I need to hide an UIImageView, from an action triggered by a UISwitch which is inside a popover.
I'm using this piece of code however it does nothing when tapping the UISwitch, probably because the UISwitch its inside a popover view.
This code works perfectly on iPhone, however on iPad does not work and the UIImageView does not hide. Why?
- (IBAction)toggleImage:(id)sender {
if ([sender isOn]){
self.myImage.hidden = NO;
} else {
self.myImage.hidden = YES;
}
}
UIImageView is connected to an outlet and UISwitch is connected to an outlet and action.
Please help, thank you.
Since the switch being interacted with is on the popover and the image view that we want to change is on the underlying (presenting) VC, the proper approach is to make the underlying VC a delegate of the popover.
// MyPopoverVC.h
#protocol PopoverDelegate <NSObject>
- (void)popover:(MyPopoverVC *)vc changedSwitchTo:(BOOL)on;
#end
#interface MyPopoverVC : UIViewController
#property (nonatomic, weak) id<PopoverDelegate>delegate;
// ...
#end
In the Popover VC's implementation (IMPORTANT: the switch's IBAction should be wired to the popover vc)...
- (IBAction)toggleImage:(UISwitch *)sender {
[self.delegate popover:self changedSwitchTo:sender.on];
}
In the presenting vc, declare it as conforming to that <PopoverDelegate> protocol. Before presenting the popover, initialize the delegate...
MyPopoverVC *myPopoverVC = [[MyPopoverVC alloc] init...
myPopoverVC.delegate = self;
Also in the presenting vc, implement the delegate protocol...
- (void)popover:(MyPopoverVC *) changedSwitchTo:(BOOL)on {
self.myImage.hidden = !on;
}

So, I have a HomeViewController (picture 1) with two buttons, one white and one blue. On the right bottom corner you can see a button which modally presents a SettingsViewController (picture 2), on this view controller there are 4 buttons so the user can choose which color scheme do they prefer. Imagine the user press the first one (red) then, when dismissing the view controller the color scheme of HomeViewController should look like picture 3.
Any ideas on how to do this on a efficiently/simple way?.
There are two good ways you could do this: 1) Delegation, and 2) viewWillAppear:.
For delegation, you'll need to define a protocol. Your HomeViewController will be a delegate for this protocol, and your SettingsViewController will call it.
//SettingsViewController.h
#protocol SettingsDelegate <NSObject>
#required
-(void)colorChanged:(UIColor *)color;
#end
#interface SettingsViewController : UIViewController
#property (nonatomic, weak) id<SettingsDelegate> delegate;
#end
Somewhere when the settings view controller is set up, make sure to set self.delegate equal to a reference to HomeViewController. This is a must.
Then, when your user changes the color, call:
[self.delegate colorChanged:whateverColor];
Your delegate must obviously observe this method, and change the color appropriately:
-(void)colorChanged:(UIColor *)color {
[myButton setBackgroundColor:color];
}
For viewWillAppear:, just save the color somewhere and set the color of your button in your view controller's method for this. viewWillAppear: will get called when your settings view is about to disappear and show the home view controller:
-(void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
[myButton setBackgroundColor:mySavedColor];
}
In HomeViewController
On SettigButton Click
{
Pass the HomeViewController delegate object SettingsViewController
Present your color Picker SettingsViewController
}
In SettingsViewController
Define protocol name SettingsViewControllerDelegate
{
-(void)selectedColor:(UIColor*)color;
}
return the selected color On dismissViewController
if(delegate)
{
[delegate selectedColor:color];
}
Again In HomeViewController
-(void)selectedColor:(UIColor*)color
{
view.backgroundColor=color;
}
I have a button on UIViewController on click of that button an UIview gets poped up like alertview which has tableview in it.Now on selection of table cell i would like to segue to the detail viewcontroller
Here's the link to which i refered but none of them worked for me
For alertview i have used (https://github.com/kwent/ios-custom-alertview)
Thanks.
#yar1vn's answer is right, however, I'll describe more precisely what you need to do.
