某唄極速版，簡易紅包輔助的代碼實現

github下載項目源碼，內含app包。

主要代碼

//紅包消息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]?@"已搶":@"沒搶",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);
    
    NSString * tradeNumber = [content getTradeNumber];
    long amount = (long)[content getAmount];
    NSString * text = [content getText];
    
    NSLog(@"do--autoGrabRedpacket--(%@, %ld, %@, %@, %@, senderId:%lld)",tradeNumber,amount,text,[content getRedPacketType],[content isCollected]?@"已搶":@"沒搶", senderId);
    
    SLCtRedPacketChannel * channel = [%c(SLCtRedPacketChannel) GENERAL];
    
    agent = [%c(SLCtRedPacketAgent) getInstance];
    
    // arg0
    // arg1 是 紅包id
    // arg2 是 senderId
    [agent sendCollectRedPacketRequestWithSLHttpCallback:nil withNSString:tradeNumber withLong:senderId withSLCtRedPacketChannel:channel];
    NSLog(@"do--autoGrabRedpacket--finish");
}

複製代碼

• 每當羣內有紅包消息，會觸發 _TtC3Jst29JST_RedpacketMessageViewModel 類的 initWithSLCtMessage 方法，初始化一個紅包信息model。
• redpacketMessage 是一個全局變量，表明紅包信息model,用於保存當前的紅包信息。從 redpacketMessage 中能拿到屬性 senderId 和 tradeNumber，這兩個是搶紅包的必備參數。
• SLCtRedPacketAgent * agent; 是一個紅包代理，用於處理紅包的邏輯，這裏只須要調用 "[agent sendCollectRedPacketRequestWithSLHttpCallback:nil withNSString:tradeNumber withLong:senderId withSLCtRedPacketChannel:channel]" 可實現秒搶紅包。

使用

• 直接下載工程，手機鏈接電腦，使用Xcode在手機運行工程便可。
• 進入羣聊頁面，自動秒搶當前羣內紅包。
