Create an iOS URL scheme to integrate Task Coach
Would it be possible to at implement a custom URL scheme? Some possible uses would be:
1) taskcoach:// - simply open Task Coach to the home screen
2) taskcoach://?cat=abc - open to tasks in category abc
3) taskcoach://?sync - opens the Sync screen
5) There are probably other potential locations - but these are the ones that come to mind right now
I could then use a timer-based tool like Workflow or Launcher to automatically pop-up directly to the Sync screen in Task Coach - or use IFTTT (or some other tool) to take E-Mail messages or texts and convert them to tasks, or have IFTTT add a task for tagged calendar entries, etc......
NOTE: I am not suggesting that you do the work of integrating with E-Mail and calendars - IFTTT and similar tools can already do that.....but you need the URL scheme (taskcoach://addTask?subject=......) for IFTTT to launch to insert the task.
Unfortunately, I don't have a Mac so I can't modify or suggest source code. I do know that the Apple Developers page at https://developer.apple.com/library/ios/documentation/iPhone/Conceptual/iPhoneOSProgrammingGuide/Inter-AppCommunication/Inter-AppCommunication.html has details on "Registering Custom URL Schemes"
