我已经检查了allow_url_fopen及其确定的问题.
所以我最近正在研究Swift/iOS开发,我在堆栈视图中调整按钮的大小有点麻烦,我有以下布局:
在垂直StackView中有两个TextField和一个按钮,StackView水平和垂直居中(有一点间距).它是左右边距的锚定宽度方式.
我想减小按钮的大小,因此它大约是StackView宽度的80%.
我试过的事情:
我在故事板视图中而不是在代码中执行所有这些操作,因为我试图了解界面.
我有一个很好的搜索,似乎找不到任何适用的答案,道歉,如果它看起来很基本,但认为这可能是有利的,因为任何其他新的Xcode/Swift遇到这个问题.
我有一个表格,我从一个非常大的CSV导入,有超过100列.我刚刚注意到他们在列名中导入了空格.
有没有办法重命名所有列并删除空格?

我希望能够转换/显示 AES256 非对称加密图像,即使它看起来是垃圾,我读过一些关于 SO 的内容,建议删除标头,然后重新附加它们,所以即使看起来很疯狂仍然显示它。
重点是我想看看是否可以对使用已知公钥加密的图像数据集执行图像分类。如果我有一张猫的图片,并使用完全相同的密钥对其进行加密,那么结果通常是可重现的,并产生在某种程度上与原始图像相同的图像。
请原谅缺少代码,我不想用我正在考虑的想法来污染讨论,以便从你们可爱的人们那里得到适当的批评——我想说我不是加密专家,因此我在这里寻求建议。
