    copied!<p>I have to render dynamic form in iPhone application using tableview. This form may have multiple UI controls as button,textfield,lable, picker,date picker .</p> <p>I got one sample code for iPad which is able to render the dynamic form,but <a href="https://github.com/ecrichlow/iPad-Dynamic-Table-Cells" rel="nofollow">this</a> sample code is using UIPopoverController, which is not supported by iPhone application. So I am looking for some sample code which should work in iPhone.</p> <p>Below is the code which shows combo box on clicking the button in dynamic form. I need the code which should show picker with list items.</p> <p>sample code: <a href="https://github.com/ecrichlow/iPad-Dynamic-Table-Cells" rel="nofollow">https://github.com/ecrichlow/iPad-Dynamic-Table-Cells</a></p> <pre><code>- (IBAction)buttonPressed:(id)sender { [delegate rowItemWasSelected:self]; if (self.itemControlType == ControlTypeToggleButton) { ... } else if (self.itemControlType == ControlTypePopup) { ... } else if (self.itemControlType == ControlTypeCombo) { UITableViewController *popoverTable = [[[UITableViewController alloc] initWithStyle:UITableViewStylePlain] autorelease]; UIToolbar *toolbar = [[[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, DEFAULT_POPOVER_WIDTH, DEFAULT_TOOLBAR_HEIGHT)] autorelease]; UIView *containerView = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, DEFAULT_POPOVER_WIDTH, ([self.controlSelections count] * popoverTable.tableView.rowHeight) + DEFAULT_TOOLBAR_HEIGHT)] autorelease]; UIViewController *containerViewController = [[[UIViewController alloc] init] autorelease]; UIPopoverController *popoverController = [[UIPopoverController alloc] initWithContentViewController:containerViewController]; UITextField *textField = [[UITextField alloc] initWithFrame:CGRectMake(DEFAULT_COMBO_TEXTFIELD_MARGIN, (DEFAULT_TOOLBAR_HEIGHT - DEFAULT_COMBO_TEXTFIELD_HEIGHT) / 2, DEFAULT_POPOVER_WIDTH - (DEFAULT_COMBO_TEXTFIELD_MARGIN * 2), DEFAULT_COMBO_TEXTFIELD_HEIGHT)]; textField.delegate = self; textField.autocorrectionType = UITextAutocorrectionTypeNo; textField.autocapitalizationType = UITextAutocapitalizationTypeNone; textField.font = [UIFont systemFontOfSize:DEFAULT_COMBO_FONT_SIZE]; textField.borderStyle = UITextBorderStyleRoundedRect; textField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter; [textField addTarget:self action:@selector(fieldTextDidUpdate:) forControlEvents:UIControlEventEditingDidEnd]; containerViewController.view = containerView; popoverTable.tableView.dataSource = self; popoverTable.tableView.delegate = self; popoverTable.tableView.frame = CGRectMake(0, DEFAULT_TOOLBAR_HEIGHT, DEFAULT_POPOVER_WIDTH, [self.controlSelections count] * popoverTable.tableView.rowHeight); popoverController.popoverContentSize = CGSizeMake(DEFAULT_POPOVER_WIDTH, ([self.controlSelections count] * popoverTable.tableView.rowHeight) + DEFAULT_TOOLBAR_HEIGHT); popoverController.delegate = self; [toolbar addSubview:textField]; [containerView addSubview:toolbar]; [containerView addSubview:popoverTable.tableView]; optionPopoverController = popoverController; [popoverController presentPopoverFromRect:control.frame inView:control.superview permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES]; // If there's currently an object that's first responder, make it resign that status for (UIView *subview in self.control.superview.subviews) { if ([subview isKindOfClass:[UITextField class]]) { if ([subview isFirstResponder]) { [subview resignFirstResponder]; [[NSRunLoop mainRunLoop] runUntilDate:[NSDate dateWithTimeIntervalSinceNow:1]]; } } } [textField becomeFirstResponder]; } else if (self.itemControlType == ControlTypeButton) { // Don't need to do anything here. Caller passed in target and action. But in order to trigger delegate rowItemWasSelected this control type was added here. } } </code></pre>
