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];
}
}
