我使用tableview来显示它，但由于有很多接口，我不知道何时重新加载数据。我已经重新加载了每个请求的数据。但这会导致屏幕溢出。我感谢使用gcd ，但效果不好。我需要你的帮助，谢谢。
我的应用程序有一些代码：
ASISafeRelease(_getMainPicRequest)
ASISafeRelease(_newsListRequest)
ASISafeRelease(_articleListRequest)
ASISafeRelease(getNewsCountReq)
ASISafeRelease(getResouceCountReq)
ASISafeRelease(getArticelCountReq)
ASISafeRelease(getActiveCountReq)
//the first request
NSMutableDictionary * getMainPic = [NSMutableDictionary dictionary];
_getMainPicRequest = [HttpRequsetFactory getRequestKeys:getMainPic subUrl:SUB_URL_GETMAINPIC userCommon:YES];
[_getMainPicRequest setDelegate:self];
[_getMainPicRequest setDidFinishSelector:@selector(finish:)];
[_getMainPicRequest setDidFailSelector:@selector(fail:)];
[_getMainPicRequest startAsynchronous];
//the secode request
NSMutableDictionary * dic = [NSMutableDictionary dictionary];
[dic setObject:@"1" forKey:@"typeId"];
[dic setObject:@(1) forKey:@"page"];
[dic setObject:@(1) forKey:@"pageSize"];
_newsListRequest = [HttpRequsetFactory getRequestKeys:dic subUrl:SUB_URL_NEWSLIST userCommon:YES];
[_newsListRequest setDelegate:self];
[_newsListRequest setDidFinishSelector:@selector(finish:)];
[_newsListRequest setDidFailSelector:@selector(fail:)];
[_newsListRequest startAsynchronous];// the third request
NSMutableDictionary * articleDic = [NSMutableDictionary dictionary];
[articleDic setObject:@"1" forKey:@"typeId"];
[articleDic setObject:@"0" forKey:@"isGroupArticle"];
[articleDic setObject:@"0" forKey:@"recvId"];
[articleDic setObject:@(1) forKey:@"pageSize"];
[articleDic setObject:@"0" forKey:@"sort"];
[articleDic setObject:@(1) forKey:@"page"];
_articleListRequest = [HttpRequsetFactory getRequestKeys:articleDic subUrl:SUB_URLARTICLELIST userCommon:YES];
[_articleListRequest setDelegate:self];
[_articleListRequest setDidFinishSelector:@selector(finish:)];
[_articleListRequest setDidFailSelector:@selector(fail:)];
[_articleListRequest startAsynchronous];
//the forth request
[self getnewscount];
//the fifth request
[self getresoucecount];
enter code here
//the sixth request
[self getarticelcount];
//the seventh request
[self getactivecount];
[self creatHUD:LOCALIZATION(@"is_loading")];
[HUD show:YES];
//request fail
- (void)fail:(ASIFormDataRequest *)request{
[HUD hide:YES];
NSLog(@"request fail");
}}`
//request suc
- (void)finish:(ASIFormDataRequest *)request{
NSString *response = [[NSString alloc] initWithData:request.responseData encoding:NSUTF8StringEncoding];
NSDictionary *dic = [response JSONValue];
//NSLog(@"---------dic = %@",dic);
if (request.responseStatusCode == 200 && [[NSString stringWithFormat:@"%@",[dic objectForKey:CKEY]]isEqualToString:SUC_CKEY])
{
NSDictionary * model = [dic[@"newslist"]lastObject];
[_newsArray addObject:model];
[_myTableView reloadData];
} {
if（request == _newsListRequest）{
NSDictionary * model = [dic[@"articlelist"]lastObject];
[_articleArray addObject:model];
[_myTableView reloadData];
} else if（request == _articleListRequest）// WelPicModel * welModel = [[WelPicModel alloc]initWithDic:dic];
// [_imageArray addObject:welModel];
_imageArray = [NSMutableArray arrayWithArray:[WelPicModel makeWelPicModels:[dic objectForKey:@"mainpic"]]]; else {
[HUD hide:YES];
[_myTableView reloadData];
}
}
