如何在NSUserDefault中使用NSDictionary？

Question

我想知道如何在NSDictionary中使用NSUserDefault？我必须将用户的姓名，点数和时间存储到用户默认值NSDictionary和字典中。

Answer 1

NSDictionary *dict = [[NSDictionary alloc] init];

[[NSUserDefaults standardUserDefaults] setObject:dict forKey:@"dict"];

[[NSUserDefaults standardUserDefaults] synchronize];

在检索数据时，

dict = [[NSUserDefaults standardUserDefaults] objectForKey:@"dict"]; 

Answer 2

NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject:yourData forKey:@"yourKey"];
[defaults synchronize];

id yourData = [defaults objectForKey:@"yourKey"];
