xcode4.2推荐使用storyboard,但网上资料太少,书上讲的也都是基于xib的
花了2天时间,终于把xib的helloWorld写出来了。
注意,类名一定要大写,为了这个东西,我搞了2天,在配viewContorller时一直抛错。
新建 Empty Application
添加一个object,添加一个View Controller,添加一个window,
把File's Owner的 custom class 改成 UIApplication
把Object的custom class 改成 自己的 delegate,我的是HelloAppDelegate
然后新建 Cocoa Touch 下的UIViewControllersubclass
拖一个label进去,写上hello world
然后,回到MainWindow中,把ViewController的custom class 改成HelloViewController
然后拖线:
File's Owner拖到 delegate,从delegate拖到viewcontroller和window
然后修改代理类里的
- - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
- {
- //self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
- // Override point for customization after application launch.
- //self.window.backgroundColor = [UIColor whiteColor];
- [self.window addSubview: self.viewController.view];
- [self.window makeKeyAndVisible];
- return YES;
- }
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { //self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease]; // Override point for customization after application launch. //self.window.backgroundColor = [UIColor whiteColor]; [self.window addSubview: self.viewController.view]; [self.window makeKeyAndVisible]; return YES; }
运行即可~
