缺乏对碰撞报告的理解
我有这个崩溃报告。

我也用iPad试过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]; self.introtext = new.News_IntroText; self.content.font = [UIFont systemFontOfSize:currentsize]; self.date.text = new.News_ArticalDate; self.commentno.text = @"留言: 0"; imagepath = new.News_ImagePath; onetime = YES; if([Constant_Config NetworkStatus]){ if(![imagepath isEqualToString:@"no picture"]){ NSOperationQueue *queue = [NSOperationQueue new]; NSInvocationOperation *operation = [[NSInvocationOperation alloc] initWithTarget:self selector:@selector(loadImage) object:nil]; [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]; }
你正在看的是一个堆栈跟踪，程序通过你的代码的path。 每行是一个函数，从主运行循环（18）开始，到崩溃（0）结束。
最有用的部分是您在第3帧的应用程序OrientalDailyiOS中创build的function。
您的应用程序崩溃尝试访问Main_NewsDetail viewDidLoad]方法（第3帧）内的NSArray（第2帧）中的对象。
编辑
正如我所说，你的应用程序崩溃尝试访问一个NSArray中的对象。 仔细看看你的应用程序，特别是你的viewDidLoad方法中的两行，这个方法使用了在objectAtIndex:之上崩溃的方法。
font = [self.defaultsize objectAtIndex:0]; News *new = [self.singlenews objectAtIndex:0];
你如何填充self.singlenews ？ 如果没有物体，情况如何呢？
