研究環(huán)信SDK也有一段時(shí)間了,之前看了下環(huán)信的官方文檔,寫(xiě)的很詳細(xì),我們只需要照葫蘆畫(huà)瓢就可以了,但是要獨(dú)立的完成以款即時(shí)通訊的app難度還是很大的,因?yàn)樾枰紤]的地方太多,工作量也很大,樓主上個(gè)月辭職了,正好可以靜下心來(lái)好好研究一下技術(shù),當(dāng)然做完這個(gè)項(xiàng)目還是要繼續(xù)找工作的(說(shuō)到這里 不得不吐槽一下,找工作的人真多呀),話不多說(shuō),開(kāi)干,我會(huì)每天在簡(jiǎn)書(shū)上更新,希望在成長(zhǎng)自己的同時(shí)能幫到一些朋友~
- 集成環(huán)信SDK,集成這一步官方文檔都寫(xiě)的很清楚了,我就不再贅述:
- SDK下載地址http://www.easemob.com/download/im
- 官方文檔:http://docs.easemob.com/start/300iosclientintegration/20iossdkimport
-
集成完后我們需要?jiǎng)h除兩個(gè)東西,這兩個(gè)是輕量級(jí)的SDK,里面功能有限,適合簡(jiǎn)單的測(cè)試,我們這里用完整版本的,所以我們進(jìn)入項(xiàng)目原文件把這兩個(gè)東西干掉:
-
這里要注意一下,如果刪除了輕量級(jí)的SDK,前面的配置就不能用這個(gè)輕量級(jí)的,必須用完整版的
- 萬(wàn)事俱備,可以開(kāi)干!,首先導(dǎo)入頭文件然后再初始化SDK,這些操作都在
AppDelegate.m中: - 導(dǎo)入頭文件
#import "EaseMob.h"
- 初始化
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
/**

*/
[[EaseMob sharedInstance] registerSDKWithAppKey:kEaseMobAppKey

}
- 集成完SDK后,先做生命周期的跟蹤
- 啟動(dòng)
- 進(jìn)入后臺(tái)
- 從后臺(tái)進(jìn)入前臺(tái)
- 銷毀

搭建登錄注冊(cè)界面,完成拖線:
注冊(cè)
- 注冊(cè)模式分兩種，開(kāi)放注冊(cè)和授權(quán)注冊(cè)。只有開(kāi)放注冊(cè)時(shí)，才可以客戶端注冊(cè)逮矛。
- 開(kāi)放注冊(cè)是為了測(cè)試使用，正式環(huán)境中不推薦使用該方式注冊(cè)環(huán)信賬號(hào)揽咕，授權(quán)注冊(cè)的流程應(yīng)該是您服務(wù)器通過(guò)環(huán)信提供的 REST API 注冊(cè)蟋座，之后保存到您的服務(wù)器或返回給客戶端勉失。
- 注冊(cè)提供了三種方法,在這里我們選擇第三種(IChatManagerDelegate 回調(diào)方法).
- 注冊(cè)步驟: 調(diào)用注冊(cè)接口 -> 添加代理 -> 遵守協(xié)議 -> 監(jiān)聽(tīng)回調(diào)方法,
ViewController.m中代碼如下:
//
// ViewController.m
// EMWeiChat
//
// Created by admin on 16/11/4.
// Copyright ? 2016年 冷洪林. All rights reserved.
