Data persistence: Users' default setting and new setting

I am building a project at the moment, if users set the default time is 20 minutes in View Controller A and users need to use this time as a timer in Controller B. I understand the data can be passed by delegation or notification, etc. What I am try to approach this by saving users' selection in View Controller A and retrieve in Controller B. The approach include Core data, plist and NSUserdefault. Which one should I use in this case? Meanwhile, I am thinking the users' setting should be sync between iOS and Mac as well. Thanks in advance.

Solution

  • You can use NSUserDefaults. It is fine. But what do you mean by synching between iOS and Mac? Do you mean Handoff between devices??
