ios 4中的tabbar自定义 [英] Tabbar customization in ios 4

问题描述

我正在开发iOS应用程序，我需要将tabbar自定义如下：

I'm working on an iOS application and I need to customize the tabbar to be like this:

Tabbar Image

网络搜索给了我这个解决方案：

A web search gave me this solution:

[self.tabBarItem setFinishedSelectedImage:<#(UIImage *)#> withFinishedUnselectedImage:<#(UIImage *)#>]

但它适用于iOS5。有没有适用于iOS4和iOS5的解决方案？

But it is for iOS5. Is there a solution that works in both iOS4 and iOS5?

推荐答案

//这是我成功实施的代码... ....

//here is the code that i implement successfully.......

//在.h中设置委托UITabBarControllerDelegate，UITabBarDelegate

//in .h set delegate UITabBarControllerDelegate,UITabBarDelegate

    UINavigationController *navigationController;
    UITabBarController *tabBarController;
    @property(strong,nonatomic) UINavigationController *navigationController;
    @property(strong,nonatomic) UITabBarController *tabBarController;

// in .m

  tabBarController = [[UITabBarController alloc] init];
  [tabBarController setDelegate: self];

//用于标签栏背景
tabBarController.tabBar.tintColor = [UIColor colorWithPatternImage：[UIImage] imageNamed：@tabbg.png]];

//for tabbar background tabBarController.tabBar.tintColor=[UIColor colorWithPatternImage:[UIImage imageNamed:@"tabbg.png"]];

NSMutableArray * localViewControllersArray = [[NSMutableArray alloc] initWithCapacity：4];

NSMutableArray *localViewControllersArray = [[NSMutableArray alloc] initWithCapacity:4];

Demo1 *home = [[Login alloc] initWithNibName:@"Login" bundle:nil];
    localNavController = [[UINavigationController alloc] initWithRootViewController:home];
localNavController.tabBarItem.title=@"demo1";
[localViewControllersArray addObject:localNavController];
    Demo2 *puck=[[Demo2 alloc]initWithNibName:@"Demo2" bundle:nil];
    localNavController = [[UINavigationController alloc] initWithRootViewController:puck];
localNavController.tabBarItem.title=@"demo2";
[localViewControllersArray addObject:localNavController];
    Demo3 *photo=[[Demo3 alloc]initWithNibName:@"Demo3" bundle:nil];
    localNavController = [[UINavigationController alloc] initWithRootViewController:photo];
localNavController.tabBarItem.title=@"demo3";
    [localViewControllersArray addObject:localNavController];
    Demo4 *more=[[Demo4 alloc]initWithNibName:@"Demo4" bundle:nil];
    localNavController = [[UINavigationController alloc] initWithRootViewController:more];
localNavController.tabBarItem.title=@"demo4";
[localViewControllersArray addObject:localNavController];

  [[UITabBarItem appearance] setTitleTextAttributes:
 [NSDictionary dictionaryWithObjectsAndKeys:
  [UIColor grayColor], UITextAttributeTextColor, 
  [UIColor grayColor], UITextAttributeTextShadowColor, 
  [NSValue valueWithUIOffset:UIOffsetMake(0, 1)], UITextAttributeTextShadowOffset, 
  [UIFont fontWithName:@"Helvetica" size:0.0], UITextAttributeFont, 
  nil] 
                                         forState:UIControlStateNormal];

//标签栏选中和未选中的图标

//tab bar selected and unselected icons

UITabBarItem *tabBarItem1 = [[self.tabBarController.tabBar items] objectAtIndex:0];
[tabBarItem1 setFinishedSelectedImage:[UIImage imageNamed:@"puckCentralA.png"] withFinishedUnselectedImage:[UIImage imageNamed:@"puckCentral.png"]];
UITabBarItem *tabBarItem2 = [[self.tabBarController.tabBar items] objectAtIndex:1];
[tabBarItem2 setFinishedSelectedImage:[UIImage imageNamed:@"puckDisplayA.png"] withFinishedUnselectedImage:[UIImage imageNamed:@"puckDisplay.png"]];
UITabBarItem *tabBarItem3 = [[self.tabBarController.tabBar items] objectAtIndex:2];
[tabBarItem3 setFinishedSelectedImage:[UIImage imageNamed:@"photoBoothA.png"] withFinishedUnselectedImage:[UIImage imageNamed:@"photoBooth.png"]];
UITabBarItem *tabBarItem4 = [[self.tabBarController.tabBar items] objectAtIndex:3];
[tabBarItem4 setFinishedSelectedImage:[UIImage imageNamed:@"moreA.png"] withFinishedUnselectedImage:[UIImage imageNamed:@"more.png"]];

[self.window addSubview：tabBarController.view];

[self.window addSubview:tabBarController.view];
