I've been trying to push a uiwebview from a tableview to no avail. This is the code I have right now and whenever I click the cell, it would crash and show me the error.
Courses.m
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
[tableView deselectRowAtIndexPath:indexPath animated:YES];
if ([[array objectAtIndex:indexPath.row] isEqual:#"GolfClub"])
{
Blue *changi = [[Blue alloc] initWithNibName:#"Golf Club" bundle:nil];
[self.navigationController pushViewController:changi animated:YES];
[changi release];
}
else if ([[array objectAtIndex:indexPath.row] isEqual:#"ExecutiveGolfCourse"])
{
ExecutiveGolfCourse *egc = [[ExecutiveGolfCourse alloc] initWithNibName:#"Executive Golf Course" bundle:nil];
[self.navigationController pushViewController:egc animated:YES];
[egc release];
}
newsClicked.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentModalViewController:newsClicked animated:YES];
}
initWithNibName is not meant for the title of your ViewController
nib name is actually the name of the .xib file that is associated with that ViewController

I'm trying to link cells from an UITableViewController to UIViewController, but each cell has to call a different UIViewController (so I imagine that I'll have to create one link to each view controller) and I don't know how to link them through storyboard.
This is what I have until now:
MainView.h
#interface MainView : UITableViewController <UITableViewDelegate, UITableViewDataSource>
{
NSArray *tableData;
}
#property (nonatomic, retain) NSArray *tableData;
#end
MainView.m
- (void)viewDidLoad
{
tableData = [[NSArray alloc] initWithObjects:#"1", #"2", #"3", #"4", nil];
[super viewDidLoad];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [tableData count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = nil;
cell = [tableView dequeueReusableCellWithIdentifier:#"MyCell"];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"MyCell"];
}
cell.textLabel.text = [tableData objectAtIndex:indexPath.row];
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
[tableView deselectRowAtIndexPath:indexPath animated:YES];
UIViewController *anotherVC = nil;
if (indexPath.section == 0) //here I've also tried to use switch, case 0, etc
{
if (indexPath.row == 0)
{
anotherVC = [[ViewForFirstRow alloc] init];
}
NSLog(#"anotherVC %#", anotherVC); // shows that anotherVC = ViewForFirstRow
[anotherVC setModalPresentationStyle:UIModalPresentationFormSheet];
[anotherVC setModalTransitionStyle:UIModalTransitionStyleFlipHorizontal];
[self.navigationController pushViewController:anotherVC animated:YES];
}
}
#end
So, when first row is selected and I didn't link UITableViewController to UIViewController (ViewForFirstRow), it shows a black screen.
If I link UITableViewController to ViewForFirstRow, it opens the view but without the effect I used in code [self.navigationController pushViewController:anotherVC animated:YES];, so it appears that it called the view due to the link and not because of the code [self.navigationController pushViewController:anotherVC animated:YES];
How can I call the view by code properly and what kind of link should I use in storyboard for that? Also, how can I link the UITableViewController to multiples UIViewController (ViewForFirstRow, ViewForSecondRow, ViewForThirdRow, etc).
Thanks!
First, you can't hook up segues from cell (in a dynamic table view) in the storyboard, you have to do it in code. The code should look like this:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
[tableView deselectRowAtIndexPath:indexPath animated:YES];
if (indexPath.row == 0) {
UIViewController *anotherVC = [self.storyboard instantiateViewControllerWithIdentifier:#"anotherVC"];
[self.navigationController pushViewController:anotherVC animated:YES];
}else if (indexPath.row == 1) {
UIViewController *someOtherVC = [self.storyboard instantiateViewControllerWithIdentifier:#"someOtherVC"];
[self.navigationController pushViewController:someOtherVC animated:YES];
}
}
You shouldn't be doing anything with indexPath.section since your table view only has one section.
In storyboard presenting another viewcontroller in modally manner then use this:
UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:#"MainStoryboard" bundle:nil];
Synergy *objSynergy = (Synergy *)[mainStoryboard instantiateViewControllerWithIdentifier:#"Synergy"];
[self presentModalViewController:objSynergy animated:YES];
Synergy is my controller name You can put here your controller name that you want to present.
Make changes with your requirement. And for different viewcontroller open from different row
Use this:
if (indexPath.section==0)
{
if (indexPath.row ==0)
{
}
}
I have a UITableViewController working just fine with all the content when I tap on one of the cells didSelectRowAtIndexPath is being call but doesn't go to the next UITableViewController. Here is my code:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
ViewHeadersController *detailViewController = [[ViewHeadersController alloc] initWithNibName:#"ViewHeadersController" bundle:nil];
NSArray *resultsData = [_response objectForKey:#"results"];
detailViewController.urlHeaders = [[resultsData objectAtIndex:indexPath.row] objectForKey:#"url"];
[self.navigationController pushViewController:detailViewController animated:YES];
}
I know didSelectRowAtIndexPath is responding because I see the output of the NSLog.
