I am trying to implement security in GCDAsyncSocket using the self signed certificate. After calling the startTLS, didReceiveTrust method is not getting called.
SecIdentityRef identityRef = nil;
NSArray *certs = [[NSArray alloc] initWithObjects:(__bridge id)identityRef, nil];
NSMutableDictionary *settings = [NSMutableDictionary dictionaryWithCapacity:3];
[settings setObject:[NSNumber numberWithInteger:0] forKey:GCDAsyncSocketSSLProtocolVersionMax];
[settings setObject:[NSNumber numberWithBool:YES] forKey:GCDAsyncSocketManuallyEvaluateTrust];
[settings setObject:certs forKey:GCDAsyncSocketSSLCertificates];
You don't show where settings is being used.
In your call to startTLS, you must set GCDAsyncSocketManuallyEvaluateTrust to #YES:
[self.socket startTLS:#{GCDAsyncSocketManuallyEvaluateTrust: #YES}];
Relevant documentation: http://cocoadocs.org/docsets/CocoaAsyncSocket/7.4.1/Classes/GCDAsyncSocket.html#//api/name/startTLS:

Okay so I ask the Core Data for a record (userKey), in that record is a PublicKey which I am extracting, however, publicKey ends up being 90% right but has a few extra characters at the beginning and is encapsulated in brackets.
I think my problem is I am getting a pointer rather than the data from the userMatches. Any guidance would be appreciated.
AppDelegate *appdelagate = [[UIApplication sharedApplication]delegate];
context = [appdelagate managedObjectContext];
NSEntityDescription *entitydesc = [NSEntityDescription entityForName:#"KeyData" inManagedObjectContext:context];
NSFetchRequest *request = [[NSFetchRequest alloc]init];
predicate = [NSPredicate predicateWithFormat:#"userKeyCD = %#", userKey];
[request setEntity:entitydesc];
[request setPredicate:predicate];
userMatches = [context executeFetchRequest:request error:&error];
NSString *publicKey = [userMatches valueForKey:#"publicKeyCD"];
Okay so I changed the last line to this and it worked fine;
NSString *publicKey = [[userMatches objectAtIndex:0] valueForKey:#"publicKeyCD"];
I did not show how it was defined but userMatches is an NSArray (sorry). It is used in a similar way further up the code;
NSArray *userMatches = [context executeFetchRequest:request error:&error];
Now I think about it is an array the right type?
I have the following code in my .m file:
- (IBAction)LoginButton:(id)sender {
// create string contains url address for php file, the file name is phpFile.php, it receives parameter :name
NSString *strURL = [NSString stringWithFormat:#"http://www.myURL.com/verify.php?Email=%#",Email.text];
// to execute php code
NSData *dataURL = [NSData dataWithContentsOfURL:[NSURL URLWithString:strURL]];
// to receive the returend value
NSString *strResult = [[[NSString alloc] initWithData:dataURL encoding:NSUTF8StringEncoding]autorelease];
NSLog(#"%#", strResult);
UIAlertView *alert = [[UIAlertView alloc]
initWithTitle:#"Result:"
message:strResult
delegate:nil
cancelButtonTitle:#"Okay"
otherButtonTitles:nil];
[alert show];
}
And I am getting that autorelease is unavailable in automatic reference counting mode.
It seems to be an issue with the following line:
NSString *strResult = [[[NSString alloc] initWithData:dataURL encoding:NSUTF8StringEncoding]autorelease];
How can I solve this?
Just delete the autorelease call; if you are using ARC (Automatic Reference Counting) you don't need to worry about memory management.
I have a Cocoa Webview subclass, and I need to make all text copied from it be plaintext only. I have tried overriding -copy and -pasteboardTypesForSelection, but no luck, and debugging code seems to indicate that those methods are never called. I've also tried setting -webkit-user-modify to read-write-plaintext-only in the css (this would also work in this situation) but that seemed to have no effect.
Any ideas?
