iOS TextField

Steps to configure iOS TextField 

• Search the object library for TextField and drag the result to the storyboard.
• For the text field, set one or more targets and actions.
• Customize the text field's keyboard-related features.
• To report the changes made during editing, perform text field delegate object operations.
• When the user changes the content of a text field, the text field delegate method is called.
• Validating the text that the user has entered.
• When the return key on the keyboard is pressed, the Delegate method is invoked.
• Create a text field outlet in the ViewController class that corresponds to it.
   

Below mentioned flowchart incorporated properties of iOS TextField. 

 

 

Now, all the above steps might seem difficult in beginning, but once you will be working on the same everything will run smoothly. 
 

Let us now right jump into the Implementation for better understanding: 

Time for an Example

Step 1: Create a new file in xCode project
 

Click on new file from the navigation bar. 
 

Choose a template for your new file: SwiftUI View
 

Give it any name as per your choice.

Click Create. 
 

 

Now, we are good to go!

Step 2: Let us create our first Input TextField using TextField()

Replace the Text with TextField so that the user can actually type in some information. 

Here we have a whole bunch of different completions here as you can see below.
 

 

To make it simple, we’ll be utilizing StringProtocol and Binding<String> completion.
 

import SwiftUI

struct TextFieldView: View {
    @State var textfield : String = "";

    var body: some View {
        TextField("Type Something here...", text: $textfield)
    }
}

struct TextFieldView_Previews: PreviewProvider {
    static var previews: some View {
        TextFieldView()
    }
}

Now, resume the canvas and look for the changes:

 

Output:

Wohho, we have created our first TextField!

To run this, press the second option. 
 

 

Type something and there you go!

 

You can add multiple features to it to make it look better. 

Let us start by adding padding.

import SwiftUI

struct TextFieldView: View {
    @State var textfield : String = "";

    var body: some View {
        TextField("Type Something here...", text: $textfield).padding()
    }
}

struct TextFieldView_Previews: PreviewProvider {
    static var previews: some View {
        TextFieldView()
    }

 

Output

Looks still dirty?

Let’s try some more styling.

import SwiftUI
struct TextFieldView: View {
    @State var textfield : String = "";

    var body: some View {
        TextField("Type Something here...", text: $textfield).padding().background(Color.orange.opacity(0.5)
            .cornerRadius(10)).foregroundColor(.red)
            .font(.headline)
    }
}

struct TextFieldView_Previews: PreviewProvider {
    static var previews: some View {
        TextFieldView()
    }
}

Output:

Don’t stop here Ninja!. Try on playing with the TextField on your own.
