BRDropDownView : "Observe Y offset of targetView, then DropDown and Up Custom UI View that supports various styles."
BRDropDownView is BORING DropDown && Up animated UIView Component that animates dropdown and up depending on Y offset of a View you want to observe, supporting various style of subview type.
## Example
To run the example project, clone the repo, and run `pod install` from the Example directory first.
## Requirements
iOS 9.0 +
Swift 3.0 +
## Installation
BRDropDownView is available through [CocoaPods](http://cocoapods.org). To install
it, simply add the following line to your Podfile:
```ruby
pod 'BRDropDownView'
```
## How to use
BRDropDownView is highly recommend to be used programmatically
see the below code in the included example project.
it is straight-forward to use.
```Swift
import UIKit
import BRDropDownView
class ViewController: UIViewController {
@IBOutlet var tableView: UITableView!
var dropdownViewstyle: DropDownViewStyle = .typeA
let firstOffSet: CGFloat = 0
let secondOffSet: CGFloat = 1000.0
let thirdOffSet: CGFloat = 2000.0
let fourthOffSet: CGFloat = 3000.0
let cellReusableIdentifier = "cellID"
let sampleIdentifier0 = "Sample0"
let sampleIdentifier1 = "Sample1"
let heightOfDropDownView: CGFloat = 100.0
lazy var dropdownView: BRDropDownView = { [unowned self] in
let dropdownView = BRDropDownView(height: heightOfDropDownView,
dropdownViewStyle: dropdownViewstyle)
dropdownView.delegate = self
dropdownView.triggerOffsetY = 20.0
// Top Main 4 Properties
// dropdownView.backButton
// dropdownView.searchButton
// dropdownView.shoppingCartButton
// dropdownView.centerTopNoticeLabel.text = "Custom!"
// dropdownView.centerTopNoticeLabel.textAlignment = .center
// Bottom SubView Properties depending on given 3 style.
switch dropdownViewstyle {
case .typeA:
dropdownView.countdownView.set(seconds:30)
dropdownView.countdownView.didFinish = {
[unowned self] sender in
print("countdown finished!")
}
dropdownView.countdownView.didRepeat = {
[unowned self] sender in
print("countdown repeated!")
}
case .typeB:
dropdownView.leftSubLabel.text = "left"
dropdownView.leftSubLabel.font.withSize(10)
dropdownView.leftSubLabel.textAlignment = .center
dropdownView.leftSubLabel.sizeToFit()
dropdownView.rightSubLabel.text = "right"
dropdownView.rightSubLabel.font.withSize(10)
dropdownView.rightSubLabel.textAlignment = .center
dropdownView.rightSubLabel.sizeToFit()
dropdownView.mainSubLabel.text = "main"
dropdownView.mainSubLabel.font.withSize(14)
dropdownView.mainSubLabel.textAlignment = .center
dropdownView.mainSubLabel.sizeToFit()
case .typeC:
dropdownView.firstSectionLabelTapped = {
[unowned self] in
self.tableView.moveTo(offSet: self.firstOffSet)
}
dropdownView.secondSectionLabelTapped = {
[unowned self] in
self.tableView.moveTo(offSet: self.secondOffSet)
}
dropdownView.thirdSectionLabelTapped = {
[unowned self] in
self.tableView.moveTo(offSet: self.thirdOffSet)
}
dropdownView.fourthSectionLabelTapped = {
[unowned self] in
self.tableView.moveTo(offSet: self.fourthOffSet)
}
}
return dropdownView

}
override func viewDidLoad() {

// Do any additional setup after loading the view, typically from a nib.
tableView.delegate = self
tableView.dataSource = self
tableView.register(UITableViewCell.self, forCellReuseIdentifier: cellReusableIdentifier)
self.view.addSubview(self.dropdownView)

return 100
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = self.tableView.dequeueReusableCell(withIdentifier: cellReusableIdentifier, for: indexPath)
cell.textLabel?.text = "\(indexPath.row)"
cell.imageView?.image = #imageLiteral(resourceName: "image00")
return cell
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 100
}
func scrollViewDidScroll(_ scrollView: UIScrollView) {

}
}
```
Trigger offset Y to make BRDropDownView drop down && up
BRDropDownView animateds dropdown and up depending on triggerOffsetY property.
you can set offset as below.
```Swift
dropdownView.triggerOffsetY = 20.0
```
Style C : Move to offset
By touching 4 sections label on BRDropDown Style C, you can make UITableView move to offset you would like to get.
