CardPlayer 卡未加载

【中文标题】CardPlayer 卡未加载

【英文标题】：CardPlayer Card not loading

【发布时间】：2019-02-28 07:21:58

【问题描述】：

在 Cards 项目中，https://github.com/PaoloCuscela/Cards 我下载了应用程序并运行它，但遇到了 CardPlayer Card 的一个问题。加载视图时不会加载它。 如果在卡片所在的白色区域单击，它会弹出并可见。似乎没有加载卡信息。

当视图加载时

当卡片应该加载的区域被点击时

这是调试器控制台所说的

有谁知道可能出了什么问题？

更新：卡片布局功能

已解决在 CardPlayer.swift 的 208 中添加了 backgroundIV.frame.size.height = 300

感谢@Shadowsheep 聊天

【参考方案1】：

问题出在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，backgroundIV 的height 设置为0。

添加此检查（在207 行下）应该可以解决您的问题。

// 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

改为此错误

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.

与设置为Main.storyboard 中不属于 CardPlayer 的视图的用户定义运行时属性相关（如果需要，可以将其删除）

【讨论】：

感谢您的帮助。我将检查添加到第 207 行，问题似乎仍然存在。

@user3233623 它不应该。我已经尝试并测试过了。也许我们的文件不同，我今天从 GitHub 签出了 Card 演示。你能更新你的答案，显示你把支票放在哪里吗？您还可以发布整个 CardPlayer 布局功能。

@user3233623 是的，行是 207，你必须在第一个 frame.size.height 设置后测试 backgroundIV.frame.size.height = originalFrame.height + ( isPresenting ? move/2 : 0 ) ;-)。我已经更新了我的答案。把支票放在这行下面backgroundIV.frame.size.height = originalFrame.height + ( isPresenting ? move/2 : 0 )

@user3233623 看到我的其他 cmets，你必须检查之后，而不是在此行之前backgroundIV.frame.size.height = originalFrame.height + ( isPresenting ? move/2 : 0 )
