and it is called this:
Exception Type: NSRangeException
Reason: -[__NSCFArray objectAtIndex:]: index (14) beyond bounds (14)
It only happened once so I am not sure how to reproduce it. But it happened in this code:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSDictionary *info = [topics_array objectAtIndex:indexPath.row];
NSString *section_name = [info objectForKey:#"section_name"];
NSString *solution_section_id = [info objectForKey:#"solution_section_id"];
// PUT THESE ITEMS INTO THE SESSION
NSUserDefaults *standardUserDefaults = [NSUserDefaults standardUserDefaults];
[standardUserDefaults setObject:section_name forKey:#"section_name"];
[standardUserDefaults setObject:solution_section_id forKey:#"solution_section_id"];
[standardUserDefaults synchronize];
[self performSegueWithIdentifier:#"BusinessToTopic" sender:self];
}
Would anyone know how to prevent this from happening in the future and why it is happening?
EDIT:
This is the code for tableView numberOfRowsInSection
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [tableLabels count];
}
Thanks!

I have a custom class oject that I want to save using NSUserDefaults, this is how I saving it:
Shift.m
-(void)encodeWithCoder:(NSCoder*)encoder
{
[encoder encodeObject:self.date forKey:#"date"];
[encoder encodeObject:self.startTime forKey:#"startTime"];
[encoder encodeObject:self.endTime forKey:#"endTime"];
}
- (id)initWithCoder:(NSCoder *)decoder {
if(self = [super init]) {
self.date = [decoder decodeObjectForKey:#"date"];
self.startTime = [decoder decodeObjectForKey:#"startTime"];
self.endTime = [decoder decodeObjectForKey:#"endTime"];
}
return self;
}
MyTableViewController.m:
-(void)saveCustomObject:(id)object forKey:(NSString*)key
{
NSData *encodedObject = [NSKeyedArchiver archivedDataWithRootObject:object];
[[NSUserDefaults standardUserDefaults] setObject:encodedObject forKey:key];
}
-(NSArray*)getCustomObjectForKey:(NSString*)key
{
NSData *encodedObject = [[NSUserDefaults standardUserDefaults] objectForKey:key];
NSArray *shifts=[NSArray arrayWithObjects:[NSKeyedUnarchiver unarchiveObjectWithData:encodedObject], nil];
return shifts;
}
It seems it works fine when debugging, but when I try to access one of the object properties, for example on tableView: cellForRowAtIndexPath: like that:
Shift *currentShift=[self.shifts objectForIndex:indexPath.row];
NSLog(#"%#",currentShift.startTime.description);
It crashes with that crash message:

Any one knows why?
Thank you!
It seems like you want Shift *currentShift=[self.shifts objectForIndex:indexPath.row] to give you 1 Shift object, but what it really does is returning a NSArray. You basically call a startTime method in NSArray, and since it doesn't exist, your program fails.
It seems like NSLog(#"%#",currentShift.startTime.description) is the line doing that. Confirm by commenting out the NSLog. It shouldn't give you a crash.
If this hypothesis is fine, check if [currentShift isKindOfClass:[NSArray class]] is true.
If it is, a bug you have in this line:
NSArray *shifts=[NSArray arrayWithObjects:[NSKeyedUnarchiver unarchiveObjectWithData:encodedObject], nil];
You also don't really show how your - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section looks like. You must return proper number of entries there.
You're making self.shifts be an NSArray, but you use objectForKey, which is available for dictionaries. It's not available for arrays. I think you wanted objectAtIndex instead.
Im new to objective C and I was wondering if someone can help me figure out why my app keeps crashing. I believe it has something to do with my Array but I'm not sure how to fix it.. Can someone help please???..
Here's the Log output when it crashes:

Quite clear, your array doesn't have as many elements as you think it has. Put a break point at the places where your array is populated and double check it's as expected.

