IOS8 APP崩溃，应用程序在iOS7上运行良好

Question

当我们终止应用程序并且再次登录到应用程序时崩溃开始，应用程序会在多个视图和屏幕上崩溃。

僵尸警告有时会说消息被发送到解除分配的空间，即。 [ object of View setImage:forState]. Sometmes *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[__NSArrayM insertObject:atIndex:]: object cannot be nil'，有时候，它是随机的。

App在iOS7上运行良好，仅适用于iOS8

其中一个符号化崩溃日志：

NSInteger index1, index2, index3;

index1= indexPath.row * MAX_NUMBER_OF_CELLS_IN_ONE_ROW;
index2=  index1 + 1;
index3=  index2 + 1;

static NSString *TableIdentifier = @"CellIdent";

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:TableIdentifier];

UIView *Mainview = nil;

if (cell == nil) {
    cell = [[[UITableViewCell alloc] init]autorelease];
    NSArray *nib=[[NSBundle mainBundle]loadNibNamed:@"CaseManagementCell" owner:self options:nil];
    Mainview = (UIView *)[nib objectAtIndex:0]; 
    [cell addSubview:Mainview];
}

cell.backgroundColor = [UIColor clearColor];

这次再次尝试，我这次收到此错误错误消息。

  

NSPathStore2 setImage：forState：]：无法识别的选择器发送到实例0x786bc950

当我尝试打印十六进制时，我得到了：

我遇到了同样的问题，只是通过将单元格的唯一标识符更改为Cell来解决问题。
