I am trying to slide an image from off the screen onto the screen from the left and stopping at the center point in the view. I would like to keep it contrained at the y position if possible (IE image is set in story board).
I am reading this tutorial, but it is in swift and I cannot make the same assignments in objective-c.

It says to set the view off the screen (in swift):
heading.center.x -= view.bounds.width
Then animate (in swift):
UIView.animateWithDuration(0.5, animations: {
self.heading.center.x += self.view.bounds.width
})
However I cannot manipulate center.x in objective c like they are doing in swift.
I have tried adjusting the initial position of the image in viewWillAppear by changing the bounds with no luck.
EDIT:
Here is what I am trying to get it positioned off the screen:
self.heading.center = CGPointMake(-200, self.heading.center.y);
No matter how negative I set the x position the view will still appears on the screen. Actually no matter what I set x position to the view does not move in the x direction at all. I have also tried to set the frame
The x coordinate of the view's center is not directly assignable in Objective-C. Instead, try setting the center point as whole. In your example, this could look something like this:
