NSDictionary show null after converted

Question

NSString *profilestring = [self.userDefaults objectForKey:@"profilestrings"];
NSDictionary *dicProfile = [profilestring propertyListFromStringsFileFormat];
NSLog(@"--->>%@",profilestring);
NSLog(@">>%@",dicProfile);

self.userDefaults is NSUserDefaults, and NSLog(@"--->>%@",profilestring); prints a string, such as

{
    useraddtime = 1401444211;
    userage = 11;
    usernickname = XJD;
    usersex = 1;
    userstatus = 1;
}

but NSLog(@">>%@",dicProfile); prints (null), can you help me?

What are you trying to accomplish with the statement: `NSDictionary *dicProfile = [profilestring propertyListFromStringsFileFormat];`? — zaph, May 31 '14 at 12:38
@DMusic Your string i.e profilestring is not in .strings file format — Rohan Bhale, May 31 '14 at 12:43
@DMusic use propertyList instead of propertyListFromStringsFileFormat method on profilestring — Rohan Bhale, May 31 '14 at 12:54

Apples documentation says the keys and values themselves are always strings enclosed in straight quotation marks. Your keys and values are not enclosed in quotation marks. The string i.e profilestring should look like this

{
"useraddtime" = "1401444211";
"userage" = "11";
"usernickname" = "XJD";
"usersex" = "1";
"userstatus" = "1";

}

I doubt that the OP really wants ".strings file format", probably wants "plist" format. – zaph May 31 '14 at 12:46
@Zaph The method propertyListFromStringsFileFormat requires .string file formatted string – Rohan Bhale May 31 '14 at 12:48
Not really, plist format supports objects other than strings. – zaph May 31 '14 at 12:50
@Zaph for plist formatted string you need to use the method propertyList – Rohan Bhale May 31 '14 at 12:53

It looks like your [self.userDefaults objectForKey:@"profilestrings"] is actually a NSDictionary so you could do something like

NSDictionary *dicProfile = [NSDictionary dictionaryWithDictionary:[self.userDefaults objectForKey:@"profilestrings"]];
