收到“kCTMessageReceivedNotification"時如何獲取消

how to get the message when receiving the quot;kCTMessageReceivedNotificationquot; notification on IOS5(收到“kCTMessageReceivedNotification時如何獲取消息?IOS5通知)
本文介紹了收到“kCTMessageReceivedNotification"時如何獲取消息?IOS5通知的處理方法,對大家解決問題具有一定的參考價值,需要的朋友們下面隨著小編來一起學習吧!

問題描述

限時送ChatGPT賬號..

使用 ios4.x 我可以在收到kCTMessageReceivedNotification"通知時使用下面的代碼來獲取消息

With ios4.x I can use code below to get the message when get the "kCTMessageReceivedNotification" notification

CTTelephonyCenterAddObserver( ct, NULL, callback,NULL,NULL, CFNotificationSuspensionBehaviorHold); 

if ([notifyname isEqualToString:@"kCTMessageReceivedNotification"])//receive message
    {

        NSDictionary *info = (NSDictionary *)userInfo;
        CFNumberRef msgID = (CFNumberRef)[info objectForKey:@"kCTMessageIdKey"];
        int result;
        CFNumberGetValue((CFNumberRef)msgID, kCFNumberSInt32Type, &result);   
        Class CTMessageCenter = NSClassFromString(@"CTMessageCenter");
        id mc = [CTMessageCenter sharedMessageCenter];
        id incMsg = [mc incomingMessageWithId: result];}

但是使用 ios5 我不能這樣做,因為 incMsg 是 nil,所以我該怎么做才能得到消息?

But with ios5 I can't do it as incMsg is nil,so what can i do to get the message?

謝謝

推薦答案

這是我發現的...

僅查看轉儲的私有 API,ChatKit.framework 似乎可以提供幫助.看一眼CKSMSService.h

Just looking at the dumped private APIs, it looks like ChatKit.framework could help. Take a look at CKSMSService.h

或 CKMadridService.hiMessage 消息.

or CKMadridService.h for iMessage messages.

我確實很快嘗試在 CKSMSService 中混合我自己的方法:

I did quickly attempt to swizzle my own method in, for a couple methods in CKSMSService:

- (void)_receivedMessage: (id)arg1 replace:(BOOL)arg2 replacedRecordIdentifier:(int)arg3 postInternalNotification:(BOOL)arg4;

- (void)_receivedMessage: (id)arg1 replace:(BOOL)arg2 postInternalNotification:(BOOL)arg3;

但在 iOS 5.0.1 上,我沒有看到其中任何一個被調用(也許是我的錯誤?).因此,我嘗試直接從 sqlite SMS 數據庫中獲取消息.注意...我沒有構建完整的應用程序來注冊通知.我假設您獲取 kCTMessageReceivedNotification 的代碼沒問題……它只是不再給您 SMS content 了.因此,如果您將以下代碼放入通知處理程序中,您應該能夠看到消息文本:

but on iOS 5.0.1 I didn't see either of those get called (maybe my error?). So, I tried to just get the message directly from the sqlite SMS database. Note ... I didn't build the full app, to register for notifications. I'm assuming your code to get the kCTMessageReceivedNotification is ok ... it just doesn't give you the SMS content anymore. So, if you put the following code in your notification handler, you should be able to see the message text:

- (NSString *) mostRecentSMS  { 
    NSString *text = @"";

    sqlite3 *database;
    if(sqlite3_open([@"/private/var/mobile/Library/SMS/sms.db" UTF8String], &database) == SQLITE_OK) {
        sqlite3_stmt *statement;

        // iOS 4 and 5 may require different SQL, as the .db format may change
        const char *sql4 = "SELECT text from message ORDER BY rowid DESC";  // TODO: different for iOS 4.* ???
        const char *sql5 = "SELECT text from message ORDER BY rowid DESC";

        NSString *osVersion =[[UIDevice currentDevice] systemVersion];         
        if([osVersion hasPrefix:@"5"]) {
            // iOS 5.* -> tested
            sqlite3_prepare_v2(database, sql5, -1, &statement, NULL);
        } else {
            // iOS != 5.* -> untested!!!
            sqlite3_prepare_v2(database, sql4, -1, &statement, NULL);
        }

        // Use the while loop if you want more than just the most recent message
        //while (sqlite3_step(statement) == SQLITE_ROW) {
        if (sqlite3_step(statement) == SQLITE_ROW) {
            char *content = (char *)sqlite3_column_text(statement, 0);
            text = [NSString stringWithCString: content encoding: NSUTF8StringEncoding];
            sqlite3_finalize(statement);
        }

        sqlite3_close(database);
    }
    return text;
}    

現在,請確保此應用已安裝在 /Applications/ 中.如果您只是構建這個應用程序,并使用 Xcode 正常安裝,由于應用程序沙盒,您將在打開 sqlite 數據庫時收到權限被拒絕錯誤.

Now, make sure this app is installed in /Applications/. If you just build this app, and install normally with Xcode, you'll get a permission denied error opening the sqlite database, because of app sandboxing.

我的代碼片段只是獲取最新的文本內容.這是一個對數據庫進行更多操作的示例.查看 QuerySMS 方法.

My code snippet just gets the most recent text content. Here's an example of doing a little more with the database. Look at the QuerySMS method.

另外,這里是 的關于數據庫格式的鏈接短信.d??b.你可以在那里找到你需要的其他東西.或者,只需將 sms.db 復制到您的計算機,然后使用類似 Firefox SQLiteManager 插件.祝你好運!

Also, here's a link on the database format of sms.db. You can find what else you need in there. Or, just copy the sms.db to your computer, and browse it with something like the Firefox SQLiteManager plugin. Good luck!
