How can we display number values in UILabels in iOS? - ios

Question

I am very new for iOS and in my app I am integrating services and after getting response from service I am storing the values in Array-list.
When I load that array list values in tableList showing exception like:
_Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFNumber length]: unrecognized selector sent to instance 0x7d7ca000'
McoIdArray:-(
106314100491,
106314100492,
106314100493,
106314100494,
106314100495
)
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *simpleTableIdentifier = #"MyCell";
Cell = (CoridersCell *)[tableList dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (Cell == nil)
{
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"CoridersCell" owner:self options:nil];
Cell = [nib objectAtIndex:0];
}
Cell.mcoId.text = [McoIdArray objectAtIndex:indexPath.row];
return Cell;
}

Answer 1

The problem is you are assigning an NSNumber instance instead of an NSString. You should format the number to a string like this:
NSNumber* number = [McoIdArray objectAtIndex:indexPath.row];
cell.mcoId.text = [NSString localizedStringWithFormat:#"%#", number];
If you want to have more control over number formatting you can use NSNumberFormatter.

Answer 2

Your array contains instances of NSNumber, not NSString. So you can't directly assign the value from the array to the label's text property. You must first convert the NSNumber to an NSString.
One option is to use the stringValue method.
Cell.mcoId.text = [McoIdArray[indexPath.row] stringValue];
Also note the use of modern syntax to access the array.
Replace the line:
Cell.mcoId.text = [McoIdArray objectAtIndex:indexPath.row];
with the line I show above.
