<view>.frame.origin does not change Y property

[ivanbuhov]

I'm building a pin login layout.

When each digit is pressed, the view.ios.frame.origin.y property reports 5 no matter where it is on the screen.

A giffy to help explain it

As you can see, no matter which digit I tap the view.ios.frame.origin.y property reports 5.

@roblav96 I can confirm that in your scenario the origin..y is always returning the same value. (origin.x is returning the value as expected).

Code to reproduce this behaviour can be found here

ping @tzraikov

@NickIliev Ye, it's quite strange cause UIView.frame is a native Obj-C property which leads me to think this is Apple's issue? Not sure 👻

[hshristov]

@roblav96 frame property returns rectangle in parent view. Your buttons are in different GridLayouts so their 'y' is the same, only 'x' is different because they are in the same row but different column.
If you want to have different ;origin.y; you could define single GridLayout with 3 columns and 4 rows.

@hshristov @NickIliev Oh sweet! Thank you!

Now I can do this:
