I'm trying to give a feature like google translate app where user can download multiple languages and see translations in those.
More specifically, I need to implement offline language translation. Like a user write some text and wants to translate it in some other language (Spanish or German) without internet.
Is there any way to do that? I'm not able to find anything about this. Please guide me through if someone knows about it.
Thanks.
I have not come across any solution that provides this functionality, although as google translate works, you do need to download required language pack one time. Then you can use it offline. Also language packs can be huge so you can definitely not keep all of them saved in your application at once.
In case this is your requirement, you can check out google ML Kit Translator for iOS. This is pretty neat along with the documentation.

I'am creating a new feature for my iOS app. After I publish the app I wants to show the new feature only for 50% of the users, so I can do some testing which version makes more orders. I have no idea how to do it without using some third parties like Optimizely.
Also is it possible to do this using Google Tag Manager(GTM).
So can someone please help me to figure this out.
Thank you very much for your time.:)
It’s hard to do it on your own, though not impossible of course: Optimizelys of the world are just programs. You’ll need to solve these problems:
Targeting: Some algorithm that will assign user session to either control or (one of) treatment(s). This has to be random, of course, or you may as well stop there.
Routing: Send sessios to the targeted experience.
Logging: You’ll need to intelligently log events from sessions as they traverse their targeted experience. These may be many, so be careful not to add latency to your app path. Your statistical analysis will be based on these.
Experience stability: how do you ensure (if you do) that a returning user sees the same experience he’s already seen.
Note as well, that Optimizely will only help you if all your changes are on the device and not on the server. If you need to instrument server changes as well, you’ll have to look into Sitespect or Variant.
I finally figured out how to do the A/B testing with 'Google Tag Manager'(GTM).
In GTM you can create a variable called 'Google Analytics Content Experiment'. With this variable you can select how many percentage of users going to see each Variation(your experiments). You can create up to 10 variations for single experiment.
GTM is so cool and powerful. GTM contains so many features that could save lot of time and I totally recommend it for anyone who is going to do A/B testing.
I'm new to iOS development and was wanting to know how to efficiently locate which kit, class to use to achieve certain things.
For example, I'm planning to build an app that heavily makes use of calendar events and I found that I should be looking at using something like eventkit to build upon but it's not clear for me within this kit which class to instantiate and which method to use in what order.
Can someone please direct me to a place where I can see some code examples of using a range of different kits?
I think you can learn things as you described from 'Reference'.
Two ways to check Apple Official References in Xcode. One is clicking the function name, parameter or those colorful keywords while you pushing the 'option'. The second way is using three fingers to touch those "keywords" slightly on the touchPad.
Or you can check many kits references by visiting iOS Developer Library (website). I'm also new to iOS Development, I wish things I said can help you.
Sorry for the generalized question...I have been hunting for a long time and haven't found anything I can use or easily adapt yet. I'd really appreciate any pointers!
I'm building a reference app that will contain several textbooks in plain-text format. I want the user to be able to perform a search, and get a table back with a list of results. I have a working prototype, but the search logic that I wrote isn't all that smart and it's been hell trying to make it better.
This is obviously a fairly common problem so I'm looking for a tool that I could adapt to the task. So far I've found Lucene (http://vafer.org/blog/20090107014544/) and Locayta (http://www.locayta.com/iOS-search-engine/locayta-search-mobile/)
Lucene appears to have been last updated for iOS 2...I don't even know if I'll be able to rework it myself. Maybe.
Locayta would probably work great, but a commercial license is $1,000 and I may not soon recoup that with this app, as it's a niche market.
Thanks!
We stumbled upon the same predicament where I work, and have yet to decide on a solution.
Locayta seems promising, but barring that, I've looked into SQLite's FTS3/FTS4 as well.
The only issue seemed the lack of a way to match partial words. It's easy to search for fields that contain whole words (eg. "paper" matches "printer paper", "paper punch", and "sketch paper"), or words that start with something (eg. "bi*" matches "binder", and "bicycle"), but there's no built in way to match a suffix.
If you don't require that functionality, FTS3/FTS4 might work.
I see you mentioned in the follow-up that your SQLite didn't recognize FTS3(), and I had the same issue at first.
Apparently it's not bundled into the iOS version by default, instead you have to download the SQLite3 amalgamation, and include it in the project manually. As found at is FTS available in the iOS build of SQLite?
