Question

我正在一个项目中工作，我需要在此实现标签栏控制器。我的标签栏背景颜色为黑色，我使用以下代码：

[[UITabBar appearance] setTintColor:[UIColor blackColor]];    
UITabBarItem *tabBarItem1 = [tabBarController.tabBar.items objectAtIndex:0];
UITabBarItem *tabBarItem2 = [tabBarController.tabBar.items objectAtIndex:1];
UITabBarItem *tabBarItem3 = [tabBarController.tabBar.items objectAtIndex:2];
UITabBarItem *tabBarItem4 = [tabBarController.tabBar.items objectAtIndex:3];    
[ tabBarItem1 setImageInsets:UIEdgeInsetsMake(2,0,-2,0)];
[ tabBarItem2 setImageInsets:UIEdgeInsetsMake(2,0,-2,0)];
[ tabBarItem3 setImageInsets:UIEdgeInsetsMake(2,0,-2,0)];
[ tabBarItem4 setImageInsets:UIEdgeInsetsMake(2,0,-2,0)];

tabBarItem1.title=@"Home";
tabBarItem2.title=@"Connect";
tabBarItem3.title=@"About";
tabBarItem4.title=@"Settings";


[[UITabBarItem appearance] setTitleTextAttributes:
 [NSDictionary dictionaryWithObjectsAndKeys:
  [UIColor colorWithRed:139.0/255.0 green:189.0/255.0 blue:208.0 alpha:255.0], UITextAttributeTextColor,
  [UIFont fontWithName:@"Arial" size:0.0], UITextAttributeFont,
  nil] forState:UIControlStateNormal];

[[UITabBarItem appearance] setTitleTextAttributes:
 [NSDictionary dictionaryWithObjectsAndKeys:
  [UIColor whiteColor], UITextAttributeTextColor,
  [UIFont fontWithName:@"Arial" size:0.0], UITextAttributeFont,
  nil] forState:UIControlStateSelected];

[tabBarItem1 setFinishedSelectedImage:[self imageWithImage:[UIImage imageNamed:@"home_icon_selected.png"] scaledToSize:CGSizeMake(24, 18)] withFinishedUnselectedImage:[self imageWithImage:[UIImage imageNamed:@"home_icon.png"] scaledToSize:CGSizeMake(24, 18)]];

[tabBarItem2 setFinishedSelectedImage:[self imageWithImage:[UIImage imageNamed:@"connect_icon_selected.png"] scaledToSize:CGSizeMake(24, 18)] withFinishedUnselectedImage:[self imageWithImage:[UIImage imageNamed:@"connect_icon.png"] scaledToSize:CGSizeMake(24, 18)]];

[tabBarItem3 setFinishedSelectedImage:[self imageWithImage:[UIImage imageNamed:@"about_icon_selected.png"] scaledToSize:CGSizeMake(24, 18)] withFinishedUnselectedImage:[self imageWithImage:[UIImage imageNamed:@"about_icon.png"] scaledToSize:CGSizeMake(24, 18)]];

[tabBarItem4 setFinishedSelectedImage:[self imageWithImage:[UIImage imageNamed:@"settings_icon_selected.png"] scaledToSize:CGSizeMake(24, 18)] withFinishedUnselectedImage:[self imageWithImage:[UIImage imageNamed:@"settings_icon.png"] scaledToSize:CGSizeMake(24, 18)]];


self.tabBarController.tabBar.tintColor = [UIColor whiteColor];

在ios7中工作正常，但在ios6中没有反映出这一行。在ios6中是否还有其他我需要实现的东西或者我对标签栏属性的任何遗漏？任何帮助将不胜感激。

他们在iOS 7中改变了很多颜色。阅读Apple的人机界面指南：https://developer.apple.com/library/ios/documentation/userexperience/conceptual/MobileHIG/index.html

以下是代码：

//check if this is not iOS 7
if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_6_1) {
//your code above except last line
//Tint is background in iOS 6 but text color in iOS 7
self.tabBarController.tabBar.tintColor = [UIColor blackColor];
}else{
//your code above
}

标签栏背景颜色在ios6中没有变化
