在tableview里添加UItextfield
CGRect frame = CGRectMake(cell.frame.origin.x, cell.frame.origin.y, self.view.bounds.size.width, 44);
textFieldFunction = [[UITextField alloc] initWithFrame:frame];
textFieldFunction.borderStyle = UITextBorderStyleBezel;
textFieldFunction.textColor = [UIColor blackColor];
textFieldFunction.font = [UIFont systemFontOfSize:15.0];
textFieldFunction.placeholder = @"請選擇職能";
textFieldFunction.backgroundColor = [UIColor whiteColor];
textFieldFunction.tag = 4; // tag this control so we can remove it later for recycled cells
textFieldFunction.enabled = NO;
[cell addSubview:textFieldFunction];
