Answer 1

I think you missed the addsubview the txtAddNew to the Mainview

   txtAddNew.tag = 15;
   [self.view addsubview:txtAddNew];  

   // Open keyboard
  [txtAddNew becomeFirstResponder];

Answer 2

Swift 3

Here is the swift 3 version of the accepted answer. For me to get it to work I also had to add a delay.

txtAddNew.perform(
    #selector(becomeFirstResponder), 
    with: nil, 
    afterDelay: 0.1
)
