環(huán)信SDK集成
請(qǐng)參考iOS開發(fā)-在現(xiàn)有項(xiàng)目中集成環(huán)信SDK及EaseUI或者參考官方文檔
此操作只針對(duì)已集成環(huán)信聊天
聊天頭像的設(shè)置
聊天頭像設(shè)置就是在聊天對(duì)象中攜帶用戶信息的相關(guān)參數(shù)，我們使用EMMessage中的擴(kuò)展字段ext攜帶用戶信息
我們創(chuàng)建一個(gè)EMUserInfo的用戶信息類
- EMUserInfo.h
@interface EMUserInfo : NSObject
/*!
用戶環(huán)信ID(環(huán)信賬號(hào))
*/
+ (NSString *)current_id_user;
/*!
用戶頭像的URL
*/
+ (NSString *)current_heading_user;
/*!
用戶昵稱
*/
+ (NSString *)current_name_user;
/**
當(dāng)前用戶信息
@return 用戶信息字典
*/
+ (NSDictionary *)currentUserInfo;
@end
- EMUserInfo.m
/*!
用戶ID
*/
+ (NSString *)current_id_user {
return @"獲取本地保存的環(huán)信賬號(hào)";
}
/*!
用戶頭像的URL
*/
+ (NSString *)current_heading_user {
return @"獲取本地保存的用戶頭像";
}
/*!
用戶昵稱
*/
+ (NSString *)current_name_user {
return @"獲取本地保存的用戶昵稱";
}
// 在APP登陸或者獲取用戶信息的時(shí)候，需要保存相關(guān)信息
+ (NSDictionary *)currentUserInfo {
return @{@"from_id_user":@"獲取本地保存的環(huán)信賬號(hào)",
@"from_name_user":@"獲取本地保存的用戶昵稱",
@"from_heading_user":@"獲取本地保存的用戶頭像"
};
}
- 在發(fā)送消息的時(shí)候攜帶用戶信息
EaseMessageViewController.m中- (void)sendMessage:(EMMessage *)message isNeedUploadFile:(BOOL)isUploadFile添加相關(guān)代碼
message.ext = [EMUserInfo currentUserInfo];
在發(fā)送消息的時(shí)候攜帶用戶信息
- 聊天頁面
新建一個(gè)控制器BSChatViewController繼承EaseMessageViewController
相關(guān)代碼
- (void)viewDidLoad {
[super viewDidLoad];
// 設(shè)置EaseMessageViewControllerDataSource的代理
self.dataSource = self;
}
#pragma mark - EaseMessageViewControllerDataSource
- (id<IMessageModel>)messageViewController:(EaseMessageViewController *)viewController modelForMessage:(EMMessage *)message {
id<IMessageModel> model = nil;
model = [[EaseMessageModel alloc] initWithMessage:message];
if (model.isSender) {//自己發(fā)送
//頭像
model.avatarURLPath = [EMUserInfo current_heading_user];
//昵稱
model.nickname = [EMUserInfo current_name_user];
//頭像占位圖
model.avatarImage = kPlaceholderImage;
}else{//對(duì)方發(fā)送
model.avatarImage = kPlaceholderImage;
//頭像
model.avatarURLPath = message.ext[@"from_heading_user"];
//昵稱
model.nickname = @"";
}
return model;
}
會(huì)話列表頁面頭像設(shè)置
需要做本地存儲(chǔ)：存儲(chǔ)的時(shí)機(jī)就是進(jìn)入聊天頁面的時(shí)候把對(duì)方的相關(guān)信息保存下來
在EMUserInfo中添加如下代碼
EMUserInfo.h
/**
本地保存對(duì)方聊天信息
@param userId 環(huán)信賬號(hào)
@param userName 用戶名
@param avatarURLPath 頭像
*/
+ (void)saveToUserInfo:(NSString *)userId name:(NSString *)userName avatarURLPath:(NSString *)avatarURLPath;
/**
查找本地用戶信息
@param userId 環(huán)信賬號(hào)
@return 信息字典
*/
+ (NSDictionary *)findUserInfoByUserId:(NSString *)userId;
EMUserInfo.m
+ (void)saveToUserInfo:(NSString *)userId name:(NSString *)userName avatarURLPath:(NSString *)avatarURLPath {
NSString *filePatch = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)objectAtIndex:0]stringByAppendingPathComponent:@"messageList.plist"];
NSMutableArray *array =[[NSMutableArray alloc] initWithContentsOfFile:filePatch];
if (!array) {
array = [NSMutableArray array];
}
NSDictionary *toDict = @{@"from_id_user":userId,
@"from_name_user":userName,
@"from_heading_user":avatarURLPath
};
if (![array containsObject:toDict]) {
[array addObject:toDict];
[array writeToFile:filePatch atomically:true];
}
}
+ (NSDictionary *)findUserInfoByUserId:(NSString *)userId {
NSString *filePatch = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)objectAtIndex:0]stringByAppendingPathComponent:@"messageList.plist"];
NSMutableArray *array =[[NSMutableArray alloc] initWithContentsOfFile:filePatch];
NSDictionary *tempDict;
for (NSDictionary *dict in array) {
if ([dict[@"from_id_user"] isEqualToString:userId]) {
tempDict = dict;
break;
}
}
return tempDict;
}
新建BSMessageListViewController繼承EaseConversationListViewController
相關(guān)代碼
- (void)viewDidLoad {
[super viewDidLoad];
// 設(shè)置EaseConversationListViewControllerDataSource的代理
self.dataSource = self;
}
- (id<IConversationModel>)conversationListViewController:(EaseConversationListViewController *)conversationListViewController
modelForConversation:(EMConversation *)conversation {
EaseConversationModel *model = [[EaseConversationModel alloc] initWithConversation:conversation];
if (model.conversation.type == EMConversationTypeChat) {
NSDictionary *dict = conversation.lastReceivedMessage.ext;
if(dict[@"from_name_user"] == nil || dict[@"from_heading_user"] == nil){
NSDictionary *localDict = [EMUserInfo findUserInfoByUserId:conversation.conversationId];
model.title = [localDict objectForKey:@"from_name_user"];
model.avatarURLPath = [localDict objectForKey:@"from_heading_user"];
model.avatarImage = kPlaceholderImage;
}else{
model.title = dict[@"from_name_user"];
model.avatarURLPath = dict[@"from_heading_user"];
//頭像占位圖
model.avatarImage = kPlaceholderImage;
}
}
return model;
}
這樣就實(shí)現(xiàn)了會(huì)話列表頭像和聊天界面頭像的展示
