objective-c - 如何以编程方式移动到另一个 UIViewController？

Question

我目前正在 CurrentViewController 中执行一个方法，当我到达时我想移动到我的 FirstViewController(这是我想移动到的 ViewController 的实际名称)当前正在执行的方法结束

CurrentViewController.m

-(void)methodExecutingOnCurrentViewController
{
    //some code..

    // what method do I call in order to load and move to my FirstViewController at this point?

    // do I first initialize an instance of the ViewController I want to move to?
    UIViewController *firstViewController = [[FirstViewController alloc] init];


    // but now how do I actually move to this instance I've just created? 
    // I couldn't find the appropriate method in the class reference documentation

}

看看 - (void)presentModalViewController:(UIViewController *)modalViewController animated:(BOOL)animated Doc .

还有许多其他方法可以完成您正在寻找的东西，您使用的是导航 Controller 吗？然后 - (void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated 就是你想要的。您也可以将该 Controller 的 View 作为 subview 添加到当前的 viewController。
