iPhone开发当中，有时需要获取状态栏和导航栏高度、宽度信息，方便布局其他控件。下面介绍一下如何获取这些信息：
- CGRect rectStatus = [[UIApplication sharedApplication] statusBarFrame];
- NSLog(@"status width - %f", rectStatus.size.width);
- NSLog(@"status height - %f", rectStatus.size.height);
-
- CGRect rectNav = self.navigationController.navigationBar.frame;
- NSLog(@"nav width - %f", rectNav.size.width);
- NSLog(@"nav height - %f", rectNav.size.height);
打印结果如下：
- 2015-01-14 13:22:22.206 app_name[226:60b] status width - 320.000000
- 2015-01-14 13:22:22.209 app_name[226:60b] status height - 20.000000
- 2015-01-14 13:22:22.210 app_name[226:60b] nav width - 320.000000
- 2015-01-14 13:22:22.211 app_name[226:60b] nav height - 44.000000