Okay this seems to work (with the subclass instance as its own editing delegate):
- (BOOL)webView:(WebView *)webView doCommandBySelector:(SEL)command
{
if (command == #selector(copy:)) {
NSString *markup = [[self selectedDOMRange] markupString];
NSData *data = [markup dataUsingEncoding: NSUTF8StringEncoding];
NSNumber *n = [NSNumber numberWithUnsignedInteger: NSUTF8StringEncoding];
NSDictionary *options = [NSDictionary dictionaryWithObject:n forKey: NSCharacterEncodingDocumentOption];
NSAttributedString *as = [[NSAttributedString alloc] initWithHTML:data options:options documentAttributes: NULL];
NSString *selectedString = [as string];
[as autorelease];
NSPasteboard *pasteboard = [NSPasteboard generalPasteboard];
[pasteboard clearContents];
NSArray *objectsToCopy = [NSArray arrayWithObject: selectedString];
[pasteboard writeObjects:objectsToCopy];
return YES;
}
return NO;
}
Not sure if this is the best way.
Hi I set up my own coredata app, or I tried...
First I created the xdatamodel and generated the Modelclasses, after this I implemented all the function of core-data in AppDelegate which I found in a generated project. Finally I copied the fetchedResultsController in my TableViewController.
fetchedResultsController
- (NSFetchedResultsController *)fetchedResultsController {
if (fetchedResultsController_ != nil) {
return fetchedResultsController_;
}
NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init];
NSEntityDescription *entity = [NSEntityDescription entityForName:#"ParameterGroup" inManagedObjectContext:self.managedObjectContext];
[fetchRequest setEntity:entity];
[fetchRequest setFetchBatchSize:20];
NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:#"name" ascending:NO];
NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil];
[fetchRequest setSortDescriptors:sortDescriptors];
NSFetchedResultsController *aFetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest managedObjectContext:self.managedObjectContext sectionNameKeyPath:nil cacheName:#"Root"];
aFetchedResultsController.delegate = self;
self.fetchedResultsController = aFetchedResultsController;
[aFetchedResultsController release];
[fetchRequest release];
[sortDescriptor release];
[sortDescriptors release];
NSError *error = nil;
if (![fetchedResultsController_ performFetch:&error]) {
NSLog(#"Unresolved error %#, %#", error, [error userInfo]);
abort();
}
return fetchedResultsController_;
}
First I checked if the managedObjectsController is != nil, it has a address
Then I copied the EntityName from my xdatamodel in entityForName,
but NSEntityDescricption entity is nil.
And if I just create a new object the exception says, that the entity doesn't exist
Do I have to connect the xdatamodel to my project?
Hope you can help me
Thanks a lot!!!
The most common cause of this problem is simply misspelling the entity name wrong in the code such that it doesn't match the entity name in the data model.
Copy and paste the entity name from the model to the code and see if that fixes the problem.
The simplest way to solve this, given that you haven't done a lot coding on non-core-data parts, is probably to create a new project where you check the box for "Use Core Data". If you're going to use a Navigation Bar, choose this as your template. If I recall correctly, this will generate a table view with all functions needed. You'll have to modify the datamodel (generated).
Remark that you'll have to delete the app from the Simulator if it is installed and you change the datamodel (otherwise the generated data will not be consistent with the datamodel and the app will crash)
I was make communication for client-server application and have strange problem.
here is a code where i pickup objects.
- (byref NSArray*)objectsOfName:(bycopy NSString*)name
withPredicate:(bycopy NSPredicate*)predicate;
{
NSManagedObjectContext *context = [self managedObjectContext];
NSError *error = nil;
NSFetchRequest *request = [[NSFetchRequest alloc] init];
[request setEntity:[NSEntityDescription entityForName:name
inManagedObjectContext:context]];
[request setPredicate:predicate];
NSArray *results = [context executeFetchRequest:request error:&error];
[request release], request = nil;
if (error) {
NSLog(#"%#:%# Error on fetch %#", [self class], NSStringFromSelector(_cmd), error);
return nil;
}
//NSLog(#"%#:%# Result of fetch is %#", [self class], NSStringFromSelector(_cmd), results);
return results;
}
Here is pickup:
NSArray *destinations;
#ifdef SNOW_CLIENT
destinations = [server objectsOfName:#"DestinationsListWeBuy" withPredicate:predicate];
If i do
NSLog(#"Destination:%#\n",destinations);
i seen all objects in log.
