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)
{
}
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
NSLog(#"Returning num sections");
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
NSLog(#"Returning num rows");
return 5;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSLog(#"Trying to return cell");
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell =[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:CellIdentifier] ;
}
cell.textLabel.text = #"Hello";
NSLog(#"Returning cell");
return cell;
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSLog(#"Selected row");
}
- (void)viewDidLoad
{
[super viewDidLoad];
m_titleTable = [[UITableView alloc] init] ;
m_titleTable.dataSource = self;
m_titleTable.delegate = self;
m_titleTable.frame = CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height);
[self.view addSubview:m_titleTable];
// Do any additional setup after loading the view from its nib.
}
-(void)titleAction:(id)sender{
NSLog(#"Calling");
UIViewController* popoverContent = [[UIViewController alloc]
init];
TitleViewController *popoverView = [[TitleViewController alloc]initWithNibName:#"TitleViewController" bundle:nil];
popoverContent.view = popoverView.view;
//resize the popover view shown
//in the current view to the view's size
popoverContent.contentSizeForViewInPopover = CGSizeMake(150, 150);
//create a popover controller
self->popoverController = [[UIPopoverController alloc]
initWithContentViewController:popoverContent];
//present the popover view non-modal with a
//refrence to the button pressed within the current view
[self->popoverController presentPopoverFromRect:btn_title.frame
inView:self.view
permittedArrowDirections:UIPopoverArrowDirectionUp
animated:YES];
}
The tableview Crash error message
[__NSCFType tableView:cellForRowAtIndexPath:]: unrecognized selector sent to instance 0x6e7dca0
2012-08-28 14:17:10.539 Demo[2790:f803] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFType tableView:cellForRowAtIndexPath:]: unrecognized selector sent to instance 0x6e7dca0'
Your problem is that your view controller is being deallocated. You shouldn't be doing something like this:
UIViewController* popoverContent = [[UIViewController alloc]
init];
TitleViewController *popoverView = [[TitleViewController alloc]initWithNibName:#"TitleViewController" bundle:nil];
popoverContent.view = popoverView.view;
Assuming you are using ARC, your popoverView object will be deallocated. Also this is just incorrect. You should almost never instantiate a UIViewController, and definitely never assign one view controller's view instance to another ones!
Here's how I'd rewrite your titleAction: method:
TitleViewController *titleViewController = [[TitleViewController alloc]initWithNibName:#"TitleViewController" bundle:nil];
//resize the popover view shown
//in the current view to the view's size
popoverContent.contentSizeForViewInPopover = CGSizeMake(150, 150);
//create a popover controller
self.popoverController = [[UIPopoverController alloc]
initWithContentViewController:titleViewController];
//present the popover view non-modal with a
//refrence to the button pressed within the current view
[self.popoverController presentPopoverFromRect:btn_title.frame
inView:self.view
permittedArrowDirections:UIPopoverArrowDirectionUp
animated:YES];
The UIPopoverController, at least, should keep a strong reference to the titleViewController and prevent it from being deallocated.
PS I changed your "self->popoverController" to self.popoverController as the -> is not really correct for what you are trying to do. Dot notation makes explicit that you are setting a property on an object.
in viewDidLoad you allocates and initiates a UITableView and connect it to self. You don't have a UITableView? defined and connect in the nib? Without seeing your whole project my guess is that you have UITableViews - this is a problem but not necessarily the crash problem. Did you inherit from UITableViewController as base class?
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];
}
}
