集成环信以及easeUI 的一堆坑

作者: LH_0811 | 来源:发表于2016-07-28 09:41 被阅读4674次

其实如果一个项目从一开始就集成环信以及UI还是相当简单的、难就难在项目已经成型后添加通讯功能。因为EaseUI中有几个常用的第三方库 MJRefresh SDWebImage 等。会跟自己项目中的冲突。

第一步：下载环信demo
http://downloads.easemob.com/downloads/ios_IM_sdk_V3.1.4.zip
第二步：拖文件

屏幕快照 2016-07-28 上午8.44.20.png

集成UI和基本的通讯功能这几个文件就够了，集成红包功能就加上RedacketSDK

还有重要的一步：把demo中的pch文件拷贝到自己的pch文件中,并且在自己所有的pch文件的头和尾添加

#ifdef __OBJC__
//
//
#endif

第一个坑来了

C++库编译不支持

//编译报错：
clang: error: invalid library name in argument '-stdlib=libstdc++ libc++'
clang: error: invalid library name in argument '-stdlib=libstdc++ libc++'

解决方法：按照demo中修改Build setting 中的

至此第一个坑填好

第二个坑：修改玩上面的坑可能会报错

解决方法：
把demo中的pch文件拷贝到自己的pch文件中,并且在自己所有的pch文件的头和尾添加

#ifdef __OBJC__
//
//
#endif

开始填第三个大坑：第二个坑填好后开始最蛋疼的一步，去除跟自己项目中重复的第三方库

我的项目中报错：当然这是我的项目不同项目可能会不一样，根据具体情况修改

屏幕快照 2016-07-28 上午9.03.48.png

很明显是MJRefresh报错，原因是因为这个项目中竟然集成的是老版本的MJRefresh'，环信的EaseUI中同样集成了MJRefresh，但是是新版的方法不太一样
解决方法：删掉EaseUI中的MjRefresh，修改报错代码。

直接Move to trush
修改后代码

屏幕快照 2016-07-28 上午9.09.18.png

改完MjRefresh MBProgressHUD 又报错，也是一样冲突了删了EaseUI中的MBProgressHUD 再编译
然后整个人都不好了

屏幕快照 2016-07-28 上午9.16.02.png
336个重复的文件。。。。一点点找
ld: 336 duplicate symbols for architecture x86_64
统计一下，
删掉了 MjRefresh ，MBProgressHUD（MBProgressHUD+Add保留了），DACircularProgress,MWPhotoBrowser ，PSTCollectionView
具体删除哪些东西还是根据自己的项目来定，重复就删掉不重复就留下。

至此我的坑填完了你的呢

至此应该已经把环信的通讯库以及UI集成到了我们的项目中下一步就是按照问道集成聊天界面了

先把环信初始化出来

照搬官方文档

初始化 SDK

第 1 步：引入相关头文件 #import “EMSDK.h”。

第 2 步：在工程的 AppDelegate 中的以下方法中，调用 SDK 对应方法。

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    //AppKey:注册的AppKey，详细见下面注释。
    //apnsCertName:推送证书名（不需要加后缀），详细见下面注释。
    EMOptions *options = [EMOptions optionsWithAppkey:@"douser#istore"];
    options.apnsCertName = @"istore_dev";
    [[EMClient sharedClient] initializeSDKWithOptions:options];
 
    return YES;
}
 
// APP进入后台
- (void)applicationDidEnterBackground:(UIApplication *)application
{
    [[EMClient sharedClient] applicationDidEnterBackground:application];
}
 
// APP将要从后台返回
- (void)applicationWillEnterForeground:(UIApplication *)application
{
    [[EMClient sharedClient] applicationWillEnterForeground:application];
}
调用的 SDK 接口参数解释如下：

AppKey: 区别 APP 的标识，参考开发者注册及管理后台。
apnsCertName: iOS 中推送证书名称，参考制作与上传推送证书。

初始化EaseUI 按照官网文档来

初始化

第 1 步：引入相关头文件 #import “EaseUI.h”。

第 2 步：在工程的 AppDelegate 中的以下方法中，调用 EaseUI 对应方法。

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
//官网文档写的这个方法 已经移除了
   /* [[EaseSDKHelper shareHelper] easemobApplication:application
                    didFinishLaunchingWithOptions:launchOptions
                                           appkey:@"douser#istore"
                                     apnsCertName:@"istore_dev"
                                      otherConfig:@{kSDKConfigEnableConsoleLogger:[NSNumber numberWithBool:YES]}];*/
//用这个方法
[[EaseSDKHelper shareHelper] hyphenateApplication
                    didFinishLaunchingWithOptions:launchOptions
                                           appkey:@"douser#istore"
                                     apnsCertName:@"istore_dev"
                                      otherConfig:@{kSDKConfigEnableConsoleLogger:[NSNumber numberWithBool:YES]}];
    return YES;

