RDVTabBarController的基本使用 以及tabbar的防止双点击方法

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 {
 3
 4     if(selectedTabBarIiemTag == viewController.rdv_tabBarItem.tag){
 5
 6         return NO;
 7
 8     }else {
 9
10         selectedTabBarIiemTag = viewController.rdv_tabBarItem.tag;
11         return YES;
12
13     }
14 }
