SwiftForms is a powerful and extremely flexible library written in Swift that allows to create forms by just defining them in a couple of lines. It also provides the ability to customize cells appearance, use custom cells and define your own selector controllers.
#####Here is an screenshot from an example application using SwiftForms
Creating a form using SwiftForms is pretty straightforward. All you need is to derive your controller from FormViewController
and define a FormDescriptor
instance along with its sections and rows. Here is an example of how to create a simple form to input an email and a user password.
// Create form instace
let form = FormDescriptor()
form.title = "Example form"
// Define first section
let section1 = FormSectionDescriptor()
var row: FormRowDescriptor! = FormRowDescriptor(tag: "name", rowType: .Email, title: "Email")
section1.addRow(row)
row = FormRowDescriptor(tag: "pass", rowType: .Password, title: "Password")
section1.addRow(row)
// Define second section
let section2 = FormSectionDescriptor()
row = FormRowDescriptor(tag: "button", rowType: .Button, title: "Submit")
section2.addRow(row)
form.sections = [section1, section2]
self.form = form
To see a more complex form definition you can take a look to the example application.
Every row descriptor has a cellConfiguration dictionary which allows to customize cell appearance by defining its subviews property values using key-value coding.
row.cellConfiguration = ["titleLabel.font" : UIFont.boldSystemFontOfSize(30.0), "segmentedControl.tintColor" : UIColor.redColor()]
In addition, it is possible to create 100% custom cells by deriving from FormBaseCell
class. In that case, don't forget to override configure
and update
methods. First method will be called only once and after cell has been created, and the second one every time cell content should be refreshed.
Here are the methods that help you to define custom cell behavior.
func configure() {
/// override
}
func update() {
/// override
}
class func formRowCellHeight() -> CGFloat {
return 44.0
}
class func formViewController(formViewController: FormViewController, didSelectRow: FormBaseCell) {
}
Once you have defined your custom cell, and in order to use it for a concrete row, you'll have to set FormRowDescriptor
cellClass property.
In order to customize selector controller your class should conform to FormSelector
protocol. That way you'll have access to the cell instance that pushed the controller, being able to alter its properties or setting it's row value accordingly to user interaction.
After defining your class, don't forget to set FormRowDescriptor
selectorControllerClass property to use your custom selector controller.
