# iOS

`BrowserWindowOptions` supports initial content scale, valid orientations,
home-indicator visibility, deferred system-gesture edges, status-bar
visibility.

The same settings can be changed at runtime through Tao's iOS window
extensions.

Screen-edge values are a bitmask: top `1`, left `2`, bottom `4`, and right
`8`.

See [BrowserWindow platform APIs](../api/browser-window#ios-options-and-runtime-extensions).
