iphone aspect ratio

In the game screen there is the iphone tall aspect ratio.
Will this option fit for all iphone screens?
If not, how can I do to achieve this?

Thanks

From the Game View Manual page :

The first drop-down on the Game View control bar is the Aspect Drop-down. Here, you can force the aspect ratio of the Game View window to different values. It can be used to test how your game will look on monitors with different aspect ratios.

This aspect ratio is only for testing in the editor, it has no impact on your build. Once you build and install your game, it will adapt automatically to the device’s screen resolution.