```Swift
dropdownView.firstSectionLabelTapped = {
[unowned self] in
self.tableView.moveTo(offSet: self.firstOffSet)
}
dropdownView.secondSectionLabelTapped = {
[unowned self] in
self.tableView.moveTo(offSet: self.secondOffSet)
}
dropdownView.thirdSectionLabelTapped = {
[unowned self] in
self.tableView.moveTo(offSet: self.thirdOffSet)
}
dropdownView.fourthSectionLabelTapped = {
[unowned self] in
self.tableView.moveTo(offSet: self.fourthOffSet)
}
```
BRDropDownView can observe scroll offset Y.
depending on offset Y, a proper section is displayed to notify where offset Y is being passed while user scroll table view.
```Swift
func scrollViewDidScroll(_ scrollView: UIScrollView) {
dropdownView.observe(scrollView,
firstSectionOffSet: firstOffSet,
secondSectionOffSet: secondOffSet,
thirdSectionOffSet: thirdOffSet,
fourthSectionOffSet: fourthOffSet)
}
```
BRDropDownView Styles
You can use one of three type as built-in BRDropDownView style.
```Swift
public enum DropDownViewStyle: Int {
case typeA
case typeB
case typeC
}
let dropdownViewstyle: DropDownViewStyle = .typeC
let dropdownView = BRDropDownView(height: 100.0, dropdownViewStyle: dropdownViewstyle)
```
Customize
you can customize BRDropDownView by using exposed APIs.
The example code is below.
```Swift
// Bottom SubView Properties depending on given 3 style.
switch dropdownViewstyle {
case .typeA:
dropdownView.countdownView.set(seconds:30)
dropdownView.countdownView.didFinish = {
[unowned self] sender in
print("countdown finished!")
}
dropdownView.countdownView.didRepeat = {
[unowned self] sender in
print("countdown repeated!")
}
case .typeB:
dropdownView.leftSubLabel.text = "left"
dropdownView.leftSubLabel.font.withSize(10)
dropdownView.leftSubLabel.textAlignment = .center
dropdownView.leftSubLabel.sizeToFit()
dropdownView.rightSubLabel.text = "right"
dropdownView.rightSubLabel.font.withSize(10)
dropdownView.rightSubLabel.textAlignment = .center
dropdownView.rightSubLabel.sizeToFit()
dropdownView.mainSubLabel.text = "main"
dropdownView.mainSubLabel.font.withSize(14)
dropdownView.mainSubLabel.textAlignment = .center
dropdownView.mainSubLabel.sizeToFit()
case .typeC:
dropdownView.firstSectionLabelTapped = {
[unowned self] in
self.tableView.moveTo(offSet: self.firstOffSet)
}
dropdownView.secondSectionLabelTapped = {
[unowned self] in
self.tableView.moveTo(offSet: self.secondOffSet)
}
dropdownView.thirdSectionLabelTapped = {
[unowned self] in
self.tableView.moveTo(offSet: self.thirdOffSet)
}
dropdownView.fourthSectionLabelTapped = {
[unowned self] in
self.tableView.moveTo(offSet: self.fourthOffSet)
}
}
```
BRDropDownViewDelegate Methods
Event can be traditionally notified through delegate.
```Swift
// MARK: - BRDropDownViewDelegate protocols.
public protocol BRDropDownViewDelegate: NSObjectProtocol {
func didDropDownCompleted(sender: BRDropDownView) -> Void
func didDropUpCompleted(sender: BRDropDownView) -> Void
func backButtonDidTouch(sender: BRDropDownView) -> Void
func searchButtonDidTouch(sender: BRDropDownView) -> Void
func shoppingCartButtonDidTouch(sender: BRDropDownView) -> Void
}
....
...
..
.
dropdownView.delegate = self
extension ViewController: BRDropDownViewDelegate {
func didDropUpCompleted(sender: BRDropDownView) {
print("didDropUpCompleted!")
}
func didDropDownCompleted(sender: BRDropDownView) {
print("didDropDownCompleted!")
}
func backButtonDidTouch(sender: BRDropDownView) -> Void {
print("backButtonDidTouch in delegate!")
self.navigationController?.popViewController(animated: true)
}
func searchButtonDidTouch(sender: BRDropDownView) -> Void {
print("searchButtonDidTouch in delegate!")
self.performSegue(withIdentifier: sampleIdentifier0, sender: nil)
}
func shoppingCartButtonDidTouch(sender: BRDropDownView) -> Void {
print("shoppingCartButtonDidTouch in delegate!")
self.performSegue(withIdentifier: sampleIdentifier1, sender: nil)
}
}
```
