在多个情节提要板上使用高分

Question

I have two storyboards in my game: the home page and the game itself. When a user gets a high score in the game i save it as their high score. How can i then take that high score to display it on the homepage without linking the view controllers to the same code.

Answer 1

Save highscore anywhere in your project

[[NSUserDefaults standardUserDefaults] setInteger:score forKey:@"kHighscoreKey"];
[[NSUserDefaults standardUserDefaults] synchronize];

Retrieve highscore anywhere else in your project

NSUInteger highScore = [[NSUserDefaults standardUserDefaults] integerForKey:@"kHighscoreKey"];

Answer 2

If your do not find your score data important or sensitive use NSUserDefaults

First scene:

NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setInteger:yourHighScore forKey:@"HighScore"];

Second scene:

NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
yourHighScore = [defaults integerForKey:@"HighScore"]
