# isFlipped

A Boolean value indicating whether the view uses a flipped coordinate system.

## Declaration

```swift
var isFlipped: Bool { get }
```

## Discussion

Discussion The default value of this property is false, which results in a non-flipped coordinate system. In a non-flipped coordinate system, the origin is in the lower-left corner of the view and positive y-values extend upward. In a flipped coordinate system, the origin is in the upper-left corner of the view and y-values extend downward. X-values always extend to the right. If you want your view to use a flipped coordinate system, override this property and return true.
