在“更多”菜单中更改UITabBar色调颜色

I'm trying to change the blue colour from icons in the more menu. I tried almost everything I found on Stack Overflow, but nothing worked. I tried this solution, but is not working.

我正在尝试从更多菜单中的图标更改蓝色。我尝试了几乎所有我在Stack Overflow上找到的东西,但没有任何效果。我试过这个解决方案,但是没有用。

The only option I found to change the colour was

我发现改变颜色的唯一选择是

[[UIView appearance] setTintColor:[UIColor redColor]];

but it changes all colours in the app.

但它改变了应用程序中的所有颜色。

The code is just a new project with storyboard, so I just added the views on the storyboard.
Thanks for helping.

代码只是一个带有故事板的新项目,所以我只是在故事板上添加了视图。谢谢你的帮助。

Edit: After I added the code:

编辑:我添加代码后:

    UIImage *myImage = [[UIImage imageNamed:@"music.png"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
self.tabBarItem = [[UITabBarItem alloc] initWithTitle:@"New Title" image:myImage selectedImage:[UIImage imageNamed:@"music.png"]];

The image is changed when the view is selected, but it's still blue.

选择视图时图像会发生变化,但仍然是蓝色。

To do what you need, you should use images by creating UITabBarItem for each controller and add an image and a selected image.

要做你需要的,你应该通过为每个控制器创建UITabBarItem来使用图像,并添加图像和选定的图像。

See Apple Documentation about UITabBarItem

请参阅有关UITabBarItem的Apple文档

Edit after seing the full code First there is many mistakes in your project, assets should be in xcassets folder, in view didload write your code after the 'super viewDidLoad]', etc.

在查看完整代码后进行编辑首先,你的项目中存在很多错误,资产应该在xcassets文件夹中,在视图中,在'super viewDidLoad'之后写入你的代码,等等。

About your problem, in your viewDidLoad method in the FirstViewController

关于您的问题,在FirstViewController的viewDidLoad方法中

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    // Your code start here, not before the super
    [[UITabBar appearance] setTintColor:[UIColor redColor]];

    // Get table view of more new viewController
    UITableView *view =(UITableView*)self.tabBarController.moreNavigationController.topViewController.view;

    view.tintColor = [UIColor redColor]; // Change the image color

    if ([[view subviews] count]) {
        for (UITableViewCell *cell in [view visibleCells]) {
            cell.textLabel.textColor = [UIColor redColor]; // Change the text color

        }
    }
}

This is the Swift version of Ludovic's answer.

这是Ludovic答案的Swift版本。

Keep in mind that this version only changes the tint color, since the original answer did the text color change in a very hacky way. For changing it properly, you'd have to override moreNavigationController and its cellForRowAt function.

请记住,此版本仅更改色调颜色,因为原始答案以非常黑客的方式更改了文本颜色。要正确更改它,您必须覆盖moreNavigationController及其cellForRowAt函数。

tabBarController?.tabBar.tintColor = .red

if let moreTableView = tabBarController?.moreNavigationController.topViewController?.view as? UITableView {
    moreTableView.tintColor = .red
}
