ios - Dynamically change x and y of a button -

i know if there possible way through can dynamically change position of uibutton depending on screen size of phone(4s, 5-series , 6)

thanks in advance.

there multiple ways solve issue:

1) autolayout can specify rules describe how views relate each other. allow app intelligently adapt screen size, if thoughtfully implemented.

2) can check device version @ runtime , programmatically layout view appropriately.

1 preferred solution, , best practice on ios.
