在iAbbar iOS中更改项目颜色

我的应用程序有一个选项卡栏，如下所示：

选项卡栏必须是绿色的，正如您所看到的，选项卡栏中项目的图标有点难以看到。如何更改此选项卡栏中图标的颜色？我必须使用标准选项卡栏。 谢谢

试试这个

[[self tabBar] setSelectedImageTintColor:[UIColor greenColor]]; 

还是这个

[UITabBarItem.appearance setTitleTextAttributes:@{
    UITextAttributeTextColor : [UIColor greenColor] } forState:UIControlStateNormal];

[UITabBarItem.appearance setTitleTextAttributes:@{
    UITextAttributeTextColor : [UIColor purpleColor] }     forState:UIControlStateSelected];

    [UITabBarItem.appearance setTitleTextAttributes:@{NSForegroundColorAttributeName : [UIColor greenColor]} forState:UIControlStateNormal];    
   [UITabBarItem.appearance setTitleTextAttributes:@{NSForegroundColorAttributeName : [UIColor purpleColor]} forState:UIControlStateSelected];

还是这个

[[self tabBar] setTintColor:[UIColor redColor]];

还是这个

[UITabBarItem.appearance setTitleTextAttributes:@{
    UITextAttributeTextColor : [UIColor greenColor] } forState:UIControlStateNormal];

[UITabBarItem.appearance setTitleTextAttributes:@{
    UITextAttributeTextColor : [UIColor purpleColor] }     forState:UIControlStateSelected];

    [UITabBarItem.appearance setTitleTextAttributes:@{NSForegroundColorAttributeName : [UIColor greenColor]} forState:UIControlStateNormal];    
   [UITabBarItem.appearance setTitleTextAttributes:@{NSForegroundColorAttributeName : [UIColor purpleColor]} forState:UIControlStateSelected];

试试这个

[[UITabBar appearance] setTintColor:[UIColor redColor]];
[[UITabBar appearance] setBarTintColor:[UIColor yellowColor]];

// set tabbar background image
[[UITabBar appearance] setBackgroundImage:[UIImage imageNamed:@"tabbar_bg"]];
// remove shadow image of tabbar
[[UITabBar appearance] setShadowImage:[[UIImage alloc]init]];

您可以使用以下代码来使用图标图像，而不是使用图标

UITabBar *tabBar = tabBarController.tabBar;
UITabBarItem *tabBarItem1 = [tabBar.items objectAtIndex:0];

tabBarItem1.selectedImage = [[UIImage imageNamed:@"selectedImage.png"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal ];
tabBarItem1.image = [[UIImage imageNamed:@"unselectedImage.png"]imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal ];
tabBarItem1.imageInsets= UIEdgeInsetsMake(6, 0, -6, 0);

我建议，将UITabbar的背景颜色改为一些较深的颜色，而不是绿色。对于未选中的选项卡，只需保留默认的灰色（苹果遮罩为灰色）。使用“下剪”设置选定选项卡遮罩颜色

[[UITabBar外观]setTintColor:[UIColor REDCLOR]]

这将避免最终用户混淆选项卡是处于选中状态还是处于未选中状态。
