问题 In watchOS 2, there are no more shared keychains. If I want to send a keychain value from the iOS app to the Watch app, is it safe to send it via WCSession updateApplicationContext? 回答1: As per the Apple Security guideline:- Keychain Data Protection Many apps need to handle passwords and other short but sensitive bits of data, such as keys and login tokens. The iOS keychain provides a secure way to store these items. The keychain is implemented as a SQLite database stored on the file system.

How to share data using Watch Connectivity when working with Core Data

由 馋奶兔 提交于 2019-12-03 06:02:34
In my iOS application I use Core Data to store data and a fetch request to create an array of NSManagedObject s to display in a UITableView . On the Watch OS I check if WCSession is supported and active a session, then send the iOS application a message from the watchOS extension. When the iOS application receives the message from the watchOS it should send the array of Objects to the watchOS extension to display the data in the WKInterfaceTable , but I am unsure how to do this. Ultimately what I am trying to achieve is; How to share the array of Objects with the watchOS extension? If the user

How To Share Data with Watch OS 2 to display in WKInterfaceTable when working with CoreData

由 核能气质少年 提交于 2019-11-30 16:24:40
I am using WatchConnectivity to try to send data of type NSManagedObject called arrayOfOjects to the Watch. Each object has a string property called title . The InterfaceController on the Watch loads and displays and empty table - as intended because the array is empty, then when the user requests the data it is sent using the didReceiveMessage method on the phone. I am unsure how to add the dictionary array to the objectsArray to display in the WKInterfaceTable . Does anyone know how I can send the data to the watch to display in the table to make changes and sync them back with the phone ?
