To start using the component add it to your project using CocoaPods or Swift Package. First of all import FloatingLabelTextFieldSwiftUI
import FloatingLabelTextFieldSwiftUI
struct ContentView: View {
@State private var firstName: String = ""
var body: some View {
FloatingLabelTextField($firstName, placeholder: "First Name", editingChanged: { (isChanged) in
}) {
}.frame(height: 70)
}
}You can customize the colors of the textfield by using FloatingLabelTextFieldStyle property or create your own style and set a few properties.
struct ContentView: View {
@State private var firstName: String = ""
var body: some View {
FloatingLabelTextField($firstName, placeholder: "First Name", editingChanged: { (isChanged) in
}) {
}
.titleColor(.green)
.selectedLineColor(.blue)
.selectedTextColor(.blue)
.selectedTitleColor(.blue)
.frame(height: 70)
}
}Just two step for create and add style to FloatingLabelTextField.
- Create your own theme style. Set property as per your theme.
struct ThemeTextFieldStyle: FloatingLabelTextFieldStyle {
func body(content: FloatingLabelTextField) -> FloatingLabelTextField {
content
.spaceBetweenTitleText(15) // Sets the space between title and text.
.textAlignment(.leading) // Sets the alignment for text.
.lineHeight(1) // Sets the line height.
.selectedLineHeight(1.5) // Sets the selected line height.
.lineColor(.gray) // Sets the line color.
.selectedLineColor(.blue) // Sets the selected line color.
.titleColor(.gray) // Sets the title color.
.selectedTitleColor(.blue) // Sets the selected title color.
.titleFont(.system(size: 12)) // Sets the title font.
.textColor(.black) // Sets the text color.
.selectedTextColor(.blue) // Sets the selected text color.
.textFont(.system(size: 15)) // Sets the text font.
.placeholderColor(.gray) // Sets the placeholder color.
.placeholderFont(.system(size: 15)) // Sets the placeholder font.
.errorColor(.red) // Sets the error color.
.addDisableEditingAction([.paste]) // Disable text field editing action. Like cut, copy, past, all etc.
.enablePlaceholderOnFocus(true) // Enable the placeholder label when the textfield is focused.
.allowsHitTesting(true) // Whether this view participates in hit test operations.
.disabled(false) // Whether users can interact with this.
}
}- Add style to FloatingLabelTextField.
struct ContentView: View {
@State private var firstName: String = ""
var body: some View {
FloatingLabelTextField($firstName, placeholder: "First Name", editingChanged: { (isChanged) in
}) {
}
.floatingStyle(ThemeTextFieldStyle())
.frame(height: 70)
}
}To enable Secure Text Entry use .isSecureTextEntry(true) property.
struct ContentView: View {
@State private var password: String = ""
var body: some View {
HStack(spacing: 20) {
FloatingLabelTextField($password, placeholder: "Password", editingChanged: { (isChanged) in
}) {
}
.isSecureTextEntry(true)
.frame(height: 70)
}
}
}Yes, you can easily add your own views, buttons or image to left view or right view of the FloatingLabelTextField.
struct ContentView: View {
@State private var password: String = ""
@State private var isPasswordShow: Bool = false
var body: some View {
FloatingLabelTextField($password, placeholder: "Password", editingChanged: { (isChanged) in
}) {
}
.isSecureTextEntry(!self.isPasswordShow)
.leftView({ // Add left view.
Image("password")
})
.rightView({ // Add right view.
Button(action: {
withAnimation {
self.isPasswordShow.toggle()
}
}) {
Image(self.isPasswordShow ? "eye_close" : "eye_show")
}
})
.frame(height: 70)
.padding()
}
}FloatingLableTextFieldSwiftUI supports displaying an error and add text field validations. This can be helpfull for adding validation on your form text field. To enable isShowError property to true and pass text field validations array to text field with message according condition. You can also add validation checker variable to check is text field is valid or not on submit button action.
FloatingLabelTextFieldSwiftUI also have some inbuilt validation regex checker fields like email, password, name, number.. etc.
Here is some example
- Email Validation
struct ContentView: View {
@State private var email: String = ""
@State private var isValidEmail: Bool = false
var body: some View {
VStack {
FloatingLabelTextField($email, validtionChecker: $isValidEmail, placeholder: "Email", editingChanged: { (isChanged) in
}) {
}
.addValidation(.init(condition: email.isValid(.email), errorMessage: "Invalid Email")) /// Sets the validation condition.
.isShowError(true) /// Sets the is show error message.
.errorColor(.red) /// Sets the error color.
.keyboardType(.emailAddress)
.frame(height: 70)
.padding()
Button(action: {
self.endEditing(true)
if self.isValidEmail {
print("Valid Email")
} else {
print("Invalid Email")
}
}) {
Text("Create")
}
}
}
}- Name Validation
struct ContentView: View {
@State private var lastName: String = ""
var body: some View {
FloatingLabelTextField($lastName, placeholder: "Last Name", editingChanged: { (isChanged) in
}) {
}
.isShowError(true) /// Sets the is show error message.
.addValidations([.init(condition: lastName.isValid(.alphabet), errorMessage: "Invalid Name"),
.init(condition: lastName.count >= 2, errorMessage: "Minimum two character long")
]) /// Sets the validation conditions.
.floatingStyle(ThemeTextFieldStyle2())
.frame(height: 70)
}
