1 一：在AppDelegate中统一定制导航栏风格 2 //设置导航栏颜色，标题字体和颜色，还有阴影效果 3 [[UINavigationBar appearance] setBarTintColor:[UIColor colorWithRed:26/255.0 green:154/255.0 blue:215/255.0 alpha:1.0]]; 4 [[UINavigationBar appearance] setTintColor:[UIColor whiteColor]]; 5 NSShadow *shadow = [[NSShadow alloc] init]; 6 shadow.shadowColor = [UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.8]; 7 shadow.shadowOffset = CGSizeMake(0, 1); 8 [[UINavigationBar appearance] setTitleTextAttributes: [NSDictionary dictionaryWithObjectsAndKeys: 9 [UIColor colorWithRed:245.0/255.0 green:245.0/255.0 blue:245.0/255.0 alpha:1.0], NSForegroundColorAttributeName, 10 shadow, NSShadowAttributeName, 11 [UIFont fontWithName:@"HelveticaNeue-CondensedBlack" size:20.0], NSFontAttributeName, nil]]; 12 //设置返回箭头为自定义图片 13 [[UINavigationBar appearance] setBackIndicatorImage:[UIImage imageNamed:@"返回箭头.png"]]; 14 [[UINavigationBar appearance] setBackIndicatorTransitionMaskImage:[UIImage imageNamed:@"返回箭头.png"]]; 15 二：在每个界面单独设置返回时字体的位置，可以放在当前页面的ViewDidLoad中 16 UIBarButtonItem *backItem=[[UIBarButtonItem alloc]init]; 17 backItem.title=@" 用户登录"; 18 self.navigationItem.backBarButtonItem = backItem;
