storyboard tabbarcontroller设置tab的图片

在storyboard里逐项设置了图片,咦,怎么是颜色?别急,慢慢来

找到你的tabbarcontroller指向的viewcontroller,在viewdidload里做如下事,搞定

- (void)viewDidLoad {
    [super viewDidLoad];
 
    UITabBar *tabBar = self.tabBar;

    
    UIView *backView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, tabBar.frame.size.width, tabBar.frame.size.height)];
    backView.backgroundColor = [UIColor whiteColor];
    [tabBar insertSubview:backView atIndex:0];
    
    UITabBarItem *item0 = [tabBar.items objectAtIndex:0];
    UITabBarItem *item1 = [tabBar.items objectAtIndex:1];
    UITabBarItem *item2 = [tabBar.items objectAtIndex:2];
    UITabBarItem *item3 = [tabBar.items objectAtIndex:3];
    
    item0.image = [[UIImage imageNamed:@"shouye2"]imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
    item0.selectedImage = [[UIImage imageNamed:@"shouye1"]imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];

    item1.image = [[UIImage imageNamed:@"shoucang2"]imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
    item1.selectedImage = [[UIImage imageNamed:@"shoucang1"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];

    item2.image = [[UIImage imageNamed:@"xiaoxi2"]imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
    item2.selectedImage = [[UIImage imageNamed:@"xiaoxi1"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];

    item3.image = [[UIImage imageNamed:@"wode2"]imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
    item3.selectedImage = [[UIImage imageNamed:@"wode1"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
    
    
    [[UITabBarItem appearance] setTitleTextAttributes: [NSDictionary dictionaryWithObjectsAndKeys:
                                                        [UIColor redColor],
                                                        UITextAttributeTextColor, nil] forState:UIControlStateSelected];
}
