如何在Xcode的UITests下的UIImagePickerController的某个索引处选择图像?

问题描述

当前，我通过以下方式访问照片库并拍照:

Currently I access photo gallery and pick up a photo the following way:

extension XCUIApplication {

    func pickPhotoFromImagePickerAtIndex(index: UInt) {

        tables.buttons["Moments"].tap()
        collectionViews["PhotosGridView"].tapCellAtIndex(index)
    }
}

使用示例:

photosCollectionView.tapCellAtIndex(0)
app.pickPhotoFromImagePickerAtIndex(5)

此方法有时会崩溃.这取决于画廊中的照片.

This method crashes sometimes. It depends on photos in gallery.

有什么方法可以更优雅，更有效地做到这一点?

Is there any way to do this in more elegant and effective way?

推荐答案

我认为，您需要点击的索引是从集合视图的底部开始计算的.如果是这样，那么您可以重新设计您的方法:

I assume, that index you need to tap is counted from the bottom of the collection view. If so, then you can redesign your method:

func pickPhotoFromImagePickerAtInvertedIndex(index: UInt) {

    tables.buttons["Camera Roll"].tap()
    let collectionView = collectionViews["PhotosGridView"]
    collectionView.cells.elementBoundByIndex(collectionView.cells.count - 1 - index).tap()
}
