Question

Hi All I’m New to Xcode I’m trying to insert image from UITableView to database(sqlite3) in ios 5
i tried below code

-(void)addItemCUR
{

    if(addStmt == nil) {
        const char *sql = "insert into Table(C_Name, C_Image) Values(?,?)";
        if(sqlite3_prepare_v2(database, sql, -1, &addStmt, NULL) != SQLITE_OK)
            NSAssert1(0, @"Error while creating add statement. '%s'", sqlite3_errmsg(database));
    }

    sqlite3_bind_text(addStmt, 1, [C_Name UTF8String], -1, SQLITE_TRANSIENT);

    NSData *ImageData = [[NSData alloc] initWithData:UIImagePNGRepresentation(self.C_Image)];
    int returnValue = -1;
    if(self.C_Image != nil)
       returnValue =        sqlite3_bind_blob(addStmt, 3, [ImageData bytes], [ImageData length], NULL);
    else
        returnValue =         sqlite3_bind_blob(addStmt, 4, nil, -1, NULL);



    if(SQLITE_DONE != sqlite3_step(addStmt))
        NSAssert1(0, @"Error while inserting data. '%s'", sqlite3_errmsg(database));
    else
        //SQLite provides a method to get the last primary key inserted by using sqlite3_last_insert_rowid
        rowid = sqlite3_last_insert_rowid(database);

    //Reset the add statement.
    sqlite3_reset(addStmt);
}

I’m getting Error like

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFConstantString CGImage]: unrecognized selector sent to instance 0xb7c0'
*** First throw call stack:

Please any one help me to get through this thanks in advance.

Try to store the images in local document directory.Then store the image path in sqlite.Following code will help you.

NSData *imageData = UIImagePNGRepresentation(photo);//photo - your image
NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDir = [documentPaths objectAtIndex:0];
NSString *pngFilePath = [NSString stringWithFormat:@"%@/photo.png",documentsDir]; 
[imageData writeToFile:pngFilePath atomically:YES];

NSArray *sysPaths = NSSearchPathForDirectoriesInDomains( NSDocumentDirectory, NSUserDomainMask, YES );
NSString *docDirectory = [sysPaths objectAtIndex:0];
NSString *filePath = [NSString stringWithFormat:@"%@/photo.png", docDirectory];

sqlite3 *database;
@try 
{
    NSString *query = [NSString stringWithFormat:@"INSERT INTO Photos(PhotoPath) VALUES('%@')",filePath];
    NSString *databasePath;
    NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDir = [documentPaths objectAtIndex:0];
    databasePath = [documentsDir stringByAppendingPathComponent:@"GolfElite.sqlite"];
    if (sqlite3_open([databasePath UTF8String], &database) == SQLITE_OK)    
    {
        NSLog(@"DB opened...");
        sqlite3_exec(database, [query UTF8String], NULL, NULL, NULL);   
    }

}
@catch (NSException * e) 
{
    NSLog(@"Exception = %@", e);
}
@finally
{
    sqlite3_close(database);
}
NSLog(@"Photos inserted successfully..");
