XML属性列表(plist)归档

NSArray *arr1 = @[@"a",@"b",@"c"];
NSString *filePath = @"xxx.data";
// 存储
[arr1 writeToFile:filePath atomically:YES];
// 读取
NSArray *arr2 = [NSArray arrayWithContentsOfFile:filePath];

Preference(偏好设置)

NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults]
// 存储
[userDefaults setObject:@"chaselen" forKey:@"username"];
[userDefaults setBool:YES forKey:@"rememberPwd"];
// 读取
NSString *username = [userDefaults objectForKey:@"username"];
BOOL rememberPwd = [userDefaults BoolForKey:@"rememberPwd"];