The problem has nothing to do with the code that you provided. The error messages says that the message count was sent to the class NSConcreteData, which is essentially the same as NSData, and such a class method does not exist.
I suggest that you set an exception breakpoint (in Xcode select left the breakpoint navigator, click + left bottom, and select add exception breakpoint).
When you execute the app, it will stop at the faulty instruction.
EDIT (due to the stack trace you provided now):
The stack trace indeed says that your method applyFilters:fromFilter: is responsible for the crash. The only place where the message count is sent in this method, is the statement [[filters allKeys] count]. It looks then that count is sent to an NSConcreteData object, and not to an NSArray object as you might have expected. One reason could be that the argument filters, that should be a NSDictionary, is an object of a different type.
So when the app stops at the exception breakpoint, please check the class of the instance filters.
I have an NSMutableArray that I have build up that consists or holds a NSMutableDictionary.
NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];
self.userNameArray = [NSMutableArray arrayWithArray:[userDefaults arrayForKey:#"userNameTextArray"]];
NSMutableArray *arrayToAdd = [[NSMutableArray alloc] init];
for (id object in self.userNameArray) {
[arrayToAdd addObject:#"Negative"];
}
self.namesDictionary = [#{ #"userNameText" : self.categoriesMutableNameArray, #"selectedCellState" : arrayToAdd}mutableCopy];
self.namesFinalArr = [[NSMutableArray alloc] init];
self.namesDictMutableDict = [NSMutableDictionary dictionaryWithDictionary:self.namesDictionary];
[self.namesFinalArr addObject:self.namesDictMutableDict];
The result in my NSlog of the above code is like this:
(
{
selectedCellState = (
Negative,
Negative,
Negative,
Negative,
Negative,
Negative,
Negative,
Negative,
Negative,
Negative,
Negative,
Negative,
Negative,
Negative
);
userNameText = (
"userText - Text",
"userText1 - Text1",
"userText2 - Text2",
"userText3 - Text3",
"userText4 - Text4",
"userText5 - Text5",
"userText6 - Text6",
"userText7 - Text7",
"userText8 - Text8",
"userText9 - Text9",
"userText10 - Text10",
"userText11 - Text11",
"userText12 - Text12",
"userText13 - Text13"
);
}
)
I am using a UITableview and I populate the UITableview with self.namesFinalArr . in the CellForRow method like this and it works:
labelForTableCell.text = [[[self.namesFinalArr objectAtIndex:0] objectForKey:#"userNameText"]objectAtIndex:indexPath.row];
This populates my UITableview with the data under userNameText in self.namesFinalArr
I am trying to enable or disable an image on a cell when it is selected and I use the didDeselectRowAtIndexPath and didselectRowAtIndexPath methods to show and hide a UImageview
This works but I am trying to update selectedCellState in self.namesFinalArr at the index row or row that was pressed but I get the following error.
In the didselectRowAtIndexPath method I do something like this:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
self.selectedRows = [self.tableView indexPathsForSelectedRows];
[[[[self.namesFinalArr objectAtIndex:0] objectForKey:#"selectedCellState"]objectAtIndex:indexPath.row] setValue:#"Positive" forKey:#"selectedCellState"];
}
When trying to change the array value and index row I get a error:
Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<__NSCFConstantString 0x23fef0> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key selectedCellState.'

In this case,there is one array which contains two dictionary each contains array and you are suppose to change the values in array and you should used this method to change the value
[[[self.namesFinalArr objectAtIndex:0] objectForKey:#"selectedCellState"] replaceObjectAtIndex:indexPath.row withObject:#"Positive"];
I have a NSDictionary that I add to a mutable array but when I try add the array to populate a uitableview I get an error.
NSMutableArray *array = [[NSMutableArray alloc] init];
for (id element in self.categoriesMutableNameArray) {
[array addObject:#"No"];
}
self.categoryDict = #{ #"title" : self.categoriesMutableNameArray, #"selected" : array};
self.categoryArr = [[NSMutableArray alloc] init];
self.categoryMutableDict = [NSMutableDictionary dictionaryWithDictionary:self.categoryDict];
[self.categoryArr addObject:self.categoryDict];
and the following categoryArr is printed like this:
2014-02-27 15:09:07.397 App[7982:70b] (
{
selected = (
No,
No,

Inspiration,
"Decoration / Architecture",
"Great Places",
"Art / Design",
"Music / Movie / Books",

);
}
)
The trouble I am having is in the uitableview cellforrowatindexpath method I try and add the title key for the categoryArr to populate the uitableview and I get the following error on this line:
UILabel *categoryLabel = (UILabel *)[cell viewWithTag:111];

Thanks
The return of [[self.categoryArr objectAtIndex:indexPath.row] objectForKey:#"title"]; is a array of NSString, categoryLabel.text = [NSString stringWithFormat:#"%#", /*the return array*/]; this is the problem.
Maybe what you want is:
NSArray *categoryDetailArr = [[self.categoryArr objectAtIndex:indexPath.section] objectForKey:#"title"];
categoryLabel.text = [[categoryDetailArr objectAtIndex:indexPath.row];
Write this code
categoryLabel.text = [[[self.categoryArr objectAtIndex:0] objectForKey:#"title"]objectAtIndex:indexPath.row];
instead OF
categoryLabel.text = [NSString stringWithFormat:#"%#",[[self.categoryArr objectAtIndex:indexPath.row] objectForKey:#"title"];
And plz check that in UITableView dataSource methods i.e
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [categoryLabel objectAtIndex:0]valueForKey:#"selected"].count;
}
OR
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [categoryLabel objectAtIndex:0]valueForKey:#"title"].count;
}
