如何在iOS开发中切换新的视图控制器？

Question

我正在尝试编写一个IBAction来切换我的iPhone应用程序的视图控制器：

-(IBAction)changeToView2:(id)sender 
{
    if (self.view2 == nil)
    {
        view2 = [[UIViewController alloc] initWithNibName:@"View2Controller" bundle:[NSBundle mainBundle]];
    }
    self.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
    [self presentedViewController: view2 animated:YES];
}

但是，我收到一个构建错误，注意没有接口声明“presentViewController：animated：”。为什么呢？

将其更改为“presentViewController：animated：”会产生相同的错误。

Answer 1

该方法为presentViewController:animated:completion:，而不是present ed ViewController:animated:

Answer 2

而不是

[self presentedViewController: view2 animated:YES];

试

[self presentViewController: view2 animated:YES];

Answer 3

[self presentViewController:view2 animated:YES];

Answer 4

尝试使用您编辑的代码。我认为这对您有所帮助。

-(IBAction)changeToView2:(id)sender 
{
if (self.view2 == nil)
{
    view2 = [[UIViewController alloc] initWithNibName:@"View2Controller" bundle:nil];
}
self.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentedViewController: view2 animated:YES];
}
