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:
// 状态栏(statusbar)
CGRect rectStatus = [[UIApplication sharedApplication] statusBarFrame];
NSLog(@"status width - %f", rectStatus.size.width); // 宽度
NSLog(@"status height - %f", rectStatus.size.height); // 高度
// 导航栏(navigationbar)
CGRect rectNav = self.navigationController.navigationBar.frame;
NSLog(@"nav width - %f", rectNav.size.width); // 宽度
NSLog(@"nav height - %f", rectNav.size.height); // 高度
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