Also note, the SQLITE_ENABLE_FTS3 variable is not enabled by default, you just have to add it to the configuration as detailed at http://www.sqlite.org/fts3.html#section_2
Hope this helps.
If you can translate plain C code to iOS Objective-C, then Apache Lucy (a loose "C" port of Lucene) might be worth a look.
I am just starting iOS development. I read some tutorials, watched stuff on iTunes U and wrote some sample code myself. Now I want to take the next step. I want to learn about best practices for iOS development in XCode.
Are there any well written and well organized iOS projects that one could take a look at?
(As I see it, iOS is not exactly the place for open source enthusiasts, however.)
Thanks
Mike.
I agree with several of the other answers that state that looking at many, many projects for mini-examples of what you want to do in your own app is the way to go.
However, you asked for an example of an app demonstrating best practices.
You could do worse than to read Matt Gallagher's blog, Cocoa with Love from beginning to end. However, the app example you asked for is right here.
Not only will it show a variety of techniques, some novel design and best-practices, but also he points out where he feels that he might have done something better.
It's a great read.
I would suggest the following process: (it worked for me)
Think of an advanced app. that you eventually want to be proficient enough to create.
Make a top-down problem-solving tree containing the necessary skills required to build your final app.
Use this tree to divide your final app. into 'sub apps'. Start at the bottom of the tree, find a tutorial specifically for that skill, and make a "Hello World" app. that uses that skill.
Keep progressing upwards, creating 'sub apps' as you go.
When you are finally ready to make your final app. (it will take a while), you will have a good handle on how iOS development works. It will also be a great test of your knowledge via direct application!
Getting the hang of iOS development can be tricky; it really does require a top-down approach, and every online resource I've found takes a linear one. The only way that I think a linear approach to learning iOS development would be manageable, is to take it one small task at a time.
As for specific resources, I always google "[what I want to do] iPhone SDK" and browse the tutorials and forum posts that come up.
Here are some open source iOS apps. However, they aren't very well documented and are also very advanced.
TKAWebView - A subclass of UIWebView that handles authentication and downloading.
Welcome to your Mac - An iOS app. to VNC into a PC/Mac and do some cool stuff.
InAppSettingsKit - A settings screen creator for your apps.
Good luck!
The people behind the Parse platform have made two complete projects.
For each project there is the complete source code, a tutorial and the resulting app is also available from the AppStore.
Anywall: https://parse.com/anywall
Anypic: https://parse.com/anypic
They both rely heavily on the Parse platform as the data source, but you still get a feel for an iOS project.
Molecules is a great open-source app that uses 3D OpenGL to render complex models of molecules.
Just keep coding my friend. You'll learn over a period of time. The best way to get dirty in a mud fight is to jump into it... Weird analogy but you get the point.
Maybe someday, we all will learn from you then !
Like you said there many and many source codes are available internet, but most are incomplete.
I found some Open source codes of REAL application currently available through Apple app store are given here
Free iPhone App Source Codes of real apps
and also, you can find many answers here on stackoverflow question - Are there any Open-source iPhone applications around?
You can download free IOS sample projects from http://devcodemarket.com
I realize this is an old thread but I've also been looking for good objective-c code examples recently and I just realized that TextEdit's source code is available at the Mac Developer Library webpage.
Also, here are some popular objective-c libraries that have caught my attention:
CocoaPods
AFNetworking.
you can also go through UICatalog from Developers Library and download the sample code. just google it and you will find a project containing all basics of iphone.
I don't think there is any perfect project that can demonstrate all the qualities of great code. Developers have stylistic preferences and may make mistakes. That said, you should look at a lot of different projects and try to look at the conventions used.
I'd suggest starting on GitHub. Besides for seeing code, you'll see what libraries are out there, which may help further your projects later on. Here's the Objective-C page on GitHub.
(Also, I (GitHub link) think you're wrong about iOS devs not being in favor open source. Yes, there's money to be made, but you can't sell a CSV paring library on the App Store as is.)
Have a look at https://github.com/mozilla/firefox-ios
That is Firefox for iOS, written in Swift.
Cocoacontrols has a wide range of controls written using Objective-C & Swift.
I believe these days, this is one of the most famous website for iOS Developers.
But, before you jump onto this, you have to learn Objective-C & Swift very well, so that you will understand how to use the controls in your app which makes your app smooth.
