环信集成 2---基于环信Demo3.0，实现单聊功能

这几天在做环信，所以把环信相关的东西拿过来，做个系统点的东西

注意：

1. 这里Demo集成的是带有实时语音功能的（libEaseMobClientSDK.a）。
2. 环信库是直接拖拽EaseMobSDK文件夹到项目内的，没有使用pod管理。

最终效果

添加环信SDK

1. 下载环信SDK 2.2.1
   链接地址
   

   1
2. 添加EaseMobSDK到项目中，并添加依赖库。这里需要注意的地方:libEaseMobClientSDKLite.a不包含实时语音功能，libEaseMobClientSDK.a包含所有功能。必须要删掉一个，否则会报错。这里删除libEaseMobClientSDKLite.a。
3. 添加依赖库。参见官方文档

4. 新创建一个pch，并在Build Settings中添加配置。
   在pch中，导入头文件。

   #ifndef PrefixHeader_pch
   #define PrefixHeader_pch
   #import "EaseMob.h"
   #endif /* PrefixHeader_pch */

添加环信EaseUI

1. 导入EaseUI到项目中，并实现基础的登陆功能。
   找到Demo3.0的EaseUI目录，然后将如下文件，拖拽到项目中。并在pch文件中引入EaseUI.h

   #ifndef PrefixHeader_pch
   #define PrefixHeader_pch
   #import "EaseMob.h"
   #import "EaseUI.h"
   #endif /* PrefixHeader_pch */

   6
2. 在AppDelegate.m中注册环信的SDK和UI。
3. 在StoryBoard中新增一个按钮，并给予登陆方法。然后在方法中实现登陆功能。当登陆成功后,发送通知。收到通知后，跳转到UI提供的EaseMessageViewController界面。

其中APPDelegate中文件内容

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    //注册SDK
    [[EaseMob sharedInstance] registerSDKWithAppKey:@"easemob-demo#chatdemoui" apnsCertName:nil];
    //注册UI
    [[EaseSDKHelper shareHelper] easemobApplication:application
                      didFinishLaunchingWithOptions:launchOptions
                                             appkey:@"easemob-demo#chatdemoui"
                                       apnsCertName:nil
                                        otherConfig:@{kSDKConfigEnableConsoleLogger:[NSNumber numberWithBool:YES]}];
    [[EaseMob sharedInstance] application:application didFinishLaunchingWithOptions:launchOptions];
    return YES;
}

ViewController中的内容

- (IBAction)login:(id)sender {
    //用户名：zlanchun 密码：123456
    //异步登陆账号
    [[EaseMob sharedInstance].chatManager asyncLoginWithUsername:@"zlanchun" password:@"123456" completion:^(NSDictionary *loginInfo, EMError *error) {
         if (loginInfo && !error) {
             //发送自动登陆状态通知
             [[NSNotificationCenter defaultCenter] postNotificationName:KNOTIFICATION_LOGINCHANGE object:@YES];
         } else {
             NSLog(@"login error: %@",error);
         }
     } onQueue:nil];
}

- (void)jumpToChatVC {
    //创建聊天室 对象：zlanchun1
    EaseMessageViewController *chatController = [[EaseMessageViewController alloc] initWithConversationChatter:@"zlanchun1" conversationType:eConversationTypeChat];
    [self.navigationController pushViewController:chatController animated:YES];
}

继承Demo3.0中的功能

1. 首先导入Demo3.0中如下文件到项目中：
   

   7
2. 导入class里单聊功能ChatView到项目中
   

   8
3. 导入完成后的项目目录
   

   9
4. 添加头文件到PCH中。

   #ifndef PrefixHeader_pch
   #define PrefixHeader_pch
   //头文件
   #import "ChatDemoUIDefine.h"
   #import "EMAlertView.h"
   #import "TTGlobalUICommon.h"
   #import "UIViewController+DismissKeyboard.h"
   #import "NSString+Valid.h"
   #import "EaseMob.h"
   #import "EaseUI.h"
   #endif /* PrefixHeader_pch */