//
#import "ViewController.h"
#import "EaseMob.h"
@interface ViewController () <EMChatManagerDelegate>
@property (weak, nonatomic) IBOutlet UITextField *usernameLabel;
@property (weak, nonatomic) IBOutlet UITextField *pwdLabel;
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
// 添加代理
[[EaseMob sharedInstance].chatManager addDelegate:self delegateQueue:nil];
}
// 登錄
- (IBAction)loginBtn:(id)sender {
}
// 注冊(cè)(代理回調(diào)方法注冊(cè))
- (IBAction)registerBtn:(id)sender {
// 接口調(diào)用
[[EaseMob sharedInstance].chatManager asyncRegisterNewAccount:self.usernameLabel.text password:self.pwdLabel.text];
}
// 監(jiān)聽(tīng)回調(diào)方法
- (void)didRegisterNewAccount:(NSString *)username password:(NSString *)password error:(EMError *)error
{
NSLog(@"%s", __func__);
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
@end
- 運(yùn)行程序,輸入注冊(cè)的賬號(hào)和密碼:
-
我們?cè)偃キh(huán)信后臺(tái)看看是否注冊(cè)成功
登錄
- 登錄：調(diào)用 SDK 的登錄接口進(jìn)行的操作。
- 提供了三種方法,這里我們采用第二種方法(block 異步方法):
// 登錄
- (IBAction)loginBtn:(id)sender {
[[EaseMob sharedInstance].chatManager asyncLoginWithUsername:self.usernameLabel.text password:self.pwdLabel.text completion:^(NSDictionary *loginInfo, EMError *error) {
if (!error && loginInfo) {
NSLog(@"登錄成功");
}
} onQueue:nil];
}
- 登錄過(guò)后而已看到登錄成功,但是這里也打印了一些xmpp控制臺(tái)的輸出信息,我們可以把它屏蔽掉
- 屏蔽方法:來(lái)到
AppDelegate.m:我們初始化SDK的時(shí)候有個(gè)參數(shù)是otherConfig,點(diǎn)擊該方法可以看到右邊的解釋:
- 把該參數(shù)改為@NO,就可以屏蔽啦~
清除控制臺(tái)輸出
登錄成功
退出登錄
退出登錄分兩種類型：主動(dòng)退出登錄和被動(dòng)退出登錄皂林。
主動(dòng)退出登錄：調(diào)用SDK的退出接口朗鸠；
被動(dòng)退出登錄：1. 正在登錄的賬號(hào)在另一臺(tái)設(shè)備上登錄蚯撩；2. 正在登錄的賬號(hào)被從服務(wù)器端刪除础倍。
退出登錄提供了三種方法,這里用第二種(block 異步方法)
logoffWithUnbindDeviceToken：是否解除 device token 的綁定，在被動(dòng)退出時(shí)傳 NO胎挎，在主動(dòng)退出時(shí)傳 YES沟启。
#pragma mark - 退出登錄
- (IBAction)loginOut:(id)sender {
/*
asyncLogoffWithUnbindDeviceToken:
主動(dòng)退出的時(shí)候,傳YES
被動(dòng)退出的時(shí)候,傳NO
被動(dòng)退出:
其他設(shè)備登錄
被服務(wù)器移除
// 退出，傳入YES犹菇，會(huì)解除device token綁定德迹，不再收到群消息；傳NO揭芍，不解除device token
*/
[[EaseMob sharedInstance].chatManager asyncLogoffWithUnbindDeviceToken:YES completion:^(NSDictionary *info, EMError *error) {
if (!error) {
NSLog(@"退出成功");
}
} onQueue:nil];
}
// 從其他設(shè)備登錄
- (void)didLoginFromOtherDevice
{
[[EaseMob sharedInstance].chatManager asyncLogoffWithUnbindDeviceToken:NO completion:^(NSDictionary *info, EMError *error) {
if (!error) {
NSLog(@"從其他設(shè)備登錄");
}
} onQueue:nil];
}
// 被服務(wù)器移除
- (void)didRemovedFromServer
{
[[EaseMob sharedInstance].chatManager asyncLogoffWithUnbindDeviceToken:NO completion:^(NSDictionary *info, EMError *error) {
if (!error) {
NSLog(@"被服務(wù)器移除");
}
} onQueue:nil];
}
自動(dòng)重連
- 當(dāng)?shù)艟€時(shí)胳搞，iOS SDK 會(huì)自動(dòng)重連，只需要監(jiān)聽(tīng)重連相關(guān)的回調(diào)称杨，無(wú)需進(jìn)行任何操作肌毅。
#pragma mark - 自動(dòng)重連
/*!
@method
@brief 將要發(fā)起自動(dòng)重連操作時(shí)發(fā)送該回調(diào)
@discussion
@result
*/
- (void)willAutoReconnect
{
NSLog(@"將要自動(dòng)重連");
}
/*!
