[LoveCorner]

可以设置限制的张数吗

通过代理方法去控制

func assetsPickerController(_ picker: CTAssetsPickerController, didSelect asset: PHAsset) {
        imageCount += 1
 }

func assetsPickerController(_ picker: CTAssetsPickerController, didDeselect asset: PHAsset) {
        imageCount -= 1
 }
 //是否可以选中
 func assetsPickerController(_ picker: CTAssetsPickerController, shouldSelect asset: PHAsset) -> Bool {
        if imageCount >= 3 {
                return false
            }
        return true
 }
