Encoding & Decoding
MBurgerSwift has a built in system that can be used to init your custom constructs. You have only to make your construct conform to MBDecodable protocol.
For example a News that's reflecting a newsfeed block in MBurger:
class News: MBDecodable {
let text: String
let images: [MBImage]
let link: String
let date: Date
enum DecoderCodingKeys: String, CodingKey {
case text
case images
case link
case date
}
required init(from decoder: MBDecoder) throws {
let container = try decoder.container(keyedBy: DecoderCodingKeys.self)
text = try container.decode(String.self, forKey: .text)
images = try container.decode([MBImage].self, forKey: .images)
link = try container.decode(String.self, forKey: .link)
date = try container.decode(Date.self, forKey: . date)
}
}
And call the decode function of MBDecoder to create and populate an array of news like this:
MBClient.getSections(ofBlock: THE_BLOCK_ID, parameters: nil, elements: true, success: { (sections, _) in
sections.forEach { section in
do {
if let elements = section.elements {
let news = try MBDecoder.decode(News.self, elements: elements)
newsArray.append(news)
}
} catch let error {
self.showError(error)
}
}
}, failure: { error in
self.showError(error)
})
The DecoderCodingKey needs to match to the name of the element in the MBurger block(e.g. if the element on the dashboard is called Title the decoder key needs to be Title):
enum DecoderCodingKeys: String, CodingKey {
case text = "Title"
case images
case link
case date
}
