未声明的导航对象？
我已经像这样声明了导航对象
UINavigationController *naviButtonpro;
@property (nonatomic, retain) IBOutlet UINavigationController *naviButtonpro;
，并且还声明了@synthesize naviButtonpro；
self.naviButtonpro = [[UINavigationController alloc] initWithNibName:@"NaviButtonViewController" bundle:nil];
[self.window addSubview:self.naviButtonpro.view];
当我使用这种方法时，
-(IBAction)displayNextPage:(id)sender
{
dispNext *gotoback = [[dispNext alloc] initWithNibName:@"dispNextView" bundle:[NSBundle mainBundle]];
//UINavigationController *naviButtonpro = [[UINavigationController alloc] initWithNibName:@"NaviButtonViewController" bundle:nil];
[self.naviButtonpro pushViewController:gotoback animated:YES];
[gotoback release];
}
我收到这样的错误 请求成员“naviButtonpro”不是结构或联合，
你能告诉我如何解决这个问题吗
already i am declared navigation object like this
UINavigationController *naviButtonpro;
@property (nonatomic, retain) IBOutlet UINavigationController *naviButtonpro;
and also declared @synthesize naviButtonpro;
self.naviButtonpro = [[UINavigationController alloc] initWithNibName:@"NaviButtonViewController" bundle:nil];
[self.window addSubview:self.naviButtonpro.view];
when i am using this method
-(IBAction)displayNextPage:(id)sender
{
dispNext *gotoback = [[dispNext alloc] initWithNibName:@"dispNextView" bundle:[NSBundle mainBundle]];
//UINavigationController *naviButtonpro = [[UINavigationController alloc] initWithNibName:@"NaviButtonViewController" bundle:nil];
[self.naviButtonpro pushViewController:gotoback animated:YES];
[gotoback release];
}
i am geting an error like this
Request for member 'naviButtonpro' in something not a structure or union
can u tell me the how to resolve this problem

这里有 2 件事需要注意。
首先，您没有创建 UINavigationController。您需要分配 init 它。您似乎在代码中包含它，但它被注释掉了。
其次，dispNext需要子类化&继承自 UIViewController。它有这个功能吗？
2 things to note here.
Firstly, you aren't creating a UINavigationController. You need to alloc init it. You seem to have it in the code but its commented out.
Secondly, dispNext needs to subclass & inherit from UIViewController. Does it do this?
第一个问题是您初始化“naviButtonpro”的位置，第二个问题是
你的接口类继承了什么样的类？是 UIView 还是 UIViewController。
The first problem is where you are initializing the 'naviButtonpro' and second is
What kind of the class its inherited of your interface class ? is it UIView or UIViewController.
