RDVTabBarController
- 支持 iPad 和 iPhone
- 支持横竖屏
- 可在 UINavigationController 内使用
- 可定制徽章
安装
CocoaPods
如果您使用 CocoaPods，只需在 Podfile 中添加 pod 'RDVTabBarController' 即可。
拖放
将 RDVTabBarController 目录中的项添加到您的项目中。如果您未启用 ARC，需要将 -fobjc-arc 编译器标志设置在 .m 源文件上。
示例用法
初始化RDVTabBarController
初始化方式与UITabBarController相似。创建tabBarController的实例并初始化其viewControllers。
UIViewController *firstViewController = [[RDVFirstViewController alloc] init];
UIViewController *firstNavigationController = [[UINavigationController alloc]
initWithRootViewController:firstViewController];
UIViewController *secondViewController = [[RDVSecondViewController alloc] init];
UIViewController *secondNavigationController = [[UINavigationController alloc]
initWithRootViewController:secondViewController];
UIViewController *thirdViewController = [[RDVThirdViewController alloc] init];
UIViewController *thirdNavigationController = [[UINavigationController alloc]
initWithRootViewController:thirdViewController];
RDVTabBarController *tabBarController = [[RDVTabBarController alloc] init];
[tabBarController setViewControllers:@[firstNavigationController, secondNavigationController,
thirdNavigationController]];
self.viewController = tabBarController;自定义RDVTabBarController
每个RDVTabBarItem都拥有selectedBackground、unselectedBackground以及对应图标的属性：selectedImage和unselectedImage。
UIImage *finishedImage = [UIImage imageNamed:@"tabbar_selected_background"];
UIImage *unfinishedImage = [UIImage imageNamed:@"tabbar_normal_background"];
NSArray *tabBarItemImages = @[@"first", @"second", @"third"];
RDVTabBar *tabBar = [tabBarController tabBar];
[tabBar setFrame:CGRectMake(CGRectGetMinX(tabBar.frame), CGRectGetMinY(tabBar.frame), CGRectGetWidth(tabBar.frame), 63)];
NSInteger index = 0;
for (RDVTabBarItem *item in [[tabBarController tabBar] items]) {
[item setBackgroundSelectedImage:finishedImage withUnselectedImage:unfinishedImage];
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];
index++;
}使标签栏透明
RDVTabBar拥有一个translucent属性，用于确定其处理方式。
RDVTabBar *tabBar = tabBarController.tabBar;
// After the tabBarController initialization
tabBar.translucent = YES;
// Customize the tabBar background
tabBar.backgroundView.backgroundColor = [UIColor colorWithRed:245/255.0
green:245/255.0
blue:245/255.0
alpha:0.9];
// Inside the tabbed viewControllers
- (void)viewDidLoad {
[super viewDidLoad];
...
if (self.rdv_tabBarController.tabBar.translucent) {
CGFloat tabBarHeight = CGRectGetHeight(self.rdv_tabBarController.tabBar.frame);
UIEdgeInsets insets = UIEdgeInsetsMake(0, 0, tabBarHeight, 0);
self.tableView.contentInset = insets;
self.tableView.scrollIndicatorInsets = insets;
}
}
