更改未选中的UITabBarController项目标题和背景图像的tintColor [英] Change tintColor of unselected UITabBarController item title and background image

问题描述

如何更改未选中的UITabBarItem标题和背景图像iOS 8的tintColor？

How can I change the tintColor of an unselected UITabBarItem title and background image iOS 8?

未选择状态的默认颜色是浅灰色，但在我的黑色阴影上不显示UITabBar背景

The default color for an unselected state is a light gray color, but it does not show on my darkish shade UITabBar background

我希望我的未选择状态的颜色为[UIColor blackColor]

I'd like my unselected state to have a color of [UIColor blackColor]

在我的应用代表中，didfinishlaunchingwithoptions：我有

Inside my app delegate didfinishlaunchingwithoptions: I have

UIImage *deselectedE = [[UIImage imageNamed:@"mincraft_axe_green_32.png"] imageWithRenderingMode:UIImageRenderingModeAutomatic];
UIImage *selectedE = [[UIImage imageNamed:@"mincraft_axe_green_32.png"] imageWithRenderingMode:UIImageRenderingModeAutomatic];
e.tabBarItem =  [[UITabBarItem alloc] initWithTitle:@"Profile" image:deselectedE selectedImage:selectedE];
[[UITabBar appearance] setTintColor:[UIColor blackColor]];

推荐答案

想出来！

用它来改变文本的颜色：

Use this to change the color of the text:

[[UITabBarItem appearance] setTitleTextAttributes:@{ NSForegroundColorAttributeName : [UIColor greenColor] }
                                         forState:UIControlStateNormal];
[[UITabBarItem appearance] setTitleTextAttributes:@{ NSForegroundColorAttributeName : [UIColor blackColor] }
                                         forState:UIControlStateSelected];

并确保图像的图像渲染模式设置为ORIGINAL

And make sure that image rendering mode is set to ORIGINAL for the images

UIImage *deselectedImage = [[UIImage imageNamed:@"deselectedImage"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
UIImage *selectedImage = [[UIImage imageNamed:@"selectedImage"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
