[__NSCFNumber length]: unrecognized selector sent to instance UITableView

i'm experiencing an error

[__NSCFNumber length]: unrecognized selector sent to instance 0x15580c90
2014-02-18 15:10:49.490 CIB[1706:60b] * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFNumber length]: unrecognized selector sent to instance 0x15580c90'

libc++abi.dylib: terminating with uncaught exception of type NSException

I have loop here. from array in Json to my model tasklist then stored to NSMutableArray _tasklist

NSArray *taskJson = [json objectForKey:@"fOTaskListModelWss"];

for (NSDictionary *dictCQ in taskJson) {
NSLog(@"TASKLIST: %@", [dictCQ objectForKey:@"foTaskListModelWs"]);

NSDictionary *datadic = [dictCQ objectForKey:@"foTaskListModelWs"];
TaskList *task = [[TaskList alloc]init];
[task setTaskCount:datadic[@"count"]];
[task setFuncCd:datadic[@"funcCd"]];
[task setFuncCdDscp:datadic[@"funcCdDscp"]];
[task setRequestStatus:datadic[@"requestStatus"]];
[task setRole:datadic[@"role"]];
[_taskList addObject:task];

then here is my code in cellForRowAtRowPathIndex

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString * simpleTableIdentifier = @"MenuTableViewCell";
MenuTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil) {
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"MenuTableViewCell" owner:self options:nil];
cell = [nib objectAtIndex:0];
TaskList *txn = [_taskList objectAtIndex:indexPath.row];
cell.titleLabel.text = txn.funcCdDscp;
cell.totalCountLabel.text = txn.taskCount;
return cell;}

Answer Source
cell.titleLabel.text = txn.funcCdDscp;
cell.totalCountLabel.text = txn.taskCount;

One of these (not sure which, but my guess would be taskCount) is a NSNumber. Text takes an NSString.
