|
||||
|
||||
There are many ways you can contribute! :heart:
|
||||
|
||||
### Bug Reports and Fixes :bug:
|
||||
- If you find a bug, please search for it in the [Issues](https://github.com/slackhq/PanModal/issues), and if it isn't already tracked,
|
||||
[create a new issue](https://github.com/slackhq/PanModal/issues/new). Fill out the "Bug Report" section of the issue template. Even if an Issue is closed, feel free to comment and add details, it will still
|
||||
be reviewed.
|
||||
- Issues that have already been identified as a bug (note: able to reproduce) will be labelled `bug`.
|
||||
- If you'd like to submit a fix for a bug, [send a Pull Request](#creating_a_pull_request) and mention the Issue number.
|
||||
- Include tests that isolate the bug and verifies that it was fixed.
|
||||
|
||||
### New Features :bulb:
|
||||
- If you'd like to add new functionality to this project, describe the problem you want to solve in a [new Issue](https://github.com/slackhq/PanModal/issues/new).
|
||||
- Issues that have been identified as a feature request will be labelled `enhancement`.
|
||||
- If you'd like to implement the new feature, please wait for feedback from the project
|
||||
maintainers before spending too much time writing the code. In some cases, `enhancement`s may
|
||||
not align well with the project objectives at the time.
|
||||
|
||||
### Tests :mag:, Documentation :books:, Miscellaneous :sparkles:
|
||||
- If you'd like to improve the tests, you want to make the documentation clearer, you have an
|
||||
alternative implementation of something that may have advantages over the way its currently
|
||||
done, or you have any other change, we would be happy to hear about it!
|
||||
- If its a trivial change, go ahead and [send a Pull Request](#creating_a_pull_request) with the changes you have in mind.
|
||||
- If not, [open an Issue](https://github.com/slackhq/PanModal/issues/new) to discuss the idea first.
|
||||
|
||||
If you're new to our project and looking for some way to make your first contribution, look for
|
||||
Issues labelled `good first contribution`.
|
||||
|
||||
## Requirements
|
||||
|
||||
For your contribution to be accepted:
|
||||
|
||||
- [x] You must have signed the [Contributor License Agreement (CLA)](https://cla-assistant.io/PanModal).
|
||||
- [x] The test suite must be complete and pass.
|
||||
- [x] The changes must be approved by code review.
|
||||
- [x] Commits should be atomic and messages must be descriptive. Related issues should be mentioned by Issue number.
|
||||
|
||||
If the contribution doesn't meet the above criteria, you may fail our automated checks or a maintainer will discuss it with you. You can continue to improve a Pull Request by adding commits to the branch from which the PR was created.
|
||||
|
||||
[Interested in knowing more about about pull requests at Slack?](https://slack.engineering/on-empathy-pull-requests-979e4257d158#.awxtvmb2z)
|
||||
|
||||
## Creating a Pull Request
|
||||
|
||||
1. :fork_and_knife: Fork the repository on GitHub.
|
||||
2. :runner: Clone/fetch your fork to your local development machine. It's a good idea to run the tests just
|
||||
to make sure everything is in order.
|
||||
3. :herb: Create a new branch and check it out.
|
||||
4. :crystal_ball: Make your changes and commit them locally. Magic happens here!
|
||||
5. :arrow_heading_up: Push your new branch to your fork. (e.g. `git push username fix-issue-16`).
|
||||
6. :inbox_tray: Open a Pull Request on github.com from your new branch on your fork to `master` in this
|
||||
repository.

## Features
|
||||
|
||||
* Supports any subclass of `UIViewController`
|
||||
* Seamless transition between modal and content
|
||||
* Maintains 60 fps performance
|
||||
|
||||
## Compatibility
|
||||
|
||||
PanModal requires **iOS 10+** and is compatible with **Swift 4.2** projects.
|
||||
|
||||
## Installation
|
||||
|
||||
* <a href="https://guides.cocoapods.org/using/using-cocoapods.html" target="_blank">CocoaPods</a>:
|
||||
|
||||
```ruby
|
||||
pod 'PanModal'
|
||||
```
|
||||
|
||||
* <a href="https://github.com/Carthage/Carthage" target="_blank">Carthage</a>:
|
||||
|
||||
```ruby
|
||||
github "slack/PanModal"
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
PanModal was designed to be used effortlessly. Simply call `presentPanModal` in the same way you would expect to present a `UIViewController`
|
||||
|
||||
```swift
|
||||
viewControllerA.presentPanModal(viewControllerB)
|
||||
```
|
||||
|
||||
The presented view controller must conform to `PanModalPresentable` to take advantage of the customizable options
|
||||
|
||||
```swift
|
||||
extension ViewControllerB: PanModalPresentable {
|
||||
|
||||
var panScrollable: UIScrollView? {
|
||||
return nil
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### PanScrollable
|
||||
|
||||
If your view controller has an embedded `UIScrollView` e.g. as is the case with `UITableViewController`, panModal will seamlessly transition pan gestures between the modal and the scroll view
|
||||
|
||||
```swift
|
||||
class ViewControllerC: UITableViewController, PanModalPresentable {
|
||||
|
||||
var panScrollable: UIScrollView? {
|
||||
return tableView
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Adjusting Heights
|
||||
|
||||
Height values of the panModal can be adjusted by overriding `shortFormHeight` or `longFormHeight`
|
||||
|
||||
```swift
|
||||
extension ViewControllerC: PanModalPresentable {
|
||||
|
||||
var shortFormHeight: PanModalHeight {
|
||||
return .contentHeight(300)
|
||||
}
|
||||
|
||||
var longFormHeight: PanModalHeight {
|
||||
return .maxHeightWithTopInset(40)
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Updates at Runtime
|
||||
|
||||
Values are stored during presentation, so when adjusting at runtime you should call `panModalSetNeedsLayoutUpdate()`
|
||||
|
||||
```swift
|
||||
func viewDidLoad() {
|
||||
hasLoaded = true
|
||||
|
||||
panModalSetNeedsLayoutUpdate()
|
||||
panModalTransition(to: .shortForm)
|
||||
}
|
||||
|
||||
var shortFormHeight: PanModalHeight {
|
||||
if hasLoaded {
|
||||
return .contentHeight(200)
|
||||
}
|
||||
return .maxHeight
|
||||
}
|
||||
```
|
||||
|
||||
### Sample App
|
||||
|
||||
Check out the [Sample App](https://github.com/slackhq/PanModal/tree/master/Sample) for more complex configurations of `PanModalPresentable`, including navigation controllers and stacked modals.

## Contributing
|
||||
|
||||
We're glad to be open sourcing this library. We use it in numerous places within the slack app and expect it to be easy to use as well as modify; we've added extensive documentation within the code to support that.
|
||||
|
||||
We will only be fixing critical bugs, thus, for any non-critical issues or feature requests we hope to be able to rely on the community using the library to add what they need. We encourage folks to create forks and are willing to review PR’s created by the community. For more information, please read the [contributing guidelines](https://github.com/slackhq/PanModal/blob/master/CONTRIBUTING.md).
