Is there any way to save chat history to xmpp server permanently.
i.e if i uninstall the application and install it again i am able to restore all the chat from the server?
I am using below code :-
XMPPMessageArchivingCoreDataStorage *_xmppMsgStorage = [XMPPMessageArchivingCoreDataStorage sharedInstance];
NSManagedObjectContext *moc = [_xmppMsgStorage mainThreadManagedObjectContext];
NSEntityDescription *entityDescription = [NSEntityDescription entityForName:#"XMPPMessageArchiving_Message_CoreDataObject"
inManagedObjectContext:moc];
NSFetchRequest *request = [[NSFetchRequest alloc]init];
[request setEntity:entityDescription];
// [request setFetchLimit:20];
NSError *error;
NSString *predicateFrmt = #"bareJidStr == %#";
NSPredicate *predicate = [NSPredicate predicateWithFormat:predicateFrmt, userJid];
request.predicate = predicate;
NSArray *messages = [moc executeFetchRequest:request error:&error];
But in this case if i uninstall the application the messages get deleted.

I have created a an entity called Statutory with four columns namely name,complianceName,statMappingName,country
i want a get all complianceName names that matches a specific statMappingName. Following is my code
NSString *nameToGet = self.statNameArray[indexPath.row] ;
NSPredicate *predicate = [NSPredicate predicateWithFormat:#"complianceName = %#", nameToGet];
[fetch setPredicate:predicate];
NSLog(#"n %#",predicate);
NSError *error = nil;
NSArray *results = [[self managedObjectContext] executeFetchRequest:fetch error:&error];
if(results) {
NSLog(#"Entities with that name: %#", results);
} else {
NSLog(#"Error: %#", error);
}
But it is not providing the compliance name specific to that statMappingName. How can I be able to get all complianceName that has a specific statMappingName?
Try this:-
NSString *firstName = statMappingName;
[fetchRequest setPredicate:[NSPredicate predicateWithFormat:#"firstName == %#", firstName]];
If you want to fetch specific column from core data
You can use the below method:-
NSEntityDescription *entity = [NSEntityDescription entityForName:entityname inManagedObjectContext:self.managedObjectContext];
NSFetchRequest *request = [[NSFetchRequest alloc] init];
[request setReturnsObjectsAsFaults:NO];
[request setEntity:entity];
[request setFetchLimit:1];
[request setPredicate:[NSPredicate predicateWithFormat:#"(complianceName LIKE %#)",nametoGet]];
NSError *error = nil;
NSMutableArray *tempDataArr = [[self.managedObjectContext executeFetchRequest:request error:&error] mutableCopy];
Note:-
*entityname: Your entity name
*self.managedObjectContext : Your managedobjectcontext
To Get All compliance Name use the below method
NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] initWithEntityName:entityName];
[fetchRequest setReturnsObjectsAsFaults:NO];
NSMutableArray *tempDataArr =[NSMutableArray new];
[fetchRequest setPredicate:[NSPredicate predicateWithFormat:#"(ANY complianceName LIKE %#)",nametoGet]];
tempDataArr = [[self.managedObjectContext executeFetchRequest:fetchRequest error:nil] mutableCopy];
try these code for contains statMappingName
NSPredicate *predicate = [NSPredicate predicateWithFormat:#"complianceName contains[c] %#", statMappingName];
I am unable to get the history from open fire. I am using XMPP Framework
How to get chat history from open fire archive and print the history data in nslog?
You need to enable the option in openfire to get chat history.
Login on openfire, Go to group chat, then go to group chat settings, then go to history settings and then select show entire chat history option.
