我实施了UITabBarController4 个项目。
我ViewController从AppDelegate.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
HomeTabBarViewController* homeVC = [[HomeTabBarViewController alloc] init];
[self.window setRootViewController:homeVC];
[self.window makeKeyAndVisible];
return YES;
}
这是 HomeTabBarViewController ViewDidLoad代码：
UIViewController *view1 = [[UIViewController alloc] init];
[view1.view setBackgroundColor:[UIColor redColor]];
UIViewController *view2 = [[UIViewController alloc] init];
UINavigationController * centerNav=[[UINavigationController alloc]initWithRootViewController:view1];
HomePagingViewController * view3=(HomePagingViewController*)[storyboard instantiateViewControllerWithIdentifier:@"HomePagingViewController"];
UINavigationController * centerNav3=[[UINavigationController alloc]initWithRootViewController:view3];
UIViewController *view4 = [[UIViewController alloc] init];
UINavigationController * centerNav4=[[UINavigationController alloc]initWithRootViewController:view4];
[view2.view setBackgroundColor:[UIColor greenColor]];
[view3.view setBackgroundColor:[UIColor purpleColor]];
[view4.view setBackgroundColor:[UIColor grayColor]];
NSMutableArray *tabViewControllers = [[NSMutableArray alloc] init];
[tabViewControllers addObject:centerNav];
[tabViewControllers addObject:view2];
[tabViewControllers addObject:centerNav3];
[tabViewControllers addObject:centerNav4];
[self setViewControllers:tabViewControllers];
view1.tabBarItem = [[UITabBarItem alloc] initWithTitle:@"Home"
image:[UIImage imageNamed:@"home_tab_item.png"] selectedImage:[UIImage imageNamed:@"home_tab_item_active.png"]] ;
view2.tabBarItem =
[[UITabBarItem alloc] initWithTitle:@"Bookmark"
image:[UIImage imageNamed:@"bookmark_tab_item.png"] selectedImage:[UIImage imageNamed:@"bookmark_tab_item_active.png"]];
view3.tabBarItem =
[[UITabBarItem alloc] initWithTitle:@"Paper"
image:[UIImage imageNamed:@"paper_tab_item.png"] selectedImage:[UIImage imageNamed:@"paper_tab_item_active.png"]];
view4.tabBarItem =
[[UITabBarItem alloc] initWithTitle:@"More"
image:[UIImage imageNamed:@"menu_tab_item.png"] selectedImage:[UIImage imageNamed:@"menu_tab_item_active.png"]];
在HomePagingViewController ViewDidLoad我在代码中设置导航
-(void)navigationSetUp{
self.navigationController.navigationBar.translucent=NO;
UIBarButtonItem * settingBtn=[[UIBarButtonItem alloc]initWithImage:[UIImage imageNamed:@"settings.png"] style:UIBarButtonItemStylePlain target:self action:@selector(menuHandler:)];
UIBarButtonItem * searchBtn=[[UIBarButtonItem alloc]initWithImage:[UIImage imageNamed:@"settings.png"] style:UIBarButtonItemStylePlain target:self action:@selector(menuHandler:)];
self.navigationItem.leftBarButtonItem = settingBtn;
self.navigationItem.rightBarButtonItem = searchBtn;
self.navigationItem.titleView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"ie_New_logo.png"]];
}
在此之后，当我更改HomePagingViewController导航右侧按钮的选项卡时未正确放置时，右侧没有边距。

请帮忙。
