我用来调整元素的两种方法是这些,它们尚未完成,因为我目前正在为新的iphone修复它们.

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([segue.identifier isEqualToString:@"MoreOptions"]) {
UINavigationController *navigationController = segue.destinationViewController;
MoreOptionsViewController *controller = (MoreOptionsViewController *)navigationController.topViewController;
controller.delegate = self;
} else if ([segue.identifier isEqualToString:@"FullStoryView"]) {

所有这一切都很好,但我想尝试更好地理解代码.我不明白的是,我必须通过从navigationController.topViewController中获取它来获取对MoreOptionsViewController的引用,而不是简单地从segue.destinationViewController获取它,就像我在第二个if条件中那样.是因为我将当前视图控制器(self)设置为委托吗?同样,我不是试图解决问题,而是试图更好地了解正在发生的事情.
有谁知道导航栏背景的iOS图像分辨率?我已经在Apple的自定义图标和图像创建指南页面上找到了几乎所有其他元素的分辨率,但我似乎无法找到导航条背景图像(常规和视网膜)的像素大小要求.
我的目标是运行反应本机构建(ios 版本)。
