无法在捆绑 CocoaPods 中加载 NIB
Could not load NIB in bundle CocoaPods
我已经从 cocoapods 安装了 PSCarouselView 到我的项目中。当我尝试使用这个库时，我遇到了运行时错误。错误提示无法加载 nib 文件...
我检查了库，发现 nib 文件已正确注册。而且我还检查了目标成员资格并选中了复选框。然后我检查 podspec 文件，找不到任何关于该库的 podspec，然后我为该库创建了一个 pod 规范文件。使用下面的命令
pod spec create [PSCarouselView]https://github.com/DeveloperPans/PSCarouselView
然后我可以检查podspec文件并添加以下命令；
s.resources = "Resources/*.xib"
s.resource_bundles = {
'PSCarouselView' => [
'Pod/**/*.xib'
实际上，在我将此命令添加到 podspec 之前，xib 文件已复制到我的项目中。我只是拼命尝试...
并且xib文件用下面显示的代码注册；
[self registerNib:[UINib nibWithNibName:@"PSCarouselCollectionCell" bundle:nil] forCellWithReuseIdentifier:@"PSCarouselCollectionCell"];
标识符也定义正确；
所以现在我很绝望如何解决这个问题。
我在下面分享错误；

您需要包含 pod 的捆绑包。
例如在我的代码中（基于集合视图的货币符号选择器）：
public class BGSCurrencyPickerVC: UIViewController,UICollectionViewDelegate {
public override func viewDidLoad() {
super.viewDidLoad()
// Register cell classes
let podBundle = NSBundle(path: NSBundle(forClass: BGSCurrencyPickerVC.self).pathForResource("BLAMCurrencyPicker", ofType: "bundle")!)
self.collectionView!.registerNib( UINib(nibName: "BGSCurrencyPickerCVCell", bundle: podBundle), forCellWithReuseIdentifier: "BGSCurrencyPickerCVCell")
查看示例 Collection View based swift cocoapod
再举个例子，Currency Picker cocoapod
对于Swift 3:
let podBundle = Bundle(path: Bundle(for: BLAMPaymentCVView.self).path(forResource: "BLAMPayment", ofType: "bundle")!)
如果与您的 .xib 捆绑包（本例中为 YourView.xib）在 pods 捆绑包中，您可以通过这种方式在文件所有者 UIView 子类中检索捆绑包。
let bundle = Bundle(for: self.classForCoder)
然后实例化视图：
nib.instantiate(withOwner: self, options: nil)
let nib = UINib(nibName: "YourView", bundle: bundle)
如果您想在 pod 模块之外子类化以这种方式加载的 UIView，最好使用下面的内容，因为 'self.classForCoder' 将为您提供子类所在的包。
let bundle = Bundle(for: <FileOwnerUIViewSubclass>.classForCoder())
