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

 self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

 RDVViewController *rootViewController = [[RDVViewController alloc] init];
 self.window.rootViewController = rootViewController;
 [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"

 #import "RDVViewController.h"
 #import "ViewController.h"
 #import "RDVTabBarItem.h"

 @interface RDVViewController ()<RDVTabBarControllerDelegate>
 {
     NSInteger selectedTabBarIiemTag;
 }
 @end

 @implementation RDVViewController

 - (void)viewDidLoad {
     [super viewDidLoad];

     ViewController *homeView=[[ViewController alloc]init];
     UINavigationController *NAV1 = [[UINavigationController alloc] initWithRootViewController:homeView];

     ViewController *View=[[ViewController alloc]init];
     UINavigationController *NAV2 = [[UINavigationController alloc] initWithRootViewController:View];

     ViewController *home=[[ViewController alloc]init];
     UINavigationController *NAV3 = [[UINavigationController alloc] initWithRootViewController:home];

     self.viewControllers = @[NAV1,NAV2,NAV3];
     [self customizeTabBarForController:self];
     self.delegate = self;
 }

 - (void)customizeTabBarForController:(RDVTabBarController *)tabBarController {

     NSArray *tabBarItemImages = @[@"首页select", @"首页select",@"首页select"];

     NSInteger index = ;
     for (RDVTabBarItem *tabberItem in [[tabBarController tabBar] items]) {

         tabberItem.title = [NSString stringWithFormat:@"%ld",index+];

         NSDictionary *tabBarTitleUnselectedDic = @{NSForegroundColorAttributeName:[UIColor blackColor],NSFontAttributeName:[UIFont systemFontOfSize:]};
         NSDictionary *tabBarTitleSelectedDic = @{NSForegroundColorAttributeName:[UIColor blueColor],NSFontAttributeName:[UIFont systemFontOfSize:]};
         //修改tabberItem的title颜色
         tabberItem.selectedTitleAttributes = tabBarTitleSelectedDic;
         tabberItem.unselectedTitleAttributes = tabBarTitleUnselectedDic;
         tabberItem.tag = +index;
         UIImage *selectedimage = [UIImage imageNamed:@"首页"];
         UIImage *unselectedimage = [UIImage imageNamed:[NSString stringWithFormat:@"%@",
                                                         [tabBarItemImages objectAtIndex:index]]];
         //设置tabberItem的选中和未选中图片
         [tabberItem setFinishedSelectedImage:selectedimage withFinishedUnselectedImage:unselectedimage];

         index++;
     }
 }

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

 #pragma mark - 防止tabbar双击
 - (BOOL)tabBarController:(UITabBarController *)tabBarController shouldSelectViewController:(UIViewController *)viewController {

     if(selectedTabBarIiemTag == viewController.rdv_tabBarItem.tag){

         return NO;

     }else {

         selectedTabBarIiemTag = viewController.rdv_tabBarItem.tag;
         return YES;

     }
 }
