1、使用 NSUserDefaults存储自定义对象
NSArray *arr = [[NSArray alloc] initWithArray: json对象数组 ];
//使用NSKeyedArchiver 归档
NSData *ContactMulti = [NSKeyedArchiver archivedDataWithRootObject:arr];
NSUserDefaults *userDefault = [NSUserDefaults standardUserDefaults];
[userDefault setObject:ContactMulti forKey:@"ContactMulti"];
[userDefault synchronize];
2、获取NSUserDefaults存储的自定义对象
NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];
NSData *data = [userDefaults objectForKey:@"ContactMulti"];
self.currentChooseContacts = [NSMutableArray array];
////使用NSKeyedUnarchiver 反归档
self.currentChooseContacts = [NSKeyedUnarchiver unarchiveObjectWithData:data];
3、jsonmodel 对象
@interface ContactsModel : JSONModel
/// @brief 联系人Id
@property (strong,nonatomic) NSString *contactId;
/// @brief 部门Id
@property (strong,nonatomic) NSString *orgId;
/// @brief 联系人头像(图片名)
@property (strong,nonatomic) NSString *headImg;
/// @brief 联系人名字
@property (strong,nonatomic) NSString *usersName;
@end
