Help please to solve the problem - I do not understand why there is an error - unrecognized selector send to instance.
The error occurs when this code in AppDelegate is executed:
TMMonth *m = [NSEntityDescription insertNewObjectForEntityForName:#"TMMonth" inManagedObjectContext:self.managedObjectContext];
m.paymentMonth=#"month";
[self.managedObjectContext save:nil];
reason: Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[TMMonth name]: unrecognized selector sent to instance 0x7f993bdbbb00'
But in my code there is no selector 'name' in TMMonth class.

I am getting the following exception, which is terminating the app.
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSArrayM objectForKey:]: unrecognized selector sent to instance 0x7abe4f90'
Following is the code:
- (NSMutableData*)dataForConnection:(URLConnection*)connection {
NSMutableData *data = [receivedData objectForKey:connection.tagKey]; // Exception Here
return data;
}
Could anyone please suggest how to fix it? Thank you in advance!
Problem is due to not allocating receivedData properly, since you have declared it as instance variable, so you should make it using the property declaration like this:
#property(nonatomic, strong) NSMutableDictionary *receivedData;
This will ensure that receivedData does not get released and reference this using self.receivedData in your code.
Maybe this is helpful
[__NSArrayM objectForKey:]
NSArray have not method called objectForKey:
Your object receivedData is NSArray class , change to NSDictionary.
I'm working on an app and it's my first time using Core Data and everything was going smooth until I hit a rock.
Here is my stack trace

and here is the code that caused the problem:
- (void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
//Fetch data from persistence
NSManagedObjectContext *managedObjectContext = [self managedObjectContext];
NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] initWithEntityName:#"Entity1"];
NSFetchRequest *fetchRequest2 = [[NSFetchRequest alloc] initWithEntityName:#"Entity2"];
self.arr1 = [[managedObjectContext executeFetchRequest:fetchRequest error:nil]mutableCopy];
self.arr2 = [[managedObjectContext executeFetchRequest:fetchRequest2 error:nil]mutableCopy];
[self.tableView reloadData];
}
I really don't get what's wrong.
Thanks in advance
Usually, this error is about the entity name you're using is not kind of NSString, so the code believes that you are using some type else (not NSString).
But it could be also, that is the model associated with the context’s persistent store coordinator does not contain an entity named Entity1.
I am using BlackRaccoon to download a file from FTP server. Following is the code:
- (IBAction)download:(id)sender {
downloadData = [NSMutableData dataWithCapacity: 1];
downloadFile = [[BRRequestDownload alloc] initWithDelegate: self];
downloadFile.path = #"psnewsletter.pdf";
downloadFile.hostname = #"server";
downloadFile.username = #"user";
downloadFile.password = #"pswd";
[downloadFile start];
}
Its gives following error
2014-02-20 11:48:43.526 BlackHillPrimarySchool[2036:a0b] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[MainViewController requestFailed:]: unrecognized selector sent to instance 0xcd609f0'
Any help will be appreciated.
requestFailed: is one of the BRRequest delegate method that you must implement in your view controller.
- (void)requestFailed:(BRRequest *)request {
BRRequestError *reqError = request.error;
// check the error, handle as needed.
}
I'm not sure how your code even compiled. This is a required method of the protocol.
core data getting on my nerves. i' m deleting old data and want to insert new data received from server.
now the deleting part gives a "sigabort":
-[NSManagedObjectContext delete:]: unrecognized selector sent to instance 0x522f550
2013-09-27 14:05:56.592 * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NSManagedObjectContext delete:]: unrecognized selector sent to instance 0x522f550'

deleting happens in background and nsmanagedobjectcontext is a privet concurrency type
i printed the pointer for context and object context
po context NSManagedObjectContext: 0x522f550
and
po tmpCon.managedObjectContext NSManagedObjectContext: 0x522f550>
and the code for deleting is:
NSError *errorAllCons = nil;
NSFetchRequest *allevents = [[NSFetchRequest alloc] init];
[allevents setEntity:[NSEntityDescription entityForName:#"TEventContact" inManagedObjectContext:context]];
NSArray *allCons = [context executeFetchRequest:allevents error:&errorAllCons];
for (TEventContact *tmpCon in allCons)
{
[context delete:tmpCon];
}
and it crashes on [context delete:tmpCon];
can someone let me know what am i doing wrong?
Use
[context deleteObject:tmpCon];
It will solve the problem
do it like this for deleting an object permanently
for (TEventContact *tmpCon in allCons)
{
[context deleteObject:tmpCon] /// for deleting object in context
}
[context save]; /// to reflect changes in database you need to save that context
without saving the context it doesn't reflect on data base and that may cause DIRTY_READ for another context
i've a piece of code that should get the current location and than put lat and long in a string.
when a new location is found i put it in a NSString
currentLatit = [NSString stringWithFormat:#"%f",newLocation.coordinate.latitude];
currentLongit = [NSString stringWithFormat:#"%f",newLocation.coordinate.longitude];
Than when i press a button i do:
NSLog(currentLatit);
[[UIApplication sharedApplication] openURL:[[NSURL alloc] initWithString: [NSString stringWithFormat:#"http://maps.google.com/maps?saddr=%#,%#&daddr=%#,%#",currentLatit,currentLongit,detailLatitudine,detailLongitudine]]];
but when i execute this, i get this error:
-[__NSCFArray length]: unrecognized selector sent to instance 0x1e1830

terminate called throwing an exception(gdb)
The error occur on the NSLog execution
realy cannot understand what's wrong whit this simple code...
thanks for any help
-UPDATE-
changed the NSLog as follow:
NSLog(#"%#",currentLatit);
Now the app crash with BAD_ACCESS_EXCEPTION on the NSLog
No, it seems the app crashed at some point other than NSLog. Please clean and build. Or Enable NSZombie and get the exact error location.
Update:
Just do like as following and try.
if( currentLatit )
[currentLatit release];
if( currentLongit )
[currentLongit release];
currentLatit = [[NSString stringWithFormat:#"%f",newLocation.coordinate.latitude] retain];
currentLongit = [[NSString stringWithFormat:#"%f",newLocation.coordinate.longitude] retain];
