我正在ios应用程序中工作，我需要自定义tabbar为这样
首先，我viewcontrollers在导航控制器中创建了 5 个，然后将它们放入tabbbarcontroller
我用谷歌搜索了这个问题，我找到了解决方案
[self.tabBarItem setFinishedSelectedImage:<#(UIImage *)#> withFinishedUnselectedImage:<#(UIImage *)#>]
但它适用于 iOS 5，我需要适用于 iOS 4 和 iOS 5 的解决方案。
对于在 ios4 中自定义选项卡栏，您需要为我们制作自定义选项卡栏的代码不可用，您可以参考此 Que。
或者你也可以像这样制作完整的标签栏图像来做简单的逻辑
在这里，我在 appdel did finish 方法上制作了一个图像视图，并在应用程序中完成了这样的操作。
self.imgV.frame=CGRectMake(0, 431, 320, 49);
[self.tabbarcontroller.view addSubview:self.imgV];
- (BOOL)tabBarController:(UITabBarController *)tabBarController shouldSelectViewController:(UIViewController *)viewController{
NSUInteger index=[[tabBarController viewControllers] indexOfObject:viewController];
NSString *deviceType = [UIDevice currentDevice].model;
NSLog(@"Device%@",deviceType);
if(UI_USER_INTERFACE_IDIOM()==UIUserInterfaceIdiomPad){
// self.imgV.frame=CGRectMake(0, 975, 768, 49);
//[self.tabbarcontroller.view addSubview:self.imgV];
switch (index) {
case 0:
self.imgV.image=[UIImage imageNamed:@"reservation_tab~iPad.png"];
break;
case 1:
self.imgV.image=[UIImage imageNamed:@"place_order_tab~iPad.png"];
break;
case 2:
self.imgV.image=[UIImage imageNamed:@"location_tab~iPad.png"];
break;
case 3:
self.imgV.image=[UIImage imageNamed:@"favorite_tab~iPad.png"];
break;
case 4:
self.imgV.image=[UIImage imageNamed:@"signature_dishes_tab~iPad.png"];
break;
case 5:
self.imgV.image=[UIImage imageNamed:@"history_tab~iPad.png"];
break;
case 6:
self.imgV.image=[UIImage imageNamed:@"contact_us_tab~iPad.png"];
break;
default:
break;
}
}
else{
switch (index) {
case 0:
self.imgV.image=[UIImage imageNamed:@"reservation_tab.png"];
break;
case 1:
self.imgV.image=[UIImage imageNamed:@"place_order_tab.png"];
break;
case 2:
self.imgV.image=[UIImage imageNamed:@"location_tab.png"];
break;
case 3:
self.imgV.image=[UIImage imageNamed:@"favorite_tab.png"];
break;
case 4:
self.imgV.image=[UIImage imageNamed:@"gallery_tab.png"];
break;
default:
break;
}
}
return YES;
}
试试这个粘贴它.h文件
#import <UIKit/UIKit.h>

我已经使用此代码对我来说很好。
在AppDelegate.m文件中，添加以下代码。在那段代码中，我们创建了四个视图并将它们添加到选项卡控制器中。这些视图现在是空的，因为对于这个项目，我们不需要其中的任何内容。
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
UITabBarController *tabController = [[UITabBarController alloc] init];
UIViewController *viewController1 = [[UIViewController alloc] init];
UIViewController *viewController2 = [[UIViewController alloc] init];
UIViewController *viewController3 = [[UIViewController alloc] init];
UIViewController *viewController4 = [[UIViewController alloc] init];
tabController.viewControllers = [NSArray arrayWithObjects:viewController1,
viewController2,
viewController3,
viewController4, nil];
self.window.rootViewController = tabController;
[self.window makeKeyAndVisible];
return YES;
}
