YYHSERSViewController *siteViewController=[[YYHSERSViewController alloc] init];
siteViewController.site=site;
siteViewController.sta.sName=site.title;
siteViewController.sta.sState=self.pString;
siteViewController.sta.sCity=self.cString;
NSLog(@"query:%@%@%@",site.title,self.pString,self.cString);
[self.navigationController pushViewController:siteViewController animated:YES];
sta、site都是siteViewController的属性 为啥site传值成功,sta在siteViewController确实空值!
