We all love NSUserDefaults for saving vital app info from session to session, but sometimes it can be tedious remembering the exact syntax. Here are two methods I found in a an open source framework that I think are pretty spiffy.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | -(id)retrieveFromUserDefaults:(NSString *)key {
NSUserDefaults *standardUserDefaults = [NSUserDefaults standardUserDefaults];
if (standardUserDefaults) return [standardUserDefaults objectForKey:key];
return nil;
}
-(void)saveToUserDefaults:(id)object key:(NSString *)key {
NSUserDefaults *standardUserDefaults = [NSUserDefaults standardUserDefaults];
if (standardUserDefaults) {
[standardUserDefaults setObject:object forKey:key];
[standardUserDefaults synchronize];
}
}
