我真的不知道如何在不粘贴我的所有代码的情况下解释这一点,但生病了。 “假设”我的.hs和.ms是准确的,我感觉我的.xib设置不正确,但我真的不能粘贴代码。相反,我已压缩文件并上传源代码。 (如果你足够勇敢,它就在这里:http://bit.ly/ZtDkGi)我得到了一个成功的构建,但我的模拟器的屏幕在应用程序启动后只是黑屏。
基本上,我必须手动添加appDelegate对象。我将班级设置为适当的班级 - 但它仍然没有拉动。如果有人能够提供帮助,那就太好了。
这是我的Test_TableViewAppDelegate.h
#import <UIKit/UIKit.h>
@interface Test_TableViewAppDelegate : NSObject <UIApplicationDelegate>
{
}
@property (nonatomic, retain) IBOutlet UIWindow *window;
@property (nonatomic, retain) IBOutlet UINavigationController *navController;
@end
这是我的新 Test_TableViewAppDelegate.m
#import“Test_TableViewAppDelegate.h”
@implementation Test_TableViewAppDelegate
@synthesize window=_window;
@synthesize navController=_navController;
- (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];
UIWindow *window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
window.backgroundColor = [UIColor greenColor];
self.window = window;
UIViewController *fvc = [[UIViewController alloc] init];
UIViewController *rootController = [[UIViewController alloc] initWithNibName:@"RootViewController" bundle:nil];
UINavigationController *nc = [[UINavigationController alloc]initWithRootViewController:rootController];
//UINavigationController *nc = [[UINavigationController alloc]initWithRootViewController:fvc];
self.navController = nc;
//[self.window addSubview: nc.view];
//[self.window makeKeyAndVisible];
self.window.rootViewController = self.navController;
[self.window makeKeyAndVisible];
return YES;
}
RootViewController.h
#import <UIKit/UIKit.h>
@interface RootViewController : UITableViewController {
NSMutableArray *petsArray;
}
@end
RootViewController.m
#import "RootViewController.h"
@interface RootViewController ()
@end
@implementation RootViewController
最后但并非最不重要的是,main.m(我认为这也可能是一个问题)
#import "Test_TableViewAppDelegate.h"
int main(int argc, char *argv[])
{
@autoreleasepool {
return UIApplicationMain(argc, argv, nil, NSStringFromClass([Test_TableViewAppDelegate class]));
}
}
提前谢谢。我很感激:D

Test_TableViewAppDelegate
中的为什么要向窗口添加两次视图?
// you could remove these two lines
[self.window addSubview: nc.view];
[self.window makeKeyAndVisible];
//keep these two lines
self.window.rootViewController = self.navController;
[self.window makeKeyAndVisible];
此视图是您添加到navigationController中的,它不会被任何nib名称
初始化UIViewController *fvc = [[UIViewController alloc] init];
初始化应该在你的委托中
RootViewController *rootController = [[RootViewController alloc] initWithNibName:@"RootViewController" bundle:nil];
UINavigationController *nc = [[UINavigationController alloc]initWithRootViewController:rootController];

我相信您获得黑屏的原因是您没有正确分配和初始化导航控制器!
相反,您应该尝试以下代码:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions: (NSDictionary *)launchOptions
{
// create the base window
UIWindow *window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
window.backgroundColor = [UIColor greenColor];
self.window = window;
[window release];
// this is the home page from the user's perspective
FirstViewController *fvc = [[FirstViewController alloc] init];
UINavigationController *nc = [[UINavigationController alloc]initWithRootViewController:fvc];
self.navigationController = nc;
[fvc release];
[nc release];
// show them
[self.window addSubview: nc.view];
[self.window makeKeyAndVisible];
return YES;
}
希望这有效!
