- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSLog((#"This is didSelectRowAtIndexPAth"));
DetailViewController *detailViewController = [[DetailViewController alloc] init];
detailViewController.myDictionary = [self.placeArray objectAtIndex:[indexPath row]]
// This MyDictionary NSdictionary is declared in other viewController which is populated here ..

NSLog(#"My Dictionary: This is a MasterView two %#",detailViewController.myDictionary);
[self performSegueWithIdentifier:#"showDetail" sender:self];
}
Use PrepareForSegue for this purpose
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
DetailViewController * detailViewController = (DetailViewController*)segue.destinationViewController;
detailViewController.myDictionary = [self.placeArray objectAtIndex:index];
}
From did select just use the prepareForSegue method(Hope you have already used.) Set the presenting view controller option via xib or programmatically and just stop there.prepareForSegue will call automatically while presenting the view while using storyboard.
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
DetailViewController *detailViewController = [[DetailViewController alloc] init];
detailViewController.myDictionary = [self.placeArray objectAtIndex:[indexPath row]];
}
edit you did_select_method and try.

I am trying to set a dynamic NSString value each time a table cell is pressed in my app. I am able to pass the variable to my custom UINavigationController with the code below -
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
NSString *page = [menuItems objectAtIndex:indexPath.row];
[[segue destinationViewController] setGrabPage: page];
}
The problem is that grabPage only gets set in the NavigationController, and not the top view displayed within the navigation controller. How do I pass this value through to the top view?
If your destinationViewController is a UINavigationController, you should cast it into a UINavigationController and get the rootViewController of the navigation controller.
Cast it to the type of this first controller and you're good to go
EDIT: Added sample code
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
NSString *page = [menuItems objectAtIndex:indexPath.row];
UINavigationController *nav = (UINavigationController *)[segue destinationViewController];
MyViewController *vc = (MyViewController *)(nav.viewControllers[0]);
[vc setGrabPage: page];
}
The following code is in my menuViewController.m. Now I want to go to another view when touch on a specific cell. What should I do to go to contactViewController?(I am using storyboard)
storyboard image:
https://drive.google.com/file/d/0BwOYR2GMJ7l8U1lYYVFVTWVkOG8/edit?usp=sharing
code:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath: (NSIndexPath *)indexPath
{
NSString *CellIdentifier = [menuItems objectAtIndex:indexPath.row];
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
if(indexPath.row==2)
{
}
}
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
// Set the title of navigation bar by using the menu items
NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
UINavigationController *destViewController = (UINavigationController*)segue.destinationViewController;
destViewController.title = [[menuItems objectAtIndex:indexPath.row] capitalizedString];
if ( [segue isKindOfClass: [SWRevealViewControllerSegue class]] ) {
SWRevealViewControllerSegue *swSegue = (SWRevealViewControllerSegue*) segue;
swSegue.performBlock = ^(SWRevealViewControllerSegue* rvc_segue, UIViewController* svc, UIViewController* dvc) {
UINavigationController* navController = (UINavigationController*)self.revealViewController.frontViewController;
[navController setViewControllers: #[dvc] animated: NO ];
[self.revealViewController setFrontViewPosition: FrontViewPositionLeft animated: YES];
};
}
I want to go to another view when touch on a specific cell.
For this, I'd do it this way:
Step 1:
Drag from TableViewController to ContactViewController:
Step 2:
Select segue and specify the Segue Identifier (Show attributes Inspector tab in the right side bar)
I have named the Segue Identifier as SegueTestID
I chose Push as my style but it seems you might need Modal
And the corresponding code (in your MenuViewController.m) should be something like:
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
if (indexPath.row == 2) {
[self performSegueWithIdentifier:#"SegueTestID" sender:self];
}
}
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
//following lines needed only if you need to send some detail across to ContactViewController
if ([segue.identifier isEqualToString:#"SegueTestID"]) {
ContactViewController *destinationViewController = segue.destinationViewController;
destinationViewController.strTest = #"Check";
//where strTest is a variable in ContactViewController. i.e:
//"#property (nonatomic, strong) NSString *strTest;"
//declared in `ContactViewController.h`
}
//...
}
PS: It seems you have alot in your -prepareForSegue: already.
Obviously... you'll need to hook things up properly.
In Storyboard , Do this ( In your case its contactviewcontroller ) give the name identifier name to contactViewController whatever you want as shown in image for showRecipeDetail
and you can go to the contactviewcontroller
and then
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([segue.identifier isEqualToString:#"showRecipeDetail"]) {
NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
RecipeDetailViewController *destViewController = segue.destinationViewController;
destViewController.recipe = [recipes objectAtIndex:indexPath.row];
}
}
In above method it shows how to pass the data from current viewcontroller to destviewcontroller
where We simply set the property (i.e. recipeName) in the RecipeDetailViewController to pass the recipe name. Obviously, you can add other properties in the detail view controller to pass other recipe-related values. ( In your case it will be data you want to pass to contactviewcontroller)
When a segue is triggered, before the visual transition occurs, the storyboard runtime invokes prepareForSegue:sender: method of the current view controller. By implementing this method, we can pass any needed data to the view controller that is about to be displayed. Here, we’ll pass the selected recipe object to the detail view controller.
I am trying to go from a UITableView with prototype cells to a detailviewcontroller of the item I selected on.
