I'm developing a library for iOS, named PhotoSubmitter, to facilitate the development of photo upload application.
PhotoSubmitter
This library can upload photo to Social Network Services and Cloud Services, there are lots of Services to support remaining.
And I want to the library to be plaggable.
I wish to know how to implement plaggable feature in Objective-C.
Plaggable means, when third-party service implementation for PhotoSubmitter is placed in the appropriate directory, like under plugins, the library automatically detect it.
If FacebookPhotoSubmitter.h/m placed in the plugins directory, code will be like,
[[PhotoSubmitterFactory sharedInstance] enableService:#"Facebook"];
And this code to be work properly with out including header "FacebookPhotoSubmitter.h" in both Client code and PhotoSubmitter library code.
If you know any of the similar implementation, please point the repository.
Any helps appreciated.
Thanks.
I think this post will be incredible helpful. (Mac OS X)
For iOS you can't dynamically load code on a AppStore app.

My app was rejected due to this ,Please help me to resolve this .This issue is new to me .
Guideline 2.5.1 - Performance - Software Requirements
Your app uses or references the following non-public APIs:
"_IOObjectRelease, IOServiceGetMatchingService, IOServiceMatching
The use of non-public APIs is not permitted on the App Store because it can lead to a poor user experience should these APIs change. Continuing to use or conceal non-public APIs in future submissions of this app may result in the termination of your Apple Developer account, as well as removal of all associated apps from the App Store.
Next Steps
If you are using third-party libraries, please update to the most recent version of those libraries. If you do not have access to the libraries' source, you may be able to search the compiled binary using the "strings" or "otool" command line tools. The "strings" tool can output a list of the methods that the library calls and "otool -ov" will output the Objective-C class structures and their defined methods. These tools can help you narrow down where the problematic code resides. You could also use the "nm" tool to verify if any third-party libraries are calling these APIs.
Resources
For information on the "nm" tool, please review the "nm tool" Xcode manual page. If there are no alternatives for providing the functionality your app requires, you can file an enhancement request.
Thanks in Advance !!!
I have gotten to the point where I can launch the barcode mock mode.
I am trying to figure out how I can start scanning test codes in development.
Or would an app that I am trying to test this on, need to have camera permissions on the app?
In that case, how do you overcome the use of the Camera Hardware on the PWA?
Or is there a way that I can scan QR-Codes using a different javascript API that would work in all cases?
Also, I had to move the camera and barcode service Javascript files into my Widget folder because when I was trying to reference them as you do on the instructions, the files wouldn't load.
Yes when you are in web it will mock the functionality because you're not on a device. There are HTML5 Camera API's see (https://www.html5rocks.com/en/tutorials/getusermedia/intro/)
You can use the BuildFire Previewer App (contact customer support if you havent downloaded it yet)
While you can take a copy of the services into your plugin it is risky. If we issue any updates or bug fixes you will not receive them. Also if it breaks compatibility at any time (rare but possible) your plugin stop working
I was trying to program a simple TODO app for Yosemite with sandboxing. Apple has its tutorials for the same but they are not very elaborate. I wanted to know sandbox APIs like sandbox_init() and APIs for console logs (heard sandboxed apps use some special APIs). Could someone please point me to some open source app with sandboxing on Yosemite, so that I could see the APIs that it is using.
You don't need to use sandbox_init() etc. in order to create a sandboxed app.
Roughly, you need to understand:
Use the APIs to find well known directories and don't assume that /Users/username/Documents is the Documents folder, for example.
The app has no access to user files and must gain access via NSOpenPanel.
If the app wants to retain access it has already gained then it needs to create and store bookmark URLs, which can be reloaded during a later invocation.
If the sandboxed app spawns a child process, then that child process needs it's own set of entitlements.
Once you understand that it's normally just a case of setting Use Sandbox in the app capabilities and you're off.
I've been searching all over the web and have found solutions to mounted device detection from within a Cocoa App using the NSWorkspace notification system. However this notification doesn't seem to be triggered when an Apple device is docked.
I specifically want my OSX App to detect docked iPads/iPhones, be able asses whether the iOS version of my App is installed and then synchronise files. I realise that the easiest way to do this is using iCloud, but I do not as yet have a developer membership with Apple and would like the option to be able to synchronise files without the internet.
An iTunes like system would be ideal. Any ideas.
Thanks in advance.
Apple don't provide any official APIs for doing what you ask.
Unofficially, you can try the stuff here: https://bitbucket.org/tristero/ipodaccessframework
You can definitely use it to determine whether a particular app is installed (by looking for a match for its bundle-id) and you can read/write files to/fro a particular apps document directory.
Disclaimer: this one is mine. There are definitely other libraries around that achieve similar results.
I am working on a Hybrid Application, targeting (for the moment) iOS. Does Worklight have a utility to handle application settings/preferences for iOS? I know how to write the native code to do this, but do not yet know how to gain access to the application settings from the JavaScript. Can anyone point me in the right direction or provide a working example?
In application-descriptor.xml, there is a worklightSettings flag you can set, however the settings page it creates is not user facing. That is, it is meant only for development time, or internal usage, and not production. It allows control of the server address that athe client connects to and change the web resources it will fetch.
So the answer is, no.
The mentioned settings page has set items in it that cannot be altered much (settings.bundle which does not allow much room for play. Maybe you could change it a bit, but doing so would void giving support to you if problems arise). I would recommend against doing so.
So this leaves you the option of creating this on your own. Maybe there is an existing Cordova plug-in that does something similar. Review these training modules of how to incorporate Cordova plug-ins to your application. Cordova bridges between JavaScript to native code, so it could be what you're looking for.
