我的应用程序从根控制器开始，称为我创建
TaskController : UINavigationController的类的根视图控制器（它已添加为视图 UITableView）；当我启动应用程序时，我只看到TaskRootController 的标题和它的背景颜色。但我没有看到表格视图。如果我的应用程序以 TaskRootController 作为 rootViewController 开始，我会看到表格视图。UINavigationControllerTaskRootController : UIViewController<UITableViewDelegate>
在可能的情况下如何查看表格视图？PS。即使我将 TaskRootController 切换到 TaskRootController : UITableViewController 行为也是一样的。我的代码如下：
AppDelegate.m
@implementation AppDelegate
@synthesize window = _window;
@synthesize taskController;
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
self.window.backgroundColor = [UIColor whiteColor];
self.taskController = [TaskController alloc];
self.window.rootViewController = self.taskController;
[self.window makeKeyAndVisible];
return YES;
}
- (void)applicationWillResignActive:(UIApplication *)application
{
}
- (void)applicationDidEnterBackground:(UIApplication *)application
{
}
- (void)applicationWillEnterForeground:(UIApplication *)application
{
}
- (void)applicationDidBecomeActive:(UIApplication *)application
{
}
- (void)applicationWillTerminate:(UIApplication *)application
{
}
@end
任务控制器.m
@implementation TaskController
@synthesize taskRootController;
- (void) pushInboxController
{
TaskBoxController *taskBoxController = [[TaskBoxController alloc] initWithNibName:nil bundle:NULL];
[self pushViewController:taskBoxController animated:YES];
}
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
[self.navigationBar setBarStyle: UIBarStyleBlack];
[self.navigationBar setTranslucent: NO];
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
self.taskRootController = [[TaskRootController alloc] initWithNibName:nil bundle:NULL];
UIViewController *root = self.taskRootController;
[self initWithRootViewController: root];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear: animated];
[self performSelector:@selector(pushInboxController)];
}
@end
任务根控制器.m
@implementation TaskRootController
@synthesize taskRootView;

// Custom initialization
}
return self;
}
- (void)viewDidLoad
{

NSLog(@"SIZE x:%f,y:%f ; %f:%f", self.view.bounds.origin.x, self.view.bounds.origin.y, self.view.bounds.size.width, self.view.bounds.size.height);
self.view.backgroundColor = [UIColor grayColor];

self.taskRootView = [[UITableView alloc] initWithFrame: CGRectMake(0, 0, self.view.bounds.size.width, self.view.bounds.size.height) style:UITableViewStyleGrouped];

self.taskRootView.dataSource = self;
[self.view addSubview:self.taskRootView];
}

}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
// Return the number of sections.
return 1; // put number for section.
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
// Return the number of rows in the section.
return 6; // put number as you want row in section.
}
- (CGFloat) tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
CGFloat result = 20.0f;
if([tableView isEqual:self.taskRootView])
{
