本文详细介绍了如何在AppDelegate中设置iOS应用的导航栏颜色、状态栏样式以及标题文字颜色，实现应用的整体视觉风格调整。

在AppDelegate中设置

#define SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(v)  ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending)

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // Override point for customization after application launch.
    if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7.0")) {
        [[UINavigationBar appearance] setBarTintColor:[UIColor colorWithRed:34/255.0 green:166/255.0 blue:236/255.0 alpha:1]];
        [[UINavigationBar appearance] setTintColor:[UIColor whiteColor]];
    }
    [[UINavigationBar appearance] setTitleTextAttributes:@{NSForegroundColorAttributeName : [UIColor whiteColor]}];
    
    // Status bar white
    [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
    return YES;
}
