Question

I have several UITextField in UITableView. I have assigned different tags to those fields but the problem that i am facing is accessing those UITextField from several other functions.

How to access them?
Here is my code:-

UITextField *textField = (UITextField *)[self.view viewWithTag:0];

Can anyone help?

I have same feature in one of my apps and I used below code to accomplish that and I never had this kind of problem.

First of all you need to store all your textField value temporary in Array. Make array like this.

arrTemp=[[NSMutableArray alloc]initWithObjects:[NSString stringWithFormat:@""],
 [NSString stringWithFormat:@""],
 [NSString stringWithFormat:@""],
 [NSString stringWithFormat:@""],
 [NSString stringWithFormat:@""],
 [NSString stringWithFormat:@""],
 [NSString stringWithFormat:@""],
 [NSString stringWithFormat:@""],
 [NSString stringWithFormat:@""],nil];

Then Give all textField tag = indexPath.row;

After that You need to replace textField value in below two methods.

-(BOOL)textFieldShouldReturn:(UITextField *)textField{
   [arrTemp replaceObjectAtIndex:textField.tag withObject:textField.text];
}

-(void)textFieldDidEndEditing:(UITextField *)textField{
 [arrTemp replaceObjectAtIndex:textField.tag withObject:textField.text];
}

At Last You need to set that value in cellForRowAtIndexPath datasource Method. So that whenever user scroll tableview it set previous value from temp array. Like this.

cell.txtEntry.text = [arrTemp objectAtIndex:indexPath.row];
