From Ray Wenderlich:

// Customize the title text for *all* UINavigationBars
[[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:@"Arial-Bold" size:0.0], 
        UITextAttributeFont, 
        nil]];

Or if you prefer with the object literal style:

[[UINavigationBar appearance] setTitleTextAttributes:@{
    UITextAttributeTextColor: [UIColor colorWithRed:255.0/255.0 green:255.0/255.0 blue:255.0/255.0 alpha:1.0],
    UITextAttributeTextShadowColor: [UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.8],
    UITextAttributeTextShadowOffset: [NSValue valueWithUIOffset:UIOffsetMake(0, -1)],
    UITextAttributeFont: [UIFont fontWithName:@"Arial-Bold" size:0.0],
}];

Edit for iOS 7 and following

UITextAttributes are deprecate as iOS 7 you can use the following :

NSShadow *shadow = [[NSShadow alloc] init];
shadow.shadowColor = [UIColor colorWithWhite:.0f alpha:1.f];
shadow.shadowOffset = CGSizeMake(0, -1);

[[UINavigationBar appearance] setTitleTextAttributes:@{
     NSForegroundColorAttributeName: [UIColor whiteColor],
     NSShadowAttributeName: shadow,
     NSFontAttributeName: [UIFont fontWithName:@"Arial-Bold" size:15.0f]
     }];
