Objective c 如何在imagePickerController:didFinishPickingMediaWithInfo之后更改视图（XIB）？

我是iphone和objective-c开发的新手

我想知道相机拍照后如何更改视图（XIB文件）

有人能帮我或分享一些代码吗？我从一周前开始搜索：( 完成应用程序后，我准备分享我的项目和/或制作教程

关于我的应用程序的信息：我想扫描条形码并将条形码保存在我的应用程序中。 用于使用ZBARDK扫描条形码iam。 我有一个Tabbar控制器，在第一个选项卡上，我可以打开相机。 扫描过程结束后，我想跳转到第二个选项卡（另一个XIB文件）并显示结果

谢谢你的帮助

这里是第一个选项卡（ScanCodeViewController）的代码：

h

---

在

did完成PickingMediaWithInfo

中，您应该调用

[self.tabbar controller setSelectedIndex:1]

切换到第二个选项卡。

明白了

无法设置更多动画：是。 下面是示例和正确的代码

我希望它能帮助别人

- (void) imagePickerController: (UIImagePickerController*) reader
 didFinishPickingMediaWithInfo: (NSDictionary*) info
{

    // ADD: get the decode results
    id<NSFastEnumeration> results =
    [info objectForKey: ZBarReaderControllerResults];
    ZBarSymbol *symbol = nil;
    for(symbol in results)
        break;

[reader dismissModalViewControllerAnimated: NO];

    TableDetailViewController *tc = [[TableDetailViewController alloc]         initWithNibName:@"TableDetailViewController" bundle:nil];
    tc.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
    [self presentModalViewController:tc animated:YES];
    [tc release];   

}

-（无效）imagePickerController:（UIImagePickerController*）读卡器
didFinishPickingMediaWithInfo:（NSDictionary*）信息
{
//添加：获取解码结果
id结果=
[信息对象forkey:ZBarReaderControllerResults]；
ZBarSymbol*符号=nil；
用于（结果中的符号）
打破
[reader dismissModalViewControllerAnimated:否]；
TableDetailViewController*tc=[[TableDetailViewController alloc]initWithNibName:@“TableDetailViewController”捆绑包：nil]；
tc.ModAltTransitionStyle=UIModAltTransitionStyleFlipHorizontal；
[自我呈现ModalViewController:tc动画：是]；
[tc释放]；
}

非常感谢您的回答。您能告诉我如何在imagePickerController:didFinishPickingMediaWithInfo:之后显示XIB文件吗？我的目标是加载另一个XIB文件，并在加载的XIB文件中显示捕获的图片和编码代码