5. 注释未引用的文件，删除重复引用的文件，添加第三方库Parse的依赖。
   注释未引用的文件：

6. 在ViewController.m中应用头文件#import "ChatViewController.h"。然后在跳转方法中，注册跳转VC，跳转即可。

ViewController.m新增部分：

- (void)jumpToChatVC {
    //创建聊天室 对象：zlanchun1
    //EaseMessageViewController *chatController = [[EaseMessageViewController alloc] initWithConversationChatter:@"zlanchun1" conversationType:eConversationTypeChat];
    //创建基于Demo3.0Class的chatroom
    ChatViewController *chatController = [[ChatViewController alloc] initWithConversationChatter:@"zlanchun1" conversationType:eConversationTypeChat];
    [self.navigationController pushViewController:chatController animated:YES];
}

ChatViewController.m中需要注释的地方

#import "ChatViewController.h"
//#import "ChatGroupDetailViewController.h"
//#import "ChatroomDetailViewController.h"
#import "CustomMessageCell.h"
//#import "UserProfileViewController.h"
//#import "UserProfileManager.h"
//#import "ContactListSelectViewController.h"

- (void)messageViewController:(EaseMessageViewController *)viewController
   didSelectAvatarMessageModel:(id<IMessageModel>)messageModel
{
    //UserProfileViewController *userprofile = [[UserProfileViewController alloc] initWithUsername:messageModel.nickname];
    //[self.navigationController pushViewController:userprofile animated:YES];
}

- (id<IMessageModel>)messageViewController:(EaseMessageViewController *)viewController
                           modelForMessage:(EMMessage *)message
{
    id<IMessageModel> model = nil;
    model = [[EaseMessageModel alloc] initWithMessage:message];
    model.avatarImage = [UIImage imageNamed:@"EaseUIResource.bundle/user"];
//    UserProfileEntity *profileEntity = [[UserProfileManager sharedInstance] getUserProfileByUsername:model.nickname];
//    if (profileEntity) {
//        model.avatarURLPath = profileEntity.imageUrl;
//    }
    model.failImageName = @"imageDownloadFail";
    return model;
}

- (void)showGroupDetailAction
{
    [self.view endEditing:YES];
//    if (self.conversation.conversationType == eConversationTypeGroupChat) {
//        ChatGroupDetailViewController *detailController = [[ChatGroupDetailViewController alloc] initWithGroupId:self.conversation.chatter];
//        [self.navigationController pushViewController:detailController animated:YES];
//    }
//    else if (self.conversation.conversationType == eConversationTypeChatRoom)
//    {
//        ChatroomDetailViewController *detailController = [[ChatroomDetailViewController alloc] initWithChatroomId:self.conversation.chatter];
//        [self.navigationController pushViewController:detailController animated:YES];
//    }
}

- (void)transpondMenuAction:(id)sender
{
//    if (self.menuIndexPath && self.menuIndexPath.row > 0) {
//        id<IMessageModel> model = [self.dataArray objectAtIndex:self.menuIndexPath.row];
//        ContactListSelectViewController *listViewController = [[ContactListSelectViewController alloc] initWithNibName:nil bundle:nil];
//        listViewController.messageModel = model;
//        [listViewController tableViewDidTriggerHeaderRefresh];
//        [self.navigationController pushViewController:listViewController animated:YES];
//    }
    self.menuIndexPath = nil;
}

添加parse依赖库：

• StoreKit.framework
• Bolts.framework
• Parse.framework
• Accounts.framework
• Social.framework。
  其中Bolts.framework/Parse.framework在文件夹EaseClass/3rdparty/Parse下。

错误集合

• 报错1：未添加Parse依赖库引起的clang: error: linker command failed with exit code 1 (use -v to see invocation)错误。

  

  16

  解决办法：添加parse的依赖库，一共有5个（环信小哥告诉我有4个，结果，添加完4个依赖后，9个错误变成4个了。咋办？还好有Google，查parse依赖关系，发现15年7月份依赖增加了一个。）
  剩余的4个错误（"_OBJC_CLASS_$_SKPayment"）：

  看看国外小哥怎么说得(地址)。
