[iOS入门系列]Xcode创建空模板应用

1、设置AppDelegate类

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    self.window.backgroundColor = [UIColor whiteColor];
    [self.window makeKeyAndVisible];

    <#UIViewController#> *vc = [[<#UIViewController#> alloc] init];
    self.window.rootViewController = vc;

    return YES;
}

2、取消Storyboard的引用

• 选中工程名
• 选中TARGETS
• 选中General
• 在Deployment info 下找到Main Interface 去掉默认的 Main即可
