前言：使用环信UI时需要显示用户的昵称、头像、点击头像进入用户主页。但是有的地方需要直接更改环信UI源码，使用cocoapods误更新环信UI时，源码更改的部分被覆盖。日狗两次，现记录更改流程，以备第三次。。。

1，在EaseMessageViewController.h中添加三个属性

#pragma mark -进入聊天界面时需要的用户昵称，头像，ID @property(nonatomic,strong)NSString*otherUserNick;

@property(nonatomic,strong)NSString*otherUserPic;

@property(nonatomic,strong)NSString*otherUserID;

2，在EaseMessageViewController.m中

- (void)_sendMessage:(EMMessage*)message；方法中增加消息扩展

NSUserDefaults*d = [NSUserDefaultsstandardUserDefaults];

NSMutableDictionary*dic = [NSMutableDictionarydictionaryWithDictionary:message.ext];

dic[@"otherUserId"] =self.otherUserID;

dic[@"otherUserPic"] =self.otherUserPic;

dic[@"otherUserNick"] =self.otherUserNick;

dic[@"userId"] = [dobjectForKey:@"userId"];

dic[@"userPic"] = [dobjectForKey:@"userPic"];

dic[@"userNick"] = [dobjectForKey:@"userNick"];

message.ext= dic;

3，更改聊天气泡的颜色（EaseMessageViewController.m中）

- (void)viewDidLoad ；方法中更改聊天气泡颜色

[[EaseBaseMessageCellappearance]setSendBubbleBackgroundImage:[[UIImageimageNamed:@"bubbleSen"]stretchableImageWithLeftCapWidth:5topCapHeight:35]];

4，隐藏输入框中的录音按钮（EaseChatToolbar.h中）

- (void)_setupSubviews；方法中注释掉

//change input type

UIButton*styleChangeButton = [[UIButtonalloc]init];

styleChangeButton.accessibilityIdentifier=@"style";

styleChangeButton.autoresizingMask=UIViewAutoresizingFlexibleTopMargin;

[styleChangeButtonsetImage:[UIImageeaseImageNamed:@"EaseUIResource.bundle/chatBar_record"]forState:UIControlStateNormal];

[styleChangeButtonsetImage:[UIImageeaseImageNamed:@"EaseUIResource.bundle/chatBar_keyboard"]forState:UIControlStateSelected];

[styleChangeButtonaddTarget:selfaction:@selector(styleButtonAction:)forControlEvents:UIControlEventTouchUpInside];

EaseChatToolbarItem*styleItem = [[EaseChatToolbarItemalloc]initWithButton:styleChangeButtonwithView:nil];

[selfsetInputViewLeftItems:@[styleItem]];   

5，修改消息列表中的头像圆角（EaseImageView.h中）

- (void)_setupSubviews；方法中

_imageView.layer.cornerRadius=20;//设置头像圆角 （cell 高度 为 60 减去上下间距20，然后除以2）
