iOS:推送相同的视图控制器 [英] iOS: Push same view controller

问题描述

如果我有一个按钮，并且希望使用同一控制器为默认的"UI页面幻灯片"设置动画，那么当单击下一个按钮"时如何实现?我以为这样可以用，但是不可以.

If I have a button and I want to animate the default "UI Page Slide" with the same controller, how would I make that happen when the "nextbutton" is clicked? I thought this would work, but it doesn't.

- (IBAction)NextButton:(id)sender
{
    [self.navigationController pushViewController:self animated:YES];
    NSInteger CurrentQuestionNumber = [QuestionNumber intValue];
    NSInteger NewQuestionNumber = CurrentQuestionNumber + 1;
    QuestionNumber = [NSString stringWithFormat:@"%d", NewQuestionNumber];
    QuestionNumberLabel.text = QuestionNumber;
    QuestionLabel.text = [QuestionsList objectForKey:QuestionNumber];
}

推荐答案

您无需实例化self，而是需要实例化同一类的新实例，并将其实例化为 self 的替代品.然后，您可以在 -viewDidLoad 方法中获取相关数据并将其解析到接口中.

Instead of pushing self, you need to instantiate a new instance of the same class, and push that in replace of self. You can then get the relevant data and parse it into the interface in your -viewDidLoad method.

SameClassAsSelf *new_self = [[SameClassAsSelf alloc] init...];
new_self.questionNumber = QuestionNumber;
new_self.questionsList = QuestionsList; //if needed
[self pushViewController:new_self animated:YES];
[new_self release];
