关于沙盒存储的基础使用

存储路径可用NSLog打印，然后回到左面可用快捷键 shift+command+g前往到存储的文件夹

读取沙盒中存储的数据

PS 存储数据还能用单例存储

NSUserDefaults *userDefault = [NSUserDefaults standardUserDefaults];

[userDefault setObject:@"123" forKey:@"account"];

[userDefault setObject:@"qaz" forKey:@"passWord"];

存储完后是在Preferences文件里面

获取单例存储的数据

NSString *account = [[NSUserDefaults standardUserDefaults] objectForKey:@"account"];

NSString *passWord = [[NSUserDefaults standardUserDefaults] objectForKey:@"passWord"];
