获取iPhone通话记录(需越狱)

越狱后的手机的数据库文件可以自由访问,通话记录通常保存在call_History.db这个文件中.只要读取这个文件,我们就能知道目前手机的通话记录了

下面这段代码检测手机是否能读取到Call_History.db

NSFileManager *fileManager = [NSFileManager defaultManager];
NSDirectoryEnumerator *dirnum = [[NSFileManager defaultManager] enumeratorAtPath: @"/private/"];
NSString *nextItem = [NSString string];
while( (nextItem = [dirnum nextObject])) {
    if ([[nextItem pathExtension] isEqualToString: @"db"] ||
        [[nextItem pathExtension] isEqualToString: @"sqlitedb"]) {
        if ([fileManager isReadableFileAtPath:nextItem]) {
            NSLog(@"%@", nextItem);
        }
    }
}

通常发现的文件位置为var/wireless/Library/CallHistory/call_history.db,ios3和4可能不同,具体看上面代码打印的结果.

下面这段代码可以读出数据库中的内容,具体怎样显示自己定制把.

- (void)readCallLogs
{
    if (_dataArray == nil) {
        _dataArray = [[NSMutableArray alloc] init];
    }
    [_dataArray removeAllObjects];
    NSFileManager *fileManager = [NSFileManager defaultManager];
    NSString *callHisoryDatabasePath = @"var/wireless/Library/CallHistory/call_history.db";
    BOOL callHistoryFileExist = FALSE;
    callHistoryFileExist = [fileManager fileExistsAtPath:callHisoryDatabasePath];
    [fileManager release];
    //NSMutableArray *callHistory = [[NSMutableArray alloc] init];
    
    if(callHistoryFileExist) {
        if ([fileManager isReadableFileAtPath:callHisoryDatabasePath]) {
            sqlite3 *database;
            if(sqlite3_open([callHisoryDatabasePath UTF8String], &database) == SQLITE_OK) {
                sqlite3_stmt *compiledStatement;
                NSString *sqlStatement = [NSString stringWithString:@"SELECT * FROM call;"];
                
                int errorCode = sqlite3_prepare_v2(database, [sqlStatement UTF8String], -1,
                                                   &compiledStatement, NULL);
                if( errorCode == SQLITE_OK) {
                    int count = 1;
                    
                    while(sqlite3_step(compiledStatement) == SQLITE_ROW) {
                        // Read the data from the result row
                        NSMutableDictionary *callHistoryItem = [[NSMutableDictionary alloc] init];
                        int numberOfColumns = sqlite3_column_count(compiledStatement);
                        NSString *data;
                        NSString *columnName;
                        
                        for (int i = 0; i < numberOfColumns; i++) {
                            columnName = [[NSString alloc] initWithUTF8String:
                                          (char *)sqlite3_column_name(compiledStatement, i)];
                            
                            data = [[NSString alloc] initWithUTF8String:
                                    (char *)sqlite3_column_text(compiledStatement, i)];
                            
                            
                                } 
                            [callHistoryItem setObject:data forKey:columnName];
                            
                            [columnName release];
                            [data release];
                        }
                        [_dataArray addObject:callHistoryItem];
                        [callHistoryItem release];
                        count++;
                    }
                }
                else {
                    NSLog(@"Failed to retrieve table");
                    NSLog(@"Error Code: %d", errorCode);
                }
                sqlite3_finalize(compiledStatement);
            }
        }
    } 
    NSLog(@"%@",_dataArray);
}

到此,你就可以读出所有的通话记录了.
