需求是添加一个容器视图并在containerview中加载所有视图控制器
因此,在load视图中可以像这样创建uiview和container视图

在AppDelegate中,可以这样做

-(BOOL)应用程序:(UIApplication*)应用程序使用选项完成启动:(NSDictionary*)启动选项
{
self.window=[[UIWindow alloc]initWithFrame:[[UIScreen mainScreen]bounds]];
ContainerViewController*容器=[[ContainerViewController alloc]init];
self.window.rootViewController=容器;
//制作一个23页VCs的数组
NSMutableArray*控制器=[NSMutableArray];
[控制器添加对象:firstcontroller];
[控制器添加对象:第二控制器];
[控制器添加对象:…];
[控制器添加对象:twentythreecontroller];
对于(int i=0;i首先移除nstimer并使用性能选择器:withObject:afterDelay:方法,如下所示:
// add delay and method according to your requirement
[self performSelector:@selector(oneView) withObject:nil afterDelay:10];
-(void)oneView
{
//add firstView and perform second selector
[self performSelector:@selector(secondView) withObject:nil afterDelay:10];
}
-(void)secondView
{
//add secondView and perform thirdselector
[self performSelector:@selector(thirdView) withObject:nil afterDelay:10];
}

我正在寻找如何在容器视图中加载。
