我无法使用故事板提供彩色的UItabbar项目图片。请提前帮助我。谢谢。

Answer 1

只需在项目中添加CustomTabbarController并设置TabBarController类CustomTabbarController，这对您有用。

#import "CustomTabbarController.h"
#import "FirstViewController.h"
#import "SecondViewController.h"
#import "ThirdViewController.h"

@implementation CustomTabbarController

- (void)viewDidLoad
{
    [super viewDidLoad]; 

    FirstViewController *first = [[FirstViewController alloc]init];
    SecondViewController *second = [[SecondViewController alloc]init];
    ThirdViewController *third = [[ThirdViewController alloc]init];


    [self setViewControllers:[NSArray arrayWithObjects:first, second, third, nil]];  

    UIImage *selectedImage0 = [UIImage imageNamed:@"home-active.png"];
    UIImage *unselectedImage0 = [UIImage imageNamed:@"home.png"];

    UIImage *selectedImage1 = [UIImage imageNamed:@"star-active.png"];
    UIImage *unselectedImage1 = [UIImage imageNamed:@"star.png"];

    UIImage *selectedImage2 = [UIImage imageNamed:@"search-active.png"];
    UIImage *unselectedImage2 = [UIImage imageNamed:@"search.png"]; 

    UITabBar *tabBar = self.tabBar;
    UITabBarItem *item0 = [tabBar.items objectAtIndex:0];
    UITabBarItem *item1 = [tabBar.items objectAtIndex:1];
    UITabBarItem *item2 = [tabBar.items objectAtIndex:2]; 

    [item0 setFinishedSelectedImage:selectedImage0 withFinishedUnselectedImage:unselectedImage0];
    [item1 setFinishedSelectedImage:selectedImage1 withFinishedUnselectedImage:unselectedImage1];
    [item2 setFinishedSelectedImage:selectedImage2 withFinishedUnselectedImage:unselectedImage2];
}

@end

您需要为此创建自定义标签栏。

希望它对你有所帮助。

干杯！

Answer 3

是的，你不能在故事板中这样做。

现在，故事板只支持图标类型的色调图像。

但您可以设置要通过代码设置的任何图像。

如果您不了解代码并希望得到一些帮助而不是评论我可能会帮助。
