如何在 iOS 中为 HTML 文件添加书签？

Question

我有一堆本地 HTML 文件，我想在应用程序中创建书签功能。 当用户按下书签按钮时，它将数据保存在核心数据中。 该怎么做？

Answer 1

书签功能通常只包括保存指向现有数据的链接。为什么需要 Core Data 来保存它？如果您有很多书签，那将是有意义的。在这一点上，这对我来说似乎有点矫枉过正。但是，您可以使用 MagicalRecord (https://github.com/magicalpanda/MagicalRecord) 来完成 CoreData 的繁重工作。

 // create a bookmark record, you can also add title, image, timestamp, etc...
 NSDictionary *bookmarkRecord = @{"url":"http://www.igraczech.com"};

 // prepare dictionary for all the bookmark records you want to save
 NSMutableDictionary *records = [NSMutableDictionary new];
 [records addObject:bookmarkRecord forKey:@"Bookmark title"];

 // this saves the 'records' dictionary (immutable by default), size limit is about a megabyte or two
 [[NSUserDefaults standardUserDefaults] setObject:records forKey:@"bookmarks"];
 [[NSUserDefaults standardUserDefaults] synchronize];

 // this loads bookmarks into mutable dictionary so you can add/edit/remove/save another one safely
 id savedBookmarks = [[NSUserDefaults standardUserDefaults] objectForKey:@"bookmarks"];

 // here the bookmarks are stored, you should use ivar/property instead of this example
 NSMutableDictionary *bookmarks = [NSMutableDictionary new];

 if (savedBookmarks)
 {
     bookmarks = [bookmarks addContentsFromDictionary:savedBookmarks];
 }