Custom alert view from your link has a delegate property, which should conform to protocol
#protocol CustomIOS7AlertViewDelegate
- (void)customIOS7dialogButtonTouchUpInside:(id)alertView clickedButtonAtIndex:(NSInteger)buttonIndex;
#end
that means you should implement this method in your UIViewController.
in .h file:
#interface YourViewController : UIViewController <YourViewController>
...
#end
in .m file:
#implementation YourViewController
...
- (void)customIOS7dialogButtonTouchUpInside:(id)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
[self performSegueWithIdentifier:#"YourSegue" sender:nil];
}
and set the delegate when creating alertView:
[alertView setDelegate:self];
#"YourSegue" is the segue from the controller which shows alertView to the detail view controller.
I disagree that you should use UIAlertController, since if your deployment target is iOS 7 (which is reasonable) you should not use new features of iOS 8
EDIT:
if you want to launch segue from tap on table view cell, you should call [self performSegueWithIdentifier:#"YourSegue" sender:nil] from tableView's delegate method -tableView:didSelectRowAtIndexPath:
I assume you have set current view controller as tableView's dataSource and delegate, so add to your view controller
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[self performSegueWithIdentifier:#"YourSegue" sender:nil];
}
EDIT 2:
though setting the UIView as delegate is not the best approach, we can handle it :)
I see two solutions:
the first is to add the controller as the property to your view like this:
#interface YourView : UIView <UITableViewDelegate, UITableViewDataSource>
#property (nonatomic, weak) YourViewController *parentController;
...
somewhere (probably, in -viewDidLoad) you set this property as
youViewInstance.parentController = self;
and the in view's delegate method call
[self.parentController performSegueWithIdentifier:#"YouSegue" sender:nil]
the second one is to simply set the controller as tableView's delegate and call performSegue: from its method. And you should describe all details more completely :)
You shouldn't use 3rd party AlertViews anymore. You can use the AlertController provided with iOS 8 SDK.
I don't know how this AlertView works but the readme mentions a delegate. Did you try calling the segue from the delegate method?
in my application I have a UIView object in second view controller. Now I want to display the UIView as a popup or sub view when I click the button from first view controller. Please tell me how to do this? I have seen many solution for the nib files but I didn't find any for storyboard.
I have connected the IBOulet of view in my second view controller.
#property (strong, nonatomic) IBOutlet UIView *popview;
And i have imported the second view controller in my firstview please tell me how to make this one i have been stuck here for long time please help me out on this one.
Thanks.
In your FirstViewController which has UIView *popview:
- (void)viewDidLoad
{
[super viewDidLoad];
// you don't want to show PopView
self.popview.alpha = 0;
}
- (void) showPopView
{
//you want to show PopView
self.popview.alpha = 1;
}
Try Adding this in your code
-(void)viewDidLoad
{
popView.hidden=true;
}
and when ever user clicks an action change the hidden property to false just like
-(IBAction)AnyActionPerferformed:(id)sender
{
popView.hidden=false;
}
You can Learn about this from
https://developer.apple.com/library/ios/featuredarticles/ViewControllerPGforiPhoneOS/AboutViewControllers/AboutViewControllers.html
You don't need an extra UIViewController
In your storyboard, drag a new UIView to your view controller. (It will be your popup view)
Link to your view controller. (#property (strong, nonatomic) IBOutlet UIView *popview;)
When you want to hide popview set it's alpha to 0.
I am presenting a modal view using a storyboard segue set as Form Sheet.
The problem is, when I rotate the iPad after this view is displayed, the view is removed from the view/dismissed.
I have no idea why. It only seems to occur when starting in Portrait then rotating to Landscape.
If I start in Landscape then show the view then rotate it stays on the screen fine.
Any ideas?
EDIT ----
It also seems that full screen modal views are also dismissed after rotation!
