flix's Issues

Align all nodes/CollectionViewCells from bottom ?

HEy Dian,
Is there is built-in support that can align collectionview cells(providers) from bottom ?
(By default, when you add a new provider/cell, it will be added from top of the screen and following last provider/cell. My quest here is if there is a built-in support or easy way to achieve align from bottom: first cell go to bottom of the screen and second following that on top of it ? )

How does Flix handle scroll ?

TL;DR
How does Flix handle scroll activity ? or does it provide sth like didScroll, didEndScroll, etc. ?

More:
When I was trying to figure the above out, more things came to me:
I found that if I set collectionView to current viewcontroller where all cells are built for, then all cells are messed up, so guessing the delegate for either tableview/collectionview is set somewhere, but cant seem to find it.
The actual delegate be set to is: RxCocoa.RxCollectionViewDelegateProxy , any idea to port that to current view controller where we need to build nodes/cells ?

Add in Demo/Guide in main README showcasing how to dynamically add in new CellProvider

Often times in real app, there are async requests return after viewDidLoad, and we want to update UI upon that return. In this particular context of Flix, main README does not document how to dynamically add in new cellProvider, but it seems there are ways to achieve that with Flix. So it would be nice to add a new section for that.

@DianQK Wdyt ?

How can I extend SingleUITableViewCellProvider and UICollectionViewDataSource?

I want to add a collectionView in SingleUITableViewCellProvider.

RxSwift 5

It would be nice to support RxSwift 5.

XCode 10.2 Build Error

After updating to xcode 10.2 I'm receiving the following error and it prevents me from building

SingleCollectionViewProvider<Cell: UICollectionViewCell> Does not conform protocol UniqueAnimatableCollectionViewProvider - Swift compiler error segmentation fault 11

SingleCollectionViewProvider<Cell: UICollectionViewCell> Does not conform protocol "UniqueAnimatableCollectionViewProvider" in UniqueCustomCollectionViewProvider.swift - it used compile with no problem, any idea on why this is happening lately on 2.0.0 release ? @DianQK

Q&A

1. Can I make a UIViewController as Provider?
2. Should I know RxSwift, RxCocoa and RxDataSources?

依赖5个其它库

说实话,依赖一个库的框架都不敢用,哈哈,亲是北京的~~

Segmentation fault: 11 While emitting IR SIL function ...

Maybe you will find Segmentation fault: 11 While emitting IR SIL function ... error info when use AnimatableCollectionViewProvider. This look like Swift bug.

This issue will closed when this error go away.

This code will cause Segmentation fault: 11:

class TestRadioProvider<Option: Equatable & StringIdentifiableType>: AnimatableCollectionViewProvider {
    func configureCell(_ collectionView: UICollectionView, cell: RadioCollectionViewCell, indexPath: IndexPath, value: Value) {
    }
    func createValues() -> Observable<[Value]> {
        return Observable.empty()
    }
    typealias Cell = RadioCollectionViewCell
    typealias Value = Option
}

There are some workaround methods:

add createAnimatableNodes:

class TestRadioProvider<Option: Equatable & StringIdentifiableType>: AnimatableCollectionViewProvider {
    func configureCell(_ collectionView: UICollectionView, cell: RadioCollectionViewCell, indexPath: IndexPath, value: Value) {
    }
    func createValues() -> Observable<[Value]> {
        return Observable.empty()
    }
    typealias Cell = RadioCollectionViewCell
    typealias Value = Option
    func createAnimatableNodes() -> Observable<[IdentifiableNode]> {
        let providerIdentity = self._flix_identity
        return createValues()
            .map { $0.map { IdentifiableNode(providerIdentity: providerIdentity, valueNode: $0) } }
    }
}

or add a model to warp this Option:

struct SegmentationFault11Warp<Value: Equatable & StringIdentifiableType>: Equatable & StringIdentifiableType {
    var identity: String {
        return value.identity
    }
    let value: Value
}

class TestRadioProvider<Option: Equatable & StringIdentifiableType>: AnimatableCollectionViewProvider {
    func configureCell(_ collectionView: UICollectionView, cell: RadioCollectionViewCell, indexPath: IndexPath, value: Value) {
    }
    func createValues() -> Observable<[Value]> {
        return Observable.empty()
    }
    typealias Cell = RadioCollectionViewCell
    typealias Value = SegmentationFault11Warp<Option>
}

Why my `tap action` is not working?

