UITableViewController will automatically resize its UITableView when keyboard is shown/hidden. If your UI has table-like design, you can place your controls inside UITableView so you won't have to implement resizing manually.
Instead, you need to figure out what your common use cases are and then program accordingly. This is object-oriented programming - code reuse is encouraged! But, if you are copying and pasting between projects, you are doing it wrong.
For example, it is very common for me to do this with text inputes in UITableViews that are not part of a UITableView controller. Obviously, the keyboard becomes a problem that I need to fix.So, do I write the necessary code to fix it every time? Nope, I wrote it once in a UITableView subclass and I use that class in all my projects.
Remember, good programmers are lazy and will use the tools available to them to avoid writing the same thing over and over. Create your own class, categories, etc. To handle you common problems and you'll be fine.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
