this may sound real NOOB! I want to check if it's the second time the user enters my application, so to keep the run count I'm using NSUserDefaults
. I have implemented the following code in my rootViewController
's viewDidLoad
method:
NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];
NSLog(@"hello %ld", (long)[userDefaults integerForKey:@"runCount"]);
if ([userDefaults integerForKey:@"runCount"] != 1) {
//not the 2nd run
[userDefaults setInteger:1 forKey:@"runCount"];
NSLog(@"not 2nd run");
} else {
//second run or more
NSLog(@"2nd run");
}
[userDefaults synchronize];
everything works fine, but the problem is that when I uninstall(delete and re-install) the application according to here and here the data should be cleared, but it is not and after re-installing the app previous data is still showing up. I'm running my app on iOS simulator using xCode6-beta and targeting the application on iOS 8
I think this is due to a bug in the iOS8 Beta Simulator.
The expected behavior is that when the app is deleted, the NSUserDefaults for that app are deleted as well.
A quick and annoying solution for now is to click, iOS Simulator -> Reset Content and Settings.
Xcode 9.2 with Simulator 10 still presents this issue. Menu option is now Hardware .. Erase All Content and Settings
I submitted a bug report btw
