我在iOS7上遇到导航栏项目文字颜色的问题。

一切都很好,直到我呈现一个viewcontroller,从这时起,所有导航栏项目的文本颜色都是Gray。你对这个问题有经验吗?

用于呈现VC的代码:

[passcodePopover presentPopoverFromRect:CGRectMake([UIScreen mainScreen].bounds.size.width/2 ,currentWindow.frame.size.height/2,1,1)
                                     inView:currentWindow
                   permittedArrowDirections:0 animated:NO];[passcodePopover presentPopoverFromRect:CGRectMake([UIScreen mainScreen].bounds.size.width/2 ,currentWindow.frame.size.height/2,1,1)
                                     inView:currentWindow
                   permittedArrowDirections:0 animated:NO];

//call the below code in ViewDidLoad /It works fine in iOS7

UILabel *navLabel = [[UILabel alloc] initWithFrame:CGRectMake(0,0, 320, 100)];
navLabel.backgroundColor = [UIColor clearColor];
navLabel.text = @"Event Details";
navLabel.textColor = [UIColor whiteColor];
navLabel.shadowOffset = CGSizeMake(0, -2);
[navLabel setFont:[UIFont boldSystemFontOfSize:16]];
navLabel.textAlignment = NSTextAlignmentCenter;
self.navigationItem.titleView = navLabel;

UILabel *label = [[UILabel alloc] initWithFrame:CGRectZero] ;
label.backgroundColor = [UIColor clearColor];
label.font = [UIFont boldSystemFontOfSize:20.0]; // font size
label.shadowColor = [UIColor colorWithWhite:0.0 alpha:0.5];
label.textAlignment = NSTextAlignmentCenter;

label.textColor = [UIColor yellowColor]; // change this color
self.navigationItem.titleView = label;
label.text = NSLocalizedString(@"Product Info.", @""); // lable name
[label sizeToFit];

[[UINavigationBar appearance] setTitleTextAttributes:
   [NSDictionary dictionaryWithObjectsAndKeys:[UIColor whiteColor],
   NSForegroundColorAttributeName,[UIColor whiteColor],
   NSForegroundColorAttributeName,[NSValue valueWithUIOffset:UIOffsetMake(0, -1)],
   NSForegroundColorAttributeName,[UIFont fontWithName:@"Arial-Bold" size:0.0],
   NSFontAttributeName,nil]];

在passcodePopover的viewdidLoad方法中,您将需要使用此代码。

self.navigationController.navigationBar.tintColor = [UIColor whiteColor];
NSDictionary *textTitleOptions = [NSDictionary dictionaryWithObjectsAndKeys:[UIColor whiteColor], NSForegroundColorAttributeName, nil];
[self.navigationController.navigationBar setTitleTextAttributes:textTitleOptions];

如果弹出窗口中没有navigationController,则必须稍微更改代码,也可能不想使用[UIColor whiteColor]。而是替换你自己选择的颜色。

在viewdidLoad函数中使用以下代码

  if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_6_1) {

        // Load resources for iOS 6.1 or earlier
         [[UINavigationBar appearance]setTintColor:NavigationColor];
    } else
     {
         [[UINavigationBar appearance]setTintColor:[UIColor whiteColor]]; // it set color of bar button item text 
    }

改为创建一个类别:

@implementation UINavigationBar (custom)
- (void)setCustomNavigationBar: (NSString *)_strTitle
{
    [self setBackgroundImage:[UIImage imageNamed:@"navigationbar"] forBarMetrics:UIBarMetricsDefault];

    UILabel *_lblTitle = [[UILabel alloc]initWithFrame:CGRectMake(0, 0, 100, 30)];
    _lblTitle.text = _strTitle;
    _lblTitle.textAlignment = NSTextAlignmentCenter;
    [_lblTitle setBackgroundColor:[UIColor clearColor]];
    [_lblTitle setFont:[UIFont fontWithName:kAppFontBold size:kAppFontBoldSize]];
    [_lblTitle setTextColor:[UIColor navigationBarColor]];
    [[self topItem] setTitleView:_lblTitle];
}

kAppFontBoldkAppFontBoldSize是宏。

你可以用它。它可能对你有所帮助..在这里,我为两个州设置了font and text color

[barItemForIndex setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
                                                    [UIFont systemFontOfSize:Tabbar_Item_Font_Size], NSFontAttributeName,
                                                    [UIColor darkGrayColor], NSForegroundColorAttributeName,
                                                    nil] forState:UIControlStateNormal];
[barItemForIndex setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
                                                    [UIFont systemFontOfSize:Tabbar_Item_Font_Size], NSFontAttributeName,
                                                    [UIColor whiteColor], NSForegroundColorAttributeName,
                                                    nil] forState:UIControlStateSelected];

注意: setTitleTextAttributes:方法仅适用于ios5.0 +。
