XCode将SingleView改变成空白模板

1、将Main.storyboard删除

2、将"项目名-Info.plist"文件的main storyboard file base name删除(选中,按delete键)

3、在AppDelegate的

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions方法中写入以下代码(在arc上这样写,mrc上加上aoturelase)

self.window = [[UIWindowalloc]initWithFrame:[UIScreenmainScreen].bounds];

    _window.backgroundColor = [UIColorwhiteColor];

   [_window makeKeyAndVisible];
