Question

我为登录创建了简单的Master Detail应用程序。我根据本教程删除了MasterViewController，DetailViewController和Main.storyboard：

在AppDelegate的didFinishLaunchingWithOptions函数中我做了以下更改

    - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.

    self.window=[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen]bounds] ];

    /*UISplitViewController *splitViewController = (UISplitViewController *)self.window.rootViewController;
     UINavigationController *navigationController = [splitViewController.viewControllers lastObject];
     navigationController.topViewController.navigationItem.leftBarButtonItem = splitViewController.displayModeButtonItem;*/

    LoginTableViewController *loginTableViewController=[[LoginTableViewController alloc]initWithNibName:@"LoginTableViewController" bundle:nil ];

    self.navigationController =[[UINavigationController alloc]initWithRootViewController:loginTableViewController];

    self.window.rootViewController=self.navigationController;
    [self.window makeKeyWindow];

    return YES;
}

我在App Delegate函数

中评论了这个函数

  /*
    - (BOOL)splitViewController:(UISplitViewController *)splitViewController collapseSecondaryViewController:(UIViewController *)secondaryViewController ontoPrimaryViewController:(UIViewController *)primaryViewController {
.............................

    }*/

我用子类UITableViewController的xib创建了LoginTableTableViewController。我创建了LoginTableTableViewController.h

 #import "LoginTableViewController.h"

@interface LoginTableViewController ()

@end

@implementation LoginTableViewController
@synthesize arraylogin,userNameTextField,passwordTextField;
bool isKeyboardVisible=FALSE;

- (void)viewDidLoad {
    [super viewDidLoad];
    arraylogin=[[NSArray alloc] initWithObjects:@"user name",@"password",nil];
    //set title
    self.navigationItem.title=@"Best App";

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardAppeared) name:UIKeyboardDidShowNotification object:nil];

    // Uncomment the following line to preserve selection between presentations.
    // self.clearsSelectionOnViewWillAppear = NO;

    // Uncomment the following line to display an Edit button in the navigation bar for this view controller.
    // self.navigationItem.rightBarButtonItem = self.editButtonItem;
}

-(void) loginAction
{
    if([userNameTextField.text isEqualToString:@""] || [passwordTextField.text isEqualToString:@""])
    {

        //   UIAlertView @alert=[[UIAlertView alloc] intitWithTitle:@"alert" messge:@"Please fill in all //the fields" delegate:self cancel]
        UIAlertView *alert=[[UIAlertView alloc] initWithTitle:@"alert" message:@"Please fill in all the fields" delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil];
        [alert show];
        //i will use a code to connect to DB turorial

    }
}
- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}
-(void)keyboardAppeared
{
    if(isKeyboardVisible==false)
    {
        isKeyboardVisible=true;

        UIBarButtonItem *btnGo=[[UIBarButtonItem alloc] initWithTitle:@"Go" style:UIBarButtonItemStyleBordered target:self action:@selector(loginAction)];
        self.navigationItem.rightBarButtonItem=btnGo;
    }

Answer 1

您的项目仍在指定应加载“主”故事板。编辑Info.plist文件以删除故事板条目，它将使您超过当前错误。

（如果在提问时从调试控制台中包含错误消息，那么任何试图提供帮助的人都会更容易。例如：“因未捕获的异常而终止应用程序'NSInvalidArgumentException'，原因：'无法找到一个名为“Main”的故事板“。）

AppDelegate函数未加载表视图控制器
