iOS - Using with TNS 2.3.0 and Xcode 8

[DomGaud]

After updating to Nativescript 2.3.0 and Xcode 8, I get the following error:

TypeError: UIScreen.mainScreen is not a function. (In 'UIScreen.mainScreen()', 'UIScreen.mainScreen' is an instance of UIScreen)

Solution - change from using a method:

var applicationFrame = UIScreen.mainScreen().applicationFrame;

to a property

var applicationFrame = UIScreen.mainScreen.applicationFrame;

Thanks @DomGaud , for now I will wait for {N} to fully support XCode8 before incorporating the fix in master.

After finding similar cases with other modules, I suggest using utils.ios.getter().

So something like this:

var application = utils.ios.getter(UIScreen, UIScreen.mainScreen)
var applicationFrame = application.applicationFrame

This checks if the property is a function and if it is, calls it on this. Designed to support backward compatibility for methods that became properties. Hence it works with both iOS10 and previous iOS versions. I have tested this using iOS8 as well.

Hey @DomGaud , thanks for the suggestion! I was already planning to change t that but this function is not yet available in the publicly released NPM modules. They are probably going to release it with 2.4 so that's when will update the DropDown.

I actually fixed it locally for me with the answer from @DomGaud and I'm on nativescript 2.3.

@PeterStaev the utility is in 2.3 👍 just hit this today. I've had to use it in a few plugins already.

var utils = require('utils/utils');
var screen = utils.ios.getter(UIScreen, UIScreen.mainScreen);

Thanks guys! Somehow when I initially looked at the definitions I was not seeing the getter() function... New version is now on npm.

Thanks @PeterStaev
