uicollectionviewcell内的uiimage和标签之间的间距。细胞的动态高度

时间:2015-06-16 15:09:08

标签: ios swift uicollectionviewcell uicollectionviewlayout

我正在尝试让我的标签和图像动态地改变uicollectionviewcell的高度。如何根据获得的每张图像估算出细胞的正确高度?它期望宽度和高度,但我不想扭曲图像。

我正在关注这个cocoapod:https://github.com/ecerney/CollectionViewWaterfallLayout

或者是否有更好的方法来设置标签/文字?

目前标签和图像之间的间距未设置...

故事板内的单元格如下所示,UIImageView设置为Aspect Fill:

获取图像集的代码

lazy var imageSet: [UIImage] = {
    var _imageSet = [UIImage]()
    for x in 0...10{
        let array = [600,800,900]
        let array2 = [1000,1200,1400]
        let randomIndex = Int(arc4random_uniform(UInt32(array.count)))
        let randomIndex2 = Int(arc4random_uniform(UInt32(array2.count)))

        let urlString:String = String(format: "http://lorempixel.com/%@/%@/", String(array[randomIndex]),String(array2[randomIndex2]))
        let image = UIImage(data: NSData(contentsOfURL: NSURL(string: urlString)!)!)
        print(urlString)
        print("\(x)\n")
        _imageSet.append(image!)
    }
    return _imageSet
}()

设置每个单元格大小的代码......

func collectionView(collectionView: UICollectionView, layout: UICollectionViewLayout, sizeForItemAtIndexPath indexPath: NSIndexPath) -> CGSize {


    let thisLayout = layout as! CollectionViewWaterfallLayout


    var globalImage = imageSet[indexPath.row]

    var finalWith = globalImage.size.width
    var finalHeight = globalImage.size.height

    var newSize = CGSize(width: finalWith, height: finalHeight )

    return newSize
}
