我正在用UINavigation控制器在xCode 4.3.2中創建一個tabBar應用程序。我在AppDelegate中使用下面的代碼Xcode 4.3.2 UINavigationBar圖像背景
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
// Override point for customization after application launch.
UIViewController *viewController1 = [[[FirstViewController alloc] initWithNibName:@"FirstViewController" bundle:nil] autorelease];
UIViewController *viewController2 = [[[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle:nil] autorelease];
self.tabBarController = [[[UITabBarController alloc] init] autorelease];
self.tabBarController.viewControllers = [NSArray arrayWithObjects:
[[[UINavigationController alloc] initWithRootViewController:viewController1] autorelease], viewController2, nil];
self.window.rootViewController = self.tabBarController;
[self.window makeKeyAndVisible];
return YES;
}
現在的問題是,我想要在導航欄中的自定義背景圖像。我發現的解決方案是編寫UINavigationBar的子類,並在界面構建器中設置新的子類。但在我的情況下,我設置導航控制器編程,然後如何實現這一目標? 我也嘗試創建類別爲
@implementation UINavigationBar (CustomImage)
- (void)drawRect:(CGRect)rect {
UIImage *image = [UIImage imageNamed:@"NavigationBar.png"];
[image drawInRect:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height)];
}
@end
但它並沒有工作。
你想設置的TabBar或導航欄的背景圖像。你的問題標題是相關的導航欄,你張貼代碼爲tabbar? –
Mitesh Khatri,我想設置navigationBar的背景圖片,我發佈了代碼以顯示我如何添加導航控制器。我試圖subclass navigationBar,但我不知道如何設置navigatioBar類到我的新子類,因爲我正在做所有的編程。 Thanx等待你的回覆 –
