iphone - 选择时如何更改 UITabBarItem 标题的颜色

Question

我的环境，

iOS6
Xcode 4.5.1

我想在选中时更改 UITabBarItem 标题的颜色。

我将 CustomUITabBarItem 用于 UITabBarItem。- customUITabBarItem.m

@implementation customUITabBarItem

@synthesize customHighlightedImage;

-(UIImage *) selectedImage
{
    return self.customHighlightedImage;
}

- (void) dealloc
{
    [customHighlightedImage release];
    customHighlightedImage=nil;
    [super dealloc];
}

@end

ViewController.m

#import "FirstViewController.h"
#import "customUITabBarItem.h"


@interface FirstViewController ()

@end

@implementation FirstViewController

- (void)viewDidLoad
{   
    [super viewDidLoad];
    CustomUITabBarItem *tabItem = [[customUITabBarItem alloc] initWithTitle:@"first" image:[UIImage imageNamed:@"first.png"] tag:0]; 
    tabItem.customHighlightedImage = [UIImage imageNamed:@"first_selected.png"];
    self.tabBarItem = tabItem;
    [tabItem release];
    tabItem = nil;
}   

如何改变颜色？

Answer 1

 [self.tabBarItem setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
                                            [UIFont fontWithName:@"AmericanTypewriter" size:20.0f], UITextAttributeFont,
                                            [UIColor blackColor], UITextAttributeTextColor,
                                            [UIColor grayColor],        
                                            nil]];

请确保这仅适用于 iOS 5.0 或更高版本。
