UITabBar 中的自定义颜色

本文介绍了UITabBar 中的自定义颜色的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

是否可以在 UITabBar 中使用自定义颜色和背景图像?我知道 Apple 希望每个人都使用相同的蓝色和灰色标签栏，但有什么方法可以自定义吗?

Is it possible to use custom colors and background images in a UITabBar? I realize that Apple would like everyone to use the same blue and gray tab bars, but is there any way to customize this?

其次，即使我要创建自己的类似 TabBar 的视图控制器以及自定义图像，这是否会违反 Apple 的人机界面指南?

Second, even I were to create my own TabBar-like view controller, along with custom images, would this violate Apple's Human Interface Guidelines?

推荐答案

我在 静音 Mac 设计.

我是这样实现的:

首先创建一个UITabBarContoller的子类

First make a subclass of UITabBarContoller

// CustomUITabBarController.h #import <UIKit/UIKit.h> @interface CustomUITabBarController: UITabBarController { IBOutlet UITabBar *tabBar1; } @property(nonatomic, retain) UITabBar *tabBar1; @end

// CustomUITabBarController.m #import "CustomUITabBarController.h" @implementation CustomUITabBarController @synthesize tabBar1; - (void)viewDidLoad { [super viewDidLoad]; CGRect frame = CGRectMake(0.0, 0, self.view.bounds.size.width, 48); UIView *v = [[UIView alloc] initWithFrame:frame]; [v setBackgroundColor:[[UIColor alloc] initWithRed:1.0 green:0.0 blue:0.0 alpha:0.1]]; [tabBar1 insertSubview:v atIndex:0]; [v release]; } @end

在你的 Nib 文件中，用 CustomUITabBarController 替换你的 TabBar 控制器的类.

And in your Nib file replace the class of your TabBar Controller with CustomUITabBarController.
