自定义UITabBar项
自定义UITabBar项
提问于 2014-05-02 06:42:34
对于每个TabBar项目，我都有一个简单的设计：
- 背景颜色： firstTab宽度=屏幕(左)的1/3高度= tabBarHeight secondTab宽度=屏幕(中间)的1/3高度= tabBarHeight thirdTab宽度=屏幕的1/3 (右)高度= tabBarHeight
- 以表格项的水平和垂直为中心的标题。
我发现了关于如何更改整个选项卡背景的不同文章，如下所示：
UIImage* tabBarBackground = [UIImage imageNamed:@"tabbar.png"];
[[UITabBar appearance] setBackgroundImage:tabBarBackground];我找到了每一张图片，但这并不能填满整个标签：
[[tabBarController.tabBar.items objectAtIndex:0] setFinishedSelectedImage:[UIImage imageNamed:@"tabbaritem.png"] withFinishedUnselectedImage:[UIImage imageNamed:@"tabbaritem.png"]];回答 3

UITabBarItem *tab1 = [[UITabBarItem alloc] init];
tab1.image = [[UIImage imageNamed:@"home_icon.png"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
tab1.selectedImage = [[UIImage imageNamed:@"home_icon_selected.png"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];Stack Overflow用户

更好的方法是创建一个subClass of UITabBarController
到changeBackGround颜色，
self.tabBar.backgroundColor = [UIColor redColor];对于tintColor
self.tabBar.barTintColor = [UIColor greenColor];在“init”方法本身。
For seetTitle
创建一个数组
//title
titleArray = [[NSMutableArray alloc]initWithObjects:@"Title 1",@"Title 2",@"Title 3", nil];
//image array
NSArray *imageArray = @[image1,image2,image3];
for (int i = 0; i< imageArray.count; i++)
{
UINavigationController *nav = [self.viewControllers objectAtIndex:i];
[nav.tabBarItem setTitle:[titleArray objectAtIndex:i]];
//You can adjust title position by adjust `titlePositionAdjustment`
nav.tabBarItem.titlePositionAdjustment = UIOffsetMake(0, -15);
//for add image on tabbr item for ios 7
nav.tabBarItem.image = [[imageArray objectAtIndex:i]imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
}在ios 6上添加图像
nav.tabBarItem.image = [imageArray objectAtIndex:i];在ios 7中检索选定的图像
nav.tabBarItem.image = [imageArray objectAtIndex:i];适用于ios 6
nav.tabBarItem.selectedImage = [imageArraySelected objectAtIndex:i];调整图像EdgeInset
nav.tabBarItem.imageInsets = UIEdgeInsetsMake(14,0.0, -14,-2);用于添加标题Attibutes
[nav.tabBarItem setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColor whiteColor],NSForegroundColorAttributeName,[UIFont fontWithName:@"Helvetica-Bold" size:14.0f],NSFontAttributeName, nil] forState:UIControlStateNormal];Stack Overflow用户

你可以这样做
UIImage *tabBackground = [[UIImage imageNamed:@"tabbg.png"]
resizableImageWithCapInsets:UIEdgeInsetsMake(0, 0, 0, 0)];
[[UITabBar appearance] setBackgroundImage:tabBackground];
UITabBarItem *tabBarItem1 = [tabbar.items objectAtIndex:0];
UITabBarItem *tabBarItem2 = [tabbar.items objectAtIndex:1];
UITabBarItem *tabBarItem3 = [tabbar.items objectAtIndex:2];
tabBarItem1.title = @"one";
tabBarItem2.title = @"Two";
tabBarItem3.title = @"Three";
[tabbar setSelectedItem:[tabbar.items objectAtIndex:0]];
[tabBarItem1 setFinishedSelectedImage:[UIImage imageNamed:@"one.png"] withFinishedUnselectedImage:[UIImage imageNamed:@"one_active.png"]];
[tabBarItem2 setFinishedSelectedImage:[UIImage imageNamed:@"Two".png"] withFinishedUnselectedImage:[UIImage imageNamed:@"Two_active.png"]];
[tabBarItem3 setFinishedSelectedImage:[UIImage imageNamed:@"Three.png"] withFinishedUnselectedImage:[UIImage imageNamed:@"Three_active.png"]];页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
