升级 iOS18后， TabbarController 切换会带有一个缩放动画，下面是自定义取消动画的代码
#import "TabBarVC.h"@interface TabBarVC () <UIViewControllerAnimatedTransitioning, UITabBarControllerDelegate>@end@implementation TabBarVC- (void)viewDidLoad {[super viewDidLoad];self.delegate = self;
}#pragma mark - UITabBarControllerDelegate
- (nullable id <UIViewControllerAnimatedTransitioning>)tabBarController:(UITabBarController *)tabBarControlleranimationControllerForTransitionFromViewController:(UIViewController *)fromVCtoViewController:(UIViewController *)toVC {return self;
}#pragma mark - UIViewControllerAnimatedTransitioning
- (void)animateTransition:(nonnull id<UIViewControllerContextTransitioning>)transitionContext {UIView *toView = [transitionContext viewForKey:UITransitionContextToViewKey];[transitionContext.containerView addSubview:toView];[transitionContext completeTransition:YES];
}- (NSTimeInterval)transitionDuration:(nullable id<UIViewControllerContextTransitioning>)transitionContext {return 0;
}@end
