如何在iphone中的sqlite數據庫中插入圖像

如何在數據庫中插入圖像，我試過，但沒有插入。查詢中的問題在哪裏？這是我的模型類.m文件：sqlite3_prepare_v2之後的文件中的代碼我的跟蹤未插入sqlite3_bind_blob它直接在sqlite3_prepare_v2之後。這裏有什麼問題，請幫助我。在這裏保存數據是錯誤的。在模型類我創建UIImage* Photo;，使協議和sys如何在iphone中的sqlite數據庫中插入圖像

+(void)SaveImagesToSql:(NSData *)imgDat :(int)getid 
{ 
    NSString *filePath = [BaseModal getDBPath]; 
    sqlite3 *database; 
    sqlite3_stmt *updStmt; 
    NSLog(@"%@",filePath); 
    if (sqlite3_open([filePath UTF8String], &database) == SQLITE_OK) 
    { 
     NSString* sqliteQuery = [NSString stringWithFormat:@"UPDATE INTO Peoples (Photo) VALUES (?) where PeopleId =%i",getid]; 

     if(sqlite3_prepare_v2(database, [sqliteQuery UTF8String] , -1, &updStmt, NULL) == SQLITE_OK) { 

      sqlite3_bind_blob(updStmt, 1, [imgDat bytes], [imgDat length], NULL); 

     } 
     sqlite3_finalize(updStmt); 
    } 
    sqlite3_close(database); 
}

這是我的view.m文件我是從這個頁面中選擇圖像，然後插入到源碼文件

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { 

    imageView.image = [info objectForKey:@"UIImagePickerControllerOriginalImage"]; 
    //UIImageWriteToSavedPhotosAlbum(imageView.image, self, nil, nil); 

    NSArray *sysPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask,YES); 
    NSString *docDirectory = [sysPaths objectAtIndex:0]; 
    NSString *filePath = [NSString stringWithFormat:@"%@", docDirectory]; 
    NSLog(@"thiss%@",filePath); 
    UIImage *image = [info objectForKey:@"UIImagePickerControllerOriginalImage"]; 

    if(picker.sourceType == UIImagePickerControllerSourceTypePhotoLibrary) {  
     UIImageWriteToSavedPhotosAlbum(image, self, @selector(image:didFinishSavingWithError:contextInfo:), nil); 
     [picker dismissModalViewControllerAnimated:YES]; 
     return; 
    } 


    [picker release]; 
    UIImage *image1 =imageView.image; 
    NSData *myData = UIImagePNGRepresentation(image1); 

    [PeopleModal SaveImagesToSql:myData :peopleid]; 

    //[self.parentViewController dismissModalViewControllerAnimated:YES]; 

    [picker dismissModalViewControllerAnimated:YES]; 



}

不要將數據存儲在文檔目錄中的database.ave圖像中，然後將該路徑保存到數據庫中... – Narayana 2012-02-28 09:40:12

你不應該插入的斑點在分貝，這將使你的分貝非常非常緩慢！

您應該將圖像保存在應用程序的文檔目錄中，並在數據庫中僅保存圖像的路徑。
