身为一个环信小白,要利用环信集成聊天功能要怎么办呢?
当然首先是去看官方文档咯!下载SDk~
首先你要注册环信的账号,没有账号怎么聊天,鬼知道发给谁!
当时不知道是不是因为模拟器的原因还是网的问题始终不能注册环信账号,只好用真机来跑,一下就成功了:
注册模式分两种,开放注册和授权注册。
EMError *error = [[EMClient sharedClient] registerWithUsername:@"8001" password:@"111111"];
if (error==nil) {
NSLog(@"注册成功");
}
登录:调用 SDK 的登录接口进行的操作。
EMError *error = [[EMClient sharedClient] loginWithUsername:@"8001" password:@"111111"];
if (!error) {
NSLog(@"登录成功");
}
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
{
//这个很重要,不然SDK无法判断你的程序是在前台还是后台,如果没有设置,那么消息离线推送将不能成功
//简直大坑,都不跟我有什么用,开始就没用,导致利息那推送哪里用好长的时间;
[[EMClient sharedClient] applicationDidEnterBackground:application];
对于消息的接受就是下面的代理方法了,但是要注意的是一定要移除通知,不然在其他的界面就无法接受到消息的回调了,如果被注册了多次,那么你的聊天界面会很好看,全是重复的消息,不要问我为什么,想哭。
}
// APP将要从后台返回
- (void)applicationWillEnterForeground:(UIApplication *)application
{
[[EMClient sharedClient] applicationWillEnterForeground:application];
}
//消息回调:EMChatManagerChatDelegate因为不想自己去写逻辑,所以用的是EaseUI来完成的聊天,但是头像部分还是自己写的逻辑:
//移除消息回调
[[EMClient sharedClient].chatManager removeDelegate:self];
//注册消息回调
[[EMClient sharedClient].chatManager addDelegate:self delegateQueue:nil];
- (id<IMessageModel>)messageViewController:(EaseMessageViewController *)viewController modelForMessage:(EMMessage *)message {
// 用户可以根据自己的用户体系,根据message设置用户昵称和头像.
id<IMessageModel> model =nil;
model = [[EaseMessageModelalloc] initWithMessage:message];
model.avatarImage = [UIImageimageNamed:@"1.jpg"];// 默认头像
model.avatarURLPath = [HuanshiUserhuanshiUser].logo_url;// 头像网络地址
model.nickname =@""; // 用户昵称
if (!model.isSender) {
model.nickname =@"";
model.avatarURLPath =self.comment.logo_url;
}
return model;
}
聊天列表的展示逻辑是自己写的,大部分的时间都是在头像和最后一句消息的展示上:
EMConversation *conversation =self.conversationData[indexPath.section];
EMMessage *lastMessage = [conversationlatestMessage];
EMMessage *lastRecivedMessage = [conversationlastReceivedMessage];
if (!lastRecivedMessage) {
NSString *nickname = [[NSUserDefaultsstandardUserDefaults] objectForKey:[NSStringstringWithFormat:@"%@%@", conversation.conversationId,@"user_nick"]];
cell.titleLabel.text = nickname;
NSString *avatar = [[NSUserDefaultsstandardUserDefaults] objectForKey:[NSStringstringWithFormat:@"%@%@", conversation.conversationId,@"user_avatar"]];
[cell.avatarView.imageViewsd_setImageWithURL:[NSURLURLWithString:avatar]];
} else {
cell.titleLabel.text = lastRecivedMessage.ext[@"user_nick"];
[cell.avatarView.imageViewsd_setImageWithURL:lastRecivedMessage.ext[@"user_avatar"]];
}
EaseMessageModel *model = [[EaseMessageModelalloc] initWithMessage:lastMessage];
cell.detailLabel.text = model.text;
cell.timeLabel.text = [NSStringstringWithFormat:@"%@ %@",[selftimeTransformTimesTemp:lastMessage.timestamp], [selftempsTranformTime:lastMessage.timestamp]];
cell.avatarView.badge = conversation.unreadMessagesCount;
cell.avatarView.imageView.layer.cornerRadius = 30;
cell.avatarView.imageView.clipsToBounds =YES;
至于消息的推送环信能用离线推送和本地通知,离线推送可参考官方文档很详细;本地通知并没有讲得很详细:当时也是困扰了很久
当程序刚刚进入后台的时候,程序并没有被杀死,这个时候发来的消息会走我们之前设置的那个接收消息的代理方法,在这个方法里处理本地通知:
在appdelegate里完成的,你也可以在rootViewController中来写,是一样的
- (void)messagesDidReceive:(NSArray *)aMessages {
[[NSNotificationCenterdefaultCenter] postNotificationName:YXMessagesDidReceiveobject:nil];
if ([UIApplicationsharedApplication].applicationState ==UIApplicationStateBackground) {
[selfshowNotificationWithMessage:[aMessageslastObject]];
}
[selfupdateTotalUnreadMessageCount];
}
- (void)showNotificationWithMessage:(EMMessage *)message {
// 本地推送
EaseMessageModel *easeMessageModel = [[EaseMessageModelalloc] initWithMessage:message];
if (IS_iOS10) {
//因为适配了IOS10 所以舍弃了iOS8一下的,有需要的可以自己加上
UNUserNotificationCenter *userNotificationCenter = [UNUserNotificationCentercurrentNotificationCenter];
UNMutableNotificationContent *mutableNotificationContent = [[UNMutableNotificationContentalloc] init];
mutableNotificationContent.body = [[NSStringalloc] initWithFormat:@"%@:%@", message.ext[@"user_nick"], easeMessageModel.text];
mutableNotificationContent.sound = [UNNotificationSounddefaultSound];
UNTimeIntervalNotificationTrigger* trigger = [UNTimeIntervalNotificationTriggertriggerWithTimeInterval:0.1repeats:NO];
UNNotificationRequest *request = [UNNotificationRequestrequestWithIdentifier:@"now"content:mutableNotificationContenttrigger:trigger];
[userNotificationCenter addNotificationRequest:requestwithCompletionHandler:^(NSError *_Nullable error) {
if (!error) {
HSLog(@"本地推送成功");
}
}];
} else {
UILocalNotification *notification = [[UILocalNotificationalloc] init];
notification.fireDate = [NSDatedate];
notification.repeatCalendar = [NSCalendarcurrentCalendar];
notification.alertBody = [[NSStringalloc] initWithFormat:@"%@:%@", message.ext[@"user_nick"], easeMessageModel.text];
notification.alertAction =NSLocalizedString(@"open",@"Open");
notification.timeZone = [NSTimeZonedefaultTimeZone];
notification.repeatInterval =0;
NSMutableDictionary *userInfo = [NSMutableDictionarydictionary];
notification.userInfo = userInfo;
notification.alertLaunchImage =@"Default";
notification.soundName =@"msg.caf";
[[UIApplicationsharedApplication] scheduleLocalNotification:notification];
}
}
大致的我遇到的问题就是这些了,还有就是要和安卓那边对应好字段,比如消息的拓展,不然就不能喝安卓手机对聊啦!
