# modifyAnimations(withRepeatCount:autoreverses:animations:)

Repeats the specified animations a specific number of times, optionally running the animation forward and backward.

## Declaration

```swift
class func modifyAnimations(withRepeatCount count: CGFloat, autoreverses: Bool, animations: () -> Void)
```

## Parameters

- `count`: The number of times to repeat the animations.
- `autoreverses`: A Boolean value that indicates whether the animations run forward and backward.
- `animations`: The animations to perform.

## Discussion

Discussion You must call this method from within an enclosing animation block. The inverse nesting, calling animate(withDuration:animations:) from inside the modifyAnimations(withRepeatCount:autoreverses:animations:) block, doesn’t work. UIView.animate(withDuration: 1.0) {     UIView.modifyAnimations(withRepeatCount: 2, autoreverses: true) {         // Set view properties.     } }
