iOS UISearchBar在導航條中的橫向模式下的高度iPhone

Question

我需要在橫向模式下使用searchBar的幫助。我將它添加到的導航欄titleview的 - 中心：

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

在橫向模式下它要大，超出了正常：

有什麼建議？

Answer 1

顯然這是定製UISearchBar的灰色區域。我設法使用另一種方式移動導航欄外的searchBar。

Answer 2

使用以下代碼來查找iphone的方向，然後設置相應的SearchBar框架。在ViewDidLoad中設置SearchBar（縱向模式）的框架。

- (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; 

    } 
} 

它一定會幫助你。
