如何在iOS 5中关闭popovers？ [英] How to dismiss popovers in iOS 5?

问题描述

我在iPad的主屏幕中有一个 PatientTableViewController ，其中有一个用于添加新病人的按钮。

I have a PatientTableViewController in the master side of the iPad that has a button for Adding a new patient. It transitions to this NewPatientViewController via a popover segue.

在 NewPatientViewController 中，我将转换到 NewPatientViewController 具有委派回 PatientTableViewController 的完成按钮：

In the NewPatientViewController I have a Done button that delegates back to the PatientTableViewController:

- (void)newPatientViewController:(NewPatientViewController *)sender withZipCode:(NSNumber *)zipCode andFirstName:(NSString *)firstName andLastName:(NSString *)lastName
{
    [self dismissViewControllerAnimated:YES completion:NULL];
    [self dismissModalViewControllerAnimated:YES];
    [sender dismissModalViewControllerAnimated:YES];
    [sender dismissViewControllerAnimated:YES completion:NULL];
}

上面尝试的方法都没有。但是，如果我使用模态segue，一切工作正常。 Wat？

None of the methods I tried above work. However, if I use a Modal segue, everything works fine. Wat?

推荐答案

最后，借助这个帖子

基本上，你需要一个变量跟踪

Basically, you need to have a variable keep track of the segue (which you need to cast into a UIStoryboardPopoverSegue) and little more weirdness.