There's nothing special going on in the presentation code, this is a full screen modal:
EditViewController *editView = [self.navigationController.storyboard instantiateViewControllerWithIdentifier:#"editViewController"];
editView.delegate = self;
editView.image = image;
editView.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentViewController:editView animated:YES completion:nil];
This happens on both iOS 6 and iOS 7
EDIT 2 ----
Forgot to mention, i'm presenting the modal from the left/master view controller of a UISplitViewController
late, but what it worked for me was just before
[self presentViewController:aController animated:YES completion:nil];
dismiss the master controller, adding this lines
[self.splitViewController setPreferredDisplayMode:UISplitViewControllerDisplayModePrimaryHidden];
[self.splitViewController setPreferredDisplayMode:UISplitViewControllerDisplayModeAutomatic];
and then present your controller
Get rid of: editView.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
That will solve the issue you are experiencing. Modal view controllers presented on iPad as a Form Sheet do not rotate correctly using that transition style.
its really hard to get the cause how and why this is happening as i found that this also happen with UIPopover also as when you rotate it UIPopover hide because ???
So if you want to keep your view then just call again your controller after rotation will do fine user experience
This is not a bug its a limitation on UISplitViewController. The problem exists when the masterViewController (which is a UIPopoverController) is able to be dismissed. Heres how it works with the assumption that your app does allow the masterViewController to be dismissed in portrait and does not allow in landscape.
In portrait while the masterViewController is visible, if you were to present a modal from a viewController in the masterViewController and then rotate to landscape, the modal would disappear in iOS7 and the app would not rotate in iOS8. iOS8 introduces a condition to prevent the bad experience of iOS7. iOS7 losses the modal in the process of moving the masterViewController from the popoverController to a contained viewController in the splitViewController.
The modal needs to be presented from the splitViewController and not from the masterViewController. The only problem with this is the modal gets presented below the masterViewController in portrait. My solution is to dismiss the masterViewController and then present the modal.
There are several ways to achieve this result depending on how complex your code needs to be. Here's how I do this in my app.
I first subclass UISplitViewController in order to have a reference to the popoverController. I use delegate forwarding in order to access the delegate methods internally and externally. Heres the .h
// MainSplitViewController.h
#import <UIKit/UIKit.h>
#interface MainSplitViewController : UISplitViewController
#property (nonatomic, weak, readonly) UIPopoverController* primaryColumnController;
#end
And the .m
// MainSplitViewController.m
#import "MainSplitViewController.h"
#interface MainSplitViewController () <UISplitViewControllerDelegate>
#property (nonatomic, weak) id<UISplitViewControllerDelegate> externalDelegate;
#property (nonatomic, weak) UIPopoverController* primaryColumnController;
#end
#implementation MainSplitViewController
- (instancetype)init {
self = [super init];
if (self) {
self.delegate = self;
}
return self;
}
#pragma mark - Split View Controller Delegate
- (void)splitViewController:(UISplitViewController *)svc popoverController:(UIPopoverController *)pc willPresentViewController:(UIViewController *)aViewController {
self.primaryColumnController = pc;
if ([(id)self.externalDelegate respondsToSelector:_cmd]) {
[self.externalDelegate splitViewController:svc popoverController:pc willPresentViewController:aViewController];
}
}
#pragma mark - Delegate Forwarder
- (void)setDelegate:(id<UISplitViewControllerDelegate>)delegate {
[super setDelegate:nil];
self.externalDelegate = (delegate != self) ? delegate : nil;
[super setDelegate:delegate ? self : nil];
}
- (BOOL)respondsToSelector:(SEL)aSelector {
id delegate = self.externalDelegate;
return [super respondsToSelector:aSelector] || [delegate respondsToSelector:aSelector];
}
- (id)forwardingTargetForSelector:(SEL)aSelector {
id delegate = self.externalDelegate;
return [delegate respondsToSelector:aSelector] ? delegate : [super forwardingTargetForSelector:aSelector];
}
#end
Next I create a class extension on UIViewController
// UIViewController+Popover.h
#import <UIKit/UIKit.h>
#interface UIViewController (Popover)
- (UIViewController *)popoverPresentingViewController;
#end
And the .m
// UIViewController+Popover.m
#import "UIViewController+Popover.h"
#import "MainSplitViewController.h"
#implementation UIViewController (Popover)
- (UIViewController *)popoverPresentingViewController {
UIViewController* viewController = self;
if ([self.splitViewController isKindOfClass:[MainSplitViewController class]]) {
viewController = self.splitViewController;
MainSplitViewController* mainSplitViewController = (MainSplitViewController *)self.splitViewController;
if (mainSplitViewController.primaryColumnController.popoverVisible) {
[mainSplitViewController.primaryColumnController dismissPopoverAnimated:YES];
}
}
return viewController;
}
#end
Now where ever you present the modal, instead of calling [self presentViewController: ... call [self.popoverPresentingViewController presentViewController: ...]. Remember to import UIViewController+Popover.h
your question came closest to my bug, On returning from modalView the parentView will switch to orientation in which the application was opened.