@method
@brief 自動(dòng)重連操作完成后的回調(diào)（成功的話，error為nil姑原，失敗的話悬而，查看error的錯(cuò)誤信息）
@discussion
@result
*/
- (void)didAutoReconnectFinishedWithError:(NSError *)error
{
if (!error) {
NSLog(@"自動(dòng)重連成功");
}
}
- 在這里呢,我連接成功后就拔掉電腦網(wǎng)線模擬掉線的情況,然后再插上網(wǎng)線,可以看到控制臺(tái)打印:
自動(dòng)登錄
- 自動(dòng)登錄：即首次登錄成功后，不需要再次調(diào)用登錄方法锭汛，在下次 APP 啟動(dòng)時(shí)笨奠，SDK 會(huì)自動(dòng)為您登錄。并且如果您自動(dòng)登錄失敗唤殴，也可以讀取到之前的會(huì)話信息般婆。
- SDK 中自動(dòng)登錄屬性默認(rèn)是關(guān)閉的，需要您在登錄成功后設(shè)置朵逝，以便您在下次 APP 啟動(dòng)時(shí)不需要再次調(diào)用環(huán)信登錄腺兴，并且能在沒(méi)有網(wǎng)的情況下得到會(huì)話列表。
- 在登錄成功后設(shè)置自動(dòng)登錄
// 登錄
- (IBAction)loginBtn:(id)sender {
[[EaseMob sharedInstance].chatManager asyncLoginWithUsername:self.usernameLabel.text password:self.pwdLabel.text completion:^(NSDictionary *loginInfo, EMError *error) {
if (!error && loginInfo) {
NSLog(@"登錄成功");
// 設(shè)置自動(dòng)登錄
[[EaseMob sharedInstance].chatManager setIsAutoLoginEnabled:YES];
}
} onQueue:nil];
}
-
自動(dòng)登錄在以下幾種情況下會(huì)被取消：
用戶調(diào)用了 SDK 的登出動(dòng)作廉侧；
用戶在別的設(shè)備上更改了密碼页响，導(dǎo)致此設(shè)備上自動(dòng)登錄失敗段誊；
用戶的賬號(hào)被從服務(wù)器端刪除闰蚕；
用戶從另一個(gè)設(shè)備登錄，把當(dāng)前設(shè)備上登錄的用戶踢出连舍。 所以没陡，在您調(diào)用登錄方法前，應(yīng)該先判斷是否設(shè)置了自動(dòng)登錄，如果設(shè)置了盼玄，則不需要您再調(diào)用贴彼。
我們?cè)?code>AppDelegate.m的
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions方法中判斷:
BOOL isAutoLogin = [[EaseMob sharedInstance].chatManager isAutoLoginEnabled];
if (isAutoLogin) {
NSLog(@"切換根控制器");
}
- SDK中，如果發(fā)生自動(dòng)登錄埃儿，會(huì)有以下回調(diào)：
#pragma mark - 自動(dòng)登錄
- (void)willAutoLoginWithInfo:(NSDictionary *)loginInfo error:(EMError *)error
{
NSLog(@"將要自動(dòng)登錄");
}
- (void)didAutoLoginWithInfo:(NSDictionary *)loginInfo error:(EMError *)error
{
NSLog(@"已經(jīng)自動(dòng)登錄");
}
接下來(lái)我們就要進(jìn)行微信框架的搭建了
- 首先導(dǎo)入素材,設(shè)置AppIcon和LaunchImage, 這兩步比較簡(jiǎn)單,我就不細(xì)講了,如果有不清楚的朋友可以留言.如果大家有需要,后面我會(huì)講一下怎樣獲取到微信里面的圖片素材,之前有很多網(wǎng)友說(shuō)Assets.car里面的素材拿不到,別擔(dān)心,總是有方法的,后面再一一講解,我們現(xiàn)在主要把精力放在即時(shí)通訊上面,素材我也會(huì)貼上來(lái)的~
微信架構(gòu)搭建,這里我采用純代碼,storyboard適合頁(yè)面多的時(shí)候,像這種復(fù)雜的界面建議用純代碼加xib.
-
進(jìn)入文件夾,重構(gòu)一下文件,大家個(gè)人重構(gòu)習(xí)慣自由發(fā)揮
把文件拖入到工程中,注意我們之前在build setting中設(shè)置了Other Linker Flags,在我們重構(gòu)文件夾的時(shí)候改變了路徑,所以運(yùn)行會(huì)報(bào)錯(cuò):找不到libEaseMobClientSDK.a文件,所以我們需要再來(lái)到Other Linker Flags重新指定一下路徑:
- 創(chuàng)建文件:
(tabBar)LHLTabBarController->UITabBarController
(導(dǎo)航條)LHLNavViewController->UINavigationController
(微信模塊)LHLChatViewController->UITableViewController
(聯(lián)系人模塊)LHLContactViewController->UITableViewController
(發(fā)現(xiàn)模塊)LHLDiscoverViewController->UITableViewController
(我模塊)LHLMeViewController->UITableViewController
(登錄)LHLLoginViewController->UIViewController

有網(wǎng)友提到官方SDK集成的問(wèn)題,我之前以為大家跟著官方文檔一步步來(lái)就會(huì)沒(méi)問(wèn)題的,所以文章開(kāi)頭就直接放了官方文檔的連接,鑒于網(wǎng)友們的問(wèn)題,我接下來(lái)就從零開(kāi)始集成環(huán)信SDK 2.x 和 3.x,希望能幫到遇到困難的網(wǎng)友~