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if([segue.identifier isEqualToString:#"historyToDetail"])
{
BYFHistoryDetailViewController *controller = (BYFHistoryDetailViewController *)segue.destinationViewController;
controller.workOut = [[BYFWorkOut alloc] init];
controller.workOut=_selectRow;
}
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
BYFHistoryTableViewController *detailViewController =[[BYFHistoryTableViewController alloc] init];
NSArray *items = [[BYFworkOutStore sharedStore] allItems];
BYFWorkOut *selectedItem = items[indexPath.row];
_selectRow = selectedItem;
}
What is not happening is the transition from the table to detail I have a push segue from the prototype cell to the details.
What am I missing?
You are doing quite a lot wrong here. When using segue's you don't create an instance of the class. You simply call:
[self performSegueWithIdentifier:#"MySegue" sender:self];
This will use the segue you have defined in the storyboard. Where MySegue is the segue ID you created.
When you want to pass in data you use the callback
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
BYFHistoryDetailViewController *vc = (BYFHistoryDetailViewController *)[segue destinationViewController];
vc.workOut = selectedItem;
}
But using this callback will mean you will need to store selectedItem somewhere after you click the row so you can access it here.
EDIT
Your code seems a bit odd here also.
You set workout to a new object.
detailViewController.workOut = [[BYFWorkOut alloc]init];
Create another object from data.
NSArray *items = [[BYFworkOutStore sharedStore] allItems];
BYFWorkOut *selectedItem = items[indexPath.row];
And then assign the new object, overwriting the previous one.
//give detail view controller a pointer to the item object in row
detailViewController.workOut = selectedItem;
There is no need to have the first line of code at all
EDIT 2
If you only going to be using the one selected item at a time. you can do this in your UITableViewController class.
#implementation MyTableViewControllerClass
{
BYFWorkOut *_selectedItem;
}
inside didSelectRowAtIndexPath:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSArray *items = [[BYFworkOutStore sharedStore] allItems];
_selectedItem = items[indexPath.row];
}
EDIT 3
I've modified the code you posted here. You didn't add the first line of code i posted. Please look at this:
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if([segue.identifier isEqualToString:#"historyToDetail"])
{
BYFHistoryDetailViewController *controller = (BYFHistoryDetailViewController *)segue.destinationViewController;
controller.workOut = _selectRow;
}
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSArray *items = [[BYFworkOutStore sharedStore] allItems];
_selectRow = items[indexPath.row];
[self performSegueWithIdentifier:#"historyToDetail" sender:self];
}
You need to name your segue and call the method:
[self performSegueWithIdentifier:#"MySegue" sender:self];
I have created a UITableView and set everything up so that it pulls the correct Data that I want on the table. The only issue I have is that when I click on an item, I want it to open that viewController
I have set the Storyboard ID up correctly so everything should work but please see my code below incase there's something obvious I've missed:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
// Navigation logic may go here. Create and push another view controller.
/*
<#DetailViewController#> *detailViewController = [[<#DetailViewController#> alloc] initWithNibName:#"<#Nib name#>" bundle:nil];
// ...
// Pass the selected object to the new view controller.
[self.navigationController pushViewController:detailViewController animated:YES];
*/
UIViewController *newTopViewController;
if (indexPath.section == 0) {
NSString *identifier = [NSString stringWithFormat:#"%#", [self.section1 objectAtIndex:indexPath.row]];
newTopViewController = [self.storyboard instantiateViewControllerWithIdentifier:identifier];
} else if (indexPath.section == 1) {
NSString *identifier = [NSString stringWithFormat:#"%#", [self.section2 objectAtIndex:indexPath.row]];
newTopViewController = [self.storyboard instantiateViewControllerWithIdentifier:identifier];
}
else if (indexPath.section == 2) {
NSString *identifier = [NSString stringWithFormat:#"%#", [self.section3 objectAtIndex:indexPath.row]];
newTopViewController = [self.storyboard instantiateViewControllerWithIdentifier:identifier];
}
}
I can provide more info if needed
You use instantiateViewControllerWithIdentifier to create view controller objects.
But you are not presenting the created view controller object so add:
[self.navigationController presentViewController:newTopViewController animated:YES completion:nil];
If Identifiers are correct and you set segues in your storyboard then you can just call
[self performSegueWithIdentifier:indentifier sender:nil];
You need to either Push yournewTopViewController
[self.navigationController pushViewController:newTopViewController animated:YES];
Or Modally Present your newTopViewController
[self.navigationController presentViewController:newTopViewController animated:YES completion:nil];
in the end of your didSelectRowAtIndexPath Method.
To answer your question I believe you should first import all your .h files First.
Then you can go
if (indexPath.section == 0) {
FirstViewController *firstController = [[FirstViewController alloc] init];
[self presentViewController:firstController animated:YES completion:nil];
}
And so on and so forth
I have a table with 5 cells and if the user clicks my second cell for example, I want to show another table or another page.
Is using
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath`
the way ?
Here is an example of navigating to another view controller when the user clicks on the second cell (assuming you have a navigation controller):
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
if(indexPath.row == 1){
MyViewController * vc = [[MyViewController alloc] init];
[self.navigationController pushViewController:vc animated:YES];
}
}
sample Link :http://www.tutorialspoint.com/ios/ios_ui_elements_tableview.htm
if (indexPath.row ==1)
{
//Second cell index path its move another class xib
classname *yourcontroller = [[classname alloc] initWithNibName:#"xib file name" bundle:nil];
yourcontroller.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
[self presentViewController:helpcontroller animated:YES completion:nil];
}
If you are using a Storyboard, you may skip tableView:didSelectRowAtIndexPath: and use prepareForSegue:sender: instead:
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([segue.identifier isEqualToString:#"__SEGUE_IDENTIFIER__"]) {
NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
SomeOtherViewController *vc = (SomeOtherViewController *)segue.destinationViewController;
// assign something to vc
}
}