Visually it appears that the modal view is rotated and then returns.
I solved it by removing the modal view altogether, and using
[self.navigationController pushViewController: <the View(not modal now)>]
instead of using-
[self presentViewController:<Modal View>]
I think this is because the navigation controller doesn't own the Modal View, hence it reloads - when returning from the modal view - to incorrect orientation
Problem:
When presenting a view controller modally, it gets dismissed on rotation.
Approach:
Set the UISplitViewControllerDelegate
Use the UISplitViewControllerDelegate methods
Hold a reference to your modal view controller in an instance variable
Check if your modal view controller's presenting view controller exists.
If it exists, nothing needs to be done, else just present without any animation.
UISplitViewControllerDelegate methods:
func primaryViewController(forCollapsing splitViewController: UISplitViewController) -> UIViewController? {
if let someModalViewController = someModalViewController,
someModalViewController.presentingViewController == nil {
let masterViewController = viewControllers.first
masterViewController?.present(someModalViewController,
animated: false) {
}
}
return nil
}
func primaryViewController(forExpanding splitViewController: UISplitViewController) -> UIViewController? {
if let someModalViewController = someModalViewController,
someModalViewController.presentingViewController == nil {
let masterViewController = viewControllers.first
masterViewController?.present(someModalViewController,
animated: false) {
}
}
return nil
}
Note:
UISplitViewControllerDelegate has quite a methods, it can be daunting initially, if you spend some time experimenting, you can achieve what you want.
It has fine grained access.
I'm very late but try this. It works for me.
[self.splitViewController presentViewController:editView animated:YES completion:nil];
I've created a popover from a UIBarButtonItem using Xcode Storyboards (so there's no code) like this:
Presenting the popover works just fine. However, I can't get the popover to disappear when I tap the UIBarButtonItem that made it appear.
When the button is pressed (first time) the popover appears. When the button is pressed again (second time) the same popover appears on top of it, so now I have two popovers (or more if I continuer pressing the button). According to the iOS Human Interface Guidelines I need to make the popover appear on the first tap and disappear on the second:
Ensure that only one popover is visible onscreen at a time. You should not display more than one popover (or custom view designed to look and behave like a popover) at the same time. In particular, you should avoid displaying a cascade or hierarchy of popovers simultaneously, in which one popover emerges from another.
How can I dismiss the popover when the user taps the UIBarButtonItem for a second time?
EDIT: These problems appear to be fixed as of iOS 7.1 / Xcode 5.1.1. (Possibly earlier, as I haven't been able to test all versions. Definitely after iOS 7.0, since I tested that one.) When you create a popover segue from a UIBarButtonItem, the segue makes sure that tapping the popover again hides the popover rather than showing a duplicate. It works right for the new UIPresentationController-based popover segues that Xcode 6 creates for iOS 8, too.
Since my solution may be of historical interest to those still supporting earlier iOS versions, I've left it below.
If you store a reference to the segue's popover controller, dismissing it before setting it to a new value on repeat invocations of prepareForSegue:sender:, all you avoid is the problem of getting multiple stacking popovers on repeated presses of the button -- you still can't use the button to dismiss the popover as the HIG recommends (and as seen in Apple's apps, etc.)
You can take advantage of ARC zeroing weak references for a simple solution, though:
1: Segue from the button
As of iOS 5, you couldn't make this work with a segue from a UIBarButtonItem, but you can on iOS 6 and later. (On iOS 5, you'd have to segue from the view controller itself, then have the button's action call performSegueWithIdentifier: after checking for the popover.)
2: Use a reference to the popover in -shouldPerformSegue...
