i m looking for a way to display PDFs on iOS - for sure i could use a webView but are there some other ways?
Maybe some frameworks (i did not find any), that offer some more features like "draw on pdf etc"
It depend on what you want free or fee. I see a lot framework. Also It write with Objective-C. But it's not problem because you can use it with Bridging-Header.
I have used to PDKFkit but it have fee.
I see this compare, I think you can reference it Compare framework pdf iOS
Maybe It library can be fit what you want: vfr/Reader

What's the difference between the Apple audio frameworks?
(5 answers)
Closed 2 years ago.
I want to use these Framework to play sound in my iOS app. Can you advise the pros and cons of AVFoundation or AudioToolbox?
You would have to read about the frameworks and see which one is suitable for your use-case.
You should start with this: https://developer.apple.com/audio/
These frameworks are not substitute to each other. They are built for covering various levels of interaction.
For example, if your use-case is covered by using AVPlayer or Media Player then you do not need to use other framework. In case, you need something more out of the system u may consider other lower level frameworks.

how do i create and use custom vocabulary with sirikit?
(1 answer)
Closed 4 years ago.
I have some troubles to add custom vocabulary to Siri.
I have implemented Siri in my app and it works well with classical commands. However, I tried to add a custom phrase and it doesn't recognized it.
I tried the two ways described in "https://developer.apple.com/library/content/documentation/Intents/Conceptual/SiriIntegrationGuide/SpecifyingCustomVocabulary.html#//apple_ref/doc/uid/TP40016875-CH6-SW1" and followed all the steps.
Do you have any other tips or explanations ? Or could you tell me how I can debug this because I have no clue of what happening, if my AppIntentVocabulary.plist is taken into account or not for exemple.
Answer https://stackoverflow.com/a/48861352/1351327.
A lot of people faced this problem like me in the past.
We should wait Apple to add new intent domains. Open radar has so many requests for that.

What programming languages can one use to develop iPhone, iPod Touch and iPad (iOs) applications?
I have a load of fairly simple scientific programs that I converted from Basic to C. I would like to put them onto the Apple App Store, and was just wondering if it is necessary to convert them to Obj-C first, or will the C code be OK as a start?
They are simple 'get user input', 'do some logic checks', 'do the calcs', 'output result' type progs.
Thanks for any help.
Objective-C has a fully functioning C underneath, and you can write pure C code and have it working.
However, i doubt you would be able to release a command-line application to App Store. You would have to create a user interface in Xcode, and that would definitely introduce Objective-C to your program. With that said, as long as you connect your program variables (outlets) to controls on the UI, and link UI buttons back to the program's functions (actions/methods), the main processing body of your function could be a copy of your C code.

How to display a PDF in Objective-C? [closed]
(3 answers)
Closed 9 years ago.
I need to open some PDF files from my App and need some advices.
These files will be on my server and I would open them using a UIWebView.
Do you think it is a good idea or should I do somehow different?
Googling I found something about PDF Kit! Is it better or worst? And why?
In my experience UIWebView is fine for small files without many images.
If a PDF contains many pages or large colorful images then UIWebView may be not very fast to open it. And memory consumption might be high.
In the latter case you might want to use some third-party component or implement your own class. See Fast and Lean PDF Viewer for iPhone / iPad / iOs - tips and hints? for some useful tips.
Can anyone help with combining two pdf's together on an iPad? I dont know where to start.
I have an app that contains a lot of single page pdf's and I want to be able to allow the user to merge them together for printing and emailing if they wish.
I have looked at the various CGPDF classes but dont know where to begin.
I am sorry that I don't have an answer for your exact question, but Fast and Lean PDF Viewer for iPhone / iPad / iOs - tips and hints? is an excellent place to start. When I first started with all of this I used the iText library from Java to see what was actually going on behind the scenes with properties etc (since all the iOS CGPDF classes are Opaque).
