“更多"的徽章价值标签 [英] Badge value on "More" tab

问题描述

我正在制作一个带有tabBarController的iOS应用，该应用带有超过5个选项卡.因此，前四个可以直接单击，其余的位于更多"标签下.

I am making an iOS app which has a tabBarController, with more than 5 tabs. Thus, first four are directly clickable and the rest come under MORE tab.

如果该更多"选项卡中隐藏的选项卡有任何标志，我想在更多"选项卡上显示标志.

I want to show a badge on the MORE tab if there is any badge for the tabs that are hidden inside this MORE tab.

我从但是选项卡的顺序是可配置的.有没有一种方法可以配置更多"选项卡，如果我在其中设置了选项卡的值，它只会放入badgeValue?

But the order of my tabs is configurable. Is there a way I can configure the MORE tab such it just puts the badgeValue if I set a value for a tab inside it?

我正在考虑:

- (void)updateBadgeValue:(NSInteger)count {
    int index = [self.tabBarController indexOfObject:self.tabBarItem];
    if (index > 4) { //Inside MORE tab
        [[[self.tabBarController moreTabBarController] tabBarItem] setBadgeValue:[NSString stringWithFormat:@"%d", count]];
    }
    //Also setting badge of self.tabbarItem so that it remains when it is brought to "hot tab items".
}

我正在寻找一种解决方案，使我不必为每个选项卡都这样做.另外，如果用户更改了制表符顺序，则badgeValue也应相应更新.

I am looking for a solution such that I dont have to do that for every tab. Also, if the tab order is changed by the user, the badgeValue should also update accordingly.

谢谢.

推荐答案

尝试使用此功能:

- (void)updateBadgeValue:(NSInteger)count {
    int index = [self.tabBarController indexOfObject:self.tabBarItem];
    if (index > 4) {
        int moreTabCount = count + [[[[self.tabBarController moreTabBarController] tabBarItem] badgeValue] intValue];
        [[[self.tabBarController moreTabBarController] tabBarItem] setBadgeValue:[NSString stringWithFormat:@"%d", moreTabCount]];
    }
}

更新:您可以使用

- (void)tabBarController:(UITabBarController *)tabBarController didEndCustomizingViewControllers:(NSArray *)viewControllers changed:(BOOL)changed

您的 UITabBarController 的委托中的

delegate方法(应为 AppDelegate ).做吧:

delegate method in your UITabBarController's delegate (it should be AppDelegate). Let's do it:

- (void)tabBarController:(UITabBarController *)tabBarController didEndCustomizingViewControllers:(NSArray *)viewControllers changed:(BOOL)changed {
    if(changed) {
        int count = 0;
        int i; for(i = 4; i < [viewControllers count]; i++)
            count += [[[[viewControllers objectAtIndex:i] tabBarItem] badgeValue] intValue];
        if(count > 0)
            [[self.tabBarController moreTabBarController] tabBarItem] setBadgeValue:[NSString stringWithFormat:@"%d", count]];
    }
}

我认为它将起作用.
