主要代码

//红包消息Model
%hook _TtC3Jst29JST_RedpacketMessageViewModel

- (id)initWithSLCtMessage:(id)arg1
{
    %log;
    redpacketMessage = %orig;
    
    long long senderId = [redpacketMessage getSenderId];
    
    SLCfGiveRedPacketMessageContentImpl * content = [redpacketMessage getContent];// <SLCfGiveRedPacketMessageContentImpl: 0x17445e240>
    
    NSLog(@"do--initWithSLCtMessage--content= (%@)",content);
    
    NSString * tradeNumber = [content getTradeNumber];
    
    long amount = (long)[content getAmount];
    
    NSString * text = [content getText];
    
    NSLog(@"do--initWithSLCtMessage--(%@, %ld, %@, %@, %@, senderId:%lld)",tradeNumber,amount,text,[content getRedPacketType],[content isCollected]?@"已抢":@"没抢",senderId);
    
    [self autoGrabRedpacket:redpacketMessage];
    
    return redpacketMessage;
}

%new
-(void)autoGrabRedpacket:(_TtC3Jst29JST_RedpacketMessageViewModel *)redpacket
{
    
    long long senderId = [redpacket getSenderId];
    
    SLCfGiveRedPacketMessageContentImpl * content = [redpacket getContent];// <SLCfGiveRedPacketMessageContentImpl: 0x17445e240>
    
    NSLog(@"do--autoGrabRedpacket--content= (%@)",content);

    SLCtRedPacketChannel * channel = [%c(SLCtRedPacketChannel) GENERAL];
    
    agent = [%c(SLCtRedPacketAgent) getInstance];
    
    // arg0
    // arg1 是 红包id
    // arg2 是 senderId

复制代码

• 每当群内有红包消息，会触发 _TtC3Jst29JST_RedpacketMessageViewModel 类的 initWithSLCtMessage 方法，初始化一个红包信息model。
• redpacketMessage 是一个全局变量，表明红包信息model,用于保存当前的红包信息。从 redpacketMessage 中能拿到属性 senderId 和 tradeNumber，这两个是抢红包的必备参数。
• SLCtRedPacketAgent * agent; 是一个红包代理，用于处理红包的逻辑，这里只须要调用 "[agent sendCollectRedPacketRequestWithSLHttpCallback:nil withNSString:tradeNumber withLong:senderId withSLCtRedPacketChannel:channel]" 可实现秒抢红包。

使用

• 直接下载工程，手机链接电脑，使用Xcode在手机运行工程便可。
• 进入群聊页面，自动秒抢当前群内红包。
