| /** | ||
| View of Fastis framework. Use it to create and present dade picker | ||
|
|
||
| Usage example: | ||
| ```swift | ||
| let fastisView = FastisView(mode: .range) | ||
| fastisView.title = "Choose range" | ||
| fastisView.maximumDate = Date() | ||
| fastisView.allowToChooseNilDate = true | ||
| fastisView.shortcuts = [.today, .lastWeek] | ||
| fastisView.dismissHandler = { [weak self] action in | ||
| switch action { | ||
| case .done(let newValue): | ||
| ... | ||
| case .cancel: | ||
| ... | ||
| } | ||
| } | ||
| ``` | ||
|
|
||
| **Single and range modes** | ||
|
|
||
| If you want to get a single date you have to use `Date` type: | ||
|
|
||
| ```swift | ||
| let fastisView = FastisView(mode: .single) | ||
| fastisView.initialValue = Date() | ||
| fastisView.closeOnSelectionImmediately = true | ||
| fastisView.dismissHandler = { [weak self] action in | ||
| switch action { | ||
| case .done(let resultDate): | ||
| print(resultDate) // resultDate is Date | ||
| case .cancel: | ||
| ... | ||
| } | ||
| } | ||
| ``` | ||
|
|
||
| If you want to get a date range you have to use `FastisRange` type: | ||
|
|
||
| ```swift | ||
| let fastisView = FastisView(mode: .range) | ||
| fastisView.initialValue = FastisRange(from: Date(), to: Date()) // or .from(Date(), to: Date()) | ||
| fastisView.dismissHandler = { [weak self] action in | ||
| switch action { | ||
| case .done(let resultRange): | ||
| print(resultRange) // resultRange is FastisRange | ||
| case .cancel: | ||
| ... | ||
| } | ||
| } | ||
| ``` | ||
