我想用XCode 4.2为iPhone编写应用程序。我使用tabbar来切换这个应用程序的功能。 我需要“情境”:在tabbar中记录一个“情况”,第二个“情况”是登录标签栏。因此我想到了两个想法:要么我使用两个故事板并动态使用故事板,要么只使用一个故事板并使用两个场景(登录并登录)并动态分配viewcontroller。但我不知道我怎么能编程这个.. 你是什么意思我必须做什么?我怎么能这样做?
感谢您的回答:)

中的代码
using System.Windows.Media.Animation;
public partial class animation : Window
{
string Name;
public animation()
{
this.InitializeComponent();
// Insert code required on object creation below this point.
}
private void btn_animation_1_Click(object sender, RoutedEventArgs e)
{
Button button = (Button)sender;
Name = button.Name;
Animation_In_All();
}
public void Animation_In_All()
{
Storyboard SB = (Storyboard)(FindResource("one_in_all"));
Storyboard.SetTargetName(SB.Children[0], Name);
SB.Begin();
}
private void btn_animation_2_Click(object sender, RoutedEventArgs e)
{
Button button = (Button)sender;
Name = button.Name;
Animation_In_All();
}
}
