iOS 环信3.2.3 集成聊天，语音，视频，通话

假定你已经集成了静态库，动态库，设置了bitcode，AppID绑定了推送，push Notifation 已经打开，接下来就是要实现聊天，视频，推送等等。

环信的demo一上来猛一看，很懵逼，没办法，一点点抠，把你需要的模块都抠出来，包括资源，图片，等等，[这里我只集成单聊，群组]。

1、把不用的全部删掉，（我主要把红包，聊天室，机器人相关的全部删除）。

还有记得 call 文件夹下的全部删除，废弃

2、pch 文件，已经国际化的配置，包括头文件的配置（我这里使用的全部的sdk 所以，DEMO_CALL 为 1）

3、最重要就是MainViewController的替换以及ChatDemoHelper的替换。

demo 里，根控制器是带NavBar 的TarbbarController，而TarbarController 又包含了三个子控制器。

针对项目结构自己做调整,头文件不用变，替换你需要的类

#import 
#import 
@interface LXTabbarController : UITabBarController
{
    EMConnectionState _connectionState;
}
- (void)jumpToChatList;

- (void)setupUntreatedApplyCount;

- (void)setupUnreadMessageCount;

- (void)networkChanged:(EMConnectionState)connectionState;

- (void)didReceiveLocalNotification:(UILocalNotification *)notification;

- (void)didReceiveUserNotification:(UNNotification *)notification;

- (void)playSoundAndVibration;

- (void)showNotificationWithMessage:(EMMessage *)message;
@end

.m 里 关于接口的方法可以直接拿demo的方法使用，只是在配置子控制的地方自己设置。

#pragma mark - 添加所有的子控制器
- (void)addAllChildViewControllers {
    //
    // 
    _chatListVC= [[ConversationListController alloc] init];
     [_chatListVC networkChanged:_connectionState];
    [self addOneChildViewController:_chatListVC image:[UIImage imageNamed:@"tabbar_chats"] selectedImage:[UIImage imageNamed:@"tabbar_chatsHL"] title:@"会话"];
    
    // 
    _contactsVC = [[ContactListViewController alloc] init];
    [self addOneChildViewController:_contactsVC image:[UIImage imageNamed:@"tabbar_contacts"]
                      selectedImage:[UIImage imageNamed:@"tabbar_contactsHL"] title:@"通讯录"];
    
    
    
    // 
    FourViewController *businessVc = [[FourViewController alloc] init];
    [self addOneChildViewController:businessVc image:[UIImage imageNamed:@"tabbar_setting"] selectedImage:[UIImage imageNamed:@"tabbar_settingHL@2x"] title:@"设置"];
    
}

#pragma mark - 添加一个子控制器
- (void)addOneChildViewController:(UIViewController *)viewController image:(UIImage *)image selectedImage:(UIImage *)selectedImage title:(NSString *)title {
    UINavigationController *navC = [[UINavigationController alloc] initWithRootViewController:viewController];
    navC.navigationBar.barTintColor = [UIColor colorWithRed:0.47 green:0.83 blue:0.98 alpha:1];
    NSMutableDictionary *attributes = [NSMutableDictionary dictionary];
    attributes[NSForegroundColorAttributeName] = [UIColor colorWithWhite:0.996 alpha:1.000];
    navC.navigationBar.titleTextAttributes = attributes;
    navC.tabBarItem.title = title;
    navC.tabBarItem.image = image;
    navC.tabBarItem.titlePositionAdjustment = UIOffsetMake(0, -3);
    
    navC.tabBarItem.selectedImage = selectedImage;
    
    [self addChildViewController:navC];
}

如果你也是和我一样，使用Tabbar 配置Navbar的结构，有个地方需要注意：

4、最重要的是把ChatDemoHelper里修改一下

Help接口.png

替换所有的MainViewController，设置MainController

#import "ChatDemoHelper.h"

#import "AppDelegate.h"
#import "ApplyViewController.h"
#import "MBProgressHUD.h"

#import "EaseSDKHelper.h"



#if DEMO_CALL == 1
#import "DemoCallManager.h"
#endif

static ChatDemoHelper *helper = nil;

@implementation ChatDemoHelper

+ (instancetype)shareHelper
{
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        helper = [[ChatDemoHelper alloc] init];
    });
    return helper;
}

- (void)dealloc
{
    [[EMClient sharedClient] removeDelegate:self];
    [[EMClient sharedClient].groupManager removeDelegate:self];
    [[EMClient sharedClient].contactManager removeDelegate:self];
    [[EMClient sharedClient].roomManager removeDelegate:self];
    [[EMClient sharedClient].chatManager removeDelegate:self];
}

- (id)init
{
    self = [super init];
    if (self) {
        [self initHelper];
    }
    return self;
}

#pragma mark - setter

- (void)setMainVC:(LXTabbarController *)mainVC
{
    _mainVC = mainVC;
    
#if DEMO_CALL == 1
    [[DemoCallManager sharedManager] setMainController:mainVC];
#endif
}

#pragma mark - init

- (void)initHelper
{

    
    [[EMClient sharedClient] addDelegate:self delegateQueue:nil];
    [[EMClient sharedClient].groupManager addDelegate:self delegateQueue:nil];
    [[EMClient sharedClient].contactManager addDelegate:self delegateQueue:nil];
    [[EMClient sharedClient].roomManager addDelegate:self delegateQueue:nil];
    [[EMClient sharedClient].chatManager addDelegate:self delegateQueue:nil];
#if DEMO_CALL == 1
    [DemoCallManager sharedManager];
#endif

}

剩下的 和Demo中直接复制过来。

最后说一下环信的推送：

环信的推送应用在后台是不会推送的，需要在接收消息的地方，判断当前应用的活跃状态，然后做本地推送。

- (void)didReceiveMessages:(NSArray *)aMessages
{
    BOOL isRefreshCons = YES;
    for(EMMessage *message in aMessages){
        BOOL needShowNotification = (message.chatType != EMChatTypeChat) ? [self _needShowNotification:message.conversationId] : YES;
        

        UIApplicationState state = [[UIApplication sharedApplication] applicationState];
        if (needShowNotification) {
#if !TARGET_IPHONE_SIMULATOR
            switch (state) {
                case UIApplicationStateActive:
                    [self.mainVC playSoundAndVibration];
                    break;
                case UIApplicationStateInactive:
                    [self.mainVC playSoundAndVibration];
                    break;
                case UIApplicationStateBackground:
                    [self.mainVC showNotificationWithMessage:message];
                    break;
                default:
                    break;
            }
#endif
        }
        
        if (_chatVC == nil) {
            _chatVC = [self _getCurrentChatView];
        }
        BOOL isChatting = NO;
        if (_chatVC) {
            isChatting = [message.conversationId isEqualToString:_chatVC.conversation.conversationId];
        }
        if (_chatVC == nil || !isChatting || state == UIApplicationStateBackground) {
            [self _handleReceivedAtMessage:message];
            
            if (self.conversationListVC) {
                [_conversationListVC refresh];
            }
            
            if (self.mainVC) {
                [_mainVC setupUnreadMessageCount];
            }
            return;
        }
        
        if (isChatting) {
            isRefreshCons = NO;
        }
    }
    
    if (isRefreshCons) {
        if (self.conversationListVC) {
            [_conversationListVC refresh];
        }
        
        if (self.mainVC) {
            [_mainVC setupUnreadMessageCount];
        }
    }
}

好了，基本功能都实现了。