}

上面设置好以后就可以调用聊天界面的控制器了
在需要推出聊天界面的地方写上这个就行了
如果需要设置导航栏就在EaseMessageViewController.m 的viewdidload方法中添加设置导航栏的相关代码或方法就行

 EaseMessageViewController *chatController = [[EaseMessageViewController alloc] initWithConversationChatter:@"8001" conversationType:EMConversationTypeChat];
    chatController.title = @"8001";
    chatController.hidesBottomBarWhenPushed = YES;
    [self.navigationController pushViewController:chatController animated:YES];
    [tableView deselectRowAtIndexPath:indexPath animated:YES];

这边有个坑，就是在聊天界面点击表情报野指针错误

屏幕快照 2016-07-28 上午11.38.54.png

上图中的_emotionManagers是nil的
_emotionManagers实际是EaseMessageViewController中 EaseFacialView属性的一个表情管理器对应的是

屏幕快照 2016-07-28 上午11.48.25.png

我找遍这个类没有发现这个emotionManagers的初始化方法
由此可知，这个数组肯定是从外界传入的，如果不传入肯定是空的，所以当表情弹出的时候也就报野指针错误了。
解决方案有两种：
1.在 EaseMessageViewController 的viewdidload 方法中设置 self.EaseFacialView 的emotionManagers

//EaseMessageViewController.m
EaseEmotionManager * manager = [[EaseEmotionManager alloc] initWithType:EMEmotionDefault emotionRow:3 emotionCol:7 emotions:[EaseEmoji allEmoji]];
    [self.faceView setEmotionManagers:@[manager]];

2、在EaseFacialView类中添加emotionManagers 的懒加载,并将所有的_emotionManagers替换成self.emotionManagers 保证_emotionManagers随时都有值

#pragma mark -- 懒加载emotionManagers
- (NSArray *)emotionManagers{
    if (_emotionManagers == nil) {
        EaseEmotionManager * manager = [[EaseEmotionManager alloc] initWithType:EMEmotionDefault emotionRow:3 emotionCol:7 emotions:[EaseEmoji allEmoji]];
        _emotionManagers = @[manager];
    }
    return _emotionManagers;
}

Mark EaseConversationListViewControllerDataSource 集成环信EaseUI会话列表，不走数据源和代理方法

集成环信EaseUI会话列表，不走数据源和代理方法
解决方法，继承EaseConversationListViewControllerDataSource重写viewdidload

- (void)viewDidLoad {
    [super viewDidLoad];
    self.showRefreshHeader = YES;
    self.dataSource = self;
    [self tableViewDidTriggerHeaderRefresh];
    [self networkStateView];
    [self removeEmptyConversationsFromDB];

}

- (void)viewWillAppear:(BOOL)animated

{
    NSArray *conversations = [[EMClient sharedClient].chatManager getAllConversations];
    NSMutableArray *needRemoveConversations;
    for (EMConversation *conversation in conversations) {
        if (!conversation.latestMessage || (conversation.type == EMConversationTypeChatRoom)) {
            if (!needRemoveConversations) {
                needRemoveConversations = [[NSMutableArray alloc] initWithCapacity:0];
            }
            
            [needRemoveConversations addObject:conversation];
        }
    }
    
    if (needRemoveConversations && needRemoveConversations.count > 0) {
        [[EMClient sharedClient].chatManager deleteConversations:needRemoveConversations deleteMessages:YES];
    }
}

- (UIView *)networkStateView
{
    if (_networkStateView == nil) {
        _networkStateView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.tableView.frame.size.width, 44)];
        _networkStateView.backgroundColor = [UIColor colorWithRed:255 / 255.0 green:199 / 255.0 blue:199 / 255.0 alpha:0.5];
        
        UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(10, (_networkStateView.frame.size.height - 20) / 2, 20, 20)];
        imageView.image = [UIImage imageNamed:@"messageSendFail"];
        [_networkStateView addSubview:imageView];
        
        UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(CGRectGetMaxX(imageView.frame) + 5, 0, _networkStateView.frame.size.width - (CGRectGetMaxX(imageView.frame) + 15), _networkStateView.frame.size.height)];
        label.font = [UIFont systemFontOfSize:15.0];
        label.textColor = [UIColor grayColor];
        label.backgroundColor = [UIColor clearColor];
        label.text = NSLocalizedString(@"network.disconnection", @"Network disconnection");
        [_networkStateView addSubview:label];
    }
    
    return _networkStateView;
}

Mark 关于EaseMessageViewController 单聊界面复用消息显示不全

关于EaseMessageViewController 单聊界面复用有问题

单聊界面的Cell 一旦复用就不会再去计算宽度高度导致单元格显示内存不全以“...”省略掉了要显示的内容：如图所示

![ ![下拉刷新后.png](http:https://img.haomeiwen.com/i1540974/a5240d78e0d418eb.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240)](http:https://img.haomeiwen.com/i1540974/83488f603ec9b326.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240)

