3.课堂上创建过程
打开终端:(1)pod search EaseMob (2)cd + 文件夹的名字 (3) vim Podfile 打开编辑器 (4)pod 'Easemob', '~> 2.1.4’(5)Esc (6)shift+; 输入wq (8) pod update(9)导入 #import <EaseMob.h>
4.创建一个有登陆和注册页的storyBoard
在AppDelegate.m里面写
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
//初始化EaseMob
[[EaseMobsharedInstance] registerSDKWithAppKey:@"chenkai#bjs151251"apnsCertName:@"push"];
//启动完成
[[EaseMobsharedInstance] application:application didFinishLaunchingWithOptions:launchOptions];
//获取LoginAndRegister的Storyboard
UIStoryboard *loginStoryboard = [UIStoryboardstoryboardWithName:@"LoginAndRegist"bundle:nil];
//获取Storyboard里面的根视图控制器(模态到初始的Controller)
UIViewController *loginVC = [loginStoryboard instantiateInitialViewController];
//让loginStoryboard可见
[self.windowmakeKeyAndVisible];
//模态
[self.window.rootViewControllerpresentViewController:loginVC animated:YEScompletion:nil];
returnYES;
//初始化EaseMob
[[EaseMobsharedInstance] registerSDKWithAppKey:@"chenkai#bjs151251"apnsCertName:@"push"];
//启动完成
[[EaseMobsharedInstance] application:application didFinishLaunchingWithOptions:launchOptions];
//获取LoginAndRegister的Storyboard
UIStoryboard *loginStoryboard = [UIStoryboardstoryboardWithName:@"LoginAndRegist"bundle:nil];
//获取Storyboard里面的根视图控制器(模态到初始的Controller)
UIViewController *loginVC = [loginStoryboard instantiateInitialViewController];
//让loginStoryboard可见
[self.windowmakeKeyAndVisible];
//模态
[self.window.rootViewControllerpresentViewController:loginVC animated:YEScompletion:nil];
returnYES;
}
一.注册页面

}
五.聊天页面
.h文件
#import <UIKit/UIKit.h>
#import <EaseMob.h>
@interface ChatTableController : UITableViewController
///会话的TextField
@property (weak, nonatomic) IBOutletUITextField *chatField;
///好友属性
@property(nonatomic,strong)EMBuddy *buddy;
#import <EaseMob.h>
@interface ChatTableController : UITableViewController
///会话的TextField
@property (weak, nonatomic) IBOutletUITextField *chatField;
///好友属性
@property(nonatomic,strong)EMBuddy *buddy;
.m文件 这里需要用到一个类
#import "ChatTableController.h"
#import "MessageBody.h"

///消息列表
@property(nonatomic,strong)NSMutableArray *messageArray;
//发送消息

@end
六.创建的类
.h文件
#import <Foundation/Foundation.h>
#import <EaseMob.h>
@interface MessageBody : NSObject<IEMMessageBody>
@property (nonatomic, assign) MessageBodyType messageBodyType;
@property (nonatomic, strong, readonly) id<IEMChatObject> chatObject;
@property (nonatomic, weak) EMMessage *message;
- (id)initWithChatObject:(id<IEMChatObject>)aChatObject;
#import <EaseMob.h>
@interface MessageBody : NSObject<IEMMessageBody>
@property (nonatomic, assign) MessageBodyType messageBodyType;
@property (nonatomic, strong, readonly) id<IEMChatObject> chatObject;
@property (nonatomic, weak) EMMessage *message;
- (id)initWithChatObject:(id<IEMChatObject>)aChatObject;
@end
.m文件(这里是因为签订了协议必须实现这个方法)
#import "MessageBody.h"
@implementation MessageBody
- (id)initWithChatObject:(id<IEMChatObject>)aChatObject{
returnnil;
}
@implementation MessageBody
- (id)initWithChatObject:(id<IEMChatObject>)aChatObject{
returnnil;
}
@end
