I implemented SWRevealController in my application. It has two segues one for slideviewcontroller and viewcontroller.
My slideviewcontroller is UITableViewController, I created a new class MenuTableViewController for use as a custom class of that siderbar(slideview). When I add a MenuTableViewController as a custom class of that view, it isn't shown when i slide a menu. If i leave it blank it's shown.
The problem is that I want when cell clicked to perform segue identifier or a button clicked, but I don't know where to implement them.
You can implement your segue in your tableview's delegate method:
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[self performSegueWithIdentifier:#"YourSegueIdentifier" sender:self];
}
You can segue to a proper ViewController depending on indexPath of the selected item inside of that method. Then implement your:
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([segue.identifier isEqualToString:#"YourSegueIdentifier"])
{
DestinatinoVCClass *destinationVC = (DestinatinoVCClass *)segue.destinationViewController;
//here you can set any public properties of the destinationVC
}
}
But in general, as far implementing SWRevealController into your app goes here is a full tutorial.

I have a problem.
I have a ViewController embed in navigationController.
And use the storyBoard to add the tableView in this viewController.
then,I add the segue.
Finally,I click the cell that the next viewController show twice.
I don't know how to fix it.
Thanks!
This is my code:
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
if(indexPath.row == 2){
[self performSegueWithIdentifier:#"showAdd" sender:self];
}
}
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
if ([segue.identifier isEqualToString:#"showAdd"]) {
AddCommentViewController *AddCommentVC = segue.destinationViewController;
AddCommentVC.CommentString = _DetailString;
}
}
You have to add the segue between both the UIViewController, not with the cell and UIViewController, as you have connected that segue on click of cell and you are calling the segue manually also that's why it is showing twice.
Do one thing, remove the segue and connect it between UIViewControllers then it will called only once.
i have a tableview and i want to when I touch on the cells to be navigate to the editViewController and when I Long touch (touch and wait) on the cells to be navigate to the DetailsViewController.
I got the answer to this question here.
now i have another problem, i use following code to pass selected row to detailViewContoler
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
if([[segue identifier] isEqualToString:#"ContectDetails"])
{
//get selected contact
NSManagedObject *selectedContact=[contacts objectAtIndex:[[self.tableView indexPathForSelectedRow] row]];
//pass selected contact to MyContactAppViewController for editing
ContactDetailsViewController *destViewcontroller=segue.destinationViewController;
destViewcontroller.contact=selectedContact;
//contact is my core data object
}
}
now i need to creat a modal segue and set segue identifier to "ContectDetails" in long press method.
Create a segue in storyboard between your table view's view controller and the ContactDetailsViewController and name it in the attributes inspector (let's say you name it 'ContactDetailsModalSegue').
Then in the gesture recognizer handler method you can call the segue like this:
-(void)handleLongPress:(UILongPressGestureRecognizer *)gestureRecognizer {
[self performSegueWithIdentifier:#"ContactDetailsModalSegue"
sender:self];
}
In this case self should be the view controller that your table view resides in. If you are handling the long press inside the table view cell class, then you should keep a weak reference to the table view's view controller and refactor accordingly:
In your table view cell's .h file include a pointer to the parent vc:
#property (weak, nonatomic) UIViewController *vc;
Make sure you pass a reference to the cell when you set it up in the table view delegate:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"MyIdentifier"];
cell.vc = self; //Assuming your datasource is in the view controller file (adjust if necessary)
}
and finally in the tableview cell's .m file, use the pointer to the vc to call the segue:
-(void)handleLongPress:(UILongPressGestureRecognizer *)gestureRecognizer {
[self.vc performSegueWithIdentifier:#"ContactDetailsModalSegue"
sender:self];
}
Update:
In order to pass a reference to the data that was used to populate the table view cell to the destinationViewController, you can do the following:
First, ensure that the data is stored in a model object in your custom table view cell subclass .h file. For this example I am using an NSManagedObject because thats what is in your question, but others reading this can swap this out with any model object (e.g. an NSObject subclass):
#property (strong, nonatomic) NSManagedObject *managedObject;
Note that in the performSegueWithIdentifier: method call you are passing a reference to self as the sender parameter. The object you specify for the sender parameter will be passed as an argument to the - (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender method. This enables you to retrieve the public property you just added to your custom table view cell, like this:
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
//Verify segue identifier
if([[segue identifier] isEqualToString:#"ContactDetailsModalSegue"])
{
//Protect yourself from unrecognized selector errors in case you reuse this segue
if ([sender isKindOfClass:[YourCustomTableCellClass class]] &&
[segue.destinationViewController respondsToSelector:#selector(setContact:)]) {
//get selected contact
NSManagedObject *selectedContact= (YourCustomTableCellClass *)sender.managedObject;
//pass selected contact to ContactDetailsViewController for editing
ContactDetailsViewController *destViewController= segue.destinationViewController;
destViewController.contact = selectedContact;
}
}
}
replace [self.navigationController pushViewController:detailView animated:YES]; with [self.navigationController presentModalViewController:detailView animated:YES completion:nil]; in the method
-(void)handleLongPress:(UILongPressGestureRecognizer *)gestureRecognizer
{
}
I want to create table, and when click cell in table , the content will display in another view. Each of table has different design. How do I do that.
I don't enough to post image, you can see in this link. thanks.
Use this delegate method:
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[self performSegueWithIdentifier:#"InstructionToSection" sender:nil]; //"InstructionToSection" is seque name
}
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
InstructionSectionViewController * instructSection = [segue destinationViewController]; // InstructionSectionViewController is ur next viewcontroller. 1st u need to import your destination viewcontroller in header
instructSection.SelectedItem = #"Ur Passing value"; // selectedItem should be declare in InstructionSectionViewController as property, need to synthesize
}

