ios - 错误 : UITableViewController loaded the "TableViewController" nib but didn't get a UITableView HOWEVER I've already deleted the NIB file

Question

在我的应用程序中，我正在将 UITableView 从以编程方式添加更改为通过 XIB 添加。决定放弃这个想法并返回，但现在应用程序崩溃了

message:Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-[UITableViewController loadView] loaded the "TableViewController" nib but didn't get a UITableView.'

我在其他地方阅读所以我应该返回并从 NIB 中删除连接，但我已经删除了 NIB 文件!那么有什么建议吗？

//ViewController.h
#import <UIKit/UIKit.h>

@interface TableViewController : UITableViewController <UITableViewDelegate,
UITableViewDataSource, UIAlertViewDelegate>

@property (nonatomic) CGFloat rowHeight;
@property (nonatomic, retain) NSManagedObjectContext *context;
@property (nonatomic, retain) NSMutableArray *arr;

@end

//ViewController.m
#import "TableViewController.h"
#import "AddNewExViewController.h"
#import "Exercises.h"
#import "DetailViewController.h"

@interface TableViewController ()

@end

@implementation TableViewController

@synthesize context, arr;

- (id)initWithStyle:(UITableViewStyle)style
    {
    self = [super initWithStyle:style];
    if (self) {
        self.title = @"Exercises";

    }
    return self;
}

- (void)viewWillAppear:(BOOL)animated
{
    NSEntityDescription *entity = [NSEntityDescription entityForName:@"Exercises"
inManagedObjectContext:context];
    NSFetchRequest *request = [[NSFetchRequest alloc] init];
    [request setFetchBatchSize:20];
    [request setEntity:entity];
    NSSortDescriptor *sort = [[NSSortDescriptor alloc] initWithKey:@"name" ascending:YES];
    NSArray *newArray = [NSArray arrayWithObject:sort];
    [request setSortDescriptors:newArray];
    NSError *error;
    NSMutableArray *results = [[context executeFetchRequest:request error:&error] mutableCopy];
    [self setArr:results];
    [self.tableView reloadData];
}

 - (void)viewDidLoad
{
    [super viewDidLoad];

    self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc]    initWithBarButtonSystemItem:UIBarButtonSystemItemTrash target:self action:@selector(deleteAll)];

    self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(add)];

    self.tableView.rowHeight = 60.f;
}

编辑:

//AppDelegate.m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{    
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

    TableViewController *table = [[TableViewController alloc] init];

    table.context = self.managedObjectContext;

    UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:table];

    /*nav.toolbarHidden = NO;*/ //uncomment if you want a tool bar at bottom of tableView

    self.window.rootViewController = nav;
    self.window.backgroundColor = [UIColor whiteColor];
    [self.window makeKeyAndVisible];
    return YES;
}

你如何初始化这个 Controller ？它是程序中唯一的 Controller 吗？如果是这样，请在 Appdelegate didfinishloadingwithoptions 上发布一些代码

清理你的项目(xcode > project menu > clean)并重置你的模拟器，看看问题是否仍然存在。还要通过在此处放置断点来确保您的代码到达 TableViewController 中的 initWithStyle 方法。
