To get an object from NSUserDefaults
you should use objectForKey:
, not valueForKey:
. valueForKey:
is used for key-value coding (KVC).

質問
I am encountering very strange problem.
I am saving users email and a encrypted key with [[NSUserDefaults standardUserDefaults] synchronize]
for login to my webserver with my ipad app. This method successfully saves key values and perfectly working on simulator and also perfectly working if I install app to my device with USB Cord.
But If I upload my .ipa file for enterprise users and they download and install the app [[NSUserDefaults standardUserDefaults] synchronize]
doesnt save email and key and returns null
.
[[NSUserDefaults standardUserDefaults] setInteger:userId forKey:@"user_id"];
[[NSUserDefaults standardUserDefaults] setObject:self.email.text forKey:@"email"];
[[NSUserDefaults standardUserDefaults] setObject:post_key forKey:@"key"];
[[NSUserDefaults standardUserDefaults] synchronize];
NSString *post_email = [[NSUserDefaults standardUserDefaults] valueForKey:@"email"];
NSString *post_key=[[NSUserDefaults standardUserDefaults] valueForKey:@"key"];
NSLog(@"post_email %@",post_email);
NSLog(@"post_key %@",post_key);
LOG ON Simulator and Device
post_email xxxxxx@gmail.com
post_key xxxxxxx
LOG ON ORGANIZER Device that installed .ipa file:
��May 17 13:31:19 xxxxxx[1590] <Warning>: post_email (null)
��May 17 13:31:19 xxxxxxx[1590] <Warning>: post_key (null)
Why is this happening? How can I fix this?
EDIT FOR FUTURE REFEFRENCES::::::
Even though rmaddy's answer is correct for null values exact problem was: ASIHTTPRequest begins but never ends
and the answer was: https://groups.google.com/forum/?fromgroups#!topic/asihttprequest/fw7PDcD2wKI
