Add the next element
To configure multiple elements, you can add the next element via the element of a Message object after creating the Message object. The following is the sample code for creating V2TIMTextElem and V2TIMCustomElem elements:

    V2TIMMessage *msg = [[V2TIMManager sharedInstance] createTextMessage:"text"];
    V2TIMCustomElem *customElem = [[V2TIMCustomElem alloc] init];
    customElem.data = ["自定义消息" dataUsingEncoding:NSUTF8StringEncoding];
    [msg.textElem appendElem:customElem];

Attention

• This API can be called only by elements of a Message object created via createMessage.
• This API can be used to add elements only of the V2TIMTextElem, V2TIMCustomElem, V2TIMFaceElem, and V2TIMLocationElem types.

Custom emoji index

1. The face message is defined by V2TIMFaceElem. The SDK does not provide face resource package. If the developer has face resource package, you can use index to mark a face, which can be customized by the user, or directly use data to store the expression binary information. All are defined by the user, and only transparent transmission is done inside the SDK.
2. Index and data only need to be passed in one, the SDK only transparently transmits these two data.