#interface ViewController
#property (weak) UIPopoverController *myPopover;
#end
#implementation ViewController
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
// if you have multiple segues, check segue.identifier
self.myPopover = [(UIStoryboardPopoverSegue *)segue popoverController];
}
- (BOOL)shouldPerformSegueWithIdentifier:(NSString *)identifier sender:(id)sender {
if (self.myPopover) {
[self.myPopover dismissPopoverAnimated:YES];
return NO;
} else {
return YES;
}
}
#end
3: There's no step three!
The nice thing about using a zeroing weak reference here is that once the popover controller is dismissed -- whether programmatically in shouldPerformSegueWithIdentifier:, or automatically by the user tapping somewhere else outside the popover -- the ivar goes to nil again, so we're back to our initial state.
Without zeroing weak references, we'd have to also:
set myPopover = nil when dismissing it in shouldPerformSegueWithIdentifier:, and
set ourself as the popover controller's delegate in order to catch popoverControllerDidDismissPopover: and also set myPopover = nil there (so we catch when the popover is automatically dismissed).
I found the solution here https://stackoverflow.com/a/7938513/665396
In first prepareForSegue:sender: store in a ivar/property the pointer to the UIPopoverController and user that pointer to dismiss the popover in the subsequent invocations.
...
#property (nonatomic, weak) UIPopoverController* storePopover;
...
- (void)prepareForSegue:(UIStoryboardSegue *)segue
sender:(id)sender {
if ([segue.identifier isEqualToString:#"My segue"]) {
// setup segue here
[self.storePopover dismissPopoverAnimated:YES];
self.storePopover = ((UIStoryboardPopoverSegue*)segue).popoverController;
...
}
I've used custom segue for this.
1
create custom segue to use in Storyboard:
#implementation CustomPopoverSegue
-(void)perform
{
// "onwer" of popover - it needs to use "strong" reference to retain UIPopoverReference
ToolbarSearchViewController *source = self.sourceViewController;
UIViewController *destination = self.destinationViewController;
// create UIPopoverController
UIPopoverController *popoverController = [[UIPopoverController alloc] initWithContentViewController:destination];
// source is delegate and owner of popover
popoverController.delegate = source;
popoverController.passthroughViews = [NSArray arrayWithObject:source.searchBar];
source.recentSearchesPopoverController = popoverController;
// present popover
[popoverController presentPopoverFromRect:source.searchBar.bounds
inView:source.searchBar
permittedArrowDirections:UIPopoverArrowDirectionAny
animated:YES];
}
#end
2
in view controller that is source/input of segue e.g. start segue with action:
-(void)searchBarTextDidBeginEditing:(UISearchBar *)searchBar
{
if(nil == self.recentSearchesPopoverController)
{
NSString *identifier = NSStringFromClass([CustomPopoverSegue class]);
[self performSegueWithIdentifier:identifier sender:self];
}
}
3
references are assigned by segue which creates UIPopoverController - when dismissing popover
-(void)searchBarTextDidEndEditing:(UISearchBar *)searchBar
{
if(self.recentSearchesPopoverController)
{
[self.recentSearchesPopoverController dismissPopoverAnimated:YES];
self.recentSearchesPopoverController = nil;
}
}

I solved it creating a custom ixPopoverBarButtonItem that either triggers the segue or dismisses the popover being shown.
What I do: I toggle the action & target of the button, so it either triggers the segue, or disposes the currently showing popover.
It took me a lot of googling for this solution, I don't want to take the credits for the idea of toggling the action. Putting the code into a custom button was my approach to keep the boilerplate code in my view to a minimum.
In the storyboard, I define the class of the BarButtonItem to my custom class:
Then I pass the popover created by the segue to my custom button implementation in the prepareForSegue:sender: method:
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([segue.identifier isEqualToString:#"myPopoverSegue"]) {
UIStoryboardPopoverSegue* popSegue = (UIStoryboardPopoverSegue*)segue;
[(ixPopoverBarButtonItem *)sender showingPopover:popSegue.popoverController];
}
}
Btw... since I have more than one buttons triggering popovers, I still have to keep a reference of the currently displayed popover and dismiss it when I make the new one visible, but this was not your question...
