I want to call a method of another kind that shows a screen, the problem is that trying to call it from another class does not do anything.
I do it in this way example:
NameClase *c = [[NameClase alloc]init];
[c metodo];
or
[[c init]metodo];
but the screen to help is not shown. and the screen that I want to show if it works.

This way you can call your method by instantiating your object with other classes.
