今天遇到一個這樣的問題，在5s的模擬器上邊能運行，換成6的模擬器就出現了

A user can't fix an error like that under most circumstances.
FBSOpenApplicationErrorDomain
code =4 error on StackOverflow suggests it is an error from
cached data on the simulator (for programmers). Cleaning and restarting

What versions of products - what iOS, what devices, what XCode version?
When does it crash - does the app make it out of initialising?
If you don't know how to use breakpoints in XCode, learn. An excellent tutorial on debugging app crashes in detail is
英語不好的甚是看不懂啊，但是找到紅色這幾個關鍵詞，應該是對在模擬器上對他們進行清理和重置，試了下，問題解決了。。還是有問題多去Stack OverFlow上逛逛吧
