Get the top left coordinates of a UITextView

I have a UITextView that is a part of scrollView..  What I want to do is get the top left coordinates of the TextView when the user clicks a button.  Can this be accomplished?

Thanks,
Matt

use bounds:
NSRect rect = [myView bounds];
then rect.origin is the origin point (on Mac this is left-bottom corner). This rect contains the size. Add the height to the y.

In order to avoid misunderstanding: myView in the previous comment is the scrollView from your question, it does not change its position and so the bounds and the size do not change.

Thanks for your reply... Do you have convert rect.origin.y to an integer? It keeps returning 0 for me when I try to display with NSLog("Y is: %i", rect.origin.y);

Making Bulk Changes to Active Directory

Watch this video to see how easy it is to make mass changes to Active Directory from an external text file without using complicated scripts.

pgnatyukCommented:
If it's float, print it as float: %f.
NSLog("Y is: %f", rect.origin.y);

If you need it as int, cast it same way as in C: (int), for example:
NSLog("Y is: %i", (int)(rect.origin.y));

This origin is NSPoint, it is a structure, but knows how to "explain itself" with NSStringFromPoint(thePoint).
So you can use:
NSLog(@"Origin %@", NSStringFromPoint(rect.origin));

It is not a correct way to ask the related question, please don't do it this way.

Thanks for your help!

I used the following:

CGRect rect = [scrollView bounds];
NSLog(@"My y is: %f", rect.origin.y);

You are welcome.
I thought you work on Mac and so said about NSRect and about NSStringFromPoint. :)
So please mention it next time and I will not confuse you in my comments.

Best regards