If i try to do
NSLog(#"all:%#\n%#\n%#\n",[[destinations objectAtIndex:0] valueForKey:#"rate"],[[destinations objectAtIndex:0] valueForKey:#"lastUsedACD"],[[destinations objectAtIndex:0] valueForKey:#"lastUsedCallAttempts"]);
i seen attributes also.
But, if i try to do loop around objects:
for (NSManagedObject *dest in destinations)
{
NSLog(#"all:%#\n%#\n%#\n",[dest valueForKey:#"rate"],[dest valueForKey:#"lastUsedACD"],[dest valueForKey:#"lastUsedCallAttempts"]);
i have EXC_BAD_ACCESS in this part of code:
for (NSManagedObject *dest in destinations)
all debug technic, which i know, don't give me possibility to understand, what happened. (NSZombieEnabled = YES)
if i do loop at another manner:
for (NSUInteger count = 0;count < [destinations count]; count++)
NSLog(#"all:%#\n%#\n%#\n",[[destinations objectAtIndex:count] valueForKey:#"rate"],[[destinations objectAtIndex:count] valueForKey:#"lastUsedACD"],[[destinations objectAtIndex:count] valueForKey:#"lastUsedCallAttempts"]);
i seen all keys without exception. All nsmanagedobject's is subclassed.
If i need implement encodeWithCored method for all subclasses, examples is appreciated.
*UPDATE for Marcus *
This is how i receive objects from server side:
- (byref NSArray*)allObjects
{
NSPersistentStoreCoordinator *coordinator = [self persistentStoreCoordinator];
if (!coordinator) {
NSMutableDictionary *dict = [NSMutableDictionary dictionary];
[dict setValue:#"Failed to initialize the store" forKey:NSLocalizedDescriptionKey];
[dict setValue:#"There was an error building up the data file." forKey:NSLocalizedFailureReasonErrorKey];
NSError *error = [NSError errorWithDomain:#"YOUR_ERROR_DOMAIN" code:9999 userInfo:dict];
[[NSApplication sharedApplication] presentError:error];
return nil;
}
NSManagedObjectContext *moc = [[NSManagedObjectContext alloc] init];
[moc setPersistentStoreCoordinator:coordinator];
[moc setUndoManager:nil];
NSNotificationCenter *nc = [NSNotificationCenter defaultCenter];
[nc addObserver:self
selector:#selector(mergeChangesForClient:)
name:NSManagedObjectContextDidSaveNotification
object:thirdMOC];
NSFetchRequest *request = [[NSFetchRequest alloc] init];
NSEntityDescription *entity = [NSEntityDescription entityForName:#"Carrier"
inManagedObjectContext:moc];
[request setEntity:entity];
[request setIncludesSubentities:YES];
NSError *error = nil;
NSArray *objects = [moc executeFetchRequest:request error:&error];
[request release], request = nil;
for (NSManagedObject *carrier in objects) {
NSSet *destinations = [carrier valueForKeyPath:#"destinationsListForSale"];
for (NSManagedObject *destination in destinations) [destination addObserver:self forKeyPath:#"rate" options:NSKeyValueObservingOptionNew context:nil];
}
if (error) {
NSLog(#"%#:%# error: %#", [self class], NSStringFromSelector(_cmd), error);
return nil;
}
return objects;
}
This is what i do with them on client side:
NSArray *allObjects = [server allObjects];
[carrierArrayController setContent:allObjects];
There is no serialization in this case. Any other ways (like send copy of server moc to client side doesn't work, it just generate exceptions on main.c).
p.s. many thanks to Marcus for his Core Data book.
unrecognized selector sent to class 0x1000a2ed8 2011-03-17 02:15:18.566 snowClient[19380:903] +[AppDelegate encodeWithCoder:]: unrecognized selector sent to class 0x1000a2ed8
That is not a core data problem. That is an error in your code where you are trying to call a method on an object that does not respond to that method. You need to track that down as it appears that you are trying to serialize your AppDelegate.
Update
What kind of class is 0x1000a2ed8? Break on the exception and print out the object to see what it is. Again, this is not a core data error directly, it is sending a messages to an object that does not respond to that message. It is possible that Core Data no longer allows you to send Managed objects across as distributed objects. It is possible that this is simply an issue with an over-released object. No way to know without further investigation.
Step one: Find out what object 0x1000a2ed8 is and see if the object changes from one run to the next.
