Answer 1

just replace this function to my code because you got wrong database path

- (void) SaveImagesToSql: (NSData*) imgData  {

    directoryPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    documentsDirectory = [directoryPaths objectAtIndex:0];
    NSString * databasePath = [[NSString alloc]initWithString:[documentsDirectory stringByAppendingPathComponent:@"informationdb.sql"]];

    const char* sqlite3Query = "INSERT INTO PICTURES (PHOTO) VALUES (?)";
    int openDatabaseResult = sqlite3_open_v2([databasePath UTF8String], &sqlite3DatabaseObject, SQLITE_OPEN_READWRITE , NULL);
    if (openDatabaseResult == SQLITE_OK) {
        int sqlite3Prepare = sqlite3_prepare_v2(sqlite3DatabaseObject, sqlite3Query, -1, &sqlite3Statement, NULL);
        if( sqlite3Prepare == SQLITE_OK ) {
            sqlite3_bind_blob(sqlite3Statement, 1, [imgData bytes], [imgData length], SQLITE_TRANSIENT);
            sqlite3_step(sqlite3Statement);
        }
        else
        {
            NSLog(@"Error is: %s", sqlite3_errmsg(sqlite3DatabaseObject));
        }
        sqlite3_finalize(sqlite3Statement);

    }
    else NSLog( @"Error is:  %s", sqlite3_errmsg(sqlite3DatabaseObject) );
    sqlite3_close(sqlite3DatabaseObject);
}

here this is database screenshot

Don't drag to database in your project.if any problem than tell me

Here How I do modify as per your use.

NSData *imageData = UIImagePNGRepresentation(imgView.image);
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);

NSString *documentsDirectory = [paths objectAtIndex:0];

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setTimeStyle: NSDateFormatterShortStyle];
dateFormatter.dateFormat = @"ddMMyyyyhhmmss_SSS_a";
NSString *currentTime = [dateFormatter stringFromDate: [NSDate date]];

NSString *imageName=[NSString stringWithFormat:@"Image_%@",currentTime];

NSString *saveFilePath =[NSString stringWithFormat:@"%@.%@",imageName,@"png"];  //Store saveFilePath string to your database

NSString *localFilePath1 = [documentsDirectory stringByAppendingPathComponent:saveFilePath];

[imageData writeToFile:localFilePath1 atomically:YES];

Hope it helps you.
