在显示弹出窗口时设置标签栏图标的颜色? [英] Setting the tab bar icon color when popup is shown?

问题描述

我已经能够根据需要为我的标签栏项设置文本和图标的颜色.白色表示未激活，蓝色表示正在激活.

I was already able to set the text and icon colors for my tab bar items as desired. White for not active, blue for active.

但是，我仍然遇到一个问题: 显示弹出视图或警报视图时，选项卡栏项目图标显示为灰色:

However, I still run into one issue: When a popover or alert view is shown, the tab bar item icon is greyed out:

在这种状态下是否有可能保持蓝色?

Is there any possibility to keep the blue color for this state?

感谢您的帮助.

很抱歉，我的问题不是重复的.我已经做了所有这些事情:

I'm sorry, but my question is not a duplicate. I already do all these things:

self.tabBar.tintColor = COLOR_CORPORATE_BLUE;
[[UITabBarItem appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
                                                   [UIColor whiteColor], NSForegroundColorAttributeName,
                                                   nil] forState:UIControlStateNormal];
[[UITabBarItem appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
                                                   COLOR_CORPORATE_BLUE, NSForegroundColorAttributeName,
                                                   nil] forState:UIControlStateSelected];

NSUInteger i = 0;
NSString *imageName = @"";
for (UITabBarItem *item in self.tabBar.items) {
    switch (i) {
        case 0: imageName = @"home_tab_db"; break;
        case 1: imageName = @"home_tab_al"; break;
        case 2: imageName = @"home_tab_ru"; break;
        case 3: imageName = @"home_tab_da"; break;
    }

    UIImage *img = [UIImage imageNamed:imageName];
    if ([img respondsToSelector:@selector(imageWithRenderingMode:)]) {
        item.image = [img imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
    } else {
        item.image = img;
    }
    item.selectedImage = [UIImage imageNamed:[imageName stringByAppendingString:@"_active"]];

    i++;
}

但是，正如我所写的那样，任何弹出窗口，警报视图等都将使活动图标的颜色变为灰色.

However, as I've written, any popover, alert view, etc. will change the color of my active icon to grey.

推荐答案

self.tabBar.tintAdjustmentMode = UIViewTintAdjustmentModeNormal;

完成工作.
