UITabbarItem BadgeValue文本颜色

Question

我的应用程序出现问题。我在UITabBar的其中一个选项卡上设置了一个徽章值。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）。它与正常状态下的tabbaritem文字是相同的颜色，但我在应用程序代码中没有设置此颜色，我不知道此颜色来自哪里。 自从周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。我在处处找到的唯一答案是，无法更改徽章值文本的颜色。但如果这是不可能的，为什么它在我的应用程序中更改？ 我希望有人能帮助我这个问题......

TabBarController的创作：

#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], UITextAttributeTextColor, [UIFont fontWithName:@"KievitPro-Regular" size:10.0], UITextAttributeFont, nil] forState:UIControlStateNormal]; 

    [self.tabBar sizeToFit]; 

    UIView *tabbarBackgroundColorView = [[UIView alloc] initWithFrame:CGRectMake(0.0, 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 UIInterfaceOrientationIsPortrait(interfaceOrientation); // only portrait orientation 

} 

/** 
* orientation for iOS6 
**/ 
-(NSUInteger)supportedInterfaceOrientations{ 
    return UIInterfaceOrientationMaskPortrait; 
} 

@end 

通话中的AppDelegate：

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]; 
} 

代码覆盖的UILabel：

// -- 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 constrainedToSize: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 constrainedToSize: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 

Answer 1

我发现我自己对我的问题的解决方案：

我必须删除从覆盖的UILabel以下行：

- (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; 
} 

也许有人可以解释我，为什么这行代码会更改徽章值的文本颜色，然后才能关闭此帖子？

Answer 2

而不是使用一个类别设置默认的UILabel字体，使用UILabel的外观的方法来设置字体：

[[UILabel appearance] setFont:[UIFont fontWithName:@"KievitPro-Regular" size:12.0]]; 

当我这个测试的徽章文本表现为正常的白色。
