我可以从另一个模态视图控制器中推送一个模态视图控制器吗? [英] Can I push a modal view controller from within another modal view controller?

问题描述

我有一个 rootViewController，它一度显示一个 peoplePickerNavigationController.当我的用户选择特定的联系人属性时，我试图推送第二个视图控制器，如下所示:

I've got a rootViewController that, at one point, displays a peoplePickerNavigationController. I'm trying to push a second view controller when my user selects a specific contact property, like so:

-(BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)picker shouldContinueAfterSelectingPerson:(ABPersonRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier {
RuleBuilder *ruleBuilder = [[RuleBuilder alloc] initWithNibName:@"RuleBuilder" bundle:nil];
[self pushModalViewController:ruleBuilder animated:YES];
[ruleBuilder release];
return NO;
}

这编译得很好，但是当我在模拟器中运行代码并通过 peoplePicker 运行时，当我选择联系人属性时没有任何反应.一时兴起，我添加了一个 [self deniedModalViewControllerAnimated:YES];就在 [ruleBuilder 发布] 之前；这会关闭 peoplePicker，但对我丢失的 ruleBuilder 没有影响.

This compiles just fine, but when I run the code in the simulator and run through the peoplePicker, nothing happens when I select a contact property. On a whim, I added a [self dismissModalViewControllerAnimated:YES]; just before [ruleBuilder release]; and that dismisses the peoplePicker, but otherwise has no effect on my missing ruleBuilder.

有什么想法吗?

推荐答案

找到解决方案:

[picker pushModalViewController:ruleBuilder animated:YES];