我尝试去看了EaseMessageCell中的代码。找到关于setModel的方法。但一时没有找到解决方案。
应急措施是去掉了单元格的重用
EaseMessageViewController.m中

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    id object = [self.dataArray objectAtIndex:indexPath.row];
    
    //time cell
    if ([object isKindOfClass:[NSString class]]) {

        EaseMessageTimeCell *timeCell = (EaseMessageTimeCell *)[tableView dequeueReusableCellWithIdentifier:TimeCellIdentifier];
        
        if (timeCell == nil) {
            timeCell = [[EaseMessageTimeCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:TimeCellIdentifier];
            timeCell.selectionStyle = UITableViewCellSelectionStyleNone;
        }
        
        timeCell.title = object;
        return timeCell;
    }
    else{
        id<IMessageModel> model = object;
        if (_delegate && [_delegate respondsToSelector:@selector(messageViewController:cellForMessageModel:)]) {
            UITableViewCell *cell = [_delegate messageViewController:tableView cellForMessageModel:model];
            if (cell) {
                if ([cell isKindOfClass:[EaseMessageCell class]]) {
                    EaseMessageCell *emcell= (EaseMessageCell*)cell;
                    if (emcell.delegate == nil) {
                        emcell.delegate = self;

}

Mark 更换自定义头像

环信并没有在他的服务器为我们存储用户信息，自定义头像要依赖于我们自己的用户体系。修改方法是在每个消息中添加一个Ext消息拓展，将用户的昵称以及头像放进去然后每次在显示聊天cell的时候给model赋值acatarPathUrl 以及NickName 没有拓展信息显示默认头像还环信用户名：需要修改的代码如下,
EaseMessageViewController.m中

pragma mark - send message中的代码凡是带有withExt:(NSDictionary*)ext的方法都对代码做如下修改.

 NSMutableDictionary * newExt = [NSMutableDictionary dictionaryWithDictionary:ext];
    newExt[@"avatar"]=[[NSUserDefaults standardUserDefaults] valueForKey:@"emAvatar"];
    newExt[@"nickname"]=[[NSUserDefaults standardUserDefaults] valueForKey:@"emNickname"];

改完之后：

到这一步所有发送出去的消息都已经拓展上了用户昵称和头像,然后修改方法

(NSArray *)formatMessages:(NSArray *)messages
使用自定义的头像和昵称


#pragma mark - public 

- (NSArray *)formatMessages:(NSArray *)messages
{
    NSMutableArray *formattedArray = [[NSMutableArray alloc] init];
    if ([messages count] == 0) {
        return formattedArray;
    }
    
    for (EMMessage *message in messages) {
        //Calculate time interval
        CGFloat interval = (self.messageTimeIntervalTag - message.timestamp) / 1000;
        if (self.messageTimeIntervalTag < 0 || interval > 60 || interval < -60) {
            NSDate *messageDate = [NSDate dateWithTimeIntervalInMilliSecondSince1970:(NSTimeInterval)message.timestamp];
            NSString *timeStr = @"";
            
            if (_dataSource && [_dataSource respondsToSelector:@selector(messageViewController:stringForDate:)]) {
                timeStr = [_dataSource messageViewController:self stringForDate:messageDate];
            }
            else{
                timeStr = [messageDate formattedTime];
            }
            [formattedArray addObject:timeStr];
            self.messageTimeIntervalTag = message.timestamp;
        }
        //Construct message model
        id<IMessageModel> model = nil;
        if (_dataSource && [_dataSource respondsToSelector:@selector(messageViewController:modelForMessage:)]) {
            model = [_dataSource messageViewController:self modelForMessage:message];
        }
        else{
            model = [[EaseMessageModel alloc] initWithMessage:message];
            model.avatarImage = [UIImage imageNamed:@"EaseUIResource.bundle/user"];
    //主要修改这一块代码
            if (message.ext!=nil) {
                if (message.ext[@"avatar"] != nil) {
                    model.avatarURLPath = message.ext[@"avatar"];
                }
                model.nickname =message.ext[@"nickname"];
            }
            model.failImageName = @"imageDownloadFail";
        }
        if (model) {
            [formattedArray addObject:model];
        }
    }
    return formattedArray;
}

集成环信以及easeUI 的一堆坑

还有重要的一步：把demo中的pch文件拷贝到自己的pch文件中,并且在自己所有的pch文件的头和尾添加

第一个坑来了

开始填第三个大坑：第二个坑填好后开始最蛋疼的一步，去除跟自己项目中重复的第三方库

先把环信初始化出来

这边有个坑，就是在聊天界面点击表情报野指针错误

Mark EaseConversationListViewControllerDataSource 集成环信EaseUI会话列表，不走数据源和代理方法

Mark 关于EaseMessageViewController 单聊界面复用消息显示不全

Mark 更换自定义头像

pragma mark - send message中的代码凡是带有withExt:(NSDictionary*)ext的方法都对代码做如下修改.

一句话总结环信集成大法！

拖Demo里的东西！
