将int保存到内部存储器xcode iphone dev

Question

我有一个名为int的{​​{1}}，我希望将其保存到手机的内存中，这样即使游戏关闭并重新开启，这也是永远不会删除的高分，

有人可以建议一种方法吗？

Answer 1

使用NSUserDefaults。

保存：

int score = 12345;
[[NSUserDefaults standardUserDefaults] setObject:[NSNumber numberWithInt:score] forKey:@"HIGHSCORE"];

加载：

int score = [[[NSUserDefaults standardUserDefaults] objectForKey:@"HIGHSCORE"] integerValue];

Answer 2

您应该阅读NSUserDefaults

的Apple文档

请参阅NSUserDefaults和Preferences and Settings Programming Guide

[[NSUserDefaults standardUserDefaults] setInteger: score forKey: @"Score"]

Answer 3

在我看来，保存最佳分数的简便方法是将分数保存为字符串值，并在需要时将其记录回来。

//this example assume that high score is in text    
NSString *SaveHighScore = HighScore.text;
    NSUserDefaults *defaultsHighScore = [NSUserDefaults standardUserDefaults];
    [defaultsHighScore setObject:SaveHighScore forKey:@"savedHighScore"];
    [defaultsHighScore synchronize];

并召回

 NSUserDefaults *defaultsHighScore = [NSUserDefaults standardUserDefaults];
NSString *loadHighScore = [defaultsHighScore objectForKey:@"savedHighScore"];
[HighScore setText :loadHighScore];
