# MFNavigationBarAppearing
[](http://urlaunched.com/)
"the app is developed by [You are launched](https://www.urlaunched.com)"
## Requirements
* Xcode 10+
* iOS 9.0+
* Swift 4.2
## Example
Open and run the **MFNavigationBarAppearing.xcodeproj** in Xcode to see example
## Installation
### CocoaPods
``` ruby
source "https://github.com/Molfar-io/MFPodSpecs.git"
pod 'MFNavigationBarAppearing'
```
### Manual
Add MFNavigationBarAppearing/**Code** folder into your project.
## Usage
First of all you need to setup **content insets** of your scroll view
### Important
You need to use **`MFNavigationBarAppearingController`** instead of UINavigationContoller for presenting your UIViewController. This UIViewController should implement **`MFNavigationBarAppearer`** protocol
```swift
let navigationController = MFNavigationBarAppearingController(rootViewController: UIViewController())
present(navigationController, animated: true, completion: nil)
```
Next step is implement **`MFNavigationBarAppearer`** protocol in your **`UIViewController`**:
```swift
import MFNavigationBarAppearing
//MARK: - MFNavigationBarAppearer
extension UIViewController: MFNavigationBarAppearer {
var appearingScrollView: UIScrollView? {
return scrollView
}
var navigationBarStartAppearingOffset: CGFloat {
return collectionViewContainer.frame.height - collectionViewBottomSpacing
}
var navigationBarEndAppearingOffset: CGFloat? {
return collectionViewContainer.frame.height
}
var appearingTitle: String? {
return place.title?.uppercased()
}
var appearingTitleStartOffsetAfterAppearingNavBar: CGFloat? {
return collectionViewContainer.frame.height + titleLabelTopSpacing
}
var appearingTitleEndOffsetAfterAppearingNavBar: CGFloat? {
return collectionViewContainer.frame.height + placeTitleLabel.frame.height
}
}
```
#### appearingScrollView
It's **UIScrollView** which we will use to handle content offset for calculating appearing state of the navigation bar.
#### navigationBarStartAppearingOffset
The offset from the top of the screen, when you need to start navigation bar appearing.
#### navigationBarEndAppearingOffset (Optional)
The offset when navigation bar appearing should end. If the value is not provided, it will be calculated depending on the height of the navigation bar.
#### appearingTitle (Optional)
The title that will be appearing interactively.
#### appearingTitleStartOffsetAfterAppearingNavBar (Optional)
The offset (delay in pixels) befor starting title appearing. 0 by default.
#### appearingTitleEndOffsetAfterAppearingNavBar (Optional)
The offset when navigation bar appearing should be finish. By default title will be appeared together with navigation bar.
