UITabBar中的自定义颜色 [英] Custom colors in UITabBar

问题描述

是否可以在UITabBar中使用自定义颜色和背景图像？我意识到Apple希望每个人都使用相同的蓝色和灰色标签栏，但有没有办法自定义它？

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?

第二，即使我是创建自己的像TabBar一样的视图控制器以及自定义图像会违反 Apple的人机界面指南吗？

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 Silent Mac Design 中找到了答案。

我用这种方式实现：

首先制作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

并在您的Nib文件中替换带有CustomUITabBarController的TabBar控制器的类。

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