NSUserDefaults 保存自定义对象

项目里json返回的一个model需要保存下来，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，现在分享下。

首先要写一个对象，具体代码如下：

.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

 NSMutableArray *arr = [[NSMutableArray alloc]init];[CustomSerModel ParserJson:json withArray:arr];NSData *encodemenulist = [NSKeyedArchiver archivedDataWithRootObject:arr];NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];[defaults setObject:encodemenulist forKey:@"CustomList"];

NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];NSData *saveMenulistDaate = [defaults objectForKey:@"CustomList"];NSMutableArray *arr = (NSMutableArray *)[NSKeyedUnarchiver unarchiveObjectWithData:saveMenulistDaate];
