IOS8 APP崩溃，应用程序在iOS7上运行正常

Question

Crash starts when we kill the application and Again login to the application, App keep crashing at multiple views and screens.

Zombie warning sometimes says message was sent to deallocated space ie. [ 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' , sometimes else and it's random.`

App worked fine on iOS7, issue only with iOS8

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];

Tried once more this time, i got this error below error message this time.
