Swift 2.0 項目中利用中自定義行高 時遇到的問題？

---

swift2.0 項目中遇到的問題， 在計算cell行高的時候運用了自動計算行高的方法， 若是換成直接指定行高就不會有這樣的打印。

Unable to simultaneously satisfy constraints.

Probably at least one of the constraints in the following list is one you don't want. Try this: (1) look at each constraint and try to figure out which you don't expect; (2) find the code that added the unwanted constraint or constraints and fix it. (Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints) 

(

    "<NSLayoutConstraint:0x7fe51d969800 V:|-(0)-[WeiQianWeiBo.statuseTopView:0x7fe51d962700]   (Names: '|':UITableViewCellContentView:0x7fe51d90a1c0 )>",

    "<NSLayoutConstraint:0x7fe51d969a70 V:[WeiQianWeiBo.statuseTopView:0x7fe51d962700(53)]>",

    "<NSLayoutConstraint:0x7fe51d96c120 V:[WeiQianWeiBo.statuseTopView:0x7fe51d962700]-(8)-[UILabel:0x7fe51b5d6f60'All together ... Me and a...']>",

    "<NSLayoutConstraint:0x7fe51d96d660 V:[UILabel:0x7fe51b5d6f60'All together ... Me and a...']-(8)-[WeiQianWeiBo.StatusPictureView:0x7fe51b88fc00]>",

    "<NSLayoutConstraint:0x7fe51d96d730 V:[WeiQianWeiBo.StatusPictureView:0x7fe51b88fc00(120)]>",

    "<NSLayoutConstraint:0x7fe51d96dc80 V:[WeiQianWeiBo.StatusPictureView:0x7fe51b88fc00]-(8)-[WeiQianWeiBo.StatusBotttomView:0x7fe51b5e8eb0]>",

    "<NSLayoutConstraint:0x7fe51d96dd20 V:[WeiQianWeiBo.StatusBotttomView:0x7fe51b5e8eb0(44)]>",

    "<NSLayoutConstraint:0x7fe51d96cc40 WeiQianWeiBo.StatusBotttomView:0x7fe51b5e8eb0.bottom == UITableViewCellContentView:0x7fe51d90a1c0.bottom>",

    "<NSLayoutConstraint:0x7fe51d96ee20 'UIView-Encapsulated-Layout-Height' V:[UITableViewCellContentView:0x7fe51d90a1c0(175)]>"

)

Will attempt to recover by breaking constraint 

<NSLayoutConstraint:0x7fe51d96dc80 V:[WeiQianWeiBo.StatusPictureView:0x7fe51b88fc00]-(8)-[WeiQianWeiBo.StatusBotttomView:0x7fe51b5e8eb0]>

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.

The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful.

這個問題不報錯， 只是在程序運行那個的時候在控制檯打印的，尚未找到好的解決方法。若是有人知道，求指教！
