为什么presentModalViewController无法正常工作？

Question

我在一个视图中呈现一个模态控制器，在我解除视图后我想呈现另一个modalView但代码不工作，我有一个委托方法，当我按下第一个模态视图中的按钮时被调用我有代码。

在parentView内部为firstview委托的方法：

    -(void)newMessageModalView:(NewMessageModalView *)controller didFinishSelecting:(int)selectedChannel{
                [self dismissModalViewControllerAnimated:YES];
           SecondView * detailView = [[SecondView alloc] initWithNibName:@"SecondView" bundle:nil];
                [self presentModalViewController:SecondView animated:YES];
                [detailView release]; 
                [self dismissModalViewControllerAnimated:YES];
}

Answer 1

您正在呈现SecondView，这是您的类，而不是您的实例。即使这是对的，你也会马上解雇它。

Answer 2

移动[self dismissModalViewControllerAnimated：YES]; to detailView.m

-(void)newMessageModalView:(NewMessageModalView *)controller didFinishSelecting:(int)selectedChannel{
    SecondView * detailView = [[SecondView alloc] initWithNibName:@"SecondView" bundle:nil];
    [self presentModalViewController:SecondView animated:YES];
    [detailView release]; 
}

例如，在detailView.m

中

- (void)cancelBtnTouched:(id)sender {
    [self dismissModalViewControllerAnimated:YES];
}
