详解iOS App中UiTabBarController组件的基本用法

4> 当底部的按钮超过5个时，系统会自动增加一个more按钮，点击more后，剩余的按钮会被显示出来。

 

8.UITabbarController左右滑动切换标签页  
每个Tabbar ViewController都要添加如下代码，建议在基类中添加：

复制代码
ViewDidLoad
UISwipeGestureRecognizer *swipeLeft = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(tappedRightButton:)];

 

    [swipeLeft setDirection:UISwipeGestureRecognizerDirectionLeft];

    [self.view addGestureRecognizer:swipeLeft];

   

    UISwipeGestureRecognizer *swipeRight = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(tappedLeftButton:)];

    [swipeRight setDirection:UISwipeGestureRecognizerDirectionRight];

    [self.view addGestureRecognizer:swipeRight];

 

再添加2个函数，包含切换动画效果：

复制代码
- (IBAction) tappedRightButton:(id)sender

 

{

    NSUInteger selectedIndex = [self.tabBarController selectedIndex];

   

    NSArray *aryViewController = self.tabBarController.viewControllers;

    if (selectedIndex < aryViewController.count - 1) {

        UIView *fromView = [self.tabBarController.selectedViewController view];
