我正在使用SlideView Controller，主要是当应用程序通过dropbox进入（使用dropbox登录）时，它转到FirstViewController并且在Simulator中整个应用程序正常工作，但在设备进入FirstViewController时它甚至崩溃它显示了它的界面。
在FirstViewController中，它与slideViewController链接，而slideViewController具有tableview和slideview的属性，以便显示下一个控制器（slideViewController）..
我有一些slideViewController的代码。即使在FirstViewController中，应用程序也在viewdidload下，然后是slideViewController，但我已经尝试了很多但是在设备应用程序中崩溃了。
任何人都可以帮我解决这个问题吗
我在下面发布我的代码..

解释错误消息：
类中发生错误：Skirr方法：-[SlideViewController viewDidLoad]，错误是添加了一个nil对象。
查看该方法并找到将某些内容添加到数组中的位置。
