1.有时，我们需要为tabBarItem设置一些动画。在网上查了半天，没有结果。自己写了一个简单的bounce效果的动画
代码如下：
代码如下：
- (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController{
NSInteger currentIndex = tabBarController.selectedIndex;
NSInteger index = 0;
UITabBar *tabBar = tabBarController.tabBar;
for (int i = 0; i < tabBar.subviews.count; i++) {
UIView *button = tabBar.subviews[i];
if ([button isKindOfClass:NSClassFromString(@"UITabBarButton")]) {
if (index != currentIndex) {
index++;
}
else{
CAKeyframeAnimation *animation = [[CAKeyframeAnimation alloc]init];
animation.keyPath = @"transform.scale";
animation.duration = 1.0;
animation.values = @[@(1.0) ,@(1.4), @(0.9), @(1.15), @(0.95), @(1.02), @(1.0)];
UIView *imageview = [button.subviews firstObject];
//view.backgroundColor = [UIColor greenColor];
[imageview.layer addAnimation: animation forKey:nil];
UIView *labelview = [button.subviews lastObject];
[labelview.layer addAnimation:animation forKey:nil];
break;
}
}
}
}
