我有一个带有 xib 的自定义单元格。在 xib 中，我只插入了 UIImageView。我通过 UICollectionViewDelegateFlowLayout 设置单元格大小，以便每行有 3 个单元格，并且一切似乎都正常。但是当我开始向 UIImageView 中插入图片时，单元格大小增加了好几倍，单元格变得巨大，也就是说，在插入图片之前，单元格显示正确。我不明白应该在单元格 xib 中为 uiimageview 设置哪些约束和设置。我尝试设置顶部、左侧、右侧、底部、方面适合和剪辑到边界，但它没有帮助。我究竟做错了什么？
MVP 架构。
我正在制作一个应用程序，允许您通过 instagram 登录，然后显示您帐户中的一些信息。
我了解我应该拥有一个个人资料模型（Instagram 上的页面个人资料）。
事实证明，我将有一个演示者和一个ProfileService用于加载数据的类。
也就是说
struct Profile，
protocol ProfileViewDelegate
class ProfilePresenter {
var pc: ProfileService
var pfd: ProfileViewDelegate
}
class ProfileService
我已经有两个屏幕：授权和配置文件显示。假设我还有几个屏幕，例如，显示订阅者列表。我是否还需要单独为其制作演示者等？我是否需要为每个屏幕、授权屏幕等设置演示者？
如果我误解了，你能建议一个近似的类结构吗？
我正在尝试将 pod 添加到我的项目中，但由于某种原因，在调用 pod install 命令后，它告诉我在项目目录中找不到 pod 文件，但屏幕截图显示它是。问题是什么