On Join xmpp group you have to write below code for store message in xmpp core database.
storage = [XMPPMessageArchivingCoreDataStorage sharedInstance];
moc = [storage mainThreadManagedObjectContext];
XMPPMessageArchiving *xmppMessageArchivingModule = [[XMPPMessageArchiving alloc] initWithMessageArchivingStorage:storage];
[xmppMessageArchivingModule setClientSideMessageArchivingOnly:YES];
[xmppMessageArchivingModule activate:xmppStream];
[xmppMessageArchivingModule addDelegate:self delegateQueue:dispatch_get_main_queue()];
after this when you enter in particular group you have to get history from xmpp core database using below code:-
XMPPMessageArchivingCoreDataStorage *_xmppMsgStorage = [XMPPMessageArchivingCoreDataStorage sharedInstance];
NSManagedObjectContext *moc = [_xmppMsgStorage mainThreadManagedObjectContext];
NSEntityDescription *entityDescription = [NSEntityDescription entityForName:#"XMPPMessageArchiving_Message_CoreDataObject" inManagedObjectContext:moc];
NSFetchRequest *request = [[NSFetchRequest alloc]init];
[request setEntity:entityDescription];
NSError *error;
NSString *predicateFrmt = #"bareJidStr == %#";
NSPredicate *predicate = [NSPredicate predicateWithFormat:predicateFrmt, [NSString stringWithFormat:#"%#%#",GroupName,GROUP_CHAT_DOMAIN]];
request.predicate = predicate;
NSArray *messages = [moc executeFetchRequest:request error:&error];
I am new to xmpp , i need to store and show the chat history of users . i am getting the full history while using the below code.I only need the chat history of the selected user.
NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init];
XMPPMessageArchivingCoreDataStorage *xmppMessageArchivingCoreDataStorage=[XMPPMessageArchivingCoreDataStorage sharedInstance];
NSManagedObjectContext *context = [xmppMessageArchivingCoreDataStorage mainThreadManagedObjectContext];
NSEntityDescription *messageEntity = [NSEntityDescription entityForName:#"XMPPMessageArchiving_Message_CoreDataObject" inManagedObjectContext:context];
fetchRequest.entity = messageEntity;
NSSortDescriptor *sortDescriptor = [NSSortDescriptor sortDescriptorWithKey:#"timestamp" ascending:YES];
fetchRequest.sortDescriptors = [NSArray arrayWithObject:sortDescriptor];
NSError *error = nil;
NSArray *results = [context executeFetchRequest:fetchRequest error:&error];
[self print:[[NSMutableArray alloc]initWithArray:results]];
How can i get the chat history of a particular user,. i have searched a lot but couldnt got a success
Try this
- (void)loadChatHistoryWithUserName:(NSString *)userName
{
NSString *userJid = [NSString stringWithFormat:#"%##%#",userName,self.hostName];
NSManagedObjectContext *moc = [_xmppMsgStorage mainThreadManagedObjectContext];
NSEntityDescription *entityDescription = [NSEntityDescription entityForName:#"XMPPMessageArchiving_Message_CoreDataObject"
inManagedObjectContext:moc];
NSFetchRequest *request = [[NSFetchRequest alloc]init];
[request setEntity:entityDescription];
NSError *error;
NSString *predicateFrmt = #"bareJidStr == %#";
NSPredicate *predicate = [NSPredicate predicateWithFormat:predicateFrmt, userJid];
request.predicate = predicate;
NSArray *messages = [moc executeFetchRequest:request error:&error];
}
I save to core data and load all messages with code below, but how can I load only messages for 2 users, for self user and for destination user, I want base it on user JID.
NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init];
NSManagedObjectContext *context = [[self appDelegate].xmppMessageArchivingCoreDataStorage mainThreadManagedObjectContext];
NSEntityDescription *messageEntity = [NSEntityDescription entityForName:#"XMPPMessageArchiving_Message_CoreDataObject" inManagedObjectContext:context];
fetchRequest.entity = messageEntity;
NSSortDescriptor *sortDescriptor = [NSSortDescriptor sortDescriptorWithKey:#"timestamp" ascending:YES];
fetchRequest.sortDescriptors = [NSArray arrayWithObject:sortDescriptor];
NSError *error = nil;
NSArray *results = [context executeFetchRequest:fetchRequest error:&error];
//Now you get the NSArray with element type of "XMPPMessageArchiving_Message_CoreDataObject"
assuming your message objects have a from relationshit to a User entity.
