In today's fast-paced world, smartphones have become an integral part of our lives. Among all the smartphones, the iPhone stands out as a symbol of luxury and high-end technology. With its sleek design and user-friendly interface, the iPhone has been winning hearts all over the world. One of the key features that make the iPhone so popular is its text input functionality, which is enhanced by the use of UITextField.
UITextField is a class in the iOS SDK that provides a text input field where users can enter text. It allows for various customization options, making it the preferred choice for developers when it comes to text input in iPhone apps. However, there is one feature that UITextField lacks, and that is the "clear" button.
The "clear" button is a small "x" icon that appears at the end of the text field and allows users to quickly delete the text they have entered. This feature is particularly useful when the user wants to start over or correct a mistake without having to delete the entire text manually. Unfortunately, UITextField does not have this button by default. But don't worry, in this article, we will show you how to enhance your UITextField by adding the "clear" button.
Step 1: Create a UITextField
The first step is to create a UITextField in your project. You can do this either programmatically or by using the storyboard. If you are using the storyboard, simply drag and drop a UITextField from the object library onto your view controller. If you are creating it programmatically, you can use the following code:
let textField = UITextField(frame: CGRect(x: 50, y: 100, width: 300, height: 50))
self.view.addSubview(textField)
Step 2: Set the UITextField's properties
Next, we need to set the properties of our UITextField. These properties include the font, text color, placeholder text, and any other customization options. You can set these properties according to your app's design and requirements. For example, you can use the following code to set the font and text color of the UITextField:
textField.font = UIFont.systemFont(ofSize: 18)
textField.textColor = UIColor.black
Step 3: Add the "clear" button
Now comes the most crucial part - adding the "clear" button to our UITextField. To do this, we will be using the UITextField's rightView property, which allows us to add a custom view to the right side of the text field. We will be creating a UIButton and setting it as the rightView of our text field. Here's the code for adding the "clear" button:
let clearButton = UIButton(type: .custom)
clearButton.setImage(UIImage(named: "clear_icon"), for: .normal)
clearButton.frame = CGRect(x: 0, y: 0, width: 20, height: 20)
clearButton.addTarget(self, action: #selector(clearText), for: .touchUpInside)
textField.rightView = clearButton
textField.rightViewMode = .always
In the above code, we first create a UIButton and set its image to be the "clear" icon. We then set its frame and add a target for the touchUpInside event. Finally, we set the button as the rightView of our text field and make sure it is always visible using the .always mode.
Step 4: Implement the clearText function
The last step is to implement the clearText function, which will be called when
