[self.navigationController.navigationBar setTitleTextAttributes:@{
NSForegroundColorAttributeName:[UIColor whiteColor],
NSFontAttributeName:NAVIGATIONBAR_TITLE_FONT
}];
                                                                                                           
                                                                                                                    
#关于状态栏颜色
//在plist文件里添加  View controller-based status bar appearance == NO 默认是YES
[UIApplication sharedApplication].statusBarStyle = UIStatusBarStyleLightContent;
