[英]Tab Bar with Large Icons
我想知道是否有一种方法可以仅使用大图标来完成选项卡栏,我在下面附加了图像以供参考。 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。
这是我的解决方案,我创建了一个类,它是UITabBarController
的子类。
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;
}
它为我工作,我没问题。 希望能帮助到你。
要添加到@limon的答案中,如果您想更改自定义UITabBar的高度,我从另一个SO答案中找到了,抱歉,不记得Web链接参考了,下面的代码起到了作用并将其锁定在底部,在哪里我用@limon的代码发现UITabBar的位置与他的代码不在盒子底部齐平:
override func viewWillLayoutSubviews() {
//UITabBar Height
var tabFrame: CGRect = self.tabBar.frame
tabFrame.size.height = 75
tabFrame.origin.y = self.view.frame.size.height - 75
self.tabBar.frame = tabFrame
}
显然,您想从limon的答案中删除类似的代码,或者也许将其整个代码段移至viewWillLayoutSubviews
我没有尝试过,我在viewDidLoad
调用了他的代码
iPhone 5 / iPhone 4的选项卡栏中图像的最大尺寸为96 x 64,因此您在此处有限度而不会自行滚动。 尽管在您的示例图像中,这些可能适合约束。
