手动切一下 老的push,再切回来,就会出有了,我想是一个bug.
I've just created a Segue from a ViewController (which is embedded in a UINavigationController) to another ViewController. It seems like that the new Segue types do not create the UINavigationItem (which contains the title label) on Segue creation as the push Segue type did in iOS 7. I've noticed this fact because I couldn't enter any title for the "new" ViewController after I created the Segue. There is also no place where I can properly place a bar button item. I couldn't find anything regarding this fact in the Segue documentation so I was wondering if the UINavigationItem isn't automatically being created anymore. It doesn't even show up in the document outline. Does somebody know something about that? Maybe it's just a Xcode Beta 3 issue? Here is a picture of the segue in the attributes inspector: |

之前认为Apple 的iOS 设计的要比 Android 稳定,我错了吗?
下载的许多客户端程序/游戏程序,经常会Crash,是程序写的不好(内存泄漏?刚启动也会吗?)还是iOS本身的不稳定!!!
如果在Android手机中可以简单联接到ddms,就可以查看系统log,很容易看到程序为什么出错,在iPhone中如何得知呢?试试Organizer吧,分析一下Device logs,也许有用.
