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'm testing my application on different devices. The app works fine on my iPhone 5, however, when I test it on my iPod touch 4g, I get this eror:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** [__NSArrayMinsertObject:atIndex:]: object cannot be nil'

The code that's crashing is this one:
/********/
NSMutableArray *titulosCampoTextArray = [[NSMutableArray alloc] init];
for (int i = 0; i < campos.count; i++) {
SignupCell *cell = (SignupCell*)[self.tableView cellForRowAtIndexPath:[NSIndexPath indexPathForRow:i inSection:0]];
[titulosCampoTextArray addObject:cell.textField.text];
}
/********/
I'm using custom prototype cells (SignupCell.h), on a UITableView inside a UIView.
Can't find the error, or how to fix it.
EDIT: Both devices are running iOS 6.1.3, and I'm using Xcode 4.6.1.
UITableView's -cellForRowAtIndexPath: method returns nil if the cell isn't visible on screen when you call it.
My guess is that on the iPhone 5 your table can display all rows at once, while on the shorter iPod touch, the last one or two cells aren't visible and -cellForRowAtIndexPath: thus returns nil, which makes your app crash.
You shouldn't rely on -cellForRowAtIndexPath to request model data! Your view controller is responsible for the data, not the table view.
Use the same way to access the model data like you do for setting the table view cells' text in the -tableView:cellForRowAtIndexPath: data source method of your view controller.
Just do this:
NSMutableArray *titulosCampoTextArray = [[NSMutableArray alloc] init];
for (int i = 0; i < campos.count; i++) {
SignupCell *cell = (SignupCell*)[self.tableView
cellForRowAtIndexPath:[NSIndexPath indexPathForRow:i inSection:0]];
if (cell.textField.text) {
[titulosCampoTextArray addObject:cell.textField.text];
}
}
I don't know why you apparently can add nil on an iPhone 5 but not on an iPod. It may be that for some other reason you just never happen to have a nil value for cell.textField.text when your app is running on the iPhone 5.
When I try with the following coding for custom cell, Its showing error.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = #"SimpletablcellCell";
SimpletablcellCell *cell = (SimpletablcellCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil)
{
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"SimpletablcellCell" owner:self options:nil];
cell = [nib objectAtIndex:0];
}
cell.nameLabel.text = [ar objectAtIndex:indexPath.row];
cell.thumbnailImageView.image = [UIImage imageNamed:[ar1 objectAtIndex:indexPath.row]];
cell.prepTimeLabel.text = [ar objectAtIndex:indexPath.row];
return cell;
}

Please check, what is wrong with this code?
Does a .nib / .xib exist in your project named SimpletablcellCell? You might have a typo in the name, please check carefully.
Make sure the file is part of your target. You can check this by opening the right-side menu in Xcode. Example:
If the cell exists, is it being copied in the build process? Check the "Copy bundle resources" phase in your project target build settings and make sure it is being copied. If not, add the file manually to this phase.
I had this problem when using Cocoapods for a private pod library of mine.
I had incorrectly included my xib files in s.source_files like so
s.source_files = 'MyLibrary/**/*.{h,m,xib}' //DOES NOT WORK
The solution was to use the resources attribute:
s.resources = 'MyLibrary/**/*.{xib}' //PROBLEM SOLVED
s.source_files = 'MyLibrary/**/*.{h,m}'
...
Then there is the problem that occurs if your podspec is looking for the xib as specified by s.resources above, but the xib is not in that path.
Once I mistakingly added a xib to my root project directory (where your AppDelegate is) and so Cocoapods would not copy it to any clients using the pod.
I fixed this by either changing the s.resources path or moving the xib so that it would be in the s.resources path.
If you are registering the nib using:
let nib: UINib = UINib(nibName: "myNib", bundle: nil)
tableView.registerNib(nib, forCellReuseIdentifier: "myCell")
make sure it is done in the viewDidLoad() function. I had placed it in the init() function and received this error. Once moved to viewDidLoad(), it worked well.
This error can occur when you rename some files outside XCode. To solve it you can just remove the files from your project (Right Click - Delete and "Remove Reference") You re-import the files in your project and everything will be ok !
Make sure your custom cell is added to the target you are building. Register that cell without fail.
There should be no IBOutlet errors in xib. Also, connect the view to the file owner.
The common error could be the name of the nib you are loading is incorrect.
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:
2012-08-20 16:25:36.321 EventApp[2422:12503] -[UIView setImage:]: unrecognized selector sent to instance 0x79642b0

