    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.

) 

Will attempt to recover by breaking constraint 
<NSLayoutConstraint:0x7fcc2a6dfac0 V:[UIImageView:0x7fcc2a6e1010(63)]> 

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.

把你的UIImageView，的UILabel，UIButton的單一的UIView（說MAINVIEW）。現在，mainView約束將從xib視圖（superView）引導，尾隨，頂部底部。現在UIImageView，UILabel，UIButton的約束是根據您的要求w.r.t. MAINVIEW。

注意：儘可能少地限制UIComponents，但請注意滿足您的要求。喜歡這裏，給約束這樣的：

1. 的UIImage：頂部，底部，領先WRT MAINVIEW和寬度不變，或者你可以到容器水平給中心領導，高度，寬度。 UIButton：頂部，底部，尾部wrt mainView和常量寬度，或者您可以水平居中給容器，領先，高度，寬度。

2. UILabel：領先的後面和水平居中的容器是足夠的，但你也可以給高度。 UILabel可以根據您剛纔需要指定x和y座標的文本字體大小自動獲取高度和寬度。
