Question

我正在做一个简单的可可pod，它是一个自定义的UICollectionView。但是我无法使用UICollectionViewCell的xib文件。我收到错误：由于未捕获的异常终止应用程序＆＃39; NSInternalInconsistencyException＆＃39;，原因：＆＃39;无法在捆绑中加载NIB：＆＃39; NSBundle（已加载）＆＃39;名称＆＃39; CWNumberedCollectionViewCell＆＃39;。

import UIKit
class CWNumberedCollectionViewCell: UICollectionViewCell {

    override func awakeFromNib() {
        super.awakeFromNib()
        // Initialization code
    }
}


import Foundation
import UIKit

public class CWCollectionViewNumbered: UICollectionView{

    let cellIdentifier = "CWCell"

    public init(frame: CGRect, layout: UICollectionViewFlowLayout, parent: UIView) {
        super.init(frame: frame, collectionViewLayout: layout)
        self.allowsMultipleSelection = true
        self.delegate = self
        self.dataSource = self
        self.register( UINib.init( nibName:"CWNumberedCollectionViewCell", bundle: nil), forCellWithReuseIdentifier: cellIdentifier)
        self.backgroundColor = UIColor.blue
    }

    required public init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
    }

    override public func selectItem(at indexPath: IndexPath?, animated: Bool, scrollPosition: UICollectionViewScrollPosition) {
        print("tapped")
    }
}

I have added the xib file to copy bundle resource.

xib不在您要查找的模块中。您必须精确xib所在的当前模块包，例如使用let bundle = Bundle(for: self)。否则，链接器将在主bundle中查找资源。

以下是我从xib文件加载图片的示例：

class func loadImage(imageSize: ImageSize) throws -> UIImage {
    let bundle = Bundle(for: self)
    let imageName = self.imageName(imageSize)
    guard let image = UIImage(named: imageName, in: bundle, compatibleWith: .none) else {
        throw LoadingIndicatorError.missingImage
    }
    return image
}

无法在捆绑中加载NIB。 Cocoa Pod项目
