我有一些UIView，在第一个UIView上有一些按钮，它们的点击功能如下

-(IBAction)securityClicked:(id)sender
{ 

SwitchViewController* switchViewController = (SwitchViewController*)[wangfan_chevyAppDelegate App].viewController;
[switchViewController.wtccviewcontroller.scrollView1 setContentOffset:CGPointMake(
                            1024*0, 0) animated:false];
[[testAppDelegate App] pushViewFromRight:switchViewController.wtccviewcontroller
                                            over:self];

}

wtccviewcontroller.m文件的代码是

因为有很多控制器，所以当我单击第一个视图上的按钮时，它会被加载很长时间，甚至退出应用程序，所以我应该如何使它运行良好？

首先，如果你调用[alloc]，你创建了一个对象（针对每个控制器），那么你必须释放它。可以在添加子视图后执行此操作，因为这样会保留它

我看到你评论了几次[controller release]，然后完全忘记了它

此外，您还在这里添加了许多控制器。您可以在viewDidLoad中添加第一个，并且只有在单击时才可以惰性地加载其他控制器。

您的代码至少存在三个主要问题：

你在疯狂地泄漏物品。您正在分配多个视图控制器，但从未释放它们。事实上，由于正在重新分配

控制器

变量，因此将丢失对这些对象的引用，因此无法释放它们

不要使用多个

UIViewController

对象来控制单个视图的部分。视图控制器设计用于全屏（或作为

UINavigationController

、

UITabBarController

等的一部分）。您应该使用单个

UIView

对象，并从中央控制器对象控制它们和/或使用您自己的轻量级视图控制器

最终视图大小约为8192x768；这是巨大的。至少，您可以使用

UITableViewController

智能地缓存部分视图。不过，这个屏幕可能应该拆分成更小的视图
