Question

在以下代码中出现内存泄漏...请帮我解决这个问题..

if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
    //iPad specific code.
    universalApp=1;
    NSLog(@"ipad started.......");
    // Override point for customization after application launch
    window.frame = CGRectMake(0, 0, 768, 1004);
    //window.frame = CGRectMake(0, 0,320,460);

    mainPageController = [[MainPageController alloc] initWithNibName:@"MainPageController" bundle:nil];
    //  [mainPageController.view setFrame:CGRectMake(0, 20, 320, 460)];

    [window addSubview:mainPageController.view];//memory leak

    [window makeKeyAndVisible];

Answer 1

假设您在mainPageController或您的应用代表的-applicationWillTerminate:中发布-dealloc，我认为没有泄漏。有什么问题？

Answer 2

如果您不在 -applicationWillTerminate：或您的应用委托的 -dealloc 中发布主页控件，则应该发布 NoPage Witherspoon < / strong>说。

因此，如果您不使用ARC，则应修改此类代码：

mainPageController = [[[MainPageController alloc] initWithNibName:@"MainPageController" bundle:nil] autorelease];

或

[window addSubview:mainPageController.view];//memory leak [mainPageController release]; [window makeKeyAndVisible];

当然，您应该阅读Advanced Memory Management Programming Guide
