UITabBar項目主題設置問題

Question

在應用啟動時，我通過設置白色圖像將所有標簽欄圖標的顏色更改為白色。 問題是更多菜單按鈕在未選中時似乎無法更改其灰色。是否有特殊方法可以解決此問題？

編輯：我嘗試以下代碼沒有成功：

[((UITabBarItem*)[self.tabBar.items objectAtIndex:4]) setImage:[[UIImage imageNamed:@"more_unselected"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];
[((UITabBarItem*)[self.tabBar.items objectAtIndex:4]) setSelectedImage:[[UIImage imageNamed:@"more_selected"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];

Answer 1

設置圖像的渲染模式，例如：-

self.tabBarItem.selectedImage = [[UIImage imageNamed:@"yourImage_selectedImage"]
imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];

self.tabBarItem.image = [[UIImage imageNamed:@"yourImage_image"] 
    imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
