导航栏iPhone中横向模式下的iOS UISearchBar高度

Question

我需要横向模式下的searchBar帮助。 我将其添加到导航栏titleView-居中：

self.searchBarTop = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, 80, 30)];
self.navigationItem.titleView = self.searchBarTop;

在横向模式下，合适的尺寸要大一些：

有什么建议么？

使用以下代码查找iphone的方向，然后相应地设置SearchBar的框架。在ViewDidLoad中设置SearchBar的框架（纵向模式）。

- (void)viewDidLoad {
    [super viewDidLoad];
    UISearchBar *searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(-5.0, 0.0, 320.0, 44.0)];
    UIView *searchBarView = [[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, 310.0, 44.0)];
    searchBar.delegate = self;
    [searchBarView addSubview:searchBar];
    self.navigationItem.titleView = searchBarView;
}

-(void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation) interfaceOrientation duration:(NSTimeInterval)duration {
    if (interfaceOrientation == UIInterfaceOrientationPortrait || interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown) {     

        UISearchBar *searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(-5.0, 0.0, 320.0, 44.0)];
        UIView *searchBarView = [[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, 310.0, 44.0)];
        searchBar.delegate = self;
        [searchBarView addSubview:searchBar];
        self.navigationItem.titleView = searchBarView;
    }
    else
    {
        UISearchBar *searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(-5.0, 0.0, 480.0, 44.0)];
        UIView *searchBarView = [[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, 470.0, 44.0)];
         searchBar.delegate = self;
        [searchBarView addSubview:searchBar];
        self.navigationItem.titleView = searchBarView;

    }
}

它一定会为您提供帮助。

显然，这是自定义UISearchBar的灰色区域。 我设法使用另一种方法将searchBar移到navigationBar之外。
