NSUserDefaults in iOS 8 and under iOS 8

问题

I know NSUserDefaults saves data in a app, so data is cleared after deleting app under iOS 8. but data persists after deleting app in iOS 8.

NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];

Below codes works in iOS 8 (data is cleared after deleting app)

NSUserDefaults *defaults = [[NSUserDefaults alloc] initWithSuiteName:@"group.com.AppCompany.Appname"];

Does this code works under iOS 8?

回答1:

If you are running your application in ios Simulator NSUserDefaults will not be cleared . it is the simulator bug .It work perfectly in ios device.
