UIInterfaceOrientationPortrait) 
   {
    app.isPortrait = 1;
   }
  else if (toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft || toInterfaceOrientation == UIInterfaceOrientationLandscapeRight)
  {
    app.isPortrait = 0;
  }
  [self prepareSearchBarOrientation];

}


-(void)prepareSearchBarOrientation
{

   AppDelegate * app = (AppDelegate *)[UIApplication sharedApplication].delegate;
   if (app.isPortrait)
   {
       [self searchBarPortrait];//Set Frame here
   }
  else
  {
      [self searchBarLandscape];

  }

}