I'm totally lost in this issue. I have been working with storyboards, I have created a navigation controller with tableviews and some stuff. There are Services in each row of the tableview and I need to create one detail view for each service.
There are a lot of services, so I can't create them in the storyboard. The idea is to download the Services from a webservice (number of parameters, types of each one, etc..) and add as textfields / buttons as appropriate to the Service.
So, my problems and questions are:
1) Can I combine Storyboards and views programmatically? When I create a NewView in MyTableviewClass, should I do it in my prepareforsegue method? How can I show it in the screen without loosing my navigation controller? this is what I have (it doesn't work: it says to me that there is no segue with name 'Service1' ) :
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
if ([[segue identifier] isEqualToString:#"NextLevel"]) {
[segue.destinationViewController setActualNodo:[actualNodo getSonAtIndex:indexPath.row]];
} else if ([[segue identifier] isEqualToString:#"Service1"]) {
CGRect bounds = self.view.bounds;
UIView *myview = [[UIView alloc] initWithFrame:bounds];
[myview setBackgroundColor: [UIColor redColor]];
[self.view addSubview:myview];
[self.view bringSubviewToFront:myview]; }
Any book or reference is welcomed but I couldn't find anything similar. Is this very complicated in iOS? I have done a similar thing in Java. I have read about generating interfaces dynamically with XIBs but, sincerely, I don't know what it is..
Thanks for all.
Yes you can create a StoryBoard with a view and then add views programmatically to it.
You should not try creating a view within your prepareForSegue method. This really should be used for passing objects to another ViewController.
I would suggest this to you. Go back to your StoryBoard and create a new UIViewController scene. Click on your first scene and CTRL drag to the new scene. Next, click on your segue and give it a name.
Step 1:
Create a new class called ServicesViewController and make sure it's a subclass of `UIViewController:
Step 2:
Go back to your StoryBoard and click on scene so that it is selected. Next, click on the Files Owner and finally click on the class info button (the third button) and finally select your ServiceViewController class you just created.
Step 3:
Back in your ServicesViewController in the didSelectRowAtIndex method call your seque:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[self performSegueWithIdentifier:#"YOUR_SEGUE_NAME" sender:nil];
}
For now, clean out all the code in your prepareForSegue method and just get the transition down first.
In addition to Flea's answer, if you need to keep the navigation controller, just create a push segue in your storyboard by control dragging from the file owner icon (the yellow box under your view controller's view) of the table view controller to the ServiceViewController you added to the storyboard, this should show a popup window where you can select "push" as the type of the segue. Next, select the segue and in the attribute inspector (the fourth button, next to the one in the snapshot) and in the "Identifier" text field type in a unique identifier for your segue, such as serviceSegue.
At this point, using Flea's code:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[self performSegueWithIdentifier:#"serviceSegue" sender:nil];
}
And in the code you posted:
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
if ([[segue identifier] isEqualToString:#"serviceSegue"])
[segue.destinationViewController setActualNodo:[actualNodo getSonAtIndex:indexPath.row]];
}
I'm not sure what you are trying to do with the other segue "Service1", but if you want to change the view of the TableViewController, segues are not the way to do it. If anything you should do it in the didSelectRowAtIndexPath method depending on the row selected:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
if (You want to transition to other view controller)
[self performSegueWithIdentifier:#"serviceSegue" sender:nil];
else
Change your view here.
}
I hope this helps!
It sounds like you just have multiple cells in a tableView. Instead of using segues you can simply create different cells with different identifiers and show or hide them based on what services are detected in your services array which is populated from your web service.
I'm new to iOS development and don't get on well with storyboard.

I have got the push segue working now. But only pushing from the first tableViewController to the second one is animated and pushing back isn't animated.
In the first tableViewController:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[self performSegueWithIdentifier:#"xxx" sender:self];
}
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([segue.identifier isEqualToString:#"xxx"]) {
// set some properties of segue.destinationViewController
}
}
the second one is not modified.
Update:
I deleted the storyboard, did all of them programmatically and now everything works well.
Sometimes storyboard is just so confusing...
Whether the segue is animated will depend on how you do it. Try:
[self.navigationController popViewControllerAnimated:YES];
