I'm attempting to navigate from on view controller to another but when I preform the segue I get the following un caught exception:
Terminating app due to uncaught exception 'CALayerInvalidGeometry',
reason: 'CALayer position contains NaN: [305 nan]'
I'm using the following code to do the segue:
[self performSegueWithIdentifier:#"goToGameFromIntro" sender:self];

I'm setting image to a UIImageView using in the below code
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
for(int i=0;i<[radioButtons count];i++){
[[radioButtons objectAtIndex:i] setImage:[UIImage imageNamed:#"checkbox_unchecked.png"]];
}
UIImageView *imageViews=(UIImageView *)[self.view viewWithTag:indexPath.row];
[imageViews setImage:[UIImage imageNamed:#"checkbox_checked.png"]];
}
So on clicking any tableview cell the images gets sets. But once if I click on objectatindex:0
then the app crashes. I'm unable to fix this.
Below is the crash log:

I think you are not getting UIImageView Object,you are getting uiview types object that's why it crashes. you should try to Define another tag property like 999+indexPath.row. Got it somewhere you define the tag=0 or IB automatically takes tag=0 to all object so it taking uiview with tag 0 not uiimageView
this means that you are sending message -(void)setImage to UIView, not to UIImageView. Make sure that view with tag indexPath.row and all radioButtons in array are actually UIImageView
I have table view with customize cell . I have 100 images on table view . When i run the application all images are get loaded on the table view .I can also scroll from top to bottom till 100th element. But while scrolling from bottom to to got the following exception at the somewhere at the middle at the fixed element :

i have following code for table view:
NSArray *objects=[[NSBundle mainBundle]loadNibNamed:#"CustomCell" owner:self options:nil];
NSLog(#"count =%d" ,[objects count]);
CustomCell *cell=[objects objectAtIndex:0];
Resource *r=[setUpArray objectAtIndex:indexPath.row];
cell.cellImage.image=[UIImage imageWithContentsOfFile:[library getResource:r.key]];
I am loading nib name of customize cell accurately.Please give me some solution.
I am using the scrollToRowAtIndexPath to center my tableview on the previously selected cell, however its crashing the app while testing on the phone but not on the emulator.
This is how I set it up
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
//Center previously selected cell to center of the screen
[self.tableView reloadData];
[self.tableView scrollToRowAtIndexPath:oldCheckedIndexPath atScrollPosition:UITableViewScrollPositionMiddle animated:NO];
}
And this is the error its giving
*** Terminating app due to uncaught exception 'NSRangeException', reason: '-[UITableView scrollToRowAtIndexPath:atScrollPosition:animated:]: section (0) beyond bounds (0).'
*** First throw call stack:
(0x31fe88bf 0x31d581e5 0x31fe87b9 0x31fe87db 0x32b6df1f 0x29bef 0x32ae26b5 0x32b3daf1 0x32afed21 0x32afea71 0x32afe78b 0x32afe4ff 0x32ab581b 0x32abafb9 0x3193aba7 0x3273be8d 0x31fbb2dd 0x31f3e4dd 0x31f3e3a5 0x3204afed 0x32ace743 0x34f5 0x2f70)
terminate called throwing an exception(gdb)
The thing being is I set
[self.tableView reloadData];
[self.tableView scrollToRowAtIndexPath:oldCheckedIndexPath atScrollPosition:UITableViewScrollPositionMiddle animated:NO];
in a different method the application works fine but dose not scroll to the index position..
I dont know how to fix it.

You probably don't need to reload data - just run your scrollToRowAtIndexPath after a delay:
[self performSelector:#selector(methodThatCallsScrollToRow) withObject:nil afterDelay:2.5];
Give the table a chance to load.
I have an NSObject set up to control various elements on my screen.
I initialize the class inside my View Controller like this:
self.pageSetupClass = [[PageSetup alloc] set:self.pageID];
In IB I have added my NSObject object and linked a button to an IBOutlet on it. I've also linked it to an IBAction found in the object. When I click this button the app crashes and I get this error:

terminate called after throwing an instance of 'NSException'
There is nothing in the function at the moment so it must be the calling that crashes it...right?
If you need me to post more code I certainly can. If you have any ideas I'm all ears. Thank You
Edit:
This is the contents of the function set called out when I initialize the PageSetup object:
-(PageSetup*) set:(int) i {
self = [super init];
if(self) {
self.iD=i;
self.pageSetupFile = [[NSBundle mainBundle] pathForResource:#"PageSetup" ofType:#"plist"];
self.pageSetupArray = [[NSMutableArray alloc] initWithContentsOfFile:self.pageSetupFile];
self.pageInfo = [self.pageSetupArray objectAtIndex:self.iD];
[self initializeSoundBytes];
[self initializeAnimations];
[self initializeToys];
NSLog(#"Page Setup Initializing: %#", self.pageInfo);
return self;
}
return self;
}
Another Edit:
I set my set function to return (void) and no longer initialize it using init.
I now receive this error message:

terminate called after throwing an instance of 'NSException'
Final Edit:
I had forgotten to connect my NSObject to the File's Owner in IB.
Could it be that when I reinitialize
this object...
Wait... what? In Objective-C you never call init* methods more than once.
In any case, the underlying problem appears to be a straightforward memory management issue. Something is being released before its time and it just so happens that a dictionary lands at that location. Turn on zombie detection and it'll likely catch the problem.
self.pageSetupClass = [[PageSetup alloc] set:self.pageID];
What does set: return? Is that a method of your PageSetup class? Does it return self?
Because apparently you're assigning pageSetupClass to whatever set: returns...
Unless set: returns self, you should try this:
self.pageSetupClass = [[PageSetup alloc] init];
[self.pageSetupClass set:self.pageID];
Edit:
ok, if you added the object in IB, the object was already instantiated for you when you loaded the nib, and the IBAction and IBOutlet connections have already been made.
When you do self.pageSetupClass = ..., you're setting pageSetupClass to a new instance, and that probably leaves the button with a bad target for its IBAction.
If the object was instantiated from the nib, and you have a reference to it in pageSetupClass from a IBOutlet, then just set whatever you want in the object, no need to alloc a new one.
I'm creating an iPad app, and I have two classes: NWRootViewController : UITableViewController and UINewFeedViewController : UIViewController. In NWRootViewController I have an UIBarButtonItem, which, when tapped, pops up a modal view controller called NWNewFeedViewController:
// THIS CODE IS IN NWROOTVIEWCONTROLLER.M
// New Feed
-(IBAction)showNewFeedViewAction:(id)sender {
[newFeedViewController setModalPresentationStyle:UIModalPresentationFormSheet];
[self presentModalViewController:newFeedViewController animated:YES];
}
This works fine. However, in the NWNewFeedViewController's view, I have another UIBarButtonItem which does this when tapped:
// THIS CODE IS IN NWNEWFEEDCONTROLLER.M
// Buttons
-(IBAction)cancelAction:(id)sender {
[self dismissModalViewControllerAnimated:YES];
}
When I tap this button, the app crashes with:

Can anyone help me? Thanks
Your cancel button has a target of your detail controller; you meant to target your new feed controller. So check how you configured the cancel button.
Your app is trying to call an object that has already been released. Enable zombie objects as explained here to find out what object is trying to be accessed.