I write the code in viewDidLoad function at my viewController:

let provider = WNFlixAddButtonProvider()
 provider.tap.subscribe(onNext: { _ in
        print("Ooops")
}).disposed(by: self.disposeBag)
tableView.flix.build([provider])

And WNFlixAddButtonProvider is just based on UniqueCustomTableViewProvider:

class WNFlixAddButtonProvider: UniqueCustomTableViewProvider {
        
    let addButton = UIButton().then {
        $0.backgroundColor = .red
        $0.setTitle("+ Work Experience", for: .normal)
        $0.setTitleColor(UIColor.blue, for: .normal)
        $0.titleLabel?.font = Specs.font.regular
    }
    
    override init() {
        super.init()
        
        contentView.addSubview(addButton)
        
        addButton.snp.makeConstraints { (make) in
            make.edges.equalToSuperview()
        }
    }
}

When I run the project, the UI look's perfect, but when I tap the addButton, it's not working.

I find some code at: Flix/Example/Example/LoginViewController.swift, the tap action works:

loginProvider.tap
            .withLatestFrom(isVerified).filter { $0 }
            .subscribe(onNext: { [weak self] _ in
                let alert = UIAlertController(title: "Success", message: nil, preferredStyle: .alert)
                alert.addAction(UIAlertAction(title: "OK", style: .default, handler: { (_) in
                    self?.navigationController?.popViewController(animated: true)
                }))
                self?.present(alert, animated: true, completion: nil)
            })
            .disposed(by: disposeBag)

Some code I miss?

I cannot understand why define the type of provider.sectionHeight is ((UITableView) -> CGFloat)?

I always use the following code
provider.sectionHeight = { _ in return 180 }
Why not define provider.sectionHeight is CGFloat? so I could write like this:
provider.sectionHeight = 180

pod search flix

not support cocoapods?

Typo in Flix/Flix/Builder/AnimatableCollectionViewBuilder.swift

Not a issue, but since I really like and use Flix heavily, want to point out a typo in the file and contribute a tiny :), cheers 👍

line 19

    let delegeteProxy = CollectionViewDelegateProxy()

guess you meant delegateProxy

After network request, tableView build the providers will offset some distance.

After network request in viewDidLoad function, I want to build the providers according to the network data.

// <NSThread: 0x170076e40>{number = 1, name = main}
let provider = WNFlixTitleTextFieldProvider(title: "Title", placeholder: "Placeholder")
self.tableView.flix.build([provider])

But if I just write this code in viewDidLoad function rather than after network request, it's good:

Add `GroupProvider`

• Add TableViewGroupProvider
• Add AnimatableTableViewGroupProvider
• Add CollectionViewGroupProvider
• Add AnimatableCollectionViewGroupProvider

Xcode 10 Swift 4.2 build failed

This is my Podfile:

But when I build the project, error happens:

Doesn't conform to protocol NSObjectProtocol

Thank you for your open source library, I have benefited a lot.

I've been using Objective-C for years, but I recently started using Swift in my work, so I do not know deep about it.

When I integrated a library (FSPagerView) I found that I needed to implement the ' NSObjectProtocol ' protocol, which I believe is the problem with this library interacting with Objective-C, and I want to ask if there is any suggestion? Thanks.

Is there a way to use `UniqueCommentTextProvider` in `SettingsViewController`

First, Great work!!
New to this, and have a quick question regarding the example provided:

In Do Not Disturb VC, there is this UniqueCommentTextProvider, how can that be used in SettingsViewController ? (it does not allow now as the former is a collection view cell, while the latter is mainly on a tableview) - so the question could also be: how to write a similar UniqueCommentTextProvider for collectionviewcell ?
Thanks ahead!!
