IOS8 APP崩溃，应用程序在iOS7上运行正常

Question

当我们终止该应用程序并再次登录该应用程序时，崩溃开始，App继续在多个视图和屏幕上崩溃。

僵尸警告有时会说消息已发送到已释放空间。 [ object of View setImage:forState]. Sometmes *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[__NSArrayM insertObject:atIndex:]: object cannot be nil' [ object of View setImage:forState]. Sometmes *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[__NSArrayM insertObject:atIndex:]: object cannot be nil' ，有时其他情况是随机的。

应用在iOS7上运行良好，仅在iOS8上有效

象征性崩溃日志之一：

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，这次我在错误消息下方收到此错误。

当我尝试打印十六进制时，我得到了：

我遇到了同样的问题，只需将单元格的唯一标识符更改为Cell 。
