解决方案

将json串转换成NSDictionary. 并将NSDictionary写入到.plist文件

- (void)writeToPlist：(NSDictionary *)map {
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *path = [paths objectAtIndex:0];
    NSString *plistPath = [path stringByAppendingPathComponent:@"user-data.plist"];
    [map writeToFile:plistPath atomically:YES];
}

NSString *json=yourjsonstring;
NSDictionary *dict=[NSJSONSerialization JSONWithObjectWithData:[json dataUsingEncoding:NSUTF8StringEncoding]  options:NSJSONReadingMutableContainers error:nil];
[self writeToPlist:dict];
