I've integrated following library from Cocoapods, You may find the code and its sample code at https://github.com/EugeneNguyen/XBChatModule
pod 'XBChatModule'
This library is used to integrate XMPP Chat in Xcode project. I also added suggested code from its ReadMe file. For your reference I am pasting it below
AppDelegate.m
[[XBChatModule sharedInstance] setUsername:@"admin"];
[[XBChatModule sharedInstance] setPassword:@"admin"];
[[XBChatModule sharedInstance] setHost:@"sflashcard.com"];
[[XBChatModule sharedInstance] connect];
[[XBChatModule sharedInstance] setAvatarFormat:@"http://dev.sflashcard.com/images/mantis_logo.png?test=%@"];
[[XBChatModule sharedInstance] setAvatarPlaceHolder:[UIImage imageNamed:@"girl_9"]];
The View controller is inherited from XBMessageViewController
ViewController.m
- (void)viewDidLoad
{
self.jidStr = @"binh.nx@sflashcard.com";
[super viewDidLoad];
}
- (void)viewWillAppear:(BOOL)animated
{
}
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(reloadData) name:@"XBChatModuleNewAvatar" object:nil];
}
- (void)viewDidDisappear:(BOOL)animated
{
[super viewDidDisappear:animated];
[[NSNotificationCenter defaultCenter] removeObserver:self];
}
- (void)reloadData
{
[self.collectionView performSelectorOnMainThread:@selector(reloadData) withObject:nil waitUntilDone:YES];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
The code works fine until I send a message. Whenever I press send button, it crashes the app by throwing following error in console

I understand it says, that I haven't implemented the function messageHash in Class XBMessage , but the same code works fine in the sample code that I download from Github. Kindly help me to solve this error.
