Property Documentation

- (double) FOV [read, assign]

The field of view (FOV) encompassed by the larger dimension (width or height) of the view in degrees at zoom 1.

This is clamped to the range [1, 160] degrees, and has a default value of 90.

Lower FOV values produce a zooming in effect; larger FOV values produce an fisheye effect.

Note:
This is not the displayed FOV if zoom is anything other than 1. User zoom gestures control the zoom property, not this property.
- (float) zoom [read, assign]

Adjusts the visible region of the screen.

A zoom of N will show the same area as the central width/N height/N area of what is shown at zoom 1.

Zoom is clamped to the implementation defined range [1, 5].

- (GMSOrientation) orientation [read, assign]

The camera orientation, which groups together heading and pitch.
