RDVTabBarController这个库写得相当不错，所以今天就简单介绍下它的基本使用，看里面可以清楚的知道代码规范的重要性，这个库的使用方法和官方的相识
下载地址：https://github.com/robbdimitrov/RDVTabBarController
首先写过控制器继承 RDVTabBarController，
AppDelegate里面的不多说
例如
1 self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
2
3 RDVViewController *rootViewController = [[RDVViewController alloc] init];
4 self.window.rootViewController = rootViewController;
5 [self.window makeKeyAndVisible];
然后在
RDVViewController.m文件里
为了防止tabbar的双点击事件，设置代理<RDVTabBarControllerDelegate>,添加标示，用在点击事件
要设置tabbaritem的字体和图片，需导入文件
#import "RDVTabBarItem.h"
1 #import "RDVViewController.h"
2 #import "ViewController.h"
3 #import "RDVTabBarItem.h"
4
5 @interface RDVViewController ()<RDVTabBarControllerDelegate>
6 {
7 NSInteger selectedTabBarIiemTag;
8 }
9 @end
10
11 @implementation RDVViewController
12
13 - (void)viewDidLoad {
14 [super viewDidLoad];
15
16 ViewController *homeView=[[ViewController alloc]init];
17 UINavigationController *NAV1 = [[UINavigationController alloc] initWithRootViewController:homeView];
18
19 ViewController *View=[[ViewController alloc]init];
20 UINavigationController *NAV2 = [[UINavigationController alloc] initWithRootViewController:View];
21
22 ViewController *home=[[ViewController alloc]init];
23 UINavigationController *NAV3 = [[UINavigationController alloc] initWithRootViewController:home];
24
25 self.viewControllers = @[NAV1,NAV2,NAV3];
26 [self customizeTabBarForController:self];
27 self.delegate = self;
28 }
29
30 - (void)customizeTabBarForController:(RDVTabBarController *)tabBarController {
31
32 NSArray *tabBarItemImages = @[@"首页select", @"首页select",@"首页select"];
33
34 NSInteger index = 0;
35 for (RDVTabBarItem *tabberItem in [[tabBarController tabBar] items]) {
36
37 tabberItem.title = [NSString stringWithFormat:@"%ld",index+1];
38
39 NSDictionary *tabBarTitleUnselectedDic = @{NSForegroundColorAttributeName:[UIColor blackColor],NSFontAttributeName:[UIFont systemFontOfSize:15]};
40 NSDictionary *tabBarTitleSelectedDic = @{NSForegroundColorAttributeName:[UIColor blueColor],NSFontAttributeName:[UIFont systemFontOfSize:15]};
41 //修改tabberItem的title颜色
42 tabberItem.selectedTitleAttributes = tabBarTitleSelectedDic;
43 tabberItem.unselectedTitleAttributes = tabBarTitleUnselectedDic;
44 tabberItem.tag = 100+index;
45 UIImage *selectedimage = [UIImage imageNamed:@"首页"];
46 UIImage *unselectedimage = [UIImage imageNamed:[NSString stringWithFormat:@"%@",
47 [tabBarItemImages objectAtIndex:index]]];
48 //设置tabberItem的选中和未选中图片
49 [tabberItem setFinishedSelectedImage:selectedimage withFinishedUnselectedImage:unselectedimage];
50
51 index++;
52 }
53 }
上面就满足基本使用方法了，为了防止双点击事件，已经设置了代理和tag值
这里的item不是tabbaritem,而是 rdv_tabBarItem,如果使用了tabBarItem的tag值，那是不存在的，因为这里设置的是rdv的tabBarItem
1 #pragma mark - 防止tabbar双击
2 - (BOOL)tabBarController:(UITabBarController *)tabBarController shouldSelectViewController:(UIViewController *)viewController {

4 if(selectedTabBarIiemTag == viewController.rdv_tabBarIte
