NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"https://api.douban.com/v2/book/search?tag=computer"]];
//将请求的url数据放到NSData对象中
NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
//IOS5自带解析类NSJSONSerialization从response中解析出数据放到字典中
NSDictionary *weatherDic = [NSJSONSerialization JSONObjectWithData:response options:NSJSONReadingMutableLeaves error:&error];
NSArray *localdata=[weatherDic objectForKey:@"books"];
