我在viewdidload里面做了数据请求
并在数据请求的成功方法中调用了页面的初始化方法[self chartViewSubView];
在这个方法中初始化了5个TWRChartView，并添加到一个scrollview当中
然后调用[self myLoadLineChart]，将五组数据生成TWRLineChart，并loadLineChart
但是当程序第一次启动后进入到这个页面的时候，只加载了第一个chartview的内容，scrollview滚动的时候，第2-5页都是空的。退出这个页面再进入的时候就能够全部显示了。
现在我只能延迟0.5秒后再执行一遍[self myLoadLineChart]，并且让scrollview刷新，才能够在第一次进入的时候全部加载。
这是什么问题？求一个详细一点的解答
数据请求成功部分的代码
[Network networkPOSTRequestWithURL:WORKPLANER body:bodys pageUniquenessIdentifier:bodys result:^(id result) {
self.workDic = [[NSDictionary alloc]init];
self.workDic = [result objectForKey:@"output"];
[self scrollSubView];//加载scrollview
[self chartViewSubView];//加载5个TWRChartView
//[NSTimer scheduledTimerWithTimeInterval:0.5 target:self selector:@selector(myLoadLineChart) userInfo:nil repeats:NO]; //刷新方法，注释掉后只显示第一个图表
[self.HUD hideAnimated:YES];
}
