# FastPdfKit



----



This repository contains the FastPdfKit iOS library with some sample projects.

 

FastPdfKit is a library that let you show pdf documents in iOS applications bypassing all performances and missing features problems related to QuickLook.



Side scrolling, search with highlighted results, preview and thumbnails, text extraction, overlay views, embedded multimedia, optimization for every device, single and double page are just some of countless features included in FastPdfKit.



For more information, see the [FastPdfKit website](http://fastpdfkit.com) and the [Support website](http://support.fastpdfkit.com).

All the other classes are public and can be customized or subclassed at will.



Every target can be compiled and recompiled for your needs.



## Usage guide



This guide is also available as [screencast number 4](http://fastpdfkit.com/tutorials).



* Clone the repository from [github](https://github.com/mobfarm/fastpdfkit) or just grab the compressed archive;

* Open your existing project in Xcode;

* Open the downloaded folder in the Finder and locate **FastPdfKit.embeddedframework**;

* Drag the framework on the Xcode workspace;

* Inherit the project options: select the Project an from info tab and configurations line choose **FastPdfKitFramework** from the drop down list;

* Open the framework's Resource folder and locate the **Snippets.txt** document;

* Copy in you controller interface these lines:



		#import 

		@class MFDocumentManager;

		-(IBAction)actionOpenPlainDocument:(id)sender;



* Copy in your controller implementation these other lines:



		-(IBAction)actionOpenPlainDocument:(id)sender{

		    /** Set document name */

		    NSString *documentName = @"Manual";



		    /** Get temporary directory to save thumbnails */

			NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);

    

		    /** Set thumbnails path */

		    NSString *thumbnailsPath = [[paths objectAtIndex:0] stringByAppendingPathComponent:[NSString stringWithFormat:@"%@",documentName]];

    

		    /** Get document from the App Bundle */

		    NSURL *documentUrl = [NSURL fileURLWithPath:[[NSBundle mainBundle]pathForResource:documentName ofType:@"pdf"]];

    

		    /** Instancing the documentManager */

			MFDocumentManager *documentManager = [[MFDocumentManager alloc]initWithFileUrl:documentUrl];



			/** Instancing the readerViewController */

		    ReaderViewController *pdfViewController = [[ReaderViewController alloc]initWithDocumentManager:documentManager];

    

		    /** Set resources folder on the manager */

		    documentManager.resourceFolder = thumbnailsPath;



		    /** Set document id for thumbnail generation */

		    pdfViewController.documentId = documentName;

    

			/** Present the pdf on screen in a modal view */

		    [self presentModalViewController:pdfViewController animated:YES]; 

    

		    /** Release the pdf controller*/

		    [pdfViewController release];

		}



* Choose a pdf from the finder and drop it in the project;

* Change the `documentName` to the corresponding name;

* Call the `actionOpenPlainDocument` method to open the document;

* Enjoy.

For more informations reagarding Extensions [git.io/fpke](git.io/fpke).



### Update 3.1.3 (December 30th, 2011)

* Reworked page metrics synchronization to reduce lag on slow pdfs (more to come).

* Paged scroll view attribute is accessible again in the MFDocumentViewController

    public interface.

* FPK annotations parsing can be disabled by setting MFDocumentViewController's

    fpkAnnotationsEnabled to NO. Use this if you experience frequent freezes while

    skimming the pages.

* You can add multiple MFDocumentViewControllerDelegates by calling MFDocumentViewController's

    addDocumentDelegate: (and removeDocumentDelegate:). Check the interface for 

    details



### Update 3.1.2 (December 16th, 2011)

* Non-unlocked password protected douments should no more crash the application.

* Cordinates for taps on the right page are now correct.

* Fixed a bug involving multibyte fonts compromising search, introduced with

    unicode normalization.

* Few memory leaks in ReaderViewController.

* Overlay views are enbaled on any license again.

* Newstand is disabled as default due to a memory leak in the download procedure.

* Variable number of preview image. Check MFDocumentViewController header.



### Update 3.1.1 (November 30th, 2011)

* View size of the reader is now appropriate for the screen configuration (status bar only).

* Added missing dismiss button in ReaderViewController on iPhone.



### Update 3.1 (November 30th, 2011)

* Reverted to optional tiled overlay view (used for search resulth highlight). This

    seems to have fixed most 'crashes' (app bein killed actually) while zooming

    onto a page.

* A few memory leaks inside the unicode normalization data structures have been 

    fixed.

* Different handling of document view controller dismissal. It is no more necessary

    to call -cleanup on the MFDocumentViewController before relasing it. Actual

    method implementation does nothing.

* Quite a few small memory leaks fixed.

* Faster page redrawn on page transition (goToPage, setPageMode, etc.).

* MFHomeListPdfs is now BookItemView, be careful if you used to subclass the former

    in your project.

* Fixed a few errors in Win ANSI and Mac OS Roman encoding. For example, the Unicode

    character 'LEFT SINGLE QUOTATION MARK' U+2018 will no more be replaced by

    other characters.

* Changed font cache management. If you still get problem with [] (notedef) caracter

    in the text extracted, the cache might be the issue. Set MFDocumentManager's

    fontCacheEnabled property to NO.

* Unicode sequences will now be handled as such and the lib will no try (and fail)

    to compose them to a single unicode codepoint (it is related to search and

    extraction of text).

* Lib will now attemp to compose multibyte characted to a single codepoint for

    search and extraction.

* Added support to 14 (-2) Adobe Standard Fonts. If you get page empty, blank

    pages at text extraction check the simulator log and if the font marked as

    uncompleted is named like one of the files in the FPKCore/standard14fonts

    folder add that font to your application bundle.

* Font cache re-enabled. This time seems to work as expected.

* Default zoom not being set fixed (again).

* Search and extraction will not crash when certain characters are found. Instead

    a .notdef (usually it looks like an empty rect) value with be appended to the

    text.

* Enhanced search and extraction with Unicode composition and decomposition.

* Added search match modes:

	* Return an array of `MFTextItem` representing the matches of teh search term on the page passed as arguments. It is a good choice running this method in a secondary thread.

 	* `FPKSearchMode` has the following values:

 	* `FPKSearchModeHard` - if you search for 'bèzier' it will match 'bèzier' only but not

 'bezier'. If you search for 'bezier' it will match 'bezier' only.

 	* `FPKSearchModeSoft` - if you search for term 'bèzier' it will match both 'bezier' and 'bèzier'. Same if you search for 'bezier'.

 	* `FPKSearchModeSmart` - if you search for term 'bezier', it will also match 'bèzier', but if you search for 'bèzier' it will match 'bèzier' only.

	* Ignore case is self explanatory.

	* Default parameters are `FPKSearchModeSmart` and `ignoreCase` to `YES`.



### Update 3.0 (November 4th, 2011)

* Internal changes of the view hierarchy to provide more flexibility and overlay transitions.

* Revamped `ReaderViewController` user interface.

* Better thumbnail scroll view and generation.

* Added support to video overlay control parameters in the uri.

* Search now works for terms of unitary length.

* Added a method to retrieve annotations from the document and provide them as overlays.

* Slightly changes to `MFDocumentViewControllerDelegate` callbacks.

* New activation method with key *FPKLicenseKey* from *Info.plist*: no need to pull to get the activated version.



### Update 2.1.3 (September 27th, 2011)



Disabled the 2.1.1 font cache due to an implementation oversight. Will be re-introduced as soon as it will behave as expected.



### Update 2.1.2 (September 21th, 2011)

* Cleaned up text search and extraction a little bit. More fixes incoming.



### Update 2.1.1 (September 15th, 2011)
