RDVTabBarController:一个十分完善的tabBarController,可以自定义角标个数,爽的停不下来。
RDVTabBarController地址:RDVTabBarController

说明
此教程是旨在让你快速入手,如需更加深层次的了解,请直接RDVTabBarController地址分析即可;
使用
pod 'RDVTabBarController'
建议直接CocoaPods管理,对CocoaPods有兴趣的童鞋可以戳cocoapods-install-usage
结构
RDVTabBar
@interface RDVTabBar : UIView
RDVTabBarController
@interface RDVTabBarController : UIViewController
RDVTabBarItem
@interface RDVTabBarItem : UIControl
RDVTabBarController Example Usage其实已经很详细了,接下来看初始化
//VString宏定义,为了就是更好的国际化语言,适配多语言,刚好此Demo也国际化了,可以参看https://github.com/sauchye/dev_notes/issues/4 ?
#define VString(x) NSLocalizedString(x, nil)
- (void)setupViewControllers{
SYFirstViewController *firstVC = [[SYFirstViewController alloc] init];
SYSecondViewController *secondVC = [[SYSecondViewController alloc] init];
SYThirdViewController *thirdVC = [[SYThirdViewController alloc] init];
firstVC.title = VString(@"Home");
secondVC.title = VString(@"Found");
thirdVC.title = VString(@"Me");
self.firstNav = [[SYBaseNavigationController alloc] initWithRootViewController:firstVC];
self.secondNav = [[SYBaseNavigationController alloc] initWithRootViewController:secondVC];
self.thirdNav = [[SYBaseNavigationController alloc] initWithRootViewController:thirdVC];
[self setViewControllers:@[self.firstNav, self.secondNav, self.thirdNav]];
[self customizeTabBarForController];
}
- (void)customizeTabBarForController{
//tabbar 背景图片 tabbar_background
UIImage *backgroundImage = [UIImage imageNamed:@"tabbar_background"];
//选项卡图片
NSArray *tabBarItemImages;
//这里添加tabBar icon图片
//= @[VString(@"First"), VString(@"Second"),VString(@"Third")];
NSArray *tabBarItemTitles = @[VString(@"Home"), VString(@"Found"), VString(@"Me")];
NSInteger index = 0;
for (RDVTabBarItem *item in [[self tabBar] items])
{
item.titlePositionAdjustment = UIOffsetMake(0, 2.0);
[item setBackgroundSelectedImage:backgroundImage withUnselectedImage:backgroundImage];
UIImage *selectedimage = [UIImage imageNamed:[NSString stringWithFormat:@"%@_selected",[tabBarItemImages objectAtIndex:index]]];
UIImage *unselectedimage = [UIImage imageNamed:[NSString stringWithFormat:@"%@_normal",[tabBarItemImages objectAtIndex:index]]];
[item setFinishedSelectedImage:selectedimage withFinishedUnselectedImage:unselectedimage];
[item setTitle:[tabBarItemTitles objectAtIndex:index]];
item.selectedTitleAttributes = @{
NSFontAttributeName: [UIFont boldSystemFontOfSize:12],
NSForegroundColorAttributeName:kNAVIGATION_BAR_COLOR,
};
item.unselectedTitleAttributes = @{
NSFontAttributeName: [UIFont boldSystemFontOfSize:12],
NSForegroundColorAttributeName:RGB(217, 217, 217),
};
[item setTitle:[tabBarItemTitles objectAtIndex:index]];
index++;
}
}
这样你的tabBar基本搭建好了,但是还需要完善一些,比如,角标设置,push隐藏等。
-
Push隐藏tabBar,你只需要这样即可
- (void)viewWillAppear:(BOOL)animated{ [super viewWillAppear:animated]; [[self rdv_tabBarController] setTabBarHidden:YES animated:YES]; }
-
设置角标数
[[self rdv_tabBarItem] setBadgeValue:@"3"];
-
RDVTabBarControllerDelegate,相信你看就会明白,好的方法命名很重要啊~
/** * Asks the delegate whether the specified view controller should be made active. */ - (BOOL)tabBarController:(RDVTabBarController *)tabBarController shouldSelectViewController:(UIViewController *)viewController; /** * Tells the delegate that the user selected an item in the tab bar. */ - (void)tabBarController:(RDVTabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController;
还有需要多等待你去发现...

结语
RDVTabBarController是一个很棒的第三方tabBarController,值得我们学习和思考。
相比传统第三方,你会发现可以很好的定制角标,这是极好的,当然你也可以自定义;
但是不能定义中间凸起的tabBar,好早之前去哪儿就是中间凸起一个tabBar,不过现在去哪儿也改成传统的tabBar了;
