NSUser Defaults

therealnosserman · 03-13-2010, 07:39 AM

Hey, I was wondering if there is a NSUser default to save the location of an image on your app. If so, please help me understand how to incorporate it into my application.

EXAMPLE: In pokemon video games they have a saving feature. This helps you continue your adventure the next time you play the game. I was wondering if you guys know how to basically re-create that feature in an iphone app using NSUser defaults or any other way.

Please help me.

Thanks,

Code:

NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
NSString *yourPosition = [prefs stringForKey:@"position"];
						
NSLog(@"Your position is: %@",yourPosition);

//To set a default
NSString *newPosition = @"here";
[prefs setObject: newPosition forKey:@"position"];

NSUserDefaults will accept BOOLs,Strings, FLOATs, and INTs I believe.

I just showed using string values, but in your case you may want to use a FLOAT type for each part of your position. Search NSUserDefaults for more info.
