在没有XIB文件的情况下,在loadView方法(在UIViewController中)计算视图大小的最佳实践是什么?
这是我的解决方案:
- (void)loadView { //Calculate Screensize BOOL statusBarHidden = [[UIApplication sharedApplication] isstatusBarHidden ]; BOOL navigationBarHidden = [self.navigationController isNavigationBarHidden]; BOOL tabBarHidden = [self.tabBarController.tabBar isHidden]; CGRect frame = [[UIScreen mainScreen] bounds]; if (!statusBarHidden) { frame.size.height -= [[UIApplication sharedApplication] statusBarFrame].size.height; } if (!navigationBarHidden) { frame.size.height -= self.navigationController.navigationBar.frame.size.height; } if (!tabBarHidden) { frame.size.height -= self.tabBarController.tabBar.frame.size.height; } UIView *v = [[UIView alloc] initWithFrame: frame]; [v setBackgroundColor: [UIColor whiteColor] ]; [v setAutoresizingMask: UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight ]; [self setView: v ]; [v release]; }
这段代码好吗,还是我应该编辑一些东西?
解决方法
文档建议使用[[UIScreen mainScreen] applicationFrame]获取没有状态栏的屏幕边界
