Question

我在我的应用中添加了tabbar。我一次显示5个标签。我正在尝试制作标签栏的自定义颜色。我在TabBarController

中使用了以下内容

UITabBarItem *homeTab = [self.exposeTabBar.items objectAtIndex:0];
    UIImage *home_unselectedImage = [UIImage imageNamed:@"home.png"];
    UIImage *home_selectedImage = [UIImage imageNamed:@"home.png"];
    [homeTab setImage: [home_unselectedImage imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];
    [homeTab setSelectedImage: home_selectedImage];

    UITabBarItem *bookmarkTab = [self.exposeTabBar.items objectAtIndex:1];
    UIImage *bookmark_unselectedImage_ = [UIImage imageNamed:@"bookmark.png"];
    UIImage *bookmark_selectedImage = [UIImage imageNamed:@"bookmark.png"];
    [bookmarkTab setImage: [bookmark_unselectedImage_ imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];
    [bookmarkTab setSelectedImage: bookmark_selectedImage];

    UITabBarItem *postTab = [self.exposeTabBar.items objectAtIndex:2];
    UIImage *post_unselectedImage_ = [UIImage imageNamed:@"create-post.png"];
    UIImage *post_selectedImage = [UIImage imageNamed:@"create-post_white.png"];
    [postTab setImage: [post_unselectedImage_ imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];
    [postTab setSelectedImage: post_selectedImage];

    UITabBarItem *notificationTab = [self.exposeTabBar.items objectAtIndex:3];
    UIImage *notification_unselectedImage_ = [UIImage imageNamed:@"notifications.png"];
    UIImage *notification_selectedImage = [UIImage imageNamed:@"notifications_white.png"];
    [notificationTab setImage: [notification_unselectedImage_ imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];
    [notificationTab setSelectedImage: notification_selectedImage];

    UITabBarItem *profileTab = [self.exposeTabBar.items objectAtIndex:4];
    UIImage *profile_unselectedImage_ = [UIImage imageNamed:@"user-profile.png"];
    UIImage *profile_selectedImage = [UIImage imageNamed:@"user-profile_white.png"];
    [profileTab setImage: [profile_unselectedImage_ imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];
    [profileTab setSelectedImage: profile_selectedImage];

对于未选择的图像，它显示的是正确的图像，但对于所选的图像，它没有显示正确的图像。它显示图标的蓝色图像。

请告诉我该如何防止这种情况？

Answer 1

在app delegate：

中尝试使用带有清晰颜色的标签栏外观api方法

[[UITabBar appearance] setTintColor:[UIColor clearColor]];

Answer 2

尝试更改 tabBar颜色和 tabBar色调 例如：

// Generate a black tab bar

self.tabBarController.tabBar.barTintColor = [UIColor blackColor];



// Set the selected icons and text tint color

self.tabBarController.tabBar.tintColor = [UIColor orangeColor];

Answer 3

尝试更改tabBarController的“tabEdgeColor”和“topEdgeColor”。

或者更改tabBar的barTint或色调颜色以清除颜色。

Answer 4

对于选定的图像，您还应该设置渲染模式，试试这个：

[homeTab setSelectedImage:[home_selectedImage imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];

Answer 5

您可以将自定义图像用于不同的颜色

tabBarItem1.image = [[UIImage imageNamed:"imag"]imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal ];
tabBarItem1.selectedImage = [[UIImage imageNamed:@"selected_image"]imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal ];

标签栏按钮在iOS中始终显示蓝色？
