iOS状态栏设置样式

单独的一个页面

UIView *statusBarView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, WIDTH, 20)];
statusBarView.backgroundColor = [UIColor colorWithRed:36/255.0 green:58/255.0 blue:100/255.0 alpha:1];
[self.view addSubview:statusBarView];
[UIApplication sharedApplication].statusBarStyle = UIStatusBarStyleLightContent;

全局的

UIView *statusBarView = [[UIView alloc] initWithFrame:CGRectMake(0, -20, self.window.frame.size.width, 20)];
statusBarView.backgroundColor = [UIColor colorWithRed:36/255.0 green:58/255.0 blue:100/255.0 alpha:1];
[self.navigationController.navigationBar addSubview:statusBarView];
[UIApplication sharedApplication].statusBarStyle = UIStatusBarStyleLightContent;
[self.navigationController.navigationBar setBackgroundImage:[UIImage imageNamed:@"navigationBar"] forBarMetrics:UIBarMetricsDefault];
[self.navigationController.navigationBar setTitleTextAttributes:@{NSForegroundColorAttributeName:[UIColor whiteColor]}];
