iOS custom tabbar
提问by woutr_be
I just started with iOS development and am just playing around atm.
我刚开始使用 iOS 开发，只是在玩 atm。
I'm trying to transform the default tabbar buttons into something more custom.
我正在尝试将默认标签栏按钮转换为更自定义的按钮。
After some looking around I found you can create custom states for every button, so I did:
环顾四周后，我发现您可以为每个按钮创建自定义状态，所以我做到了：
UIImage *selectedImage0 = [UIImage imageNamed:@"first.png"];
UIImage *unselectedImage0 = [UIImage imageNamed:@"second.png"];
UITabBar *tabBar = self.tabBarController.tabBar;
UITabBarItem *item0 = [tabBar.items objectAtIndex:0];
[item0 setFinishedSelectedImage:selectedImage0 withFinishedUnselectedImage:unselectedImage0];
However, I can't get rid of the default button, it changes the image, but it doesn't change my entire button.
但是，我无法摆脱默认按钮，它会更改图像，但不会更改我的整个按钮。
Is there something else I need to do?
还有什么我需要做的吗？
UIViewController *viewController1 = [[FirstViewController alloc] initWithNibName:@"FirstViewController" bundle:nil];
UIViewController *viewController2 = [[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle:nil];
self.tabBarController = [[UITabBarController alloc] init];
self.tabBarController.viewControllers = [NSArray arrayWithObjects:viewController1, viewController2, nil];
self.window.rootViewController = self.tabBarController;
[self.window makeKeyAndVisible];
UIImage *selectedImage0 = [UIImage imageNamed:@"first.png"];
UIImage *unselectedImage0 = [UIImage imageNamed:@"second.png"];
UITabBar *tabBar = self.tabBarController.tabBar;
UITabBarItem *item0 = [tabBar.items objectAtIndex:0];
[item0 setFinishedSelectedImage:selectedImage0 withFinishedUnselectedImage:unselectedImage0];

Here i've created a custom tab bar and images i took are in a constant file. Here you can replace the image with "foo.png" as per your convenience. Here the serivceImg, contactImg etc are UIImageView which is declared in .h file. Also, don't forget to add UITabBarControllerDelegate as a delegate in your .h file.
在这里，我创建了一个自定义标签栏，我拍摄的图像位于一个常量文件中。在这里，您可以根据自己的方便用“foo.png”替换图像。这里的 serivceImg、contactImg 等是在 .h 文件中声明的 UIImageView。另外，不要忘记在 .h 文件中添加 UITabBarControllerDelegate 作为委托。
