我正在编写一个 iOS 应用程序;没有 ARC,也没有故事板。我在导航控制器中有一个视图控制器。它应该有推到第二个视图的表格视图和导航按钮。这是我得到的错误:
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-[UIViewController _loadViewFromNibNamed:bundle:] loaded the "ViewController" nib but the view outlet was not set.'
*** First throw call stack:

libc++abi.dylib: terminate called throwing an exception
(lldb)
AppDelegate 中的代码:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
self.viewCon = [[ViewController alloc]initWithNibName:@"ViewController" bundle:nil];
self.navCon = [[UINavigationController alloc]initWithRootViewController:self.viewCon];
self.navCon.navigationBar.tintColor= [UIColor greenColor];
self.viewCon.title= @"First View";
self.tblView = [[UITableView alloc] init];
NSMutableArray *viewArr=[[NSMutableArray alloc] init];
[viewArr addObject:self.navCon];
self.navBar = [[UINavigationBar alloc] init];
self.viewCon.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Second View" style:UIBarButtonSystemItemAdd target:self action:(nil)];
[self.window addSubview:self.navBar];
self.window.rootViewController = self.viewCon;
[self.window makeKeyAndVisible];
return YES;
}
在这个阶段,我什至无法运行应用程序。可能是什么问题?最好的祝福
