我利用

    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];

[self setShouldPlaySounds:[defaults boolForKey:@"play_sounds_preference"]];

for "Key" I used the key value entered in the xml editor (double click on Root.plist). I know you can build preferences with "Identifier" key and "DefaultValue" but I don t want the settings to be accesible in the setting app, I just want two dictuinaries with some strings for my custom settings.

What am I doing wrong? Why can t I get the value of the preferences?
Is it simpler to create my own config file? Implementing a serializer.

你们是否在任何地方确定价值? 你们看到的是哪些行为是关于应否宣布的?

如果你第一次执行,情况如何?

NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setBool:YES forKey:@"play_sounds_preference"];
BOOL result = [defaults synchronize]; // force immediate saving of defaults.
NSLog(@"[defaults synchronize] returned %d", result);
