标签栏与大图标

Question

我想知道是否有办法完成一个只有大图标的标签栏,我附上了一张图片供参考.我对创建自己的标签栏控制器以及自己管理视图控制器不感兴趣.

Answer 1

这是我的解决方案,我创建了一个类,它是一个子类UITabBarController.

CustomTabBarController.h

@interface CustomTabBarController : UITabBarController<UITabBarControllerDelegate>
@property (strong, nonatomic) IBOutlet UITabBar *tabBar;
@end

CustomTabBarController.m

- (void)viewDidLoad
{
    CGRect tabBarFrame = self.tabBar.frame ;
    tabBarFrame.origin.y -= kOrigin;
    tabBarFrame.size.height = kTabBarHeight;
    self.tabBar.frame = tabBarFrame;
    self.tabBarController.delegate = self;
    /* Tab Bar Background */

    UIImage *tabBarBackgroundImage = [UIImage imageNamed:@"tabBarBackgroundImage.png"];
    [[UITabBar appearance] setBackgroundImage:tabBarBackgroundImage];

    /* Tab Bar Item */
    UIButton *surveyButton = [UIButton buttonWithType:UIButtonTypeCustom];
    [surveyButton addTarget:self action:@selector(surveyButtonDidSelect) forControlEvents:UIControlEventTouchUpInside];
    surveyButton.tag = surveyButtonTag;
    [surveyButton setBackgroundImage:[UIImage imageNamed:@"someimage.png"] forState:UIControlStateNormal];
    CGRect surveyButtonFrame = surveyButton.frame ;
    surveyButtonFrame.origin.x = /*Proper value in your case */;
    surveyButtonFrame.origin.y = /*Proper value in your case */;
    surveyButtonFrame.size.height = /*Proper value in your case */ ;
    surveyButtonFrame.size.width =/*Proper value in your case */;
    surveyButton.frame = surveyButtonFrame;
    [self.tabBar addSubview:surveyButton];

    UIButton *statusButton = [UIButton buttonWithType:UIButtonTypeCustom];
    statusButton.tag = statusButtonTag;
    [statusButton addTarget:self action:@selector(statusButtonDidSelect) forControlEvents:UIControlEventTouchUpInside];
    [statusButton setBackgroundImage:[UIImage imageNamed:@"someimage.png"] forState:UIControlStateNormal];
    CGRect statusButtonFrame = statusButton.frame ;
    statusButtonFrame.origin.x = /*Proper value in your case */;
    statusButtonFrame.origin.y = /*Proper value in your case */;
    statusButtonFrame.size.height = /*Proper value in your case */;
    statusButtonFrame.size.width = /*Proper value in your case */;
    statusButton.frame = statusButtonFrame;
    [self.tabBar addSubview:statusButton];
}

-(void)surveyButtonDidSelect
{
    self.selectedIndex = 0 ;
}
-(void)statusButtonDidSelect
{
    self.selectedIndex = 1;
}

它对我有用,我没有问题.希望能帮助到你.