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 am developing an app that presents chat messages in a table. But, this chat can't be started by the user, when the user receives a message the chat view opens. So, I made this code:
- (void) newMessageReceived:(NSMutableDictionary *)message
{
General *general = [General sharedManager];
NSString *firstmessage=[message objectForKey:#"msg"];
NSString *from=[message objectForKey:#"sender"];
NSArray *listItems = [from componentsSeparatedByString:#"#"];
NSString *fromsplit=[listItems objectAtIndex:0];
general.firstmess=firstmessage;
general.firstfrom=fromsplit;
NSLog(#"Mensaje recibido: %# de %#", [message objectForKey:#"msg"], fromsplit);
ChatViewController *cvc=[[ChatViewController alloc]initWithNibName:#"Chat" bundle:nil];
[[self navigationController]pushViewController:cvc animated:YES];
}
Everything is ok, until here. The ChatViewController extends UITableViewController. But, when a message is received i get the following exception:
Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-[UITableViewController loadView] loaded the "Chat" nib but didn't get a UITableView.
Then, i try to change the class extended to UIViewController (did this to check that the program enters the numberOfRowsInSection method) and then i receive:
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[ChatViewController setTableViewStyle:]: unrecognized selector sent to instance 0x9863200'
I think that solving the first exception would fix my problem. Any help?
Thank you.
In the second exception i think you have called [self setTableViewStyle:] method, while
you have made it UIViewController.
So try to call this method by tableViewOutlet.
[tableView setTableViewStyle:];
Hope this will help you
Solved it. i click the .xib file, under "objects", clicked "View". And then, in the Identity Inspector (the third one, starting from the left), in Custom Class, set it to UITableView. It was simply "View" before. And then, everything worked fine.
I have a uitableview 'A' which has cells, on clicking one of the cell, it needs to push another table view 'B'. and now when a cell is clicked in 'B', its needs to open a simple view.
I have managed to display both the tables in two different views. but when a cell is clicked in the menu B. it hangs and shows the below message
> unrecognized selector sent to > instance
could someone please tell me how do i solve this.thanks
Please find below my code
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
NSInteger row = [indexPath row];
NSLog(#"entering the if loop libdecripviewcontoller");
if(self.libraryDescripViewController == nil){
NSLog(#"its creating new instance of libdecripviewcontoller");
LibraryDescripViewController *aLib = [[LibraryDescripViewController alloc] initWithNibName:#"LibraryDescripView" bundle:nil];
self.libraryDescripViewController = aLib;
[aLib release];
}
libraryDescripViewController.title = [NSString stringWithFormat:#"%#",[libraryMenu objectAtIndex:row]];
ULS1AppDelegate *delegate = [[UIApplication sharedApplication] delegate ];
[delegate.searchLibNavController pushViewController:libraryDescripViewController animated:YES];

You can get more information about where the error is happening by opening your debugger window, clicking on "Show Breakpoints", and setting the following two breakpoints:
[NSException raise]
objc_exception_throw
Now when your app is about to crash, the debugger will usually show you exactly what line of code is causing the problem.
For this reason, it's good practice to have these breakpoints on every app you are developing.
It seems that you are calling "self.libraryDescripViewController = aLib" which is another way of writing [self setLibraryDescripViewController:alib].
The most likely cause of this would be in that you haven't declared the method setLibraryDescripViewController in your class.
Hope this helps.
There is way too little information here to diagnose exactly whats causing this, but one thing is certain. The method you are sending to the object is not defined for that object. Please post the code thats causing the error and the .h and .m files for the simple view you are talking about.
You probably need to set the class of the view controller in IB to LibraryDescripViewController. Double click the LibraryDescripViewController.xib file in xcode and when IB opens, in the identity view of the file's owner set the class to LibraryDescripViewController
