Question

我试图在我的根控制器上单击一个按钮后调用子视图。警告出现在我的AppDelegate中（代码在下面），但是我在根控制器中包含了我如何调用这个新子视图的方法，以防万一也有问题。继续出现的警报是navController的本地声明隐藏了一个实例变量当我启动应用程序（以前打开罚款）时，它现在只是退出...

#import "SEM2REDOAppDelegate.h"
#import "SEM2REDOViewController.h"

@implementation SEM2REDOAppDelegate

@synthesize window;
@synthesize navController;


#pragma mark -
#pragma mark Application lifecycle

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    
    [self.window makeKeyAndVisible];

    SEM2REDOViewController  *firstController = [[SEM2REDOViewController alloc]
                                            initWithNibName:@"SEM2REDOViewController" bundle:nil];
    UINavigationController  *navController = [[UINavigationController alloc]
                                              initWithRootViewController:firstController];

    [self setNavContorller:navController];
    [window addSubview:[navController view]];

    [navController release];
    [firstController release];  

    return YES;
}

然后这是我的第一个视图控制器里面的方法

- (IBAction)chooseFirstMeeting:(id)sender {     
    SelectRotationController *selectView = [[SelectRotationController alloc] 
                                            initWithNibName:@"SelectView" bundle:[NSBundle mainBundle]];
    [selectView.navigationItem setTitle:@"Select First Meeting"];
    [self.navigationController pushViewController:self.selectRotationController animated:YES];
    self.selectRotationController = selectView; 
    [selectView release];
}

我知道这可能是一个非常简单的问题，但我刚刚开始这个。在高中编程深入研究作为一门补充课程，所以我真的很感激任何帮助！
