[chaosVoid]

In the single mode, selecting the second photo is crashing
Tag version: 1.9.9, 2.0.4
Xcode: 11.1, xcode10
iOS: 13.1.2, 12.0.1

Added: Appears when usedPrefetch = false. True is normal, but the style has changed.

Hi @chaosVoid
Can you show me the crash log? I can't reproduce that.

@chaosVoid
Sorry, I'm late
I can reproduce in Example Project
Please can you show me your configuration(TLPhotosPickerConfigure)?

e.g. )

@IBAction func pickerButtonTap() {
        let viewController = CustomPhotoPickerViewController()
        var configure = TLPhotosPickerConfigure()
        configure.numberOfColumn = 3
        configure.singleSelectedMode = true
        configure.usedPrefetch = false
        viewController.configure = configure
        self.present(viewController, animated: true, completion: nil)
    }

And if you use cocoapods, please can you try modify this function?
( in TLPhotosPickerViewController.swift )

private func findIndexAndReloadCells(phAsset: PHAsset) {
        if
            var index = self.focusedCollection?.fetchResult?.index(of: phAsset),
            index != NSNotFound
        {
            index += (getfocusedIndex() == 0 && self.configure.usedCameraButton) ? 1 : 0
            let numberOfItems = self.collectionView.numberOfItems(inSection: 0)
            if index < numberOfItems {
                self.collectionView.reloadItems(at: [IndexPath(row: index, section: 0)])
            }
        }
    }

@DangarOpenxcell
I think you using old version. please update pods.

[chaosVoid]

I modified cocoaPods and won't crash, but it shows an exception.
Multiple 1 selected displays will appear, not single selection

    var config = TLPhotosPickerConfigure()
    config.numberOfColumn = 4
    config.groupByFetch = .day
    config.selectedColor = kMainColor
    config.cancelTitle = "取消"
    config.doneTitle = "完成"
    config.tapHereToChange = "点击这里更换相册"
    config.customLocalizedTitle = ["Camera Roll": "相机胶卷"]
    config.emptyMessage = "没有相册"
    config.mediaType = .image
    config.maxSelectedAssets = maxCount
    config.usedPrefetch = false
    config.singleSelectedMode = maxCount == 1 ? true : false

working fine after configuring below the property
let viewController = TLPhotosPickerViewController()
viewController.delegate = self
viewController.modalPresentationStyle = .fullScreen
var configure = TLPhotosPickerConfigure()
configure.numberOfColumn = 4
configure.mediaType = .image
configure.usedPrefetch = true
configure.maxSelectedAssets = 1
configure.singleSelectedMode = true
viewController.configure = configure
self.present(viewController, animated: true, completion: nil)
thanks for support

[chaosVoid]

Sorry, there is a wrong place in the configuration.
UsedPrefetch = false on crash

@chaosVoid
I can reproduce crash at using your's configure options.
I've fixed that and pushed now. Release 2.0.6
