如何在iOS中的核心数据中添加json解析数据？

这个我的数据解析代码解析完成后，将这些数据添加到核心数据中

- （void）DataRetireve {deatilinfoarray = [[NSMutableArray alloc] init]; NSURL * url = [NSURL URLWithString：@“http://sms.instatalkcommunications.com/apireq/GetSMSCategories?t=1&h=admin&param=1”]; ASIHTTPRequest * request = [ASIHTTPRequest requestWithURL：url]; [request setDelegate：self]; [请求startAsynchronous]; }

SBJsonParser *parser = [[SBJsonParser alloc] init] ;

NSMutableArray *jsondata = [parser objectWithString:responseString];
NSMutableArray *jsondata1 = [[NSMutableArray alloc]init];

for(int i=0;i<jsondata.count;i++)
{

    info *myinfo=[[info alloc]init];
    myinfo.Id=@"Id";
    myinfo.Name=@"Name";
    myinfo.IsActive=@"IsActive";

    [jsondata1 addObject:myinfo];
     NSLog(@"%@",responseString);

}

   for(int i=0;i<jsondata1.count;i++)
   {
   info *myinfo= [jsondata1 objectAtIndex:i];

   [jsondata1 addObject:myinfo];

    }

最简单的方法就是使用它 -

int yPossion = 50, xPossion = 10; int temp = 0;
UIScrollView *scrollView = [[UIScrollView alloc]initWithFrame:self.view.frame];
[self.view addSubview:scrollView];
for (int i = 0; i<50; i++){
    UIButton *aButton = [UIButton buttonWithType:UIButtonTypeCustom];
    [aButton setBackgroundColor:[UIColor blackColor]];
    [aButton setBackgroundImage:[UIImage imageNamed:@"icon-menu.png"] forState:UIControlStateNormal];

    [aButton setTitle:[NSString stringWithFormat:@" %d",i] forState:UIControlStateNormal];
    [aButton setFrame:CGRectMake(xPossion, yPossion, 100, 50)];

    [scrollView addSubview:aButton];
    xPossion += aButton.frame.size.width+15;
    temp++;
    if (temp==3) {
        yPossion = aButton.frame.origin.y+aButton.frame.size.height+15;
        temp = 0;
        xPossion = 10;
        [scrollView setContentSize:CGSizeMake(scrollView.frame.size.width, yPossion+50)];
    }
}

但如果你想使用autoLayout约束，那么你可以按照这个链接可能会帮助你。
