You can dismiss your modal view controller and present it again setting the animation parameter to NO. 您可以关闭模态视图控制器，然后再次显示它，将animation参数设置为NO。 Another solution would be to embed your ViewController in a UINavigationController as its RootViewController (and present this one modally). 另一种解决方案是将ViewController作为RootViewController嵌入到UINavigationController中（并以模态形式呈现）。 When you have to reload your ViewController, simply use: 当您必须重新加载ViewController时，只需使用：
- (void)setViewControllers:(NSArray *)viewControllers animated:(BOOL)animated
on the navigationController with an array containing a new instance of your ViewController. 在navigationController上，包含一个包含ViewController的新实例的数组。
Anyway, are you really sure you can't simply reset all the contents of your UIViewController without "reloading" it from scratch? 无论如何，您真的确定不能简单地重设UIViewController的所有内容而不从头开始“重载”它吗？
