[RxSwift] Delegate Proxy
If you look into the folder named ‘Common’ at [Pods>RxCocoa>]you can find two swift files, DelegateProxy.swift and DelegateProxyType.swift.
DelegateProxy is a bridge that links RxSwift and Swift’s Delegate methods, which helps you to use delegate methods, like UITableViewDelegate and MKMapViewDelegate, in RxSwift/RxCocoa.
Normally we would use MapKit Delegate methods like below
However, with DelegateProxy, we could use methods like the below somehow
In order to achieve that
1. make UICollectionViewDelegateProxy class
2. inherit from the DelegateProxy class
class (name)DelegateProxy
: DelegateProxy<(a class you’ll be using on), (delegate)>
, DelegateProxyType
, (delegate) {
…
}
And then make methods you’ll be using in extension closure
Then that’s it. All you have to do is just listen to those changes like below :)
