Store the image and songs in the application directory. This is best and easy way to handle. Try the following code. it will be help you.

//Store Image/Songs files to Application Directory
+(BOOL)writeToFile:(NSData *)data fileName:(NSString *)fileName {

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];

    // the path to write file
    NSString *appFile = [documentsDirectory stringByAppendingPathComponent:fileName];

        return [data writeToFile:appFile atomically:YES];
}
//Image/songs -  Retrieve from Application Directory
+(NSData *)readFromFile:(NSString *)fileName {

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *filePath = [documentsDirectory stringByAppendingPathComponent:fileName];

将MP3歌曲和图像存储到您的应用程序项目的resources文件夹中，并在sqlite数据库中提供引用（因为在sqlite数据库中保存大文件不是一个好习惯）

Answer 3

我建议您将所有大尺寸项目存储在设备磁盘上，即Documents目录，并将其物理路径存储在核心数据或sqlite中，或者至少存储在plist文件中，以便您可以根据需要方便地检索它们。
