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 = 0;
    for (RDVTabBarItem *tabberItem in [[tabBarController tabBar] items]) {
        
        tabberItem.title = [NSString stringWithFormat:@"%ld",index+1];
        
        NSDictionary *tabBarTitleUnselectedDic = @{NSForegroundColorAttributeName:[UIColor blackColor],NSFontAttributeName:[UIFont systemFontOfSize:15]};
        NSDictionary *tabBarTitleSelectedDic = @{NSForegroundColorAttributeName:[UIColor blueColor],NSFontAttributeName:[UIFont systemFontOfSize:15]};
        //修改tabberItem的title颜色
        tabberItem.selectedTitleAttributes = tabBarTitleSelectedDic;
        tabberItem.unselectedTitleAttributes = tabBarTitleUnselectedDic;
        tabberItem.tag = 100+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;
        
    }
}
