flutter_lc_im 0.0.1

A LeanClound IM flutter plugin project.

flutter_lc_im

简单封装LeanCloud的IM功能，目前处于研发阶段，只封装了iOS端.

Getting Started

第一步 info.plist加入以下配置

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
	<key>NSAllowsArbitraryLoads</key>
	<true/>
</dict>
</plist>

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<array>
	<string>fetch</string>
	<string>remote-notification</string>
</array>
</plist>

第二步 AppDelegate.m中加入以下代码：

#import <ChatKit/LCChatKit.h>
#import <UserNotifications/UserNotifications.h>

- (BOOL)application:(UIApplication *)application
    didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
  // Override point for customization after application launch.
    [GeneratedPluginRegistrant registerWithRegistry:self];

    [LCChatKit setAppId:@"xxxxx" appKey:@"xxxxxx"];
    // 启用未读消息
    
    [AVIMClient setUnreadNotificationEnabled:true];
    [AVIMClient setTimeoutIntervalInSeconds:20];
    //    //添加输入框底部插件，如需更换图标标题，可子类化，然后调用 `+registerSubclass`
    [LCCKInputViewPluginTakePhoto registerSubclass];
    [LCCKInputViewPluginPickImage registerSubclass];
    [LCCKInputViewPluginLocation registerSubclass];
    
  return [super application:application didFinishLaunchingWithOptions:launchOptions];
}

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
    [AVOSCloud handleRemoteNotificationsWithDeviceToken:deviceToken];
}

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
    if (application.applicationState == UIApplicationStateActive) {
    } else {

        [[LCChatKit sharedInstance] didReceiveRemoteNotification:userInfo];
    }
}

- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString *,id> *)options {
    return YES;
}

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
    return YES;
}


/**
 * Required for iOS 10+
 * 在前台收到推送内容, 执行的方法
 */
- (void)userNotificationCenter:(UNUserNotificationCenter *)center
       willPresentNotification:(UNNotification *)notification
         withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler {
    NSDictionary *userInfo = notification.request.content.userInfo;
    if([notification.request.trigger isKindOfClass:[UNPushNotificationTrigger class]]) {
        //TODO:处理远程推送内容
        NSLog(@"%@", userInfo);
    }
    // 需要执行这个方法，选择是否提醒用户，有 Badge、Sound、Alert 三种类型可以选择设置
    completionHandler(UNNotificationPresentationOptionAlert);
}

/*!
 * Required for iOS 7+
 */
- (void)application:(UIApplication *)application
didReceiveRemoteNotification:(NSDictionary *)userInfo
fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {
    //TODO:处理远程推送内容
    NSLog(@"%@", userInfo);
    // Must be called when finished
    completionHandler(UIBackgroundFetchResultNewData);
}

#pragma mark - 实现注册APNs失败接口（可选）
///=============================================================================
/// @name 实现注册APNs失败接口（可选）
///=============================================================================

/**
 * also used in iOS10
 */
- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error {
    NSLog(@"%s\n[无法注册远程提醒, 错误信息]\nline:%@\n-----\n%@\n\n", __func__, @(__LINE__), error);
}

第三步 Flutter项目中加入以下代码：

FlutterLcIm.pushToChatView("userId","peerId", "baseInfoUrl");

FlutterLcIm.pushToChatView中第一个参数userId指的是当前用户的ID，第二个参数peerId是聊天对象的ID，第三个参数baseInfoUrl指的是获取用户信息的接口，格式如下： http://www.example.com/im/users,接口内参数格式如下：

baseInfoUrl = http://www.example.com/im/users
user info url = http://www.example.com/im/users/1
user info url返回的数据如下:
{
    "success": true,
    "errors": "",
    "result": {
        "username": "vector",
        "avatar_url": "http://thirdqq.qlogo.cn/g?b=oidb&k=h22EA0NsicnjEqG4OEcqKyg&s=100",
        "user_id": 1
    }
}
