问题
I am trying to build an iOS app that aids in Ecological Momentary Assessment of Patients. Basically it is a simple survey app that the patients need to take thrice a day.
I am new to iOS development and thus I cannot take some design decisions, I would really appreciate if some of you could look at these design decisions and let me know if it is possible in an iOS app.
- I want the patients to take these surveys thrice a day after their Breakfast, Lunch and Dinner. So I want my app to auto-start or at least pop-up a remainder for the user to start the survey app and fill the questionnaire. Is this possible?
- I want to assign a unique ID to each copy of the app, which the app should use to send the data to the central database which resides on the server. I don't want to bother the patients by giving a login form every time they start this app, or even the first time they start the app. So is this possible?
回答1:
- Can't auto start app, but you can use local notification to make the patient run your app
- If you don't need identify each patient, UUID is the unique ID for each device.
回答2:
That's not possible to start the app automatically on iOS, but you can show reminder in status bar. Use local notifications for this.
Regarding to unique ID, you can generate a random ID on the first launch of the app or just use device's UDID.
