objective-c – UITabbarItem BadgeValue文本颜色

我的应用程序中存在问题.我在UITabBar的其中一个标签上设置了徽章值.徽章值正确为红色,徽章值周围的圆圈正确为白色.问题是,文本的颜色是灰色的(160,160,160).它与普通状态tabbaritem文本的颜色相同,但我在应用程序代码中没有设置此颜色,我不知道这种颜色来自何处.
几个星期以来,我在整个网络中搜索了这个问题,但我找不到任何解决方案.我到处找到的唯一答案是,无法更改徽章值文本的颜色.但如果不可能,为什么我的应用程序会改变它？
我希望,有人可以帮我解决这个问题……

编辑02.11.2012 – 代码

创建TabBarController：

#import "ExtendedTabBarController.h"
#import "configuration.h"

@implementation ExtendedTabBarController

- (void)viewDidLoad {
    [super viewDidLoad];
    [[UITabBarItem appearance] settitleTextAttributes:[NSDictionary DictionaryWithObjectsAndKeys: [UIColor colorWithRed:207.0/255.0 green:70.0/255.0 blue:61.0/255.0 alpha:1],UITextAttributeTextColor,[UIFont fontWithName:@"KievitPro-Regular" size:10.0],UITextAttributeFont,nil] forState:UIControlStateSELEcted];

    [[UITabBarItem appearance] settitleTextAttributes:[NSDictionary DictionaryWithObjectsAndKeys: [UIColor colorWithRed:255.0/255.0 green:255.0/255.0 blue:255.0/255.0 alpha:1],nil] forState:UIControlStateNormal];

    [self.tabBar sizeToFit];

    UIView *tabbarBACkgroundColorView = [[UIView alloc] initWithFrame:CGRectMake(0.0,self.view.bounds.size.width,49)];
    [tabbarBACkgroundColorView setBACkgroundColor:[UIColor colorWithRed:233.0/255.0 green:233.0/255.0 blue:233.0/255.0 alpha:1]];
    [self.tabBar insertSubview:tabbarBACkgroundColorView aTindex:0];
}

- (void)viewDidUnload {
    [super viewDidUnload];
}

- (void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];
}


- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    return UIInterfaceOrientationIsPor@R_673_9829@t(interfaceOrientation); // only por@R_673_9829@t orientation

}

/**
 *  orientation for iOS6
 **/
-(NSUInteger)supportedInterfaceOrientations{
    return UIInterfaceOrientationMaskPor@R_673_9829@t;
}

@end

在AppDelegate中调用：

ExtendedTabBarController *tabBarController = [[ExtendedTabBarController alloc] init];
[self setTabBarController:tabBarController];
[[UITabBar appearance] setBACkgroundImage:[UIImage imagenamed:@"menu_bg"]];

// code for initialize View- and NavigationControllers...

self.tabBarController.viewControllers = @[highlightsNavigationController,categoryNavigationController,searchNavigationController,favoritesNavigationController,imprintNavigationController];

self.window.rootViewController = self.tabBarController;

[[UITabBar appearance] setSELEctionInDicatorImage:[[UIImage alloc] init]];

设置徽章值：

int viewCount = 0;
NSUserDefaults * defs = [NSUserDefaults standardUserDefaults];
NSDictionary * Dict = [defs DictionaryRepresentation];
for (id key in Dict) {
    if([key rangeOfString:@"_highlighted"].LOCATIOn != NsnotFound && [[[Dict objectForKey:key] objectATindex:0] isEqualToString:@"YES"]) {
        viewCount++;
    }
}
UITabBarItem *tbi = (UITabBarItem *)[self.tabBarController.tabBar.items objectATindex:3];
if(viewCount <= 0) {
    tbi.badgeValue = nil;
} else {
    tbi.badgeValue = nil;
    tbi.badgeValue = [NSString StringWithFormat:@"%d",viewCount];
}

覆盖UILabel的代码：

// -- file: UILabel+VerticalAlign.h
#pragma mark VerticalAlign
@interface UILabel (VerticalAlign)
- (void)alignTop;
- (void)alignBottom;
- (void)awakeFromNib;
-(id)initWithFrame:(CGRect)frame;
@end


#import "UILabel+VerticalAlign.h"

// -- file: UILabel+VerticalAlign.m
@implementation UILabel (VerticalAlign)
- (void)alignTop {
    CGSize fontSize = [self.text sizeWithFont:self.font];
    double finalHeight = fontSize.height * self.numberOfLines;
    double finalWidth = self.frame.size.width;    //expected width of label
    CGSize theStringSize = [self.text sizeWithFont:self.font cons@R_673_9829@nedToSize:CGSizeMake(finalWidth,finalHeight) lineBreakmode:self.lineBreakmode];
    int newLinesToPad = (finalHeight  - theStringSize.height) / fontSize.height;
    for(int i=0; i<newLinesToPad; i++)
        self.text = [self.text StringByAppendingString:@"\n "];
}

- (void)alignBottom {
    CGSize fontSize = [self.text sizeWithFont:self.font];
    double finalHeight = fontSize.height * self.numberOfLines;
    double finalWidth = self.frame.size.width;    //expected width of label
    CGSize theStringSize = [self.text sizeWithFont:self.font cons@R_673_9829@nedToSize:CGSizeMake(finalWidth,finalHeight) lineBreakmode:self.lineBreakmode];
    int newLinesToPad = (finalHeight  - theStringSize.height) / fontSize.height;
    for(int i=0; i<newLinesToPad; i++)
        self.text = [NSString StringWithFormat:@" \n%@",self.text];
}
- (void)awakeFromNib
{
    [super awakeFromNib];
    [self setFont:[UIFont fontWithName:@"KievitPro-Regular" size:12.0]];
}

-(id)initWithFrame:(CGRect)frame
{
    id result = [super initWithFrame:frame];
    if (result) {
        [self setFont:[UIFont fontWithName:@"KievitPro-Regular" size:12.0]];
    }
    return result;
}

@end

- (void)awakeFromNib
{
    [super awakeFromNib];
    [self setFont:[UIFont fontWithName:@"KievitPro-Regular" size:12.0]];
}

-(id)initWithFrame:(CGRect)frame
{
    id result = [super initWithFrame:frame];
    if (result) {
        [self setFont:[UIFont fontWithName:@"KievitPro-Regular" size:12.0]];
    }
    return result;
}
