I have created an app which starts with a login page, after entering some user information I send a GET to server. Using the response values I create buttons, their title etc dynamically. Everything is ok, but after I send GET and use the JSON response my buttons are being created on the same view with the login page. I want to also create a new view and create buttons on that view. Since I use some parameters from user information I need to create the view in the same class with my MainViewController (in my case it is BNT_1ViewController) but I can’t figure out how to handle this situation. I’m sharing the code too, maybe it helps.
And a second question, with this code my buttons just move downwards but I want two lines of buttons. How can I change the position of a button in the x axis? I changed those values but the whole column changes, even though I want just to place two buttons in the same line, all the struct replaces..

following are answers of your queries, might be it will help you-
1. I want to also be creating a new view and create buttons on that view.
for this you can create a new view controller and push that view controller once you received the response. Also you can float the response from one controller to other.
2. And a second question, with this code my buttons just move downwards but i want two lines of buttons
You need to set frames of buttons properly, then will work perfectly.
