Question

我正在使用带有以下代码的自定义标签栏：

UIImage *selectedImage0 = [UIImage imageNamed:@"HomeDB.png"];
UIImage *unselectedImage0 = [UIImage imageNamed:@"HomeLB.png"];    
UIImage *selectedImage1 = [UIImage imageNamed:@"ScheduleDB.png"];
UIImage *unselectedImage1 = [UIImage imageNamed:@"ScheduleLB.png"];

UIImage *selectedImage2 = [UIImage imageNamed:@"BuildingsDB.png"];
UIImage *unselectedImage2 = [UIImage imageNamed:@"BuildingsLB.png"];

UIImage *selectedImage3 = [UIImage imageNamed:@"InformationDB.png"];
UIImage *unselectedImage3 = [UIImage imageNamed:@"InformationLB.png"];

UIImage *selectedImage4 = [UIImage imageNamed:@"MoreDB.png"];
UIImage *unselectedImage4 = [UIImage imageNamed:@"MoreLB.png"];

UITabBar *tabBar = self.tabBarController.tabBar;

tabBar.tintColor = [UIColor redColor];
UITabBarItem *item0 = [tabBar.items objectAtIndex:0];
UITabBarItem *item1 = [tabBar.items objectAtIndex:1];
UITabBarItem *item2 = [tabBar.items objectAtIndex:2];
UITabBarItem *item3 = [tabBar.items objectAtIndex:3];
UITabBarItem *item4 = [tabBar.items objectAtIndex:4];

[item0 setFinishedSelectedImage:selectedImage0 withFinishedUnselectedImage:unselectedImage0];
[item1 setFinishedSelectedImage:selectedImage1 withFinishedUnselectedImage:unselectedImage1];
[item2 setFinishedSelectedImage:selectedImage2 withFinishedUnselectedImage:unselectedImage2];
[item3 setFinishedSelectedImage:selectedImage3 withFinishedUnselectedImage:unselectedImage3];
[item4 setFinishedSelectedImage:selectedImage4 withFinishedUnselectedImage:unselectedImage4];

我的问题是当自定义标签栏时，标签栏的底部仍然有一个视图（我将颜色设置为红色）。看起来像这样：

无论如何在没有隐藏默认标签栏的情况下将其删除并将其替换为自定义视图？我在Stackoverflow中检查它，在UITabbar参考中，但仍然找不到。

我认为这就是你想要的，替换你的自定义tabBar：

- (void)oppoHideTabBarViewController
    {
        if (self.tabBarViewController.tabBar.hidden == YES)
        {
            return;
        }

        UIView *contentView;

        if ( [[self.tabBarViewController.view.subviews objectAtIndex:0] isKindOfClass:[UITabBar class]] )
        {
            contentView = [self.tabBarViewController.view.subviews objectAtIndex:1];
        }
        else
        {
            contentView = [self.tabBarViewController.view.subviews objectAtIndex:0];
        }

        contentView.frame = CGRectMake(contentView.bounds.origin.x,
                                       contentView.bounds.origin.y,
                                       contentView.bounds.size.width,
                                       contentView.bounds.size.height + self.tabBarViewController.tabBar.frame.size.height);

        self.tabBarViewController.tabBar.hidden = YES;

    }

    - (void)oppoShowTabBarViewController
    {
        if (self.tabBarViewController.tabBar.hidden == NO)
        {
            return;
        }

        UIView *contentView;

        if ([[self.tabBarViewController.view.subviews objectAtIndex:0] isKindOfClass:[UITabBar class]])
        {
            contentView = [self.tabBarViewController.view.subviews objectAtIndex:1];
        }
        else
        {
            contentView = [self.tabBarViewController.view.subviews objectAtIndex:0];
        }

        contentView.frame = CGRectMake(contentView.bounds.origin.x,
                                       contentView.bounds.origin.y,
                                       contentView.bounds.size.width,
                                       contentView.bounds.size.height - self.tabBarViewController.tabBar.frame.size.height);

        self.tabBarViewController.tabBar.hidden = NO;
    }

你试试：

- (void)hideTabBar:(UITabBarController *) tabbarcontroller
{   
    for(UIView *view in tabbarcontroller.view.subviews)
    {
        if([view isKindOfClass:[UITabBarclass]])
        {
            [view setFrame:CGRectMake(view.frame.origin.x, 480, view.frame.size.width, view.frame.size.height)];
        }
        else
        {
            [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y + 36, view.frame.size.width, 480 - 36)];
        }
    }
}
