RDVTabBarController的基本使用 以及tabbar的防止雙點擊方法

RDVTabBarController這個庫寫得相當不錯，所以今天就簡單介紹下它的基本使用，看裡面可以清楚的知道代碼規範的重要性，這個庫的使用方法和官方的相識

首先寫過控制器繼承　　RDVTabBarController，

AppDelegate裡面的不多說

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];

然後在

RDVViewController.m文件里

為了防止tabbar的雙點擊事件，設置代理<RDVTabBarControllerDelegate>,添加標示，用在點擊事件

要設置tabbaritem的字體和圖片，需導入文件

#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 = @[@"首頁select", @"首頁select",@"首頁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顏色
42         tabberItem.selectedTitleAttributes = tabBarTitleSelectedDic;
43         tabberItem.unselectedTitleAttributes = tabBarTitleUnselectedDic;
44         tabberItem.tag = 100+index;
45         UIImage *selectedimage = [UIImage imageNamed:@"首頁"];
46         UIImage *unselectedimage = [UIImage imageNamed:[NSString stringWithFormat:@"%@",
47                                                         [tabBarItemImages objectAtIndex:index]]];
48         //設置tabberItem的選中和未選中圖片
49         [tabberItem setFinishedSelectedImage:selectedimage withFinishedUnselectedImage:unselectedimage];
50         
51         index++;
52     }
53 }

上面就滿足基本使用方法了，為了防止雙點擊事件，已經設置了代理和tag值

這裡的item不是tabbaritem,而是  rdv_tabBarItem,如果使用了tabBarItem的tag值，那是不存在的，因為這裡設置的是rdv的tabBarItem

 1 #pragma mark - 防止tabbar雙擊
 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 }
