iphone - 禁止点击背景 UIViewController

Question

我在点击 UITableViewCell 时加载了 ABPeoplePickerNavigationController。

self.peoplePicker = [[ABPeoplePickerNavigationController alloc] init];
self.peoplePicker.peoplePickerDelegate = self;
[self.peoplePicker setDelegate:self];
self.peoplePicker.modalPresentationStyle = UIModalPresentationFormSheet;
[self presentViewController:self.peoplePicker animated:YES completion:nil];

When the picker is presented as UIModalPresentationFormSheet, I want to disable the UIViewController behind it.为此，我可以在呈现选择器时加载一个透明 View ，并在选择器被关闭时将其关闭。所以在 viewcontroller 上点击将不起作用。我想知道是否有另一种方法可以做到这一点，我不需要创建新的 UIView 并加载/关闭它。

在呈现 Picker View 之前和关闭 Picker View 之后，您可以在 ViewController 的 View 上setUserInteractionEnabled 属性。
