Answer 1

if the textField is in your custom cell, you can handle the textField... events in the customCell.m too.

if you do so, you can call the methode simply with [self printStuff]; in

- (BOOL)textFieldShouldReturn:(UITextField *)textField

//CustomCell.h
// ...
@interface CustomCell : UITableViewCell 
{
    //...
}

-(void)printStuff;

@end

//CustomCell.m

//...

-(void)printStuff
{
    //...
}

-(BOOL)textFieldShouldReturn:(UITextField *)textField
{
    //...
    [textField resignFirstResponder];

    [self printStuff];

    return YES;
}

or if the printStuff methode is in you tableView class, you can declare a protocol

// CustomCell.h
@protocol CustomCellProtocol 

-(void)printStuff:(NSString *)stuff;

@end

@interface CustomCell UITableViewCell 

@property (nonatomic, assign)UIViewController *parent;

// CustomCell.m
-(void)printStuff:(NSString *)stuff
{
    [parent printStuff:stuff];
}


// TableViewClass.h
...
@interface TableViewClass : UITableViewController


// TableViewClass.m
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    customCell *cell=[tableView dequeueReusableCellWithIdentifier:@"charCell"];
    if (cell == nil || (![cell isKindOfClass: customCell.class]))
    {
        cell=[[customCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"charCell"];
        cell.parent = self; // or with a custom setter methode
    }
    return cell;
}
