[[UINavigationBar appearance] setBarTintColor:[UIColor colorWithRed:0 green:0 blue:0 alpha:1]];

[[UINavigationBar appearance] setBarTintColor:UIColorFromRGB(0x067AB5)];

设置导航文字颜色

[[UINavigationBar appearance] setTintColor:[UIColor whiteColor]];

设置导航背景

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

设置多个导航按钮

UIBarButtonItem *shareItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAction target:self action:nil];

UIBarButtonItem *cameraItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCamera target:self action:nil];

NSArray *actionButtonItems = @[shareItem, cameraItem];

self.navigationItem.rightBarButtonItems = actionButtonItems;

设置导航字体

NSShadow *shadow = [[NSShadow alloc] init];

shadow.shadowColor = [UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.8];

shadow.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]];
