New in iOS, here is Question:
I am using xcode 4.0.2 iso-4.3.2.
Here I have a table and I am creating one mutable array like
mainarray=[[NSMutableArray alloc]initWithObjects:#"Hi",#"Hello"nil];
and sending that value to.Table delegate method like
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
here value is coming but once I am sending dynamically value to the mainarray like
mainarray=[[NSMutableArray alloc]initWithObjects:[dataarray valueForKey:#"first_name"],nil]; or
[mainarray addobject:[dataarray valueForKey:#"first_name"]]
and sending that mainarray value to cell.textlabel.text then my program is terminating and sending this error message.

Please, help.
Here you are getting this terminating log because
dataArray is an NSArray you can't call [dataarray valueForKey:#"first_name"] this
because this unreconised for NSArray
rether than this you may use some thing like this
[[dataarray objectAtIndex:index] valueForKey:#"first_name"]
[__NSArrayI isEqualToString:]: is the issue. You are using the isEqualToString: for an array somewhere. Check that. Its a method of NSString
Initialization of array was wrong.
Following line
mainarray=[[NSMutableArray alloc]initWithObjects:#"Hi",#"Hello"nil];
should be corrected as
mainarray=[[NSMutableArray alloc]initWithObjects:#"Hi",#"Hello" , nil];
Please note the new comma between #"Hello" and nil

i'm kinda new to Objective-C so i have been learning with the Head First iPhone & iPad Development book. In this book, at the Chapter 4-5 you suppose to design an app for a bartender, that basically is a table view of a list of drinks with the details list (it suppose to have the ingredients and directions for the drink selected). The data comes from two property lists, one has a list of strings with the names of the drinks, and the other is a Dictionary that has the name, directions and ingredients of the drinks.
I have followed the tutorial and the app crashes, re-checked it and still crashes. I'm using an Xcode Version of 4.0.1 and MAC OS X 10.6.8.
Here is the exception, i hope that you guys can check out what happens at this simple application.

And here is exactly when the app crashes, at the objectForKey:#"name"
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
cell.textLabel.text = [[self.drinks objectAtIndex:indexPath.row] objectForKey:#"name"];
return cell;
}
the clue in the first line of the error is that you have initialized the contents of self.drinks at the index that corresponds to indexPath.row to be an NSString. when that objectAtIndex: is retrieved, it is then passed the message objectForKey: as though it is an NSArray.
look at the code where you've initialized self.drinks and make certain you've made it an appropriate array containing appropriate contents. in your case, it would be an array of NSDictionary* for objectForKey: to work).
Debug your code and check drinks is an array of NSDictonary.
I've been banging my head against the wall for the past 2 days with it - and I need help.
In my controller, I have this code:
- (void)viewDidLoad {
[super viewDidLoad];
self.navigationController.toolbar.barStyle = UIBarStyleBlack;
[self.navigationController setToolbarHidden:NO];
... // the rest of initialisation goes here
}
This controller presents details of one item selected from the list. Controller displaying a list of items does pushViewControllerAnimated on this controller to display details of the item selected by the user.
This works fine on the first execution, however when the user presses back button - and then selects another (or even the same) item from the list, line [self.navigationController setToolbarHidden:NO] causes SIGABRT with this stack trace:

I thought, maybe, I should setup self.toolbarItems first before making the toolbar visible - but then I get this same error when I do
self.toolbarItems = [NSArray ...]
I'm desperate now - any help is appreciated.
Edit: Now for some reason I'm getting EXC_BAD_ACCESS instead of SIGABRT - in the same place - and no stack trace is produced at all.
As the stack trace tells:
-[NSCFNumber view]: unrecognized selector sent to instance 0x69db0e0
You are accidentally overreleasing something that is leading to this message sent to some dangling pointer (reference to some junk).
Check if you are releasing your navigationController, ViewController or anything where your workflow begins.
When I search on TableView through TextDidChange which calls handleSearchTerm subroutine, it perfectly works. However, I removed TextDidChange and use SearchButtonClicked to update tableView (use same subroutine),it doesn't update TableView properly and crash when scroll(out of bound index in cellForRowAtIndex) even though datasource has been changed in subroutine. Any idea?

I think crash is caused by cellForRowAtIndexPath, can you please post code for following methods :
cellForRowAtIndexPath
SearchButtonClicked
yourSubroutine you are calling
also mention your array or collection from which you are loading your table.
Thanks,
as per your crash log it seems you are retuning wrong no of cells in you noOfcellsInsection method. You are getting array out of bounds error.When you are doing search make a flag true and according to that flag return no of rows for the table view using your filtered array's count.
I downloaded the OHGridView hoping that it was the answer to all my problems.
https://github.com/AliSoftware/OHGridView
I did all that it said to do (add the class files, add the code, and change a few other things).
I went to build it and it crashed. I realized the lines of code why it was crashing:
((OHGridView *)self.view).rowHeight = 100;
((OHGridView *)self.view).columnsCount = 2;
Error from Console:

I removed them and it loaded fine but I didn't see any content.
Please help,
thanks.
I did a clone of the repository just now and then did a build and run of his example project without making any changes to the code. It ran without any warnings or errors.
You'll need to check your code wherever you made changes.
update after your comment
Unrecognized Selector often means that you have a capitalization error or that your code isn't the kind of object that you think it is.
For example: I can get almost the same error that you get if I try to call the setRowHeight: directly against a OHGridView object instead of the view property of the object, like this
((OHGridView*)self).rowHeight = 100;
((OHGridView*)self).columnsCount = 2;
So, I would check your code to make sure that your object is an OHGridView and that you are setting the rowHeight property of the view of the OHGridView.
I am using CustomCell tableview, download data and binding it.When i tap multiple time am getting this error.

**Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[CALayer numberOfSectionsInTableView:]: unrecognized selector sent to instance 0x184250'**
Thanks
Thanks for the detail view of your problem but the only important part is this
-[NSCFString numberOfSectionsInTableView:]: unrecognized selector
It tells that you are calling the method numberOfSectionsInTableView: on a NSCFString
which is seem to be wrong
so check where is that method called in your code
And also the rest is not require in your case.
Edit:
did you release your custom cell in the delegate method tableview. if yes than use autorelease instead.
