creating chat room in QuickBlox

问题

I am trying to create a chat room in QuickBlox using my iOS app.

[[QBChat instance] createPrivateRoomWithName:@"My Room"];


- (void)createPrivateRoomWithName:(QBChatRoom*)room{
    NSLog(@"Private room %@ was created", room.name);

    // Add users to this room
    NSNumber *anny = [NSNumber numberWithInt:300];
    NSNumber *jim = [NSNumber numberWithInt:357];
    NSArray *users = [NSArray arrayWithObjects:anny, jim, nil];

    [[QBChat instance] addUsers:users toRoom:room];
}

but after using this code my application is crashing, below is the crash log.

回答1:

You have to login to QuickBlox Chat before creating room.

The solution is:

1) you have to add -ObjC flag to Other Linker Flags

2) Add to SplashController.h chat delegate QBChatDelegate

@interface SplashController : UIViewController <QBActionStatusDelegate, FBServiceResultDelegate, FBSessionDelegate, QBChatDelegate>{

3) Add to SplashController.m,

to if

}else if([result isKindOfClass:[QBMRegisterSubscriptionTaskResult class]]){

at the top next lines:

    // Login to QuickBlox Chat
    //
    [[QBChat instance] setDelegate:self];
    [DataManager shared].currentQBUser.password = [NSString stringWithFormat:@"%u", [[[DataManager shared].currentFBUser objectForKey:kId] hash]];
    [[QBChat instance] loginWithUser:[DataManager shared].currentQBUser];
    //
    //

4) Finally, add to the end

#pragma mark-
#pragma mark QBChatDelegate

- (void)chatDidLogin{
    [[QBChat instance] createPrivateRoomWithName:@"ChatRRoom"];
}

- (void)chatRoomDidCreate:(QBChatRoom *)room{
    NSLog(@"Room did create %@", room);
    myRoom = [room retain];
}

Just Add -ObjC flag in Other Linker Flags in your targets' settings. Hope it will solve your problem.
