iphone - 解雇ModalViewController 的问题

Question

当我关闭模态视图时遇到问题:

我有一个带有五个选项卡的 tabBar。 我在第四个选项卡上，显示模态视图。 当我驳回它时。我进入第一个选项卡，但我想留在第四个选项卡上。

为了显示模态，我在父 Controller 中调用此方法:

[self presentModalViewController:controller animated:YES];

为了隐藏模式，我在父 Controller 中调用此方法:

[self dismissModalViewControllerAnimated:YES];

我已经尝试调用 self.tabBarController/self.navigationController 方法而不是 self 方法，但这是同样的问题。

有人有想法吗？

编辑:

我调用第四个选项卡 Controller 中的方法。

这是上下文:

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
    UIImagePickerController *imgPicker = [[UIImagePickerController alloc] init];
    imgPicker.allowsEditing = NO;
    imgPicker.delegate = self;
    switch (buttonIndex) {
        case 0: {
            [[NSUserDefaults standardUserDefaults] setBool:YES forKey:kMobiglissFromPicker];
            imgPicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
            [self presentModalViewController:imgPicker animated:YES];
            break;
        }
        case 1: {
            if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
                [[NSUserDefaults standardUserDefaults] setBool:YES forKey:kMobiglissFromPicker];
                imgPicker.sourceType = UIImagePickerControllerSourceTypeCamera;
                [self presentModalViewController:imgPicker animated:YES];
            }               
            break;
        }
    }
}

- (void)imagePickerController:(UIImagePickerController *)imgPicker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    UIImage *origin = [info objectForKey:@"UIImagePickerControllerOriginalImage"];

    UIImage *photo = [origin thumbnailImage:280
                          transparentBorder:0.0
                               cornerRadius:0.0
                       interpolationQuality:kCGInterpolationHigh];

    [icon replaceImageWithImage:photo];

    [serverProxy updateProfileAvatar:photo];
    [self dismissModalViewControllerAnimated:YES];
    imgPicker.delegate = nil;
}

- (IBAction)editAvatar:(id)sender {
    NSString *camera = [UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera] ? [WPLanguage get:@"SignupPhotosheetCamera"] : nil;
    UIActionSheet *photoSheet = [[UIActionSheet alloc] initWithTitle:[WPLanguage get:@"SignupPhotosheetTitle"]
                                                            delegate:self 
                                                   cancelButtonTitle:[WPLanguage get:@"CANCEL"] 
                                              destructiveButtonTitle:nil 
                                                   otherButtonTitles:[WPLanguage get:@"SignupPhotosheetGallery"], camera, nil];
    [photoSheet showInView:self.view];
}

只是猜测(您需要添加更多详细信息):您的 viewController(实现了 UITabBarDelegate)是否在 viewWillAppear:(或其中之一)上设置了所选项目还调用其他方法吗？
