Question

I’ve created a ‘Settings’ model for my iPhone app. It only contains two properties and a class method for loading and one instancemethod for saving.

I load it as follows

+ (UserSettings *)getCurrent {     NSUserDefaults *userPrefs = [NSUserDefaults standardUserDefaults];     UserSettings *settings = [UserSettings new];     settings.username = [userPrefs stringForKey:kUserNameKey];     settings.password = [userPrefs stringForKey:kPasswordKey];     [userPrefs release];     return settings; } 

The problem that the handling with the NSUserDefault casts an exception;

-[NSCFArray objectForKey:]: unrecognized selector sent to instance 0x50b220

I have imported my header with the constants which are defined as follows;

#define kUserNameKey    @'Username' #define kPasswordKey    @'Password' 

(I am aware of keychain and am planning on changing to that later on, but want to solve the userdefaults)

try removing the [userPrefs release] since you never retained or alloced it
