Question

在Cards项目中，https://github.com/PaoloCuscela/Cards我下载了该应用程序并运行它，但CardPlayer Card遇到一个问题。加载视图时未加载。如果在应有卡片的白色区域中单击，它将弹出并显示。似乎未加载卡信息。

视图加载时

点击应插入卡的区域

这是调试器控制台所说的

有人知道怎么回事吗？

已解决将backgroundIV.frame.size.height = 300添加到了CardPlayer.swift的208个

由@Shadowsheep聊天提供

Answer 1

问题在CardPlayer.swift类上，特别是在207（backgroundIV.frame.size.height = originalFrame.height + ( isPresenting ? move/2 : 0 )）行下

当controller加载时，height的{{1}}被设置为backgroundIV。

添加此检查（在0行下）应该可以解决您的问题。

此错误

// 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
}

与用户定义的运行时属性相关，该属性设置为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.中不属于CardPlayer的视图（如果需要，可以将其删除）

CardPlayer卡未加载
