NSUserDefaults 保存自己定义对象

项目里json返回的一个model须要保存下来，这个model是固定的没必须去创建表，想到了NSUserDefaults来存储，暂不考虑安全问题。

NSUserDefaults没法直接存储一个对象。在网上找到了方法。如今分享下。

首先要写一个对象，详细代码例如以下：

.h文件

@interface CustomSerModel : NSObject

@property(nonatomic,retain)NSString *m_deptId;//部门编号

@property(nonatomic,retain)NSString *m_sort_key;//姓名首字母，用于分组排序

@property(nonatomic,retain)NSString *m_imgUrl;//头像地址

@property(nonatomic,retain)NSString *m_imgKey;//头像文件的key

@property(nonatomic,retain)NSString *m_signature;//个性签名

@property(nonatomic,retain)NSString *m_name;//好友姓名

@property(nonatomic,retain)NSString *m_entUserId;//好友企业用户编号

@property(nonatomic,retain)NSString *m_entId;//好友企业编号

@property(nonatomic,retain)NSString *m_address;//地址

@property(nonatomic,retain)NSString *m_mobilePh;//手机号码

@property(nonatomic,retain)NSString *m_sex;//性别

@property(nonatomic,retain)NSString *m_shortPh;//集团短号

- (void)encodeWithCoder:(NSCoder *)aCoder;

- (id)initWithCoder:(NSCoder *)aDecoder;

+(BOOL) ParserJson:(NSString*)json withArray:(NSMutableArray *)array;

@end

.m文件

@implementation CustomSerModel

@synthesize m_deptId,m_sort_key,m_imgUrl,m_imgKey,m_signature,m_name,m_entUserId,m_entId,m_address,m_mobilePh,m_sex,m_shortPh;

-(void)dealloc

{

    [m_deptId release];

    [m_sort_key release];

    [m_imgUrl release];

    [m_imgKey release];

    [m_signature release];

    [m_name release];

    [m_entUserId release];

    [m_entId release];

    [m_address release];

    [m_mobilePh release];

    [m_sex release];

    [m_shortPh release];

    [super dealloc];

}

- (void) encodeWithCoder: (NSCoder *)coder

{

    [coder encodeObject:self.m_deptId forKey:@"DeptId"];

    [coder encodeObject:self.m_sort_key forKey:@"ImgKey"];

    [coder encodeObject:self.m_imgUrl forKey:@"ImgUrl"];

    [coder encodeObject:self.m_signature forKey:@"Signature"];

    [coder encodeObject:self.m_name forKey:@"Name"];

    [coder encodeObject:self.m_entId forKey:@"EntId"];

    [coder encodeObject:self.m_entUserId forKey:@"EntUserId"];

    [coder encodeObject:self.m_address forKey:@"Address"];

    [coder encodeObject:self.m_mobilePh forKey:@"MobilePh"];

    [coder encodeObject:self.m_sex forKey:@"Sex"];

    [coder encodeObject:self.m_shortPh forKey:@"ShortPh"];

}

- (id) initWithCoder: (NSCoder *) coder

{

    m_deptId = [[coder decodeObjectForKey:@"DeptId"]copy];

    m_imgKey = [[coder decodeObjectForKey:@"ImgKey"]copy];

    m_imgUrl = [[coder decodeObjectForKey:@"ImgUrl"]copy];

    m_signature = [[coder decodeObjectForKey:@"Signature"]copy];

    m_name = [[coder decodeObjectForKey:@"Name"]copy];

    m_entId = [[coder decodeObjectForKey:@"EntId"]copy];

    m_entUserId = [[coder decodeObjectForKey:@"EntUserId"]copy];

    m_address = [[coder decodeObjectForKey:@"Address"]copy];

    m_mobilePh = [[coder decodeObjectForKey:@"MobilePh"]copy];

    m_sex = [[coder decodeObjectForKey:@"Sex"]copy];

    m_shortPh = [[coder decodeObjectForKey:@"ShortPh"]copy];

    return self;

}

+(BOOL) ParserJson:(NSString*)json withArray:(NSMutableArray *)array

{

    //此处省略

    return TRUE;

}

@end

定义好对象后如今就是怎么使用了，保存方法：

 NSMutableArray *arr = [[NSMutableArray alloc]init];

            [CustomSerModel ParserJson:json withArray:arr];

            NSData *encodemenulist = [NSKeyedArchiver archivedDataWithRootObject:arr];

            NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];

            [defaults setObject:encodemenulist forKey:@"CustomList"];

获取方法：

NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];

    NSData *saveMenulistDaate = [defaults objectForKey:@"CustomList"];

    NSMutableArray *arr = (NSMutableArray *)[NSKeyedUnarchiver unarchiveObjectWithData:saveMenulistDaate];

完毕，感谢汗清提供的帮忙。
