setSelectedImageTintColor在iOS 7中不起作用

问题描述

我在iOS 7中尝试 setSelectedImageTintColor ，但它无效。这是我在 AppDelegate.m 下的代码 didFinishLaunchingWithOptions

I'm trying to setSelectedImageTintColor in iOS 7, but it's not working. Here's the code that I have in my AppDelegate.m under didFinishLaunchingWithOptions

UITabBarController *tabBarController = (UITabBarController *) self.window.rootViewController;
UITabBar *tabBar = tabBarController.tabBar;

for (UITabBarItem *item in tabBar.items)
    {
        UIImage *image = item.image;
        UIImage *correctImage = [image imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate];
        item.image = correctImage;
    }

[[UITabBar appearance] setTintColor:[UIColor whiteColor]];
[[UITabBar appearance] setSelectedImageTintColor:[UIColor colorWithRed:44.0/255.0 green:176.0/255.0 blue:28.0/255.0 alpha:1.0]];
[[UITabBar appearance] setBarTintColor:[UIColor colorWithRed:51.0/255.0 green:51.0/255.0 blue:51.0/255.0 alpha:1.0]];

它仍然不会显示selectedImageTintColor。选中时它是白色的;未选中时为灰色。我做错了什么？

It still won't show the selectedImageTintColor. It's white when selected; gray when unselected. What am I doing wrong?

推荐答案

这是iOS 7中的一个已知问题。 tintColor 用于选定的标签图像。完全忽略 selectedImageTintColor 。无法对未选中的标签图像进行着色。

This is a known issue in iOS 7. The tintColor is used for the selected tab image. The selectedImageTintColor is completely ignored. There is no way to tint unselected tab images.
