Preparation of integrated ring letter Prerequisites:

1. Register as a link developer Click to enter the ring letter

2. Create an app in the developer background to get key

3. Download the official SDK DEMO click to view

Integration SDK Steps:

1. Importing the SDK

2. Set project Properties

2.2 SDK Dependency Library has

Note: ( If you are using Xcode7, suffix tbd) < tips >

2.3 If there is a conflict with-OBJC in your project, you can add-force_load to resolve

The 2.4 SDK does not support Bitcode, setting No in Build settings→linking→enable Bitcode.

Compiling the project

After the above steps are finished, compile the project, if there is no error, congratulations, the Integration SDK success, you can proceed to the next step.

SDK Synchronous/Async methods differentiate:

In the SDK, most network-related operations provide a synchronous approach (note: The synchronization method blocks the main thread and requires the user to create an asynchronous thread execution; Async is the Async method)

Initializing the SDK

1. Introduce the relevant header file #import "EMSDK.h"

2. In the following method in the appdelegate of the project, call the SDK corresponding method:

The SDK interface parameters that are called are interpreted as follows:

1.AppKey: Differentiate app logo, developer registration and admin background

2.apnscertname:ios the name of the certificate in the push. Create and upload a push certificate

3. Ring Letter for the IM section provides APNS push function, if you want to use, please jump to APNs offline push

Registered:

1. The registration mode is divided into two types, open registration and authorized registration. Client registration is only possible if the registration is open.

2. Open registration is for testing purposes, the formal environment is not recommended to register a ring letter account, the authorization process should be your server through the rest API provided by the ring to register, and then save to your server or return to the client.

Landing:

Login: Invokes the operation of the SDK's login interface;

Automatic Login:

Automatic login: After the first login is successful, you do not need to call the login method again, and the SDK will log you in automatically the next time the app launches. And if you fail to log on automatically, you can also read the previous session information. Configure whether to log in automatically the automatic login property is turned off by default and requires that you set it after the login succeeds so that you do not need to call the ring login again the next time the app starts, and can get a list of sessions without a network.

Automatic login will be canceled in the following cases

1. The user invokes the SDK logout action;

2. The user changed the password on another device, causing the automatic login to fail on this device;

3. The user's account is deleted from the server side;

4. The user logs on from another device and kicks the user who is logged on to the current device.

Therefore, before you call the login method, you should first decide whether to set up automatic login, if set, you do not need to call

In the SDK, if an automatic login occurs, the following callback

reconnects

When the line is dropped, the IOS SDK will automatically re-connect and only need to listen for the re-connected callback, without any action.

Exit Login:

There are two types of exit logins: Active logout and passive sign-out.

Active Exit Login: Call the SDK exit interface;

Passive Exit Login: 1, the account is logged on another device to log on, 2, the login account is deleted from the server side.

Logout:yes: Whether to release device token binding, the SDK internal processing when the passive exit, do not need to call the Exit method

Passive Logout Login:

Callback Method Listener:

There are many more features, and the official website is very very clear!

Easeui User Guide

Easeui is a UI library that encapsulates the commonly used controls for IM functionality, fragment, and so on, designed to help developers quickly integrate the Sdkeaseui and demo GitHub:

Https://github.com/easemob/easeui;

https://github.com/easemob/sdkdemoapp3.0_android,3.0 code needs to switch to sdk3.0 branch

Note: because this is a UI library, subsequent changes are likely to continue, and the old and new versions will not be as completely compatible with the API as the IM SDK. (official website is prompted)

Code Import

Easeui Library code is open source, the download of the SDK package contains this library, the decompression path is/examples/easeui

Import in Eclipse:

1. First import the Easeui project into eclipse

2. Introduce Easeui as a library in its own project. Right click on the Add button in the bottom right corner of your project →android→ → Select Easeui→ok→ok

Import in Android Studio: Open your as Project →file→new→import module→ Select or enter the Easeui library path →next→next→finish

You may have the following errors when you finish importing:

Find the appropriate error place to change the swiperefreshlayout.setcolorschemeresources to Swiperefreshlayout.setcolorscheme,viewcompat.getx to new Viewcompat (). GetX, then build again, or increase the version number of the V4 package, such as compile ' com.android.support:support-v4:23.1.1 '.

Main fragment

1.EaseConversationList-Chat page, the main fragment

2.EaseContactListFragment-Contact Page
