在MainWindow.xib中加载视图.xib

Question

这可能是一个非常愚蠢的错误，但我花了超过4天的时间寻找解决方案。

这很简单，我有我的MainView.xib和一个名为FirstViewController（h/m/xib）的视图。

在MainWindow.xib中，我添加一个UIViewController并将类名更改为FirstViewController并设置了Nib名称（altouhg，我试过两种方法）。

我想它必须做一些事情，但我不能告诉，因为我是一个iOS开发新手，任何帮助都会非常有帮助。

进出口使用的XCode 3.2和Interface Builder，与SDK 4.3

的AppDelegate

#import <UIKit/UIKit.h>

    NSInteger intramurosBadgeNumber;

这听起来像你FirstViewController不被保留 - 如果它是没有分配到任何地方的插座，没有东西保留它，它会消失。某处添加一个属性（AppDelegate中，也许，如果这就是你所得到），并连接到控制器：

@property (nonatomic, retain) IBOutlet UIViewController *firstViewController;
