Add click to zoom in and out animation effect to the custom tabBar button in iOS

I thought about implementing animations through third-party methods before, but I felt it was a bit troublesome, so I wrote one by myself

I hope you will point out the shortcomings

// In a sentence, written in a script, tabBar is the method of automatic execution// Click tabbarItem to call automatically-(void)tabBar:(UITabBar *)tabBar didSelectItem:(UITabBarItem *)item 
{ 
NSInteger index = [ indexOfObject:item]; 
[self animationWithIndex:index]; 
if([ isEqualToString:@"Discover"]) 
{ 
// You can also judge the title and do what you want to do<img alt="cell phone" src="/xheditor/xheditor_emot/default/" />} 
} 
- (void)animationWithIndex:(NSInteger) index { 
NSMutableArray * tabbarbuttonArray = [NSMutableArray array]; 
for (UIView *tabBarButton in ) { 
if ([tabBarButton isKindOfClass:NSClassFromString(@"UITabBarButton")]) { 
[tabbarbuttonArray addObject:tabBarButton]; 
} 
} 
CABasicAnimation*pulse = [CABasicAnimation animationWithKeyPath:@""]; 
= [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]; 
 = 0.08; 
= 1; 
= YES; 
= [NSNumber numberWithFloat:0.7]; 
= [NSNumber numberWithFloat:1.3]; 
[[tabbarbuttonArray[index] layer] 
addAnimation:pulse forKey:nil]; 
}

The above is the animation effect of clicking in zoom in and out to the custom tabBar button in iOS introduced by the editor. I hope it will be helpful to everyone.