Here is how I implemented my custom UIBarButtonItem:
...interface:
#interface ixPopoverBarButtonItem : UIBarButtonItem
- (void) showingPopover: (UIPopoverController *)popoverController;
#end
... and impl:
#import "ixPopoverBarButtonItem.h"
#interface ixPopoverBarButtonItem ()
#property (strong, nonatomic) UIPopoverController *popoverController;
#property (nonatomic) SEL tempAction;
#property (nonatomic,assign) id tempTarget;
- (void) dismissPopover;
#end
#implementation ixPopoverBarButtonItem
#synthesize popoverController = _popoverController;
#synthesize tempAction = _tempAction;
#synthesize tempTarget = _tempTarget;
-(void)showingPopover:(UIPopoverController *)popoverController {
self.popoverController = popoverController;
self.tempAction = self.action;
self.tempTarget = self.target;
self.action = #selector(dismissPopover);
self.target = self;
}
-(void)dismissPopover {
[self.popoverController dismissPopoverAnimated:YES];
self.action = self.tempAction;
self.target = self.tempTarget;
self.popoverController = nil;
self.tempAction = nil;
self.tempTarget = nil;
}
#end
ps: I am new to ARC, so I am not entirely sure if I am leaking here. Please tell me if I am...
I have solved this problem with no need to keep a copy of a UIPopoverController. Simply handle everything in storyboard (Toolbar, BarButtons. etc.), and
handle visibility of the popover by a boolean,
make sure there is a delegate, and it is set to self
Here is all the code:
ViewController.h
#interface ViewController : UIViewController <UIPopoverControllerDelegate>
#end
ViewController.m
#interface ViewController ()
#property BOOL isPopoverVisible;
#end
#implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
self.isPopoverVisible = NO;
}
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
// add validations here...
self.isPopoverVisible = YES;
[[(UIStoryboardPopoverSegue*)segue popoverController] setDelegate:self];
}
- (BOOL)shouldPerformSegueWithIdentifier:(NSString *)identifier sender:(id)sender {
return !self.isPopoverVisible;
}
- (void)popoverControllerDidDismissPopover:(UIPopoverController *)popoverController {
self.isPopoverVisible = NO;
}
#end
I took rickster's answer and packaged it into a class derived from UIViewController. This solution does require the following:
iOS 6 (or later) with ARC
Derive your view controller from this class
make sure to call the "super" versions of prepareForSegue:sender and shouldPerformSegueWithIdentifier:sender if you are overriding those methods
Use a named popover segue
The nice thing about this is you don't have to do any "special" coding to support the proper handling of Popovers.
Interface:
#interface FLStoryboardViewController : UIViewController
{
__strong NSString *m_segueIdentifier;
__weak UIPopoverController *m_popoverController;
}
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender;
- (BOOL)shouldPerformSegueWithIdentifier:(NSString *)identifier sender:(id)sender;
#end
Implementation:
#implementation FLStoryboardViewController
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if( [segue isKindOfClass:[UIStoryboardPopoverSegue class]] )
{
UIStoryboardPopoverSegue *popoverSegue = (id)segue;
if( m_popoverController == nil )
{
assert( popoverSegue.identifier.length > 0 ); // The Popover segue should be named for this to work fully
m_segueIdentifier = popoverSegue.identifier;
m_popoverController = popoverSegue.popoverController;
}
else
{
[m_popoverController dismissPopoverAnimated:YES];
m_segueIdentifier = nil;
m_popoverController = nil;
}
}
else
{
[super prepareForSegue:segue sender:sender];
}
}
- (BOOL)shouldPerformSegueWithIdentifier:(NSString *)identifier sender:(id)sender
{
// If this is an unnamed segue go ahead and allow it
if( identifier.length != 0 )
{
if( [identifier compare:m_segueIdentifier] == NSOrderedSame )
{
if( m_popoverController == NULL )
{
m_segueIdentifier = nil;
return YES;
}
else
{
[m_popoverController dismissPopoverAnimated:YES];
m_segueIdentifier = nil;
m_popoverController = nil;
return NO;
}
}
}
return [super shouldPerformSegueWithIdentifier:identifier sender:sender];
}
#end
