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

objectivec 复制代码

#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 *)tabBarController
            animationControllerForTransitionFromViewController:(UIViewController *)fromVC
                                                       toViewController:(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;
}