As simple as adding (before executing the request):
fetchRequest.predicate = [NSPredicate predicateWithFormat:#"from = %# OR from = %#",selfUser,otherUser];
Where selfUser and otherUser are User core data managed objects or managed object IDs of users.
if you use a field identifier (highly not recomended):
fetchRequest.predicate = [NSPredicate predicateWithFormat:#"bareJID.bare = %# OR bareJID.bare = %#",selfUser.jid,otherUser.jid];

I have used following method and it worked correctly :)
-(void)checkForPastMessageAndDisplayIt
{
NSString *strmyid = #"user1#domain";
NSString *strBuddy = #"user2#domain";
NSManagedObjectContext *moc = [[self appDelegate] managedObjectContext_message_achiving];
NSEntityDescription *entity = [NSEntityDescription entityForName:#"XMPPMessageArchiving_Message_CoreDataObject"
inManagedObjectContext:moc];
NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init];
fetchRequest.predicate = [NSPredicate predicateWithFormat:#"bareJidStr = %# OR bareJidStr = %#", strmyid, strBuddy];
[fetchRequest setEntity:entity];
NSError *error;
NSArray *messagesArray = [moc executeFetchRequest:fetchRequest error:&error];
[messagesArray enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {
id messageObject = [messagesArray objectAtIndex:idx];
if ([messageObject isKindOfClass:[XMPPMessageArchiving_Message_CoreDataObject class]]) {
XMPPMessageArchiving_Message_CoreDataObject *currentMessageCoreDataObject = (XMPPMessageArchiving_Message_CoreDataObject*)messageObject;
XMPPMessage *message = currentMessageCoreDataObject.message;
if (message!=nil) {
[messages addObject:message];
}
}
}];
}
You can use like that
-(void)testMessageArchiving {
NSString *strmyid = #"myid";
NSString *strBuddy ="toid";
NSLog(#"my id and buddy is is %# and %#",strmyid,strBuddy);
XMPPMessageArchivingCoreDataStorage *storage = [XMPPMessageArchivingCoreDataStorage sharedInstance];
NSManagedObjectContext *moc = [storage mainThreadManagedObjectContext];
NSEntityDescription *entityDescription = [NSEntityDescription entityForName:#"XMPPMessageArchiving_Message_CoreDataObject"
inManagedObjectContext:moc];
NSFetchRequest *request = [[NSFetchRequest alloc]init];
request.predicate = [NSPredicate predicateWithFormat:#"bareJidStr = %# OR bareJidStr = %#", strmyid, strBuddy];
NSError *error;
NSArray *messages = [moc executeFetchRequest:request error:&error];
// NSLog(#"the history of messages is %#",messages);
[self print:[[NSMutableArray alloc]initWithArray:messages]];
I am New to Core Data.I have Developed an application. In my application i am having Registration, Login, Forgot password Forms.
In Registration Form i Write this code for registration.
