我在应用程序商店中有这个应用程序，根据Crashalitics，它的％92-％95稳定。我为Android制作了类似的应用程序，其稳定性约为98％。我想要稳定起来 - 但我不知道如何。我在IOS版本中看到的所有错误都没有触及我的代码。
我看到随机错误，这些错误是不可重复的，当它们确实非常随机时。每次发生1-10次，但我列出了~~ 30种不同的项目。
该应用程序非常简单 - 一个主要是线性的故事板（一些跳转，但没有循环）。我使用的唯一不是Apple代码的项目是InAppSettingsKit，大多数应用程序只是显示一些项目的地图。该项目使用ARC，目前使用XCode6编译（但XCode5显示相同的症状）。
我怎样才能发现这些崩溃？这是IOS7-8的固有问题吗？我确实看到一些应用程序在我使用iPhone时关闭，而朋友告诉我IOS不稳定，但是......我只是认为我我做错了。
