然而，我不知道错误在哪里，我玩我的应用程序，但没有显示错误。

我也尝试过使用iPad的iOS 6，没问题。

苹果的反馈是什么

We found that your app crashed on iPad running iOS 6, which is not in compliance with the App Store Review Guidelines.

Your app crashed on both Wi-Fi and cellular networks when we:

1. Launch the app.
2. Tap any item on main page.
3. App crashes.

更新

Main_NewDetails

- (void)viewDidLoad
{
[super viewDidLoad];
[slider setHidden:YES];
DatabaseAction *getnews = [[[DatabaseAction alloc] init] autorelease];
self.singlenews = [getnews retrieveSingleNews:newsid];
self.defaultsize = [getnews retrieveFont];
font = [self.defaultsize objectAtIndex:0];
currentsize = font.Font_Size;
News *new = [self.singlenews objectAtIndex:0];
if(self.catsid != 10)
    self.header.text = new.News_Cat_Name;
else
    self.header.text = @"評論";
self.title.text = new.News_Title;
authortext = new.News_Author;
self.content.text = [NSString stringWithFormat: @"%@%@", new.News_IntroText,  new.News_FullText];

        [queue addOperation:operation];
        [operation release];
    }

    NetworkHandler *networkHandler=[[NetworkHandler alloc] init];
    GetTotalCommentsRequest *gettotalcomments= [[GetTotalCommentsRequest alloc] init:newsid];

    [networkHandler setDelegate:self];
    [networkHandler request:gettotalcomments];
    [gettotalcomments release];
    [networkHandler release];

    [self.scrollView addSubview:[self addbanner]];
    [self.scrollView addSubview:[self addbanner]];
}

[self setlabelXY];

AppDelegate *appDelegate = [[UIApplication sharedApplication] delegate];
[appDelegate openSessionWithAllowLoginUI:NO];
}

Answer 1

您正在查看的是堆栈跟踪，即程序遍历代码的路径。每一行都是一个函数，从主运行循环（18）开始，到崩溃结束（0）。

最有用的部分是您在第3帧的应用OrientalDailyiOS中创建的功能。

您的应用在试图访问Main_NewsDetail viewDidLoad]方法（第3帧）内的NSArray（第2帧）中的对象时崩溃。

修改

正如我所说，你的应用程序在尝试访问NSArray中的对象时崩溃了。仔细查看您的应用程序，特别是viewDidLoad方法中使用上面objectAtIndex:崩溃的方法的两行。

font = [self.defaultsize objectAtIndex:0]; News *new = [self.singlenews objectAtIndex:0];

您如何填充self.singlenews？它可能没有任何对象是什么情况？

缺乏理解崩溃报告
