How to give height from bottom instead of top

Question

I have textview to display some content. I know CGRectMake(10,50,100,100). The 50 is reduce from Top Margin. I need to reduce the from bottom of 50. Where to change the code?

Answer 1

To display the textView while leaving atleast 50px from the bottom, do:

CGRectMake(0, self.view.frame.size.height - 150, 100, 100)

---

self.view.frame.size.height will give you the height of self.view.

Answer 2

Just reduce the height factor CGRectMake(10,50,100,50)
