Question 1

How to add a shake animation to UITextField in Swift using UITextField-Shake?

Accepted Answer

Import the library via CocoaPods or Carthage, then call the shake method on your UITextField instance. For example, textField.shake(10, withDelta: 5.0) will shake it 10 times with a 5-point width. Customize parameters like speed and direction as shown in the README examples.

Question 2

UITextField-Shake vs writing custom Core Animation code for shake effect?

Accepted Answer

UITextField-Shake saves development time by providing a pre-built, customizable solution, whereas custom Core Animation code offers more flexibility but requires deeper animation knowledge. For simple, consistent shake animations, UITextField-Shake is more efficient and less error-prone.

Question 3

Can I use UITextField-Shake with SwiftUI?

Accepted Answer

No, UITextField-Shake is designed for UIKit's UITextField and does not directly support SwiftUI's TextField. For SwiftUI, you would need to use UIViewRepresentable to wrap a UITextField or seek a SwiftUI-native alternative for similar effects.

Question 4

How to change the shake speed in UITextField-Shake?

Accepted Answer

Use the speed parameter in the shake method. For instance, textField.shake(10, withDelta: 5, speed: 0.03) sets the shake interval to 30ms per movement, allowing precise control over animation pace as detailed in the usage section.

Question 5

Does UITextField-Shake support vertical shaking?

Accepted Answer

Yes, it supports both horizontal and vertical shake directions. Set the shakeDirection parameter to ShakeDirection.Vertical in Swift or ShakeDirectionVertical in Objective-C, as shown in the code examples for custom animations.

Question 6

What are some alternatives to UITextField-Shake for iOS animations?

Accepted Answer

Alternatives include using UIView animations with keyframes, Core Animation directly, or broader libraries like Spring or Lottie for complex effects. However, for a focused, lightweight shake animation on UITextField, UITextField-Shake is specialized and straightforward.
