1. 增加設置 info plist --> "View controller-based status bar appearance" 為 NO
2. 在AppDelegate.m 裡加上 [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    .......
    
    if (floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_6_1)
    {
         [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
    }
