     上课，特别是在线下
     <code>
 207
 </code>
     （
     <code>
 backgroundIV.frame.size.height = originalFrame.height + ( isPresenting ? move/2 : 0 )
 </code>
    ）
  
  
    什么时候
     <code>
 controller
 </code>
     加载
     <code>
 height
 </code>
     的
     <code>
 backgroundIV
 </code>
     被设置为
     <code>
 0
 </code>
    。
  
  
    添加此检查（在线下
     <code>
 207
 </code>
    ）应该解决你的问题。
  
   <pre>
 <code>
 // Issue is here
let currentHeight = backgroundIV.frame.size.height // <-- new line to store current value
/* this is line #207 */ backgroundIV.frame.size.height = originalFrame.height + ( isPresenting ? move/2 : 0 ) // This is line 207

// This is the check
if backgroundIV.frame.size.height <= 0 {
 print ("heigh is 0")
 backgroundIV.frame.size.height = currentHeight
}

</code>
 </pre>
  
    而是这个错误
  
   <pre>
 <code>
 Failed to set (icon) user 
defined inspected property on (Cards.CardPlayer): [<Cards.CardPlayer 
0x15d7c6a0> setValue:forUndefinedKey:]: this class is not key value 
coding-compliant for the key icon.

</code>
 </pre>
  
    与用户定义运行时属性相关联设置到视图中
     <code>
 Main.storyboard
 </code>
     不属于CardPlayer（你可以删除它，如果你想）