Any of you knows what is going on or why the uitablevicontroller is not switching to the next UITableViewController?
I'll really appreciate your help
I change the line where is navegationController:
ViewHeadersController *detailViewController = [[ViewHeadersController alloc] initWithNibName:#"ViewHeadersController" bundle:nil];
detailViewController.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
NSArray *resultsData = [_response objectForKey:#"results"];
detailViewController.urlHeaders = [[resultsData objectAtIndex:indexPath.row] objectForKey:#"url"];
[self presentViewController:detailViewController animated:YES completion:nil];
In my Application i was using the different UIButtons as menue to Go Next class ,here is my Code
-(IBAction)GoToALevel
{
ALevel *obj = [[ALevel alloc] initWithNibName:#"ALevel" bundle:nil];
[self.navigationController pushViewController:obj animated:YES];
[obj release];
}
-(IBAction)GoToTLevel
{
TLevel *obj = [[TLevel alloc] initWithNibName:#"TLevel" bundle:nil];
[self.navigationController pushViewController:obj animated:YES];
[obj release];
}
-(IBAction)GoToNLevel
{
NLevel *obj = [[NLevel alloc] initWithNibName:#"NLevel" bundle:nil];
[self.navigationController pushViewController:obj animated:YES];
[obj release];
}
-(IBAction)GoToFLevel
{
FLevel *obj = [[FLevel alloc] initWithNibName:#"FLevel" bundle:nil];
[self.navigationController pushViewController:obj animated:YES];
[obj release];
}
Now i put all these catogories in UITableview.But can any one Guide me that how can get the Alevel when i click on first section of uitableview and so on .
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
here is problem how to go next class
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath*)indexPath
{
switch (indexPath.row) {
case 0:
[self GoToALevel];
break;
case 1:
[self GoToTLevel];
break;
case 2:
[self GoToNLevel];
break;
case 3:
[self GoToFLevel];
break;
default:
break;
}
}
hope this helps. happy coding :)
You will have to write this code in DidSelectRowAtIndexPath(). i.e
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath.
Here you can specify the action according to the method. Before this use the
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
to specify the what happens at the index of each cell i.e. indexpath.row.
I created app that have tableView with a viewController, what it should do is after selecting an item move to the second viewController and open it with passed data. I am implementing the next thing in the RootTableView:
(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
NSString *selecteditem = [listOfItems objectAtIndex:indexPath.row];
DetailViewController *dvController = [[DetailViewController alloc] initWithNibName:#"DetailView" bundle:[NSBundle mainBundle]];
dvController.selectedItem = selectedItem;
[self.navigationController pushViewController:dvController animated:YES];
[dvController release];
dvController = nil;
}
this code should work basicly but after I am selecting an item its been selected(blue colored) and that it, its stays with the selected blue color and nothing happened...after i selecting another row the same thing happens, what's wrong with my code?
You simply need to disable the selection styling when adding cells to your table:
cell.selectionStyle = UITableViewCellSelectionStyleNone;
just put following code into your code
[self.tableView deselectRowAtIndexPath:
[self.tableView indexPathForSelectedRow] animated:YES];
like i.e
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
NSString *selecteditem = [listOfItems objectAtIndex:indexPath.row];
// implement my code
[tableView deselectRowAtIndexPath:[tableView indexPathForSelectedRow] animated:YES];
DetailViewController *dvController = [[DetailViewController alloc] initWithNibName:#"DetailView" bundle:[NSBundle mainBundle]];
dvController.selectedItem = selectedItem;
[self.navigationController pushViewController:dvController animated:YES];
[dvController release];
dvController = nil;
}
I think you should check the navigationController. It might be not initialized.
You must have a UINavigationController to push any controller inside.
Hello I am trying to push different nibfiles into view
When you click On the uitablecell it corresponds to.
I have no Idea where to start.
Read UITableView class and navigation based app and see this code
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
//and code like this
if(indexPath.row==0)
{
FirstController *objFirstController=[[[FirstController alloc] initWithNibName:#"FirstView" bundle:nil] autorelease];
[self.navigationController pushViewController:objFirstController animated:YES];
}
else
{
SecondController *objSecondController=[[[SecondController alloc] initWithNibName:#"SecondView" bundle:nil] autorelease];
[self.navigationController pushViewController:objSecondController animated:YES];
}
}
