LAUNCHXL-CC1310: Don't want to use interrupt for button, can I please know if there is any other way to keep waiting for the button to be pressed?

Part Number:LAUNCHXL-CC1310

I have tried working with button press as interrupt many times. The button works fine without my complete code implemented but as soon as my code is introduced the code goes to ISR but only executes 4-5 lines after that. 

I need some input on if I can keep polling the button and once its pressed I need to execute another function and return back.

Thank you.