NSEntityDescription *entitydesc = [NSEntityDescription entityForName:#"User" inManagedObjectContext:context];
NSManagedObject *newuser = [[NSManagedObject alloc]initWithEntity:entitydesc insertIntoManagedObjectContext:context];
[newuser setValue:self.registerUsername.text forKey:#"username"];
[newuser setValue:self.registerPassword.text forKey:#"password"];
[newuser setValue:self.registerConfirmPassword.text forKey:#"confirmpassword"];
[newuser setValue:self.registerMobileNumber.text forKey:#"mobilenumber"];
NSError *error;
[context save:&error];
In Login Form i write this Code:
NSEntityDescription *entitydesc = [NSEntityDescription entityForName:#"User" inManagedObjectContext:context];
NSFetchRequest *request = [[NSFetchRequest alloc]init];
[request setEntity:entitydesc];
NSPredicate *predicate = [NSPredicate predicateWithFormat:#"username like %# and password like %#",self.logUsername.text,self.logPassword.text];
[request setPredicate:predicate];
NSError *error;
NSArray *matchingData = [context executeFetchRequest:request error:&error];
if(matchingData.count<=0)
{
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:#"Error!" message:#"Username and password does not match" delegate:self cancelButtonTitle:#"OK" otherButtonTitles: nil];
[alert show];
}
else
{
NSString *username;
NSString *password;
for(NSManagedObject *obj in matchingData)
{
username = [obj valueForKey:#"username"];
password = [obj valueForKey:#"password"];
}
SecurityHome *securityhome = [[SecurityHome alloc]init];
[self.navigationController pushViewController:securityhome animated:YES];
}
}
Both were Working fine. Now i want to Display Password in Forgot password page if the user entered Username and Mobile number Correctly.How Can i Achieve this?
Set example predicate and sort orderings...
NSNumber *minimumSalary = ...;
NSPredicate *predicate = [NSPredicate predicateWithFormat:
#"(lastName LIKE[c] 'Worsley') AND (salary > %#)", minimumSalary];
[request setPredicate:predicate];
NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc]
initWithKey:#"firstName" ascending:YES];
[request setSortDescriptors:[NSArray arrayWithObject:sortDescriptor]];
[sortDescriptor release];
NSError *error = nil;
NSArray *array = [moc executeFetchRequest:request error:&error];
if (array == nil)
{
// Deal with error...
}
You should have done some 'googling' before asking this question. Any how,Let me do it for you. Here you go.
Core Data NSFetchResult guide for developer
Ray wenderlich- Really nice tutorial
In both of the listed links, I am trying to suggest NSFetchResultControllers, as they are fast & easy. Here you can see the difference
Without NSFetchResultController,
NSManagedObjectContext *moc = [self managedObjectContext];
NSEntityDescription *entityDescription = [NSEntityDescription
entityForName:#"Employee" inManagedObjectContext:moc];
NSFetchRequest *request = [[[NSFetchRequest alloc] init] autorelease];
[request setEntity:entityDescription];
// Set example predicate and sort orderings...
NSNumber *minimumSalary = ...;
NSPredicate *predicate = [NSPredicate predicateWithFormat:
#"(lastName LIKE[c] 'Worsley') AND (salary > %#)", minimumSalary];
[request setPredicate:predicate];
NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc]
initWithKey:#"firstName" ascending:YES];
[request setSortDescriptors:[NSArray arrayWithObject:sortDescriptor]];
[sortDescriptor release];
NSError *error = nil;
NSArray *array = [moc executeFetchRequest:request error:&error];
if (array == nil)
{
// Deal with error...
}
With NSFetchresultController
[[self managedObjectContext] fetchObjectsForEntityName:#"Employee" withPredicate:
#"(lastName LIKE[c] 'Worsley') AND (salary > %#)", minimumSalary];
These examples are for Famous employee table. Translate the code as per your requirement. If you are unable to work around with this code for any reason, let me know..
You can use this code for fetching details and pass the object to Forgot class and show there.
-(User*)getUserCredentialDetails:(NSUInteger)mobilenumber
{
NSError *error = nil;
NSFetchRequest *request = [[NSFetchRequest alloc] init];
NSEntityDescription *entity = [NSEntityDescription entityForName:#"User" inManagedObjectContext:managedObjectContext];
[request setEntity:entity];
NSPredicate *predicate = [NSPredicate predicateWithFormat:#"mobilenumber = %d",mobileNumber];
[request setPredicate:predicate];
NSArray * resultArray = [managedObjectContext executeFetchRequest:request error:&error];
[request release];
if (error != nil)
{
NSLog(#"Unresolved error %#, %#", error, [error userInfo]);
}
return [resultArray lastObject];
}
