IPhone应用程序视图转换变得急促

我有一个视图，其中包含使用原型单元格的UITableView。它包含一些我连接到interface builder中的子类UITableViewCell的标签

当我单击一行时，我已经在情节提要中创建了一个到详细视图的序列。该视图也可以通过另一个类的segue访问

我的表格和详图视图使用导航控制器

我的问题是，当我多次从表视图转换到细节视图并再次转换时，我注意到过了一段时间后，从细节视图转换回表视图开始变得不稳定。表格滚动也开始有点不平稳

我用的是ARC

如果有人能告诉我什么可能导致这种情况，或者我应该使用什么工具来调查，我将不胜感激

我会写下我的一些源代码以备不时之需。如果还有什么需要我提供的，请告诉我

表视图是从远程服务填充的，但是问题发生在表已经填充并且我不再调用该服务之后
