Storyboard 中的TabBarItem的图标颜色

tabbarController的tabBarItem设置图片有两个属性，分别是tabBarItem.image和tabBarItem.selectedImage。一个是选中时显示的图片，另一个是未选中时显示的图片。分别设置上即可。

detailViewController.tabBarItem.image = [notSelectedDetailImage imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
detailViewController.tabBarItem.selectedImage = [selectedDetailImge imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];

如果这个 TabBarController 是从 storyboard 加载的，先写一个 UITabBarController 的子类，然后统一操作

for (UITabBarItem *item in self.tabBar.items) {
        item.image = [item.image imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
        item.selectedImage = [item.selectedImage imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
    }
