-[NSPathStore2 objectForKey:]: unrecognized selector sent to instance 0x6a3fc60' - iphone

Question

I was preparing for a customCellView in a tableView. According to me, everything was perfect in .xib and methods. I am getting an exception in configuring the cell.
int listIndex = [indexPath indexAtPosition:[indexPath length] - 1];
NSLog(#"outside");
cell.lblName.text = (NSString *) [[directoryContent objectAtIndex:listIndex] objectForKey:#"filesName"];
cell.lblSize.text = (NSString *) [[directoryContent objectAtIndex:listIndex] objectForKey:#"filesSize"];
cell.lblType.text = (NSString *) [[directoryContent objectAtIndex:listIndex] objectForKey:#"filesType"];
return cell;
The compiler works till the NSLog(#"outside");. But it does not proceeds to the next line. I am terminated by the error

Please help me to proceed.. Thank you in advance..

Answer 1

Wherever you created directoryContent, you stored the wrong object in it.
NSPathStore2 is an object that will be created if you use something like stringByAppendingPathComponent: on a NSString.
I guess you just stored the filename in the array but wanted to store a NSDictionary created from NSFileManagers attributesOfItemAtPath:error:
Check that part were you add objects to directoryContent again.

Answer 2

This is my code. Have a look at this. Let me know what i am lagging.
- (void)listFiles {
NSFileManager *fm =[NSFileManager defaultManager];
NSError *error = nil;
NSString *parentDirectory = #"/Users/akilan/Documents";
NSArray *paths = [fm contentsOfDirectoryAtPath:parentDirectory error:&error];
if (error) {
NSLog(#"%#", [error localizedDescription]);
error = nil;
}
NSMutableArray *array = [[NSMutableArray alloc] init];
self.directoryContent = array;
[array release];
for (NSString *path in paths){
filesName = [[path lastPathComponent] stringByDeletingPathExtension];
filesPath = [parentDirectory stringByAppendingPathComponent:path];
filesDirectory = [NSMutableDictionary dictionaryWithDictionary:[[NSFileManager defaultManager] attributesOfItemAtPath:filesPath error:nil]];
filesSize = [filesDirectory objectForKey:NSFileSize];
filesType = [path pathExtension];
createdDate = [filesDirectory objectForKey:NSFileCreationDate];
modifiedDate = [filesDirectory objectForKey:NSFileModificationDate];
filesDirectory = [NSDictionary dictionaryWithObjectsAndKeys:filesPath,#"filesPath",
filesName,#"filesName",filesSize, #"filesSize", filesType, #"filesType",
createdDate,#"createdDate", modifiedDate,#"modifiedDate", nil];
NSLog(#"%#", filesDirectory);
}
}
Thanks..

You have not retained directoryContent.
Can you show the code where directoryContent is created?
You can tell this because your error message says NSPathStore2 when it should be trying to call objectforKey on NSDictionary - this means that the memory where your dictionary was is not being used by something else :)
