Question

我正在尝试使用下面的代码设置导航栏文本的样式，但我无法使其工作。我之前有代码，但Xcode一直告诉我它已经被iOS 7弃用了。关于如何让它工作的任何建议？

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.

    [self.navigationController setNavigationBarHidden:NO];

    //SET COLORS AND FONTS
    UIColor* mainColor = [UIColor colorWithRed:28.0/255 green:158.0/255 blue:121.0/255 alpha:1.0f];
    UIColor* darkColor = [UIColor colorWithRed:7.0/255 green:61.0/255 blue:48.0/255 alpha:1.0f];

    NSString* fontName = @"Avenir-Book";
    NSString* boldFontName = @"Avenir-Black";

    //[self styleNavigationBarWithFontName:boldFontName];

    self.title = @"Walk With Me";

    UINavigationBar* navAppearance = [UINavigationBar appearance];

    [navAppearance setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
                                           [UIColor redColor], NSForegroundColorAttributeName,
                                           [UIFont fontWithName:boldFontName size:18.0f], NSFontAttributeName,
                                           [NSValue valueWithCGSize:CGSizeMake(0.0, 0.0)], NSShadowAttributeName,
                                           nil]];
}

以下是导航栏标题{ - 1}}的示例代码段 -

altering the font style

将图片用作导航栏标题

NSShadow *shadow = [[NSShadow alloc] init];
shadow.shadowColor = [UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.8];
test.shadowOffset = CGSizeMake(0, 1);
[[UINavigationBar appearance] setTitleTextAttributes: [NSDictionary dictionaryWithObjectsAndKeys:
                                                       [UIColor colorWithRed:245.0/255.0 green:245.0/255.0 blue:245.0/255.0 alpha:1.0], NSForegroundColorAttributeName,
                                                       shadow, NSShadowAttributeName,
                                                       [UIFont fontWithName:@"HelveticaNeue-CondensedBlack" size:21.0], NSFontAttributeName, nil]];

     NSDictionary *titleTextAttributes=@{                                          
                 NSForegroundColorAttributeName: [UIColor redColor],                                                                                                  

    NSFontAttributeName: [UIFont systemFontOfSize:17.0],};

 UINavigationController * objView=(UINavigationController *)[UIApplication sharedApplication].keyWindow.rootViewController;    
    objView.navigationBar.titleTextAttributes = titleTextAttributes;

如何在iOS 7的导航栏中设置文本样式？
