refresh textfield without exiting view

hi

I have four textfield in a view. now when user clicks the clear button, all four textfield will be clear. after button is press, i set the all the textfield = @" ", how can i refresh the view so that this change is shown, with out exiting the view.

tHks

 

hi, the clear button is not the textfield itself clear button, which only clear its particular row. i implemented a "clear all textfield button"

Code:

-(IBAction)ClearAll
{ 
	UIAlertView *alert = [[UIAlertView alloc] initWithTitle:
						  @"Delete All?"
													message:nil
												   delegate:self 
										  cancelButtonTitle:@"Cancel" 
										  otherButtonTitles:@"OK", nil
						  ];
	[alert show];
	[alert release];	
		
}

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
	// the user clicked one of the OK/Cancel buttons
	if (buttonIndex == 0)
	{
		field1.text = @" ";
		field2.text = @" ";
		field3.text = @" ";
		field4.text = @" ";
		

}		
}

thks
