Customizing Title bar in iOS 5

In iOS 5,customizing title bar with backgroundImage is pretty simple:

    [[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:@"image.png"] forBarMetrics:UIBarMetricsDefault];

But for the text font and color, it requires a little bit more work:      

    [[UINavigationBar appearance] setTitleTextAttributes:

    [NSDictionary dictionaryWithObjectsAndKeys:

    [UIColor colorWithRed:255.0/255.0 green:255.0/255.0 blue:255.0/255.0 alpha:1.0],

    UITextAttributeTextColor,

    [UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.8],

    UITextAttributeTextShadowColor,

    [NSValue valueWithUIOffset:UIOffsetMake(0, -1)],

    UITextAttributeTextShadowOffset,

    [UIFont fontWithName:@"STHeitiSC-Medium" size:0.0],

    UITextAttributeFont, nil]];
