Question

我在这里遇到了一些问题。当我在主视图中单击我的跟踪按钮时，如果显示跟踪信息，则按钮会将我带到新视图。我遇到的一个问题是，当它移动到新视图时，任何标签都开始变小并且动画变为正常大小。我不确定我是否已经正确地解释了它，但是当我设置它时，视图是动画的。我将在下面附上代码。

感谢。

- (IBAction)ordertrack {
    UIStoryboard *sb = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
    UIViewController *vc = [sb instantiateViewControllerWithIdentifier:@"track1"];
    [self presentViewController:vc animated:NO completion:NULL];
}

更新：

我仍然没有任何解决方案可以工作，我已经附上下面的gif来显示问题，你会看到后退按钮会调整大小。

Answer 1

@ChikabuZ说实话。（投票）

animated上的presentViewController:animated:completion:参数控制新视图控制器是滑动到屏幕上还是仅显示。它对新视图控制器出现后的作用没有影响。

如果新的＆＃34; track1＆＃34;视图控制器在其设置代码中有动画，这些动画仍然会出现。您需要构建自己的机制来告诉它不要动画。（也许可以向dontAnimateInitialDisplay VC添加track1属性，并编写代码，如果dontAnimateInitialDisplay为真，则会跳过动画。然后您将上面的代码更改为：

- (IBAction)ordertrack {
    UIStoryboard *sb = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
    //Cast "vc" to the correct type so we have access to the 
    //dontAnimateInitialDisplay property
    Track1VC *vc = (Track1VC *)
      [sb instantiateViewControllerWithIdentifier:@"track1"];
    vc.dontAnimateInitialDisplay = TRUE;
    [self presentViewController:vc animated:NO completion:NULL];
}

Answer 2

动画可以在您提供的track1视图控制器中实现。例如，在viewDidLoad / viewDidAppear。

中

检查[UIView animateWithDuration: ...

iOS presentViewController关闭时动画
