theres this problem when i resize the gui its normal at that pc but when i used the emulator the gui is in a diffreant position and size. is there any solution?
Yep, there is the solution to your problem.
You have to learn to size the models with {Those numbers here, not those}, {those, not those}
So an example would be like: {0.12, 0}, {0.12, 0}
.
Remember that if you set it the numbers to the {1, 0}, {1, 0} you will cover the entire screen, so you have to use numbers {0.12, 0} or other... just don't make it over 1.
Im not 100% sure how it works but you need to use 'UIAspectRatioConstraints'.
