Using LDScrollViewForm
To start using LDScrollViewForm in your iOS app, follow these steps:
Step 1: Import LDScrollViewForm
In your Swift file, import the LDScrollViewForm module:
import LDScrollViewForm
Step 2: Create an LDScrollViewForm
Create an instance of LDScrollViewForm and add it to your desired view:
let scrollViewForm = LDScrollViewForm(frame: CGRect(x: 0, y: 0, width: view.frame.width, height: view.frame.height))
view.addSubview(scrollViewForm)
Step 3: Customize the Form
Configure the form by adding form elements, providing titles, and setting up validations if needed:
scrollViewForm.addElement(title: "Name", element: UITextField())
scrollViewForm.addElement(title: "Email", element: UITextField())
// Add more elements as needed
// Set up validations
scrollViewForm.setValidation(for: "Name") { name in
return name.count > 0
}
Step 4: Handle Submit Button Tap
Implement a handler for the submit button tap:
scrollViewForm.onSubmitButtonTapped = {
// Handle form submission here
}
Additional Functionality
Customizing Appearance
You can further customize the appearance of LDScrollViewForm by modifying its properties:
scrollViewForm.backgroundColor
: Set the background color of the form.scrollViewForm.titleFont
: Set the font for element titles.scrollViewForm.titleColor
: Set the color for element titles.scrollViewForm.elementSpacing
: Set the vertical spacing between form elements.
Validating Form Elements
LDScrollViewForm provides a convenient way to validate form elements. You can set up validations for specific elements and define custom rules. Here’s an example:
scrollViewForm.setValidation(for: "Email") { email in
let emailRegex = "YOUR_REGEX_HERE"
let emailPredicate = NSPredicate(format: "SELF MATCHES %@", emailRegex)
return emailPredicate.evaluate(with: email)
}
Automatically Scrolling to Invalid Element
If the user submits the form and there are validation errors, LDScrollViewForm can automatically scroll to the first invalid element. To enable this functionality, use the following property:
scrollViewForm.scrollToInvalidElement = true
