选择后如何显示不同的标签栏图标颜色

Question

I want know if there is a way to have a different color for different icon selected in a UITabBarController , i know that with this:

[[UITabBar appearance] setTintColor:[UIColor whiteColor]];

i can change the selection color for all icon, but how i can do it for different tab?

Answer 1

One way of doing this, would be by simply changing the tint color of the tabbar in the different viewcontrollers.

Let's say for example you have 3 different tabs: tab1 , tab2 and tab3 , all of which are displaying different viewcontrollers. Now, let's say you want to have a blue tint color in tab1 but a red tint color in tab2 and tab3 . Then, you can simply add the following line to the viewWillAppear: method of the different ViewControllers .

For the first viewController, which is shown in tab1 , you'd have:

//In your viewcontroller which is shown in tab1
- (void)viewWillAppear:(BOOL)animated {
   [super viewWillAppear:animated];
   // change tint color to blue
   [self.tabBarController.tabBar setTintColor:[UIColor blueColor]];
}

And for the other two, you simply put another color:

//In your viewcontrollers which are shown in tab2 and tab3
- (void)viewWillAppear:(BOOL)animated {
   [super viewWillAppear:animated];
   // change tint color to red
   [self.tabBarController.tabBar setTintColor:[UIColor redColor]];
}

It's that simple. There are certainly other ways of doing this, but this one is pretty clean and straightforward.
